We hooked up 4 EG4 6500 inverters, along with 8 PV strings and 2 EG4 battery racks. 3 of the inverters were working, along with the batteries, PV input, and AC output. When we turned on the last inverter, we heard a pop and then everything shut down.
I have been trying to test the other inverters individually and as pairs. Whenever we do, we hear a clicking sound from the batteries and then the batteries get a fault-short circuit output protection. The inverters do not turn on. If PV is turned on, the inverter stand by mode comes on with a bP error.
Tech support has not been very helpful at Signature Solar. They will let us send in all 4 inverters (and a PV switch that doesn't work), but we have to pay the shipping because we live in Hawaii (this was not mentioned during the sales process or on the website). Is there any more troubleshooting we can do before paying the cost of shipping?
Thanks,
Carrie
