    Help identify BMS

    I purchased a 24v 300ah battery from Alibaba Qishou technology and wasn't sure if they screwed up or not. On a sticker label on the battery is shows JBD150A (7680WH) and in the APP BMS model is AP21S001-V11GB. The sticker on the battery worries me because it looks like 150A and I cant really...

    Battery capacity tester

    I'm not too keen on leaving this run overnight, do you think it would matter if I run it all day, stop it at night and resume in the morning? Im also thinking on getting the one that has multiple boards so it can go up to 600w.

    Battery capacity tester

    I would use the inverter and shunt I currently have but all of it is at my camp which is not accessible during winter. I ordered myself a cheap 24v inverter and shunt. https://www.amazon.ca/gp/product/B08TR3JZ4W/ref=ox_sc_act_title_1?smid=A505H0U4TGVUQ&th=1...

    Help with selecting charger

    I purchased a 24v 300ah Lifepo4 battery and it should be in in a couple of weeks. I was wondering if there was any recommendation on a charger that is about 50a to 60a, unless this is not a good idea.

    Going to Lifepo4

    No my system is currently 24v 420aH. My only thoughts was in the event I want to separate my system I could go back to 2x 12v systems, one for my outdoor power needs as well as my DC fridge in the garage and the other for the RV. But thinking this out more that doesnt make much sense so I should...

    Going to Lifepo4

    My system at camp is currently 24v 420aH FLA batteries and I want to move to LiFePO4 next year but I am stuck in selecting where and what to purchase. I would like to stick to 12v in the event I change the batteries or go back to 12v inverter, I can reuse the batteries or sell them easily, 24v...

    Inverter overload - strange problem

    If the generator is on straight to the camp and I turn the ac on it works. If it’s on feeding the inverter in bypass/charge mode, that’s when the inverter trips. I tired to turn off eco mode too, same results. The generator doesn’t trip or anything, it’s the inverter that goes into overload for...

    Inverter overload - strange problem

    I have an Aims 24v 3000w inverter charger with a 420ah battery bank. Everything works great either in inverter mode or when the inverter is in charge/bypass mode with my Yamaha 3000efi inverter generator. When I use my air conditioning unit (it has a hard start kit) in inverter mode the...

    Building my first system

    ok I see what you mean. I really don't want to mess with the existing rv electrical and I will never be somewhere that I can get electricity as we park and leave our rv on our lot and don't have electricity available to us. This is why I would like to be able to plug the existing shore cord to...

    Building my first system

    Sorry I am not following what you mean? I am connecting the generator to the inverter AC input and then the inverter ac output to the camper shore power cord. Is that correct?

    Building my first system

    Took a quick look at the Yamaha generator and I believe this means that it does have breaker protection Overload indicator light The overload indicator light 1 comes on when an overload of a connected electrical device is detected, the inverter control unit overheats, or the AC output voltage...

    Building my first system

    First of all thank you again for all the help Jim. I took the time to read the manuals and draw what my setup will look like from what I understand. Let me know what you think and if there should be changes. Here are a few of my questions i currently have. Why is the manual asking for a 300a...

    Building my first system

    I can for sure crimp my own if I need to. Do you have any recommendation for hydraulic crimpers and ends? Looking at amazon I can see many of them that crimp in a hexagon shape, are those correct?

    Building my first system

    Ok I totally missed the info in the inverter manual about fuse, breaker and wire size, thank you for pointing me in the right direction. I want to be able to connect my trailer plug to the inverter and my Yamaha EF3000 generator to the inverter to bypass when needed, is this possible? I would...

    Building my first system

    Thanks for the reply Jim. The batteries are 12v and I will be connecting them in parallel. As for the Max PV input, I guess this will allow me to add a second 315w solar panel at a future date if needed, staying within the 780W. I am looking at the wire size calculator, what is the length...
