Dear all,
I have been testing setups with 2 Aliexpress MPPT 500-600W grid tied inverters but for now I have not been successful at sending any electricity to the grid from solar panels. A 12V inverter I use with a 100W panel and a 24V inverter I use with 2 12V 100W panels in series.
The rootcause for such problem is the poor orientation of the panels and not a single day of sun.
Ok, I will wait for a sunny day but meanwhile I have a question. Are you familiar with the startup power of cheap MPPT grid tied inverters?
Even though it is cloudy, I still register a production of 3W (more than the stand-by consumption: 0,7-1,5W); why am I not sending 0,5-1W?
Or question reformulated: Is there any small solar installation owner (<300W) that can tell me what happens in cloudy days? Are you having electricity pushed to the grid during cloudy days? (For bigger installations >1KW it happens).
