Truma SDC25 Dual-Battery Solar Charge Controller

The Truma SDC25 is a dual-battery solar charge controller for caravans and motorhomes, designed to charge two separate battery banks from a single solar array. With a settable charge-current distribution between the two connections, it's ideal for vehicles running both a leisure (supply) battery and a second battery such as a starter or auxiliary bank.

Why choose the SDC25

• Charges two batteries — independently manages a supply battery and a second bank.
• Adjustable current split — set how charge is distributed between the two connections.
• Wide battery compatibility — suitable for liquid, gel and AGM batteries.
• Built for continuous use — designed for continuous operation and parallel mode.
• Temperature-aware charging — works with an external temperature sensor on the supply battery for safer, more accurate charging.

Specification
