Northern Plains Power Technologies. Results from modeling and testing of commercially available inverters showed that load rejection overvoltage was not as big of a risk as the utilities feared. I also lowered the max charge rate to 10% (inverter) and 20% (charge controller) -- these had been at their default of 100%. Features Reinforced isolated inverter suited for 200-V to 690-V AC drives rated up to 10 kW. Therefore, when working with inverters or inverter components, ESD protective measures should be observed. Loose control wiring causes erratic frequency inverter performance, resulting in unpredictable speed fluctuations or the inability to control the frequency converter. Hopefully, with more data the PV industry will be able to prove the need and standardize on the best method to protect utility lines from TOV, or disprove the need for effective grounding on PV. Siemens Micromaster 420 Faults and Alarms. Overvoltage at the input. In principle, the PV inverter itself does not generate voltage. Since the PV inverter has little to no rotational inertia and no winding impedance, some  inverter companies use rated voltage and the measured maximum output current during a fault condition to derive X1 (Vrated/Irated).
