I have been testing portable charge controllers for Ham radio for many years and followed your advice. I went through maybe 4-5 controllers and they were from bad to insanely bad. Then couple years back took your advice on Genasun. Wow! Game changer MPPT. All I get is insignificant RF on 10m. I never tested 6m or 160m. But from testing if 80m not an issue nor will 160m. I did have a Buddipole Mini solar controller that finally died. Nice but expensive unit. Limitations were it’s not MPPT and it’s max solar line voltage and current are very limited to 150w panel and below. But still great concept and works well especially for 100w and less. . But Genasun is less expensive and far more robust and efficient too. Always great content you do. Thank you !

Great as always Julian! Genasun is definitely the way to go. I have a stack of them for my Powerfilm Solar solar panels. They're also very receptive to emails asking questions about specific applications and definitely steer you in the right direction. By the way, your videos are never too long! You could easily add a few more minutes of Snapper and no one would ever complain! Hope you had a great birthday last month brother, Semper fi! Todd KI5HNX

This is quite useful information - I've had solar panels on small boats discussions with my friends over time, and I've never had time or energy to suggest anything else but Victron. These Genasun controllers look very much what is reasonable in many cases - small boats aren't that far from backpacking, except that often they are hesitating on getting a LiFePO4 battery due to price, even if they come with obvious benefits and operating environment basically never gets below freezing.

In addition to the Genasun brand solar controllers, Sunforge has its Blue Sky brand controllers, which go up to 20-25A for 12V systems. It would be useful to know whether they are RF quieter than Victron controllers which you have tested.

@OH8STN 6 месяцев назад

Sadly, they are not RF quiet. Great question 👍

@skinosensei 6 месяцев назад

Better, or worse than Victron controllers?@@OH8STN

@skinosensei 6 месяцев назад

The Blue Sky documentation says, "To comply with electromagnetic compatibility requirements..." to install "ferrite suppressors”. Has anyone tried and tested it?

@OH8STN 6 месяцев назад

Their engineers said the Blue Sky controllers are nowhere near as quiet as Genasun. I haven't tested them myself, just gave them the requirements. Based on their feedback minded in both the ordering one.

@djfmitv 2 месяца назад

The main problem I have with Genasun is that (especially in the UK) they are very pricey for what they are, and their aphiliated stores add on shipping AFTER you've already paid for the item, which causes an error in the payment process (they wanted to charge £40 shipping on top of their lowest-cost model at approx £100, which in total is nearly £140! 😨). If they were to come down to somewhere like £50 per unit, then it would make sense - but on a small-scale 'on-the-move' charging system, it costs more than the batteries and panels do. Is this because of a lack of competition that their prices are so sky-high??

@OH8STN 2 месяца назад

www.genasun.eu is in Netherlands. Shipping to me is quite reasonable, and is calculated at checkout, not after. There are cheaper controllers, but then you have to deal with a noise. If someone made an rf quiet charge controller with good performance at a lower price, I would certainly buy it. Sadly we are paying for the engineering.

@geekdownrange 7 месяцев назад

Now if we could just get Genasun to make a 20-30A controller for small fixed/mobile sites. I know we can parallel multiple controllers. My engineering heart wants something a bit cleaner.

@georgedandrade-hp1gds296 7 месяцев назад

With a solar panel of 20v max 100watts, into 10 amp solar charger, and the bms with lifepo4. I have realize that when the battery when full, the system bypass the battery power of 12.8v and as it is full bypass and get full power of the solar panel 20v. In case that always have the radio connected to the system the radio will get 20v getting overvoltage. Who in the system should cancel the bypass and avoid that overcharge in output on the battery system?

@OH8STN 7 месяцев назад

I've experienced this once myself. The problem is not having the correct charge controller voltage, set under the bms high voltage disconnect voltage. If the high voltage disconnect of your battery is eg 14.6 volts, uour charge controller should be set for 14.4 volts. For my power queen batteries the high voltage is fourteen point four volts, So my charge controllers are usually set between 14.2-14.4 volts. It all depends on the high voltage disconnect voltage. This will prevent that bms going into high voltage disconnect. It's also important to point out that not all charge controllers root raw solar on the battery output. Excellent point 👍 73 Julian oh8stn

@janiceemery2008 7 месяцев назад

Thank you so very much for sharing Julian, I am in the market for a portable battery and charge controller for my FT-991A. I know this is not too portable of a radio but, I would like to get myself setup for off grid communication. If you buy a MPPT charger, do you need to have MPPT solar panels? Thank you again Julian for sharing.

@OH8STN 7 месяцев назад

That's a great question! As long as your solar panels are below the maximum voltage & current of the charge controller, They will be fine. 💪👍 Thanks for watching, Commenting anne for the kindness. It's greatly appreciated.

Hi Julian, I enjoy all your videos and posts. I see in this video that you have a couple of the GVB-8 (Boost) Lithium charge controllers controllers. I would really be interest in seeing a full review of your testing and best use cases for these controllers. What is your assessment of the best use case of the Boost Controllers, and how to best test them. I haven't been able to fully test mine yet, but if I substitute a variable power supply for the panel input, it doesn't seem to like voltages above 13.5 vdc or so. Yet it seems to be working with my SunPower 100W flexible panel. I cant test properly because I'm not getting much sun light this time of year (Canada) through my window. The panel is new, so haven't had a chance to deploy it outdoors for testing yet. But, would appreciate your assessment of these controllers. Thanks, Jeff - ve7eff

Hi Julian, does that mean that the BuddyPole mini 2 is not RF quiet?

@OH8STN 5 месяцев назад

It's quiet in the ham bands because of the added filtering. I found it not to be quiet outside of ham bands. The bigger problem is performance. It's great in California. Awful at higher latitudes. The powerpoles are nice but performance is more important (for me).

@truhartwood3170 5 месяцев назад

Julian - I'm a bit confused on using the Genasun vs something like the Buddipole PowerMini 2. It seems like the PM2 would be better for multiple power inputs (solar, 12V car plug, wall charger, etc.) where it can automatically switch from one power source or another or use both. It also lets you plug two loads in, which lets you avoid a power distribution block if you only have two things you're connecting, or you could have two different power distribution blocks that you could shut down independently. Also, I didn't understand how a PM2 would work with a Bioenno, since they have one connector for power in, and one for power out, whereas the PM2 has one connector to the battery that will either put energy if or pull it out. If that works with the single Bioenno "In" (either putting energy in or pulling it out), can you still use the Bioenno's "out" as a third load connector? It seems the Genasun is better for when your only power source is solar, you're charging one battery like a Bioenno, and that output is hooked up to one load or power distribution bar. But the PM2 would be better for automatically managing a more complicated setup. Maybe you could do a video on that? Thanks for everything you're doing!

@OH8STN 5 месяцев назад

Short answer: Don't let the hype fool you! There are two good things about that charge controller. 1. Dual outputs. 2. Displayed battery information. The PWM charging doesn't work well and will always be outperformed by an MPPT controller. The PM has terrible low light performance, as it starts charging much later than a Genasun controller connected to an identical solar panel. My personal experience with the PM is: Stick with a controller that is designed to collect solar energy. If you need more outputs, build a multi-output cable. I don't want to crap on buddipole, but. My attempts to share ideas on how to improve that charge controller got shut down. They are extremely narrow-minded and easily insulted when shown to be out of their debth. If they would put a Genasun controller inside that box, I would promote it everyday all day. Finally people buy it because it has dual outputs and an information display. Sadly , most of the same people don't understand how poorly it performs as a charge controller.

@truhartwood3170 5 месяцев назад

@@OH8STN Got it, thanks! It does sound like you can give multiple power inputs into the Genasun, they should just be higher voltage (14.5 - 15V at least, though not exceeding the maximum voltage or max amperage, unless you get a boost model (those just seem to have a wider voltage they can work with? The regular one says it can go down to 8V, so it does have some boost, just not as much as the boost model that can go down to 5V). You would just have to switch between the sources manually, and you couldn't use two sources at once. There are various adapters for cars or wall outlets that you can choose a higher voltage for, so those would work to plug into a switch to select between them, and then that into the Genasun to let it handle the battery charging part. I probably spend more time thinking about how to power my gear than I do the gear itself! It's all a bunch of paper weights if there's no power going to it, right?
