[RE-wrenches] Inverter ratings exceeding 25kw fir battery backup

[Lloyd Hoffstatter]

The same in NY we had to change existing equipment to stay within the 25k AC net metering limit.

Why is there a need for more than 25KW for residential please? Just curious. In Nevada, 25KW is way into commercial.

Greetings wrenches,
In Pacific Power territory we are coming up against roadblocks with regards to whole house battery backup systems with inverter ratings higher than 25kw. Even when the generation capacity is below the 25kw residential limit, net metering applications are being rejected based on the inverter rating.. The inverter rating in these cases is sized to handle the customer's existing loads and will never export more than the 25kw limit dictated by Oregon PUC.  I am drafting a letter to Energy Trust, the state, etc. But am curious if anyone else gas had this problem or come up with a solution. I would appreciate to hear any experiences or similar interactions with PGE or PPL or even how this has worked in other jurisdictions, states, etc. Any input or support is greatly appreciated.
