Important note: The boiler is not able to charge a battery. The boiler is only connected to the battery as an electrical consumer via the battery cable. The battery is usually charged via a photovoltaic module, an alternator or a small wind turbine. The energy stored in the battery or excess energy can be stored in the boiler as heat.
- The 10 liter boiler can be charged with a 12V or 24V battery system.
- The 30 liter boiler can easily be charged with a 24V battery. If this were heated with a 12V battery, the heating times would be very long.
- The 80 liter boiler can be charged via the 24V battery. Here, however, the relatively long heating-up times must be considered. Depending on the application and water consumption, this can still be useful.
