Has anyone successfully installed two EP900 systems in the California IOU areas (PG&E,SDGE,SCE)? I am currently going through the interconnection application with PG&E, and have been stuck and the equipment submittal process for two months now. In California, under CEC regulations, any inverter with >10KW AC and >10KWH capacity needs one of three options:
- UL 1741 CRD-PCS or UL 3141 certification,
- Installation of a Net Generation Output Meter (NGOM) ( I have an existing NEM 2.0 8KW Enphase array, the NGOM would be placed to measure this arrays output).
- A Non Export Relay installed (but all the meters listed on PG&E froms G2 & G5 are utility grade 4160V or higher meant for distribution and transmission voltages).
I believe I have exhausted my arguments for cases 1 & 3, and am resigned that installing a NGOM may be my only option, I would just like confirmation before I do that this is the only or correct path.
