Product Description

SRNE SAA 1250 3-in-1 50A MPPT & DC-DC Charge Controller (12V/24V)

3-in-1 Campervan & Off-Grid Battery Management Hub UK

The SRNE SAA 1250 (SAA1250) is an all-in-one 3-in-1 battery charging unit designed specifically for campervans, motorhomes, marine vessels, and off-grid builds. Combining a high-efficiency 50A MPPT solar charge controller, a 60A DC-DC alternator charger, and a 50A AC mains shore-power charger into a single compact housing, it eliminates the need for three separate devices. Supporting both 12V and 24V leisure battery setups (including LiFePO4 Lithium), the SAA 1250 coordinates multiple charging sources automatically to ensure your leisure batteries stay fully charged wherever you are.

Why choose the SRNE SAA 1250 3-in-1 Charge Controller?
