Hello! First post and relatively new to DIY solar. I've installed solar in the field but all grid-tied. Off grid battery systems I have only every done small >1 kW. So this is new territory for me.
Through a job, I have acquired a new 24-125-13 FLA forklift battery and 6 kW of PV. This is for my own personal off-grid cabin in the woods. It will replace my 24 volt 210 AH system, currently fed by 420 watts of PV.
My question is about taking care of this big expensive battery. I'm concerned that I don't have enough solar to charge it the way this battery would normally be charged in the wild: high current for a long time. I'm no battery expert, but I understand that it should be charged at or above 0.1C, which is more than 100 amps. In the best sun conditions I have, I'm not confident the array can supply what is needed for long enough. I haven't bought (or built) a charge controller yet, so I am feeling this out and looking forward to everyone's advice.
Thanks,
Will
