Sean123 Posted March 25 Share Posted March 25 Hi, I have installed 2 x 12kVa 3 phase Deye inverters connected in parallel. Even though I have ample solar genration, it still draws power from the grid. Load first is enabled. I would really appreciate any advice on minimising the grid usage. Thank you.

Jakac Posted March 25 Share Posted March 25 Looks like the solar power is not enough for both charging the battery and house loads. You can reduce the loads to see if it continues to draw from the grid CobusK and Thunderdolt 2 Quote Link to comment Share on other sites More sharing options...

Sean123 Posted April 4 Author Share Posted April 4 We finally found the problem. It seems like the inverter draws from the grid on the smartload - this has something to do with reactive power. I took the geysers off the smartload and the system is working perfectly. Quote Link to comment Share on other sites More sharing options...
