I got my 18kpv, and I don't have a question so much as a quick thanks. @GRV0423 has been helping me last night and today. Got this setup perfect. Once i get all my panels up and orientated, I won't be using much grid power. Tip of the hat to @GRV0423 for the excellent support.

I just ordered a eg4 18kpv and 30kwh of eg4 server rack batteries. I see the eg4 18kpv has two inputs for the batteries. Do I just connect one to the bus bar on the case, or two?

I just got my new eg4 18kpv and am trying to setup the dongle. It asks for a customer or installer code. Anyone know where I can find that?

Looking for a bit of advice. I live in a suburban area and have a ground mount system. I have 20 400w panels. In midday they produce wildly well. In the mornings and afternoons, not so much. Some of each string is shaded by tree or home. Would optimizers on each panel help, do you think? And...
