efficiency MPPT controller designed for low standby drain, flexible load control, and clear system monitoring. Key benefits Ultralow standby consumption: Builtin ultralow power consumption chip minimizes static standby energy use and reduces energy loss at night, helping extend battery life and lower system losses. Proven MPPT performance: Advanced MPPT controller algorithm delivers MPPT efficiency not less than 99.5 percent, with wholeunit conversion efficiency up to 98 percent for improved energy harvest and conversion. Flexible load management: Multiple LOAD modes provide installation and control flexibility, including normally open and normally closed configurations, light control mode, dual time control mode, and light control plus fixed time control mode. Clear, intuitive monitoring: Onscreen display presents all sampling data clearly, making system checks and troubleshooting straightforward for installers and operators. Core functions and compatibility MPPT control algorithm for maximum power tracking and efficient PV array utilization. Load output configurable for different control strategies and wiring conventions using normally open or normally closed contacts. Light sensing and timebased controls can be combined for automated dusktodawn, scheduled, or mixedmode operation. Displayed sampling data covers key system parameters, enabling quick verification of voltage, current, power, and operating modes. Performance highlights MPPT efficiency not less than 99.5 percent to maximize solar energy capture. Wholeunit conversion efficiency as as 98 percent to minimize losses in the power path. Ultralow power consumption in standby to reduce overnight energy loss and lower parasitic drain. Typical applications Offgrid lighting and street lighting systems where overnight standby losses must be minimized and light or timer control is required. Remote cabins, telecom shelters, and small offgrid sites that need efficient MPPT charging and clear status monitoring. Mobile systems such as RVs and boats that benefit from conversion efficiency and flexible load control modes. What users gain Lower operating losses and improved energy yield through MPPT and conversion efficiency. Flexible load control to match a wide range of lighting and timed applications. Easier system operation and maintenance with an intuitive display of sampled data. Note Functions include ultralow power standby, multiple load modes, onscreen sampling data, and an MPPT algorithm with the efficiency specifications stated above.
