You will definetely do better when the sun shine. I had my account down from R3000.00 to R7.23 and another time to R15.00. Since installation 2.5 years ago my account has never been more than R100.00 I run pool pump, pressure pumos X 2, borehole pump and then still all the normal household appliances. Mine consist of 2 x KW Luxpower inverters, 2 x 12 Panel 430W JA Strings and 4X LiPe 100KW batteries. When the sunshine you make hay and when it rain you use it sparingly. Pieter
