Interesting...Rainbow Power dont have anything in the way of lightning rods saying trees usually take care of the problem☺...I am thinking the old phone line is the problem and digging it up could help.
A new inverter/charger will cost around $1500 which I can manage but blows all hope of a new 120 mm.
Probably reconfigure everything and up the system to 24 volts...got the battery side worked out but not sure with the panels..must be much the same...parrallel series..that sort of thing.
