Compact, high-efficiency MPPT charge controller for 12/24 V off-grid systems. Supports PV voltages up to 150 V and delivers a 40 A charge current.

• MPPT Technology: This solar charge controller uses the most advanced Maximum Power Point Tracking (MPPT) to maximise harvest and ensure high efficiency (>95%).
• PV input and power limits: Supports PV open-circuit voltages up to 150 V and maximum solar power of 520 W (12 V system) or 1040 W (24 V system).
• Full system protection: Features reverse current prevention at night (battery back to the solar panel), automatic over-charge cut-off, deep-discharge protection, panel over-voltage, overload, short circuit and reverse polarity; includes self-diagnostic and optional audible alarm.
• Multiple connectivity options: The controller can be connected to a remote meter MT50 with an LCD screen; communication port: RS485/RJ45 interface for monitoring and programming.
• Grounding & current limiting: Grounding: negative common ground. Current limiting function (40 A) allows potential system expansion with additional panels.
• Controller specifications: Self-consumption <60 mA (12 V), <30 mA (24 V); comprehensive electronic protection features.
• Environmental & physical: Working temperature -35°C to +55°C (-31°F to +131°F); Size: 30.2 x 18.2 x 6.8 cm (11.9 x 7.2 x 2.7 in); Weight: 2.9 kg (6.4 lb).
• Design & installation: Die-cast aluminium body for excellent heat dissipation, multiple mounting holes for ease of installation. The product is covered by warranty (see manual) and the package includes a detailed user manual.

Installation note: The controller automatically recognises 12/24 V battery systems — always connect the battery before connecting the solar panel. LED indicators show charging status and battery condition; refer to the user manual for wiring, operation and compatibility details.
