Your inverter size should match your solar array's capacity, not your electricity bill. This means your inverter doesn't need to power your entire home—it just converts whatever your panels generate. Let's say you have a 6kW solar array (twenty 300-watt panels).
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.
Choose an inverter that has a surge watt rating equal to or greater than this value. As for voltage drop, check the wire length between your solar panels and the batteries. If the wire length is long, you may need to choose a lower voltage system (12V, 24V, or 48V) to minimize voltage drop.
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.
