Received an Error Message: R660 String Short Circuit Current is too large for inverter

Error Message Received:

Typical Causation:

This error is usually caused by a solar module string's short circuit current (Isc) under high irradiance exceeds the maximum input current for the solar inverter.

An Example:

Consider the following example with a solar inverter being utilized with a solar module that has an excessively high wattage output:

Explanation

In this case, the error occurred because the solar module’s output was 17.8 amps after applying a high-temperature correction. The selected inverter has a maximum input capacity of 15 amps.

Potential Solution

As a solution, a different solar module, inverter pairing, or stringing can be utilized, and the SolarAPP+ inputs to be adjusted accordingly.
