Arguments between the MPPT, the BMS and the Inverter have ensued.

One cell, in particular runs, and when the MPPT hits it's shut off voltage, the voltage of the inverter fluctuates wildly, causing issues on the AC side.

Turning the high voltage cut off on the mppt down (28.4-27.2) helps the second issue, but the first issue I'm not sure if I need active balancing, and then whether I need 1 or 5 amps of it.

I'm a #vanlifer, and I live in my #CamperVan that I built entirely from scratch myself. I've got a full #solar system, 21 gallons of water storage, diesel heater, a fridge, kitchen, bed, all stuffed into a tiny Grand Caravan. I'm currently in the #losangeles area and looking to make connections with other cool weirdos. But, being in a van the location could easily change, although I don't plan on going anywhere for a while.

#China says #wind and #solar #energy capacity exceeds #thermal for first time
"Trump pulled #US, e world’s 2nd-largest #polluter, out of Paris #climate accord while pledging vast expansion in #fossilfuel exploitation.. 2024, #PRC added record 357GW of wind & solar, 10 times US’s additions. It met a 2030 target to install 1,200 GW of solar & wind cc almost six years early.. China also began #construction on 94.5 GW of #coalpower projects in 2024, 93% of the global total"
