[QUOTE="archer327, post: 539321, member: 36058"] I was wondering if anyone could help me understand what happened with my system after a mistake has been made. The installer was supposed to put 5.6kW solar panel system with a 5.12kW inverter and a 5kW battery which they did but by mistake they installed a 8kW inverter instead. This fact came to light only two months after installation. I am not planning to add more panels. Am I disadvantaged by this mistake and should I demand a replacement of the inverter for 5kW? I’ve read that, although oversized inverter may have a longer life span due to less stress, it might actually produce less electricity compared to the matching or undersized inverter as it ramps up slower at periods of low solar activity (mornings, evenings, winter, autumn).
