That is interesting about the Enphase system staying up. From what I've read, there's a push to make newer grid-tie solar inverters add robustness to the grid in cases of significant distributed generation (lots of residential solar) by being able to ride-through power fluctuations so that...

Thank you @BentleyJ, that was what I expecting/hoping. Encouraging to hear from someone with experience. I'd like to understand how the Anti-Islanding function works better in case of a grid failure and two inverters suppling the same panel. I guess in the scenario when the grid is not there...

How is your export to the grid metered by your utility? We have 2 meters, one is for the service entrance (billing) and one is for the solar system only. We get charged for the non-negative kWh's on the billing meter and paid for the metered "usage" on the solar meter. I think I want both my...

Thanks. I guess NEM stands for Net Energy Metering? My original agreement states I'm allowed up to 15kW system. I have spoken to my utility, and they tell me they will honor my original tariff under that agreement from 2015, and still allow me to produce up to 15kW.

Hi, I've done some searching and am struggling to find relevant answers. I have an existing 6kW grid tie system using 22 LG panels and a 6kW Fronius Primo inverter. I recently acquired a whole additional 3kW system (8 Astroenergy 405W panels, 1 3.6kW Solis inverter), that someone was selling...
