How do I choose a solar inverter?
When designing a solar installation, and selecting the inverter, we must consider how much DC power will be produced by the solar array and how much AC power the inverter is able to output (its power rating).
What is a solar power inverter?
A solar power inverter is an essential element of a photovoltaic system that makes electricity produced by solar panels usable in the home. It is responsible for converting the direct current (DC) output produced by solar panels into alternating current (AC) that can be used by household appliances and can be fed back into the electrical grid.
How much wattage should a solar inverter be?
You would need to purchase an inverter that matches the output of your solar array, so if you have a 6000W (6kW) system, your inverter would need to a rated at 6000W. You also need to consider the two different wattages involved here as there is a continuous and surge voltage.
Should I use a 5 kW inverter with a 6.6 kW solar system?
For example, a 6.6 kW solar system is often paired with a 5 kW inverter. Because the panels are only rarely generating at their full rated capacity, this can be a good way to get the best value from the inverter and often makes good economic sense.
