Inverter power becomes smaller

4 FAQs about [Inverter power becomes smaller]

What does oversizing a solar inverter mean?

Oversizing your solar system generally means that your solar inverter is oversized for the amount of solar panels and energy output you currently have. An example of this would be if you have 4kW of solar panels but a 5kW solar inverter. Why would I oversize my solar inverter?

How does a solar inverter affect efficiency?

The efficiency of the inverter drives the efficiency of a solar panel system because inverters convert Direct Current (DC) (as produced by the solar panels), into Alternating Current (AC) (as used by the electric grid). This leads many to wonder what effect over-sizing or under-sizing an inverter will have on overall system efficiency.

Should I undersize my solar inverter?

Now that we are on the same page, let’s talk about undersizing your inverter! Undersizing is not only common but usually recommended. When you hear of a 6.6kW solar system, this will mean that there are 6600W of solar panels installed with a 5kW inverter.

Should I buy a larger solar inverter?

Maximise STCs: Purchasing a larger inverter might negate the savings you will receive on your STCs. A smaller inverter with maximised solar panels will attract a greater return when claiming the STCs. More efficient system: While a solar panel may be rated for 400W of solar production, the panels will not produce this 100% during daylight hours.
