Advanced MPPT Solar Charge Controller for 12 V and 24 V Systems A efficiency solar charge controller available in 20 A and 30 A versions, designed for offgrid systems in homes, RVs, boats, and remote sites. Combines precision MPPT tracking, a readable LCD for realtime status, and multilayer protections to manage battery charging and load control reliably. Key benefits Maximize solar harvest: Precision MPPT tracking with greater than 99.9 percent MPPT efficiency and up to 98.0 percent overall charging efficiency helps extract more energy from the same solar array compared to conventional controllers. Clear, realtime information: Builtin LCD shows PV input, battery voltage and state, and load conditions for quick system checks at a glance. Reliable protection and temperature compensation: Multilayer protection against overcharge, reverse polarity, short circuit, and overcurrent plus automatic temperature compensation to protect battery life and system performance. Flexible operation: Supports 12 V and 24 V battery systems and three operating modes for different setups and user preferences.
