    Why does my AIMS Battery Charger turn off when charging from a generator?
    • P
      Paul AguilarAug 1, 2025
      If your AIMS Battery Charger turns off while charging from a generator, it could be due to high AC input voltages from the generator. Try loading the generator down with a heavy load or turn down the generator's output voltage.

    Why is my AIMS Battery Charger supplying a lower charge rate?
    • B
      Beverly BrewerAug 8, 2025
      If the AIMS Battery Charger is supplying a lower charge rate, the charger controls might be improperly set, the AC input voltage might be low, or the battery/AC input connections could be loose. Refer to the section on adjusting the “Charger Rate”, ensure you are using a qualified AC power source, and check all DC/AC connections.

    What to do if sensitive loads turn off during transfer between grid and inverting with AIMS Battery Charger?
    • L
      Lisa ForbesAug 23, 2025
      If sensitive loads turn off temporarily when transferring between grid and inverting on your AIMS Battery Charger, the inverter's low voltage trip voltage may be too low to sustain certain loads. Select a narrow AC voltage in the DIP switch, or install a UPS if possible.
