So, instead of a an actually charger, is it feasible to charge new (LFP) batteries using an inverters SCC. The inverter wouldn't be under load or an any AC/DC out. Just PV in & the battery/batteries hooked up.
I'm looking to do my best set-up for (20) Q-cell 405w panels to a Growatt 12kW inverter. Being a newb to all this & still learning, I'd sooner swallow pride than make any grave mistakes.
So my question..... Whats my way to hook all this together? How many in series/parallel for how many strings...
Just starting out, purchasing an off-grid w/ small system. Plans are to see what I can ran, then possibly be upgraded Though, till then then reading & lurking to improve my own knowledge on solar.
