High Efficiency 30A MPPT Charge Controller 12/24V 100V | 4Boats

Reliable 30 A MPPT charge controller for off‑grid 12/24 V battery systems, offering wide PV input (up to 100 V Voc), advanced protections and system monitoring.

• MPPT Technology: This solar charge controller uses the most advanced Maximum Power Point Tracking to maximise energy harvest and operate with higher PV voltages.
• Maximum PV input: 390W for 12 V battery systems or 780W for 24 V systems; input/open-circuit voltage up to 100 V (Voc).
• High efficiency: MPPT conversion efficiency >95% for improved system performance.
• Full system protection: reverse current prevention at night, over‑charge and deep‑discharge cut‑off, PV over‑voltage, overload, short circuit and reverse polarity protection, plus self‑diagnostic fault indication.
• Lithium battery charging: compatible with lithium batteries when the lithium charging programme/profile is selected via PC software or mobile app.
• Advanced system monitoring: the controller automatically recognises 12/24 V battery systems (note a battery should be connected before the solar panel); built‑in LCD displays voltage, current, state of charge and accumulated charge/discharge energy; user buttons to select battery type and set load timers.
• Multiple connectivity options: supports remote meter MT50 with LCD, and RS485/RJ45 interface for PC or mobile app monitoring and programming.
• Controller specifications: negative common ground; current limiting function 10 A (10 A load/output limit separate from the controller's 30 A maximum charging rating — used for load protection/configuration); self‑consumption <12 mA; working temperature -25°C to +50°C; size 22.8 x 16.4 x 5.5 cm; mounting dimension 17 x 16.4 cm; weight 1.26 kg; multiple mounting holes (5 mm diameter).
• Refer to the downloadable User Manual for Photonic Universe High Efficiency 30 A MPPT solar charge controller for setup, wiring diagrams and full specifications. Ensure the battery is connected before the solar panel during installation.
