Compact 40A MPPT Solar Charge Controller for 12V and 24V Systems Overview A userfriendly MPPT solar charge controller designed for yachts and small offgrid systems. Automatically detects 12V or 24V battery systems, delivers up to 40A charging current, and includes builtin short circuit protection to help safeguard your electrical setup. Key benefits More energy from your panels: MPPT maximum power point tracking optimizes solar input to increase charging efficiency compared to basic controllers. Simple setup and operation: automatic 12V and 24V adaptation removes manual configuration and reduces installation errors. Protects your battery and equipment: integrated short circuit protection and standard charge control functions reduce the risk of system faults. Reliable 40A output: supports moderate solar arrays and battery banks for yachts, small boats, campers, and compact offgrid installations. Spacesaving and robust: compact footprint and durable housing suited to marine and mobile environments where space and vibration resistance matter. Features and performance MPPT maximum power point tracking for improved conversion of solar panel energy into battery charge. Automatic system voltage detection and adaptation for 12V or 24V battery systems. Continuous charging current up to 40A to support common marine and small offgrid loads. Short circuit protection to help prevent damage from wiring faults or reversed connections. Intuitive controls and status indicators for straightforward monitoring and operation. Designed for integration between solar panels and battery banks to manage charging efficiently. Compatibility and use Works with 12V and 24V lead acid and similar battery types commonly used on yachts and small vessels. Verify battery chemistry compatibility before use. Suitable for small to medium solar array sizes where a 40A controller meets the panel and battery current requirements. Practical use scenarios Yacht or motorboat: Manage solar panels on deck to charge the house battery bank and maintain onboard systems while at anchor or under way. Day cruiser or sailing boat: Keep batteries topped up during multiday trips without running the engine, extending time between shore charging. Camper, RV, or tiny offgrid cabin: Provide reliable solar charging for lighting, refrigeration, and electronics in mobile and remote setups. What you get A compact MPPT solar charge controller capable of automatic 12V and 24V adaptation, 40A charging current, and builtin short circuit protection, designed for easy installation and dependable operation in marine and small offgrid applications.
