testing grid tie inverters
As I was preparing to pull my solar off my roof to replace faulty shingles I noticed neither of my 2 solar arrays were producing. Checked breakers and fuses, checked voltage and current, all good except no current. Sunglasses off, the sun is up and no clouds. Recalled something about calling "the Guy" to reset the inverters, no I am "the guy". Turned off the breakers from the panels and called it a day.
Next morning flipped on the breakers and waited for the sun. The current and the sun came up together! I am "the guy"!.
Next day the sun came up but not the inverters. Tried the breaker thing again, tried thinking some more, flipped the breakers back on, still no current.
I still needed to get the panels off for the reroofing says the insurance guy.
So i need to troubleshoot the inverters and panels. I plan to use my golf cart (48 vdc) to test my inverters. My volt meter and a small heater to test the panels. The inverters are enphase m215 grid tie.
Anyone have suggestions for troubleshooting these components the bench?
