Great example of how to build this type setup, I’m finally starting to understand Solar. Thanks for sharing.

My Redodo mini battery ran a 1/3 HP sump pump, pumping water every 15 mins for about 34 hours, battery now at 20%. Maybe 15’ water head pressure on pump. 👍

I have four of the regular size version of redod and 100/50 victron running the 12v version of reliable. Been running it everyday for my house. Great little pourmans setup. The victron controller really is the best . Had a chinesium before not worth a 💩. Good video 👍

Nice!! I've got 2 12v LifePo4 1st version Powerqueen Premiums hooked in parallel with same inverter but 2000watt in my older truck camper. They seem to power up a 5000 BTU window ac and the rv really well. I just need to do the Solar next after resealing the whole camper.

Great video of a simple setup , making use of mini size battery in a 24V system.

Electroboom would definitely go for the largest sparks.

Hi Brad, nice video to show how easy it is. It's not recommended to have the fuse like that though. It bends the metal part that should melt, causing it to potentially malfunction. It's a 125A fuse but it should be 160A.

Not bad. I would make three adjustments. First, use an ANL fuse for the main battery fuse (and note that an even higher-end T-class fuse is not necessary for a small system like this). Second and more importantly... when doing a 24V system from scratch, buy a 24V LiFePO4 battery. Don't use 2 x 12V batteries in series. I would go as far as to say when doing everything from scratch, just go straight to 48V and be done with it. Even for a small system. System expansion is also a lot easier as additional batteries can simply be added in parallel. Series x parallel battery setups with LiFePO4 have issues. And finally, make sure the inverter's low-voltage cut-off occurs before the battery BMS's low-voltage cut-off (usually it does). Or program the charge controller's relay output to shut the inverter down on low-voltage, again before the battery's low-voltage protection engages. Now if you don't have a choice and have to use two 12V batteries in series, you do need a whole battery balancer (which is cheap). Otherwise you are going to run into problems down the line. But it is best to avoid all the issues related to putting LiFePO4 batteries with independent BMS's in series and just get a native 24V battery. All the equipment is available in 24V and 48V these days and basically just as cheap.

2 questions Brad. I've always wanted to connect a fuse straight to the terminal instead of having a fuse in between 2 cables but I have read everywhere that's it not recommended unless you use a terminal fuse. You're the first person I've seen connecting the fuse straight to the terminals. 2) Why did you connect the cables from the mppt to the inverter where everyone else(including myself) connect them to the batteries ?

Great video! This is such a helpful and easy to understand explanation.

That AC unit is capable of pulling over 1300 watts when it's on full blast. I have the same Midea unit with my off grid setup.

Nice little compact system. I like the idea of these mini batteries, but I am having a hard to being a believer in them just because they are so small. Curious to see how these hold up over time.

Very neat setup. Nice one Brad - very simple but 100% on the money. I guess a strap over the batteries for a little more security and you could mount it vertically permanently, say in an RV. 2560WH and weighs around 40kg I expect - pretty good. I thought about arranging it differently to have the inverter the right way up - I think if you put the inverter on the left with the input terminals facing to the right?

Nice, I still don't understand what the MPT thing and the Shunt thing does, but I'll find a video where they explain the components. Nice and easy setup though, that helps!

I need a setup like this to run a portable a/c or inverter powered window unit, for when the hurricanes knock out my power. they pull 450 to 200 watts depending on fan speed.

Very informative! I really thought that you have to connect your charger controller cables to the battery terminals? I see you connected yours to the inverter?

tomorow i m checking a new 100/20... cost was ok but couldnt afford more . i guess little bit of more time charging wont hurt anyone!!!! will try similar setup until i make my own 48v rack!!!

My brother it looks neat. For me though I wouldn't be comfortable having the hot air from the inverter fan blowing on the charge controller. I am imaging all kind of future problems with the charge controller, mine you I maybe wrong.

I had roughly the same idea system thanks for showing.

When does the case ground on the left side of the victron need to be connected?

For the same setup, is it possible to replace the power inverter with a Power Station (E.g Ecoflow) so that these two batteries can be used as an expansion to the Power Station, they supply 24V directly to the Power Station for its charging. How would anyone comment this configuration, pls.

Do you have a link to the shunt?

6:00 aww cmon i wanted to see the sparks haha

I would like your thought on a low budget system for someone just getting into solar for backup and possibly mining with cell phone? Like your channel and keep on doing it! 🙂

Thanks for a nice and clear instruction set. I watched your previous video and as I'm a newbie, I appreciate your warning of the warm blade fuse! I'm using lead acid batteries instead, so is that a big difference?

This is cool. What btu is the a/c system and have u done a test to see how long it will run on low or high before batteries are low? If not can u, i would like to see and also like to see how long it will run with solar coming in and with out any solar.

Do you have a link for solar panels?

Hello! Thank you for very informative video. Why some people use big invertors with screens and some use car inverters like yours? What is the difference?

So this 12000 btu only half the wattage its uses?

Nice.

Newbie question - what drives needing 24v or 48v vs 12 volt when it comes to a solar setup?

If I try this system and I really do want to eventually I’m curious about how you would wire the panels for instance could I wire six 100 W Renorgy Solar panels in series series parallel, and then power that charge controller that way it just make sure that I would hook the charge controller up first to the 24 V batteries source so it would know what it was dealing with and the 600 watts coming in from the array would power it or do I have to wire the panels a special way?

That's a very compact system here. I love it. Btw, how's this inverter? I am thinking to get the 1500w one. is it reliable? the feedbacks on amazon are like 50/50. Any good 24v inverter recommended? Thank you

Plan building this system to run a freezer and ref. during power outages, but plan on using a 24v 200amp hour battery. My question would be would the inverter be able to run for several days continuously if needed and if I keep the battery charged. I had rather spend more on an inverter that would not get hot and shut down. Your video keeps it simple, for me. Thanks! New Sub...

I have a question about battery size-everyone uses just 100ah batterys , can you use higher ah batterys in series to create a larger system would I get more ah/watt hours? all I have is 700 watt heater keeping my 12x24 workshop somewhat warm in the winter with alot of cloudy days in the winter (UP Michigan)

Does it matter which resistor to buy for this?

Hey brad my 150.70 is working great my 100.30 is great but i bought a 100.50 victron and it wont connect. I tried the 1234. 0000. 000000. None will let it connect. My amazon warranty has run out. Do you know any trick to reset it or make it connect?

Hi, thanks for the video. Can I ask more about the shunt? What size and or power was it? Thank you!

Are you increasing the preset setting on the victron. I've turned my absorption voltage up to 28.88. Was this a mistake.

can I use a a regular car battery I have a red top optima

These are great vids! I do have a question about the resistor... you don't like to it. Anything special, link, to use?

what size wires are you using? 3000w at 24v is 125a. how big is the fuse? have you tried a max load?

how long would either the 12v or 24v setup run a dc compressor fridge with 100AH? as long as it will run one for more than 19 hours with no sun, you should be good, even for winter sun hours.

I am thinking to get this victron 100/30 connected to anderson on licitty bat box for 400w single panel so instead of max 6 awg cable cab i make with 10awg from victron to anderson on the licitty box is it safe ? Or better get 6awg but then need to buy good crimp for thick cable

Do you have to disconnect the batteries, to recharge individually every time because they won't charge evenly

Have you found the shunt to be a good alternative to the Victron? If so can you provide more information?

Why not charge them up in parallel?

Are the two Mini batteries smaller than one 200AH Redodo battery?

👍👍

What solar panels are you using?

i have a anl fuse,do i install the Washers to with the bold or i dont need it?

Nice setup Brad. I see Reliable makes that inverter in 12v what are the advantages of 24v ?

what panels did you use?

Extra sparky, lol.

Pretty vague on the wiring dude..., and I have experience in the field.

Avoid if you care about RFI and EMC.

Pas grand mais cher

find it very confusing , because i notice you keep skipping your video ...... victron is expensive

Viewers should be warned that this is a VERY unsafe installation. Pass on this video and check out someone who knows what they're doing.

NEVER put 2 battery with bms in SERIES, never, you ask for trouble, chance you are going to burn the mosfet and let them stuck open and you will lose ALL protection from the bms, have seen that happen numerous of time, DONT PUT BMS IN SERIES
