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

High efficiency 30 A MPPT solar charge controller with dual stabilised 12/24 V load outputs, suitable for off-grid systems with PV input up to 100 V Voc and up to 390W (12 V) / 780W (24 V).

• Dual stabilised 12/24 V load outputs: two independent, voltage-stabilising load outputs provide a consistent, low-ripple supply; each output can be set independently to 12 V or 24 V regardless of battery voltage, allowing mixed 12 V/24 V loads without extra converters.
• MPPT technology: advanced Maximum Power Point Tracking (MPPT) for high conversion efficiency (>95%); wide PV input range up to 100 V Voc; supports up to 390W for 12 V systems or 780W for 24 V systems.
• Full system protection: comprehensive electronic protections including reverse current prevention at night (battery to solar panel), automatic over-charge and deep-discharge cut-off, solar panel over-voltage protection, over-load and short-circuit protection, reverse-polarity protection, plus self-diagnostic and advanced fault-targeting functions.
• Lithium battery charging: compatible with LiFePO4 and Li(NiCoMn)O2 lithium chemistries, and with sealed/AGM/gel lead-acid batteries; user-definable charging profiles available.
• Advanced system functionality: the two load outputs operate independently of battery voltage to provide stable power for sensitive equipment such as CCTV and telecommunications, and to support mixed-voltage installations from a single controller.
• Connectivity and control: communication port RS485 (RJ45), negative common ground, current limiting function; can be connected to a Wi-Fi module for remote monitoring and configuration.
• Controller specifications & performance: nominal charging current 30 A; conversion efficiency >95%; self-consumption ≤35 mA (12 V) / ≤22 mA (24 V); operating temperature -30°C to +65°C.
• Mechanical & installation: dimensions 17.8 x 12.0 x 3.5 cm; mounting dimension 12 x 15.3 cm (4.7 x 6.0 in); weight 1.5 kg (3.3 lb); multiple mounting holes (5 mm diameter) for easy installation; detailed user manual included (wiring and settings).
• Applications: suitable for boats/marine, RV, CCTV, telecommunications and mixed-voltage off-grid installations — consult the supplied manual for wiring, settings and compatibility details.
