MPPT Solar controllers (Maximum Power Point Tracking) can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by 10% to 30%.
This series of controllers can effectively prolong the life-cycle of batteries, significantly improving the systems performance. The load, utility or generator auto-control relays make it ideal to use with a solar power system and backup generator. All-around electronic protections, including overcharging, over discharging, and PV reverse polarity protection this effectively ensure a safe and reliable solar system. The isolated RS485 interface with standard MODBUS communication protocol and 5V power supply makes it easy for customers to expand the control parameters. Up to 8 controllers can be in linked in parallel for synchronised charging to meet future system expansions and monitoring requirements.
