Inherited an old 12V lead acid system and ended up changing the batteries/inverter/solar panel controller. Still 12V, but now with four 206ah SOK LiFePO4 wired in parallel to a DC fuse box for the lighting, water heater and water pump; a victron mppt; and a 3000w inverter (pure sine wave) for...
Hello! I'm replacing lead acid batteries in a older system, using four SOK 12V 206Ah LiFePO4 batteries (in parallel). I have a Outback FlexMax controller and am wondering how to change the settings and what they should be. I inherited the system with the property and the lead acid batteries are...
Can I go with the standard parallel configuration (pos to pos, neg to neg) or do I need to do a more balanced load configuration?
I keep seeing people oscillate between how the connect/disconnect terminals. My understanding has always been disconnect negative, then positive, reconnect positive...
I have very limited internet, as I live remotely off-grid. For some reason, this forum isn't heavy on the bandwidth. Videos or pdfs/long documents are difficult.
There's Outback forums? Would you mind sending me a link? I do have a manual for the outback, but it's geared more towards pros than beginners. It lists snoozing as not enough current to charge.
Originally, I changed up the absorption time (1hr), absorption to 14.4v and float to 13.6v for the...
Sure. Based on the diagram, I was asking if the standard (diagonally) was good enough for the SOK 206ah due to their BMS or if something like the halfway would be better.
Thank you. Outback was zero help.
I'm guessing the temperature sensor is already disabled since there's nothing plugged in? (2nd telephone plug from the left)
Thank you for your reply. The solar panels are grounded to their own rod.
I've no idea the max draw. I am working on upgrading the system that came with the house as I live remotely and supplies/services are not readily available, so I upgraded the batteries based on what had been there. On the...
Oh and if I'm upgrading the wire to the DC fuse box, there's a T class fuse (110a) which I'm guessing I'll be switching out as well to 250a (195x1.25)?
Hi! I replaced old lead batteries yesterday in my system with new lithium batteries and now my controller is snoozing, indicating there's not enough current to charge. Getting in 59v, but no amp. I had to disconnect and reconnect the wiring for the PV array from their breaker box to the...
