    The Solar Inverter is applied with Maximum Power Point Tracking (MPPT) technology to harvest the maximum amount of energy from the solar panel. Measurement must be taken to ensure that the maximum open circuit voltage of 500 VDC is never exceeded. Please note that the maximum open-circuit voltage will occur at the lowest temperatures anticipated.

  • Page 11: Monitoring The Inverter

    Using an AC voltmeter, measure the AC open circuit utility voltage between L and N. Ensure this voltage is at approximately nominal value expected for the local utility company. Check battery voltage Ensure that battery voltage is at approximately nominal value expected for inverter(48Vdc). The line breaker and battery breaker are correctly rated Before switching on the power, check all feeders and connections again.
