Why is my Victron energy Multiplus alarm LED flashing?
- D
  Denise GreerJul 28, 2025
  The alarm LED might be flashing due to several reasons: * The DC input voltage is low: Charge the battery or check the battery connections. * The ambient temperature is too high: Place the inverter in a cool and well-ventilated room, or reduce the load. * The load on the inverter is higher than the nominal load: Reduce the load. * Voltage ripple on the DC input exceeds 1.25Vrms: Check the battery cables and terminals and the battery capacity; increase capacity if necessary. * Low battery voltage and excessive load: Charge the batteries, reduce the load, install batteries with a higher capacity, and use shorter/thicker battery cables.

What to do if my Victron energy Inverter battery is not being charged fully?
- S
  Sonya MartinAug 5, 2025
  If the battery is not being charged fully, consider the following possible causes: * Incorrect charging current: Set the charging current at between 0.1 and 0.2x battery capacity. * A defective battery connection: Check the battery terminals. * The absorption voltage has been set to an incorrect value: Adjust the absorption voltage to the correct value. * The float voltage has been set to an incorrect value: Adjust the float voltage to the correct value. * The internal DC fuse is defective: Inverter is damaged.

What causes a Victron energy Multiplus Inverter battery to overcharge?
- C
  crystalsmithAug 11, 2025
  A battery can be overcharged due to: * The absorption voltage being set incorrectly: Adjust the absorption voltage to the correct value. * The float voltage being set incorrectly: Adjust the float voltage to the correct value. * A defective battery: Replace the battery. * The battery being too small: Reduce the charging current or use a battery with a higher capacity. * The battery being too hot: Connect a temperature sensor.

Why does Victron energy Multiplus Inverter battery charge current drops to 0 when the absorption voltage is reached?
- A
  Alan McmillanAug 20, 2025
  The battery charge current may drop to 0 when the absorption voltage is reached due to: * Battery overtemperature (> 50°C): Allow battery to cool down, place battery in a cool environment and check for shorted cells. * Battery temperature sensor faulty: Unplug battery temperature sensor from the MultiPlus. Reset the MultiPlus by switching it off, then wait for 4 seconds and switch it on again. If the MultiPlus now charges normally, the battery temperature sensor is faulty and needs to be replaced.
