The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.
To account for power losses assume an 80 percent efficiency. Your solar inverter should have a similar or slightly higher wattage rating than the DC output of your solar panels (which in this case is 4.5 kW). You can size it between 1.15 and 1.5 times larger. The rule of thumb is to size your inverter 1.25 bigger than your solar array.
Depending on where they fall in that band and the size of their solar array, they will likely use a 3, 5, or 10kW inverter. You also need to consider surge watts and voltage drop. Surge watts are the extra power required to start appliances that have motors, such as refrigerators and air conditioners.
Most UK homes need at least a 5 kW inverter. While 3.68 kW is common, larger homes or those with batteries benefit from a 5 kW+ system. What is a solar inverter? A solar inverter converts electricity between “direct current” (DC) and “alternating current” (AC). Electricity produced by solar panels and electricity stored in batteries is DC.
