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. 👍

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

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.

[valentino_govoni_official]

this is what im worried about if i use AGM batteries, will they valance?

[cleversolarpower]

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.

[howardescoffery]

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.

[pisoiorfan]

Electroboom would definitely go for the largest sparks.

[panospapadimitriou]

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!!!

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?

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, 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!

[enigmascape]

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.

[darryllillian]

Understanding 12 V I made the typical mistake of buying some 12 V batteries so I have four 100 amp hour 12 V that I would love to use in a system while I save up to get either a 24 V or 48 V battery bank.can I do two in series, and then two banks in parallel to get the use of all four batteries and make it a 24 V system. I am learning, but still very much a solar novice.

[scoutmaster-s]

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

[Firephosure]

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 ?

[junkerzn]

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.

Just got my 2nd battery to go with my Victron controller and next to order a inverter-almost there
