I may be losing my mind, but I'm convinced that since changing from a Solis 5kW inverter to a 5g 6kW one, my system performance has gone to crap.
Generation is lower on average, particularly at low times like early morning and late evening.
Mid morning on a poor day I'd normally be pulling 7-800w but these days I might only get half that. On a good day I'd still be generating 5-600w at 9pm, yesterday was the hottest day of the year and I was basically flat lined from 8pm.
I know that hotter weather affects panel efficiency but this was not normal.
Is there any possible explanation for this? Even today, its overcast and raining intermittently. Based on the past few year's experience I'd expect to be generating about 700w even in the rain. Instead it's about 300w.
