Why do Dave's new 370W LG solar panels use lower rated 295W Enphase microinverters?
What gives?
Inverter clipping, solar panel overrating, DC/AC ratio, solar irradiance, and microinverter underrating explained.
And a look at data from Dave's old 3kW system to predict how many days a year the new 5kW system will clip.
