Technical FAQs 4

Do I need a solar inverter?

For most home and portable PV systems, you will only need one inverter if you are using either a string inverter or power optimizers for the solar array; if you use micro-inverters, you won’t require a standalone inverter all as they convert DC to AC at the panel.

How big should a solar inverter be?

Generally, it's recommended to size the inverter to 80-100% of the DC system's rated capacity. Before determine the inverter size, the most important thing is to calculate your average daily power consumption (kWh) and calculate your solar panel array size to match your power consumption. You could follow our to make this estimation.

How many inverters do you need for a 12 kW solar system?

Inverter: one or two inverters of a combined 10 kW–15 kW A 12 kW solar installation in a farm near Berlin utilized a 10 kW inverter with excellent results—saving a couple of hundred dollars on initial cost and still registering peak output. 3. Equate Load Requirements, Not Panel Watts It's not solely about sunlight—actual usage matters, too.

What is a recommended inverter power range?

By inputting your panel's rated power and number of panels, the calculator produces a recommended inverter power range that aligns with 80-100% of your system’s total DC capacity. This approach ensures that your inverter is neither under-sized—risking energy losses and performance issues—nor over-sized, which can lead to unnecessary costs.
