Photovoltaic kits for the home without storage, built for daytime self-consumption: SMA at 4.72 kWp with a 3.68 kW single-phase inverter, FoxESS at 7.67 kWp on a 6 kW three-phase inverter, SolarEdge at 9.44 kWp with module optimisers and an 8 kW inverter, GoodWe at 11.8 kWp with a 10 kW string inverter.
Without a battery the system only covers consumption while it is producing: the financial return depends on how much energy you use during the day, typically 30 to 40% if you do not shift appliance use. SolarEdge optimisers earn their place on roofs with shading or differing orientations.
They stay ready for more: many of these inverters accept a battery later.
