Advanced Smart Solar Regulator for Off-Grid, Caravan & Marine Power Systems
Maximise Solar Efficiency with MPPT Technology
The Powerhouse 12/24V MPPT Solar Charge Controller (20A) delivers up to 20% more charging efficiency compared to traditional PWM regulators. Using Maximum Power Point Tracking (MPPT) circuitry, it intelligently optimizes voltage and current from your panels, ensuring you get the most energy from your solar array — perfect for new installations or boosting existing solar systems.
Designed for permanent solar setups using lead acid, gel, or lithium batteries, this compact controller automatically detects 12V or 24V systems and provides clear feedback through its LCD display and status LEDs. Ideal for caravans, off-grid cabins, pumping stations, marine systems, and remote lighting applications.
