January 24, 20233 yr Current setup is a 3KW (Kodak) inverter, 2.8kw (Pylon) battery with 6x 340w pv panels in place (1 year old) It runs all essentials save for the fridge. We want to upgrade this to also run the fridge LG double door (1 year old - latest tech- seems to require under 300w in stable state) and microwave (1000w unit). The inverter runs at best at 30% capacity currently with the coffee machine in the home office on, else, at under 15%. I have ordered another battery already. The first question is whether to expand the solar array or replace the panels with 540w ones. What would be more economical? Secondly to how much capacity should we expand the panels? I live on the West Coast. My roof/panels face north-east. House was built in 2016 with all available power saving devices available, (gas water heater for kitchen and gas stove, solar geyser for showers, led lights, etc) save for solar. Power consumption from the grid was always around R450 per month. It has now fallen with solar to around R200 per month. Just 2 people in the house. Any advice shall be appreciated.
