Sunsynk 12kw x 2 3 phase parallel hybrid system Fault


Hoosen

Question

Hi to all. I need some advice please. I have a Sunsynk 12kw x 2 3 phase parallel hybrid system with 40 Ja Solar 540w panels and a freedom won battery installed in October 2021. Has been running well until recently when I noticed that production drops randomly to around half of what is expected for that time of day. As an example, last week on a clear day it went suddenly from 13000w to 6001W. Around 10 minutes later it went back up. Todays graph looks even worse with multiple ups and downs. his was today. Everytime consumption goes up production drops significantly. We had full sun today and not a cloud in sight. I checked the inverters. Internal fans were working and the units were not hot. Any thoughts?Solar panels were cleaned 5 days prior and firmware was reinstalled as per advice of my installer. Any ideas as to what else might be at fault?

If you did a firmware update I would ask for it to be rolled back, second to that the panels were cleaned. I would check the connections as I am not sure how they were cleaned but maybe water ingress.

 

Also look to see if there is water build up in the bottom of the PV frames, again not sure how there where cleaned but water ingress in a panel and perhaps on a bus bar with in the panel.

Also if it's a tiled roof and from cleaning someone standing on a tile and perhaps sqaushing the PV cables caused a cross sectional area of the cable to reduce.

 

Shot in the dark but that is what came to mind.
