associated with high penetration levels of inverter connected PV generation. 2 Test setup Table 1 lists the PV inverters that were tested at the PNDC. Some of the inverters can have G83 or G59 settings activated as required. However, the table shows the active settings during testing. Phases PV Inverter Maximum AC Power Rating Active settings

HOW TO TEST YOUR SYTEM

Remember, if the battery is full it may not be accepting current, resulting in a low reading. Expect a current of around 3.5-4A in good sunshine, with an empty battery. TO TEST THE REGULATOR Measure the operating current as described previously. Re-connect the solar panel directly to the battery without the regulator.
