MPPT Solar Charge Controller | 12V/24V Auto | 30A 40A 60A 100A | Dual USB | LCD Display | Battery Regulator with Load

Smarter Solar Charging. Protect Your Battery. Maximise Every Watt.

Whether you’re running an off-grid cabin, a campervan, a narrowboat or a garden solar setup, this MPPT solar charge controller keeps your battery bank healthy and your system running efficiently. MPPT (Maximum Power Point Tracking) technology extracts more usable power from your solar panels than standard PWM controllers — especially in low-light or variable conditions. The clear LCD display shows voltage, current and charge status at a glance, and dual USB output lets you charge devices directly from the controller. Available in 30A, 40A, 60A and 100A ratings to suit systems from small domestic setups to larger off-grid installations.

Why You'll Love It

• MPPT technology — Maximises energy harvest from your solar panels; more efficient than PWM in variable light conditions.
• 12V/24V auto-detection — Automatically identifies your system voltage; no manual configuration needed.
• 30A to 100A options — Choose the rating that matches your panel array; suitable for small domestic to large off-grid systems.
• LCD display — Shows voltage, current, charge status and load information clearly at a glance.
• Dual USB output (5V/2A) — Charge phones, tablets and devices directly from the controller without a separate inverter.
• Load output with discharge protection — Adjustable discharge cut-off voltage (default 10.7V) protects your battery from deep discharge.
• Adjustable charge parameters — Floating charge voltage, discharge cut-off and recovery voltage all adjustable to suit your battery type.
• Compatible with multiple battery types — Lithium, colloidal (gel) and open-cell (flooded) lead-acid batteries supported.
