FX Adjustments per Power Factor

Post by Woody »

I learned the hard way a long time ago that the Trace inverters measured in RMS and did not adjust the charging parameters (net loading) according to actual power factor conditions. When you have a genset that is close to the peak power demands (consumer load + battery charging) and the power factor drops off due to strange loads (rural customers), the Trace does not 'see' the real power demand and maintains its charging level. This can result in overloading the genset or tripping its breaker. Does the new FX adjust operating parameters for power factor? Of course the best solution is a bigger genset. This could be an important issue for larger inverter packages for rural electrification schemes.

The FX inverter measures the in-phase component of input current and you are correct that this can lead to tripped breakers when the power factor of the loads is low. I intend to correct this problem in the next software revision.
