System is a 14.8KW system with 2 Powerwall+'s and 1 Powerwall. I have the system setting on self consumption mode. I understand Tesla throttles the system Pre PTO to try and eliminate electricty going back through the grid, but I thought this would only happen once the batteries were full. I am on day 4 of my newly installed system. The behavior just seems erratic. See details below.
Day 1 was super cloudy and rainy. Saw a max of around 6.3KW from the array. To me seemed to operate as it should Powerwalls never got over 30% Charged.
Day 2 was overcast day with rolling clouds. It also seemed to operate as what I would think to be normal. Generated 46.1KWH with a max of 11.9KW. Powerwalls got to 95% Charged.
Day 3 was partly cloudy but overall I think great weather for Solar. I generated 44.4KWH with a max of 10.2KW. I think if the power had somewhere to go, I could have hit 70-80kwh for the day. Powerwalls charged up to 100% before the solar backed down to reduce/eliminate Grid exportation. Again, I would say it acted as it should. Although, we had some heavy energy usage around 4-5pm and the solar never really kicked back in running the powerwalls down to 60% before the sun went down, although we still had strong sun.
Day 4 (Today) as of 1:45pm it has been the perfect day. Clear skys bright sun and high of 70 degrees. I have generated around 30kwh. Max of 9KW. Powerwalls are at 70%.
I have included some pictures below. I just want to make sure this is normal practice and not something wrong with the system.
