Wow impressive. Glad you are safe, nothing burned - learn from it. I have shorted a 16s 48v lifepo4 pack by mistake, and that's not a mistake I plan on ever making again. Safety googles, gloves and insulated tools and environment when working on them at all times. If you are new to this hobby...

Just for those out there that might experience the same issue, it was totally my fault. The ribbon connector for the balance leads was not seated properly, I thought I had checked a ton, double checked all my crimps, correct cable sequence, tested continuity, everything looked absolutely fine...

So, all hypothetical of course. I have a 48v completely off grid system, comprising of a 1000w inverter, 4kw battery and a 150/35 charge controller. Lets say I am pulling 700watts sustained from my inverter. Could I THEORITICALLY plug in a cheap "grid tie" AC inverter from some small solar...

Hi. Working on connecting up a 16s lifepo4 battery and I have gotten to the stage of activating the BMS and can read the values in the app on my phone. The problem I have noticed is that cells 7 8 and sometimes 9 immediately show very out of range and fluctuating values. I think the BMS is...

Thanks for confirming, that's what I thought. Are there any limits (theoretically) on the number of parallel strings in that case assuming they are suitably fused, and do not go outside the limits of the cable size in use? I would like to upgrade slowly by starting with one set and then adding...

Hi all. Newbie here. Some of the only panels I can easily source, due to location, are renogy 12v 100w My question is, they are rated as far as I can tell at Open-Circuit Voltage (Voc) 24.3V Can I reliably hook these panels up as 4s / 1p to a 100v/20a Victron 48v controller? Thanks Chris

Hiya. New guy here also in UK (south). Isn't this completely against the "rules"? As you will be energising circuits that will no longer be covered by the fuse board in your property? Very interested in your progress though as I am in a similar position! I have a constant 400w load and and...
