Take control of larger solar battery installations with this powerful 120A MPPT solar charge controller. Designed for installers, solar professionals, farms, workshops and off-grid power users, it intelligently converts available solar energy into efficient battery charging throughout the day. Its standout high-capacity design supports up to 6800W of PV power, while the front LCD display, practical control buttons and clearly labelled connection terminals make everyday monitoring more straightforward.
Key Features & Benefits
- 120A charging capacity suits demanding solar battery systems that need to manage substantial charging current.
- MPPT charging technology continually tracks the solar array’s optimum operating point to help extract more usable energy from sunlight.
- Up to 99.9% MPPT efficiency helps minimise wasted solar potential for efficient energy harvesting.
- Supports up to 6800W PV power at 48V, making it a capable choice for larger residential, commercial and off-grid solar installations.
- 150VDC maximum PV input provides flexibility when configuring compatible higher-voltage solar panel strings.
- Three-stage charging combines constant-current MPPT charging, equalising charge and float charge for a managed charging process.
- Broad battery compatibility supports Gel, SLA, AGM, flooded/water and lithium LiFePO4 battery types.
- Integrated LCD screen and keypad put key charging and system information within easy reach at the controller.
- RS485 communication port enables connection options for a compatible WiFi box or external control screen.
- Dedicated terminal layout includes labelled solar panel, battery and DC load connections, plus a temperature sensor input for organised installation.
Design & Build
This MPPT solar charger controller has a professional silver enclosure with a bold blue centre panel and contrasting black end sections. The front-mounted LCD is recessed into a black control panel with four blue function buttons, giving the unit a neat, purposeful appearance. Side mounting rails with multiple fixing slots make it suitable for secure wall or panel mounting, while the clearly arranged green terminal blocks help keep solar, battery and DC load wiring easy to identify. Ventilation openings and two visible cooling fans support airflow around the unit, while the robust, box-style construction is well suited to fixed solar installation environments.
Ideal For
This 120A MPPT controller is ideal for high-output 48V solar battery systems in homes, backup-power installations, farms, small business premises, workshops, containerised power setups and remote off-grid sites. It is a strong option where a conventional small solar regulator is no longer sufficient and a larger PV array needs intelligent battery charging. The DC load terminals also make it useful for systems incorporating compatible direct-current loads alongside battery storage.
