Solar Sign-Off For Micro-Inverters

[matt.leung]

I work for a company installing solar panels. The company has recently installed micro-inverters on an install.

When using micro-inverters there is very little DC to test as the inverters are sealed units with only AC outputting.... What do you normally mark down on the DC paper-work side?

many thanks

I would usually just have the panel sheet filled out - all other DC string tests are N/A..........

n.b. Solar Edge are even harder - the modules below the panels are optimisers, not inverters; so ther si still DC on the lines; but only when the inverter "switches them on" - so you cannot test Voc or Isc for the strings - the only option is to interrogate the inverter with a lappie, and note its details of each panel

I've PMed you a copy of one of my test sheets - the sheet just doesn't suite micro-inveters
