Hello everyone. I am seriously starting to consider going completely off the grid and terminating our Eskom Supply point on the farm, just the monthly connection fee i.e. R5000 can make a good dent in financing a solar system. Current consumption is around 70Kwh a day, peak loads around 12kw, but would like a bit of an oversized system. This is where I need the opinion of you guys. We are currently on a three-phase system but there is no three-phase equipment running anymore, would it be worthwhile switching to single-phase? I have a lot of trees around the house, but there is clear and secure area where I would get full unobstructed sun every day. But it’s around 70m away from the farm’s DB board, could that potentially be an issue? Would a system like the following be adequate? 2x12kw Inverters (if going single phase) and for redundancy 40kwh of battery storage (maybe a generator for rainy days) 25-30kWp PV array Thank you.
