[QUOTE="karlboldy0, post: 529128, member: 35192"] Hi there, We have an existing 1kw solar setup which was on the house from new by the developers. Pretty useful setup but better than nothing. Recently just had installed a 5kw (12x 410watt) panels, with 3.3kw battery and EV charger. The setup is growatt, with the team being very professional when they install it. Monitoring both systems, we seem to hit a wall at 4kw generation and can’t get past it. The roof faces south and gets direct sunlight with no trees or shadows. When I compare. It’s side by side there is a 10% difference in the generation capability of the existing install over the new one. Is this normal? Could it be the recent heat? Just keen to make sure we are getting all the bang for our buck. [/QUOTE]
