When the 12 V /Max 30 amp Victron Blue Smart IP22 charger is connected to the battery busbars and the AC 220V input is turned off, there will be a very low energy consumption due to the internal resistance of the charger. How much this consumption can drain our battery. Can you give this value in watt hours?
The value in watt hours will depend on how long you leave the charger connected.
The dc input current to the charger will be very low - of the order of 1/1000A (1mA). This can usually be ignored. If the current is 1mA, the voltage is 12v, and you leave the charger connected for 8,750hours (~1 year), the total energy would be 105 Watt hours.
Thank you very much indeed
