Hi guys I am having a major issue...I installed 40- 430 watt solar panels on my roof and using a Sol15k inverter... panels are wired 6S6P (2 strings) and the last string 8S8P.
It seems that the highest I have seen the production is about 4.8kw on a sunny day and at times when the load is higher around 6kw I am having to pull from the grid or battery to make up the short fall. Any idea what could be causing the low production...panels were purchased new at the time of installation however I can't say if the supplier sold me a bad stock of defective mods. Any idea on testing to isolate the issues?
Thanks in advance
