Why does my Microgreen Inverter Power Pak not turn on?
- C
  Chris MiddletonAug 12, 2025
  The Power Pak might not turn on due to several reasons: * The batteries are not connected, or the connections are loose. Check the batteries and cable connections. Ensure the battery switch, MPPT-battery breaker and MPPT- PV breaker are set to ON. If it still will not turn on, it may be the DC fuse. * Low battery voltage. In this case, charge the battery. An external charging source, such as a car charge, may be required to bring the battery voltage up to the minimum for the Power Pak to function.

What to do if Microgreen Power Pak Inverter charger turns OFF while charging from a generator?
- N
  Nicole NielsenAug 16, 2025
  The charger turns OFF while charging from a generator because of high AC input voltages from the generator. If possible, turn the generator output voltage down. Alternatively load the generator down with a heavy load, for example by turning on a heater.

What to do if Microgreen Power Pak Inverter has no AC output voltage and no indicator lights ON?
- J
  Julie MeadowsAug 20, 2025
  If there is no AC output voltage and no indicator lights ON, the Power Pak may have been manually switched to OFF. Toggle the Power Pak Switch on the front of the Power Pak.

What to do if Microgreen Inverter charger is supplying a low charge rate?
- M
  Marissa ClarkAug 27, 2025
  A low charge rate can be caused by: 1. Improperly set charger controls. Adjust the charging rate using the liner switch to the right of the Battery Type Selector on the front of the Power Pak. 2. Low AC input voltage. Ensure a qualified AC power source is properly connected to the AC input. 3. Loose battery or AC input connections. Check all DC /AC connections.

What to do if Microgreen Power Pak charger is inoperative?
- G
  Gregory MillerAug 31, 2025
  If the charger is inoperative, and the unit will not accept AC power, it is because the AC voltage has dropped out-of- tolerance. Check the AC input source for proper voltage and frequency.

What to do if sensitive loads turn off temporarily when transferring between grid and battery power on Microgreen Power Pak?
- L
  Lisa KochSep 4, 2025
  If sensitive loads turn off temporarily when transferring between grid and battery power, the low voltage trip may be set too low to sustain certain loads. Set DIP SW2 to Position 0 to select a more narrow AC voltage range or install a UPS for sensitive loads.

Why is there unusual noise from my Microgreen Inverter Power Pak?
- L
  Lauren PrinceSep 7, 2025
  Unusual noise from the Power Pak can be caused by applying certain loads, most commonly a hair drier. Certain types of loads can cause internal components to rattle or vibrate. This will not harm the Power Pak or connected devices. The noise should stop when the load is reduced, for example by unplugging the hair drier.
