Went to charge the batteries, and the green light didn't come on. Um.
Checked, and the GFCI on the BC-20 had tripped. Reset, and tried again. Tripped again.
Fine, so I ordered a PFC-20 with the "buck enhancement"; I guess that will leave only batteries.
I'm going to replace the Curtis 1221C controller with a Zilla Z1K-LV 72-156v 1000a controller. The manual suggests liquid cooling, so I'm going to be doing some modifications to accomodate that.
The point of this?
The Curtis 1221C supports up to 120v. The BC-20 charger supports up to 108v without a line converter, and 120v with it. However, I'm looking at Evercel NiZn batteries as an advanced chemistry to replace the existing Trojan 105s, and to keep approximately the same kWh capacity, I need 13 of the 12v M100s, for 156v. So this is step one in the grand plan.
