Product overview A control unit designed for off grid photovoltaic systems to coordinate solar panels, batteries, and loads. The controller monitors panel output in real time and tracks the voltage and current values to charge batteries at maximum power. Key benefits Maximizes energy harvest: Built in MPPT algorithm continuously finds the solar array operating point that yields the power, improving usable energy by 15% to 20% compared with traditional PWM controllers. tracking and conversion efficiency: MPPT tracking efficiency up to 99.9% and circuit energy conversion up to 98% reduce lost energy and increase overall system performance. Adaptive charging for multiple battery types: Supports gel batteries, sealed batteries, elastic batteries, and lithium batteries with selectable charging modes to match battery requirements. Automatic current limiting: When solar input would push charging current above the controller rated value, the controller automatically reduces charging power so charging current stays at the rated level and conversion efficiency is improved. Centralized system control: Acts as the core control unit of an off grid PV system, coordinating panels, batteries, and loads to optimize operation and battery life. Core functions and performance Real time monitoring of solar panel power generation with continuous VI tracking for voltage and current values.
