Technical FAQs 4

What happens if a solar inverter overloads?

An overload in a solar inverter occurs when the power input from the solar panels exceeds the inverter’s capacity to handle or convert it safely into output power. This condition can stress the inverter's components, such as capacitors and cooling systems, beyond their operational limits.

How many kW can a PV inverter output?

Export to Grid: Up to 4kW can be sent back to the grid because of the export limit. This means: The inverter can handle this 5kW AC output perfectly. However, the PV array is generating 10kW, so we have:

What happens if a solar inverter is not fully charged?

If your batteries were not fully charged, the excess solar energy would be sent to the battery storage. Here’s how it would work in that scenario: House Load: The inverter first meets the 1kW house load. Export to Grid: Up to 4kW can be exported to the grid, if allowed.

How does a PV inverter reduce power output?

By reducing the current, it effectively reduces the power output. Maximum Power Point Tracking (MPPT): Normally, the inverter uses MPPT to maximise the power output from your PV array. During curtailment, the MPPT algorithm adjusts to a point where the power output is reduced to match the inverter’s capacity.
