I have finally found a lithium MPPT controller that works out of the box with NO CONFIGURATION. Solar will never be the same.
In this video, I will review and test the basic functionality of a high efficiency MPPT lithium charge controller from Genasun called the GV-10 Lithium or GV-10L. This controller in the video will charge a lithium iron phosphate (LiFePO4) battery with a CC/CV charging profile providing 14.2V. It can handle a maximum input voltage of 34V and will convert that extra voltage into more current into your battery. This model will support up to 10.5A on the input side (roughly 140W).
Genasun is made by Blue Sky Energy. To take a look at their products, go to: genasun.com/ or www.blueskyenergyinc.com/

@LDSreliance 7 лет назад

Yeah I am excited to use this on a regular basis and also to see what else they release soon.

@CncObsession 5 лет назад

I use a Genasun Booster for my golf cart batteries, love it.

@LDSreliance 5 лет назад

Yep, I have one of those, too. Great device.

@FirstLast-ml7yf 4 года назад

Cool. I need one of these. Recently deconstructed/rebuilt a Headway LIFP04 ebike pack from 48V 16S to 12V 4S4P for my trolling motor on my canoe, with a BMS. This is just what I need to get the odd fishing trip in with my battery on sunny summer days, while being off grid and also using the battery for house battery in my van. I've got another one to build too from by buddy's old ebike battery, and will probably output them in parallel through a diode to isolate them. Onward...

@catchbay 7 лет назад

Hello, I have few of those but li-ion 4S models. 160W panels to 4S36P batteries. Made for my father's electric boat. He's out now with boat, 2-3 weeks trip, those give all the energy for motor (torqeedo), fridge (waeco) and navigation (iPad). When I bought first one the company was Genasun, now it's Blue Sky or something. The product is still good and got one replacement unit free, just paid the postage to here at Finland.

@LDSreliance 7 лет назад

Yes, Genasun and Blue Sky Energy are the same company now. They still have two separate websites but they are the same. Glad to hear that they gave you good support and that you like their products!

@bdv861 6 лет назад

Great to see USA made. It would have been nice to see input and output volts/amps while charging just to confirm that it is truly MPPT.

@joeshmoe781 2 года назад

This little board does all you want. A full green LED means fully charged. A blinking green LED means its charging. The faster the better. This charger is one of the most efficient I have found. It adjusts 20 times a second. You can pretty much watch it by the rate the light blinks. Buy a small watt hour meter. Put it in line. It will tell you maximum volts and amps. IT will tell you current volts and amps. It can be reset daily or hourly or more minute if you are anal. Where I live in California with trees and the sun moving in the sky, I say get an mppt controller. If you live where it is sun all day long don't waste your money, buy a pwm controller. The cool thing about this controller is you buy one each for every panel you run. That way they all run most efficiently.

@7armedoctopus69 4 года назад

Would love a vid explaining mppt vs pwn controllers

@gordonsgreatoutdoors7523 7 лет назад

Great review, hopefully get one of these in the UK soon! Quick question: Which are the best charge controllers to support Lithium please? If price wasn't an option, which would you recommend? Thanks for your help and great videos.

@LDSreliance 7 лет назад

This is the only one I know of that will support Lithium natively. Most of the big name solar controller companies "support" Lithium but you have to go into the configuration of the controller and set your own parameters. They also say that you are using at your own risk (i.e. we won't support this if you have problems or hurt yourself). So this is what I would currently recommend if you want an MPPT controller. I will be doing a review on a PWM controller like this soon. And Genasun is planning on releasing a bigger lithium controller that will compete with the big 60A offerings from Outback and Midnite and Morningstar in about a year or so.

@SyberPrepper 7 лет назад

Appreciate the video.

@LDSreliance 7 лет назад

Thanks! I appreciate you watching it.

@giottodiotto1 6 лет назад

about floating lithium batteries, best longtime storage regime for these kind of batts is to store them around 50 percent charged, so since the resting voltage of a 12v nominal LFP batterie is 13.3 volts for a 4s lifepo4 batterie i would floud them at no higher than 13,4 volts....allso do not chage them each time to the brim, better regime would be to use a end of charge around 14 volts, i set my controller to stop charge at 13.9 volts, this wil charge the battery 90 percent full , but will not stress the batterie excesively

@LDSreliance 6 лет назад

I agree with you for long term storage but I don't know about leaving off at 90% SoC. The battery manufacturers and engineers I work with have never mentioned that at all. And all lithium charge controllers on the market will charge them fully.

@ekoms108 5 лет назад

LFP is 12.8v nominal

@rootvalley2 3 месяца назад

I have an exercise bike generator made from a treadmill motor, the issue is in my setup I can't spin the generator fast enough to make high voltage, from the specs it looks like this controller will work I can't wait to try it out.

@LDSreliance 3 месяца назад

Can you change the gearing on the treadmill motor setup to drive the generator faster? I hope the Genasun works out well for you.

@DenHoak 6 лет назад

How many batteries can you run in series with this charge controller. I have (use)5- 12 volt valence u1-12xp and 12rt 40amp in series?? For my sailboat...

@LDSreliance 6 лет назад

In series? Just one. This is a 12V charge controller so if you wired up more than one 12V battery in series you would exceed the input voltage of the controller. There are other MPPT controllers that can handle a much higher voltage but they are more expensive. Why do you want them all in series?

@debirudolph2970 6 лет назад

Hi. Total solar newbie here, and we're trying to set up a panel to a Ryobi charger so we can charge a series of 18V tools in our community garden where there is no power. We've purchased a 100W panel, the tools, a Ryobi charger, 2- 4Ah batteries, and a controller with variable settings, but the charger is too sophisticated to be hooked directly from the panel and controller. Would this controller work between the Ryobi charger and the panel? An electrician buddy has suggested buying a 12V car charger and hooking that up to the panel, but someone else has suggested we'd still need a converter in there to step the power down. Would this controller work in that application?? Any help you or the community could offer would be GREATLY appreciated.

@LDSreliance 6 лет назад

Your RYOBI tool charger will require 110V AC power like you would find in your garage or home. So you will need an inverter for that. You can purchase a cheap one like this that will meet your needs: amzn.to/2PeaNEL If what you are calling a controller is a charge controller like I showed in the video then that is good. You will need that and you will also need a deep cycle battery to store the power. If you don't have a battery then you cannot make this work. An inverter cannot be directly connected to the charge controller or the solar panel. It doesn't have to be big unless you want the power tool charger to charge overnight or something. Something like this should be sufficient: amzn.to/2Nray93 So the solar panel will connect to the charge controller. The charge controller will store that power in the deep cycle battery. The inverter will connect to the deep cycle battery. The inverter will then provide 110V AC power to your RYOBI charger for charging.

@3dmixer552 5 лет назад

You can achieve this with any charge controller that has user settings. Which means that you can set the required bulk and float charge that is required by data sheet. 14.2 is low for lifepo4 batteries. My batteries are valence lifepo4 and by the data sheet it has to be charged at 14.6v bulk and 13.8v float. Paying over 100 buck for something that does not even have a function to set the required voltage is not very smart move

@ekoms108 5 лет назад

Also. Something like Victron MPPT, you can set at what voltage on the battery you go into float mode. That way you you could stop the bulk charge at say 90% capacity, because fully charging lithium shortens it life.

@donboettcher8900 5 лет назад

I would say just the opposite. There is no need to go to 14.2 or 14.6v when charging LiFeP04 batteries when a full charge can be achieved at 13.8-14.0v. Why shove the battery into the upper knee for no reason? No reason for it unless your BMS requires a slightly higher voltage before cell balancing takes place but that is a whole new kettle of fish. What are the individual cell voltages at 14.6v, 3.65, 3.65, 3.65, 3.65? Or might it be something like 3.65, 3.40, 3.55, 4.00? The latter can destroy a battery very quickly.

@naijawindandsolar 7 лет назад

What is the voltage for 1 cell at full charge? I thought it should be 4.2v so 4s should be 16.8v. 14.2v full charge voltage means each of the cells are at 3.7v

@LDSreliance 7 лет назад

Yes 3.6-3.7V is the maximum charge per cell. Nominal voltage is 3.2V. You may be thinking of LiPo which is 4.2V.

@javieruriel 3 года назад

Do you sell also the charge controller in your website?

@LDSreliance 3 года назад

Yes. I only have a couple models listed on the store but there are many more in their catalog. For that battery that I linked you to you would want the GV-10-Li-14.2V or the GV-5-Li-14.2V depending on the solar panel you are using. The GV-5 can handle up to 65W panels and the GV-10 can handle up to 140W panels. The GV-5 is $99 and the GV-10 is $135 retail but if you buy the battery as well I'll throw in a discount coupon. Shoot me an email at ldsreliance@gmail.com if you are interested.

@DavidSmith-dm8ew 7 лет назад

I use home made packs of 18650's at 12.6V for my solar and I would like something in the 40Amp charge range with built in bms for say 300+ah packs. There is currently nothing out that does that.

@LDSreliance 7 лет назад

Yeah, I know. This is the first I have found like I said in the video so more sophisticated products will come. We all need to support these companies making great products and supporting new technologies so that they will make more in the future.

@zachreyhelmberger894 5 лет назад

Do they have a 60 Amp version that can handle a PV array upto 150Volts for 24V battery banks?

@LDSreliance 5 лет назад

I'm confused by your question. 150V but using a 24V battery bank? They do have higher current models under their Blue Sky Energy line.

@zachreyhelmberger894 5 лет назад

@@LDSreliance An MPPT charge controller can take in power from an array, usually up to 150 Volts and step it down to the battery voltage with surprisingly high efficiency. It's a pretty sweet technology. But I am trying to find a controller that has LiFePO4 in mind. I am struggling with an old MX60 controller that is doing all kinds of weird things to a 24V Kilovault battery bank.

@LDSreliance 5 лет назад

I see. No, Genasun does not have a product like that. There are relatively few on the market that can do that with that much current. The MorningStar TS-MPPT-60 is one that I use. There is also the Midnite Solar Classic and the Outback Flexmax. I think there are a few others. I don't have a lot of personal experience with anything but MorningStar, though.

@OH8STN 7 лет назад

How do you connect a load to that controller?

@LDSreliance 7 лет назад

You can't. This model does not have load control functions or terminals.

@OH8STN 7 лет назад

LDSreliance Fair enough. I'm using the gv-5 for lithium iron phosphate (LiFePO4). The reason I didn't buy the 10A app version was it lacked those load ports. Now I'm happily using my radio and charging my 10 amp hour battery pack at the same time with the gv5. Thanks for answering and it's nice to see your channel doing so well. Julian aka STN

@LDSreliance 7 лет назад

Nice. Yeah I was a bit surprised that they didn't have load terminals on it when I received it but then again maybe they are trying to keep costs down. They have to compete with all of these cheapo Chinese MPPT knockoffs, many of which are fake MPPT, and so if they load it with features and charge $200 very few people will buy it. That is just my guess. Either way it is a great line of products!

@johnpwmcgrath 4 года назад

I thought you would wire in the load in parallel with the battery

@jacobcastro1885 4 года назад

I spoke to Ryan @ Genasun yesterday. He said there was something about low voltage disconnect. I've read through the manuals for both, and looks like I still need clarification. Looking to understand these in and out, maybe become a distributor or dealer.

@javieruriel 3 года назад

Excuse me where did you bought that batteries?

I want to design a portable 12V, outdoor, solar / battery powered swamp cooler. I will be four 12V, 100W, 7A portable briefcase solar panels to power two 12V, 120W, 10A automotive radiator fans connected to one or two motor speed controllers (potentiometers), and to power a 12V 3A submersible water pump. I want to use lithium ion batteries, but i do not know what type of lithium ion batteries would be best. Question: What type / brand of MPPT solar charge controller would you recommend I buy / implement for my portable swamp cooler project?

@LDSreliance Год назад

I wouldn't consider anything other than lithium iron phosphate batteries. I have quite a few on my website if you are interested (store.ldsreliance.com). Anyways, this video is a bit older and since that time there are lots more lithium solar charge controllers to choose from. Since this will be subject to humidity I would look for one like the Genasun in this video or the Morningstar SunSaver series that are completely sealed from dust and moisture. Most are not. Also, be leery of any charge controllers below $100 that claim to have MPPT. They are almost guaranteed to be lying.

@bradlyons7046 Год назад

@@LDSreliance What is your opinion of the new Renogy Rego 60A Plug and Play Solar Charge Controller ($438.99 on Amazon)? It does not need programming for any type of battery, including lithium ion type batteries. I will certainly consider buying my lithium ion batteries from you.

@LDSreliance Год назад

I'm not a huge Renogy fan. That unit, for instance, says 60A on it but can only handle 50A input from the solar side. Also, 100V is pretty low maximum voltage. I also can't see any IP (intrusion prevention) rating which would indicate whether it would be suitable to use near a swamp cooler where the humidity will be high. And they don't list how fast the MPPT algorithm samples. The good MPPT controllers will sample every second or sometimes even faster. The average to bad ones will sample once a minute or slower. That matters because the voltage in a solar panel system is constantly moving up and down as conditions change, shadows move across panels, and clouds go in and out of clouds. A controller that can sample every second will keep that max power in alignment whereas a slower controller will lose several percentage points of power over the course of a day. My guess is Renogy put their effort into bells and whistles like the Bluetooth and "plug and play" installation. But they made the connections proprietary so you need adapter cables for most any standard solar equipment.

@JoseGarcia-px9xj 6 лет назад

this look like very basic, what about 48 V battery bank, what about 40a,60a, or 80amp

@LDSreliance 6 лет назад

Genasun only makes controllers for smaller setups. Their sister company, Blue Sky Energy, makes the big boys. They have chosen not to make products that compete with each other but they are owned and run by the same people.

@andrewgervais3039 6 лет назад

Does it float charge the lithium batteries?

@LDSreliance 6 лет назад

Yes it does.

@andrewgervais3039 6 лет назад

Any thoughts on why they would give it a float function? Don't lithium batteries dislike being float charged?

@LDSreliance 6 лет назад

That is something that is still debated in the industry. Some manufacturers say to do it and some say not to. I have not read anything to this point that says it is bad, necessarily. Just may not be necessary. Good question, though.

@LDSreliance 6 лет назад

There are lots of controllers that are adjustable. But the point is that there are and were still relatively few lithium controllers that work out of the box with no adjustments necessary.

@3dmixer552 5 лет назад

@@LDSreliance don't be naive. All you bought is a charge controller with fixed settings and printed on the box. "LITHIUM ION CHARGE CONTROLLER" nothing else.

@tedlanz5038 5 лет назад

Just because it says that the parameters are user adjustable does not mean that the device will follow those settings. There is a video of someone checking exactly this with 6 different mppt chargers and he found only 2 worked!!! Have you double checked the outputs of your rig? It might be ignoring the float charge level.

@LDSreliance 6 лет назад

12V is the most common voltage for solar. There are far more small systems than there ever will be larger systems. Every street sign, construction sign, oil & gas meter, garden pond pump, and automatic gate opener around here all use 12V. Lithium Ion isn't worth it for solar unless you spend big bucks for a Tesla Powerwall. Lithium Iron Phosphate is a much better solution.

@jackcoleman5618 3 года назад

@prspastor 3 года назад

I’d be interested to know why you said that. Because of his comment at the end about the battery being safe? He is using a Lithium iron phosphate LiFePo battery here, and they are generally pretty safe and stable. Lithium polymer LiPo batteries can be dangerous if they are damaged and can catch fire. Lithium ion batteries can run away and cause fires. However he isn’t using the latter two types. Regarding lithium, yes it is a reactive metal but that’s what makes them a powerful battery as well. But they don’t use pure lithium in these batteries. It is an intercalated compound that is less reactive.

I intended the additional information with question(s) be read and replied to, by only you because in your previous reply, you did not recommend a specific model and amp limit of a Genasun or other brand MPPT charge controller for my application (a portable 12-volt, solar powered swamp cooler) Please provide me with the specific model and amp capacity of a Genasun MPPT charge controller and a specific brand and amp hours of a lithium battery I can order through you or wherever you want me to order it from. I viewed every Genasun MPPT charge controller on Amazon, but I did not see any that would have enough amp capacity to know for sure whether or not it would be compatible with my application. I presume I first need to decide what lithium battery to buy, but I need you to recommend a specific brand and the number of amp hours required for my application. For this reason, I included more detailed information about my intended design specs of a portable 12V, outdoor swamp cooler with hope that you would recommend a specific model and amp capacity of a Genasun MPPT charge controller or other brand charge controller and recommend a specific brand and amp hour lithium battery for my application. As you know, I need an MPPT charge controller that is weather-proof because the swamp cooler will be for outdoor use only. The swamp cooler will not be used when there is no sunlight. It will be used in remote wilderness areas where there is no wi-fi signal. Please provide me with the specific model number of an appropriate MPPT charge controller with the required amp capacity for my application, and the specific brand and amp hours of a lithium battery for my application. I promise I will purchase everything I can from you. If you need additional information before recommending a specific model of Genosun MPPT charge controller and specific brand and amp hours of a lithium battery for my application, please let me know. Thank you. Sincerely, Bradley Lyons

@LDSreliance Год назад

This would be best through email. Shoot me an email at ldsreliance@gmail.com. Also, I need to know how long you would like to power your device (160W at most load) so I can size a battery for that length of time. Within reason, of course. If you want to run it for days then your solar panels will be wholly inadequate to recharge a large battery.
