Technical FAQs 4

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 much wattage does a solar inverter need?

A good rule of thumb is to multiply the total wattage of your solar panels by 1.25 to account for inefficiencies and potential load spikes. For example, if you have a 5 kW solar system, you would need an inverter rated for at least 6.25 kW. Q: What happens if my inverter is too small for my solar panel system?

Why should you choose a solar inverter size?

Inverters play a vital role in converting the direct current (DC) generated by your solar panels into usable alternating current (AC) for your home. Selecting the proper inverter size ensures that your solar system operates at its full potential, ultimately impacting energy savings and system longevity.

Do I need a solar inverter?

A: An inverter is a device that converts the direct current (DC) generated by your solar panels into alternating current (AC), which is used by most household appliances. You need an inverter to ensure that the electricity produced by your solar power system can be utilized in your home or fed into the electrical grid.
