Make more of every available ray of sunshine with this 40A MPPT solar charge controller, designed for dependable off-grid solar charging. It is a practical choice for homeowners, installers, farms, workshops and solar working stations that need to manage battery charging across 12V, 24V, 36V or 48V systems. Advanced Maximum Power Point Tracking helps the controller optimise energy harvested from your solar panels, while the clear blue-backlit LCD gives you an at-a-glance view of system activity. With support for up to 2270W of PV power, it is built for serious solar setups rather than small, basic installations.
Key Features & Benefits
- MPPT charging technology tracks the solar array’s maximum power point to help draw the best possible charging performance from changing sunlight conditions.
- Up to 99% MPPT efficiency helps minimise wasted solar energy, giving your batteries more opportunity to charge efficiently throughout the day.
- 12V/24V/36V/48V auto system voltage delivers flexible compatibility for a wide range of off-grid battery bank configurations.
- 2270W maximum PV power provides ample capacity for larger solar panel arrays and higher-demand standalone power systems.
- 150VDC maximum PV input voltage supports solar array configurations suited to robust off-grid installations.
- LCD status display visibly presents solar, battery and charging information, making everyday monitoring simpler without extra equipment.
- Easy front-panel controls include dedicated menu, up, down and enter buttons for straightforward local settings navigation.
- Broad battery compatibility supports lead-acid, GEL and LiFePO4 batteries, helping you build or upgrade a system around your preferred battery technology.
- RS485 communication port provides a convenient connection point for compatible monitoring or system communication requirements.
- Clearly marked connections for solar panel, battery and DC load make installation points easier to identify in an organised solar setup.
Design & Build
The controller has a smart, professional silver-grey and black enclosure with prominent MPPT solar charge controller branding on the front. Its compact rectangular form is designed for fixed installation, with sturdy black side mounting brackets featuring multiple slotted mounting holes. The front control area is neatly recessed into a black panel, creating a clean contrast around the illuminated LCD and blue buttons. Ventilation openings on the side and a guarded cooling fan at the rear are visible in the photos, while the connection panel includes labelled terminals, an RS485 socket and a dedicated temperature sensor port.
Ideal For
This MPPT solar charger controller is well suited to off-grid homes, cottages, container offices, farms, borehole or agricultural support systems, workshops, security installations and mobile solar power stations. It is a strong option where battery-based solar power needs to operate around the clock, with a DC load connection available for compatible DC equipment. Whether you are specifying components for a new system or replacing an existing controller, its multi-voltage operation and battery flexibility make it a versatile choice for professional solar installations.
