SmartSolar MPPT charge controllers

Ultra-fast Maximum Power Point Tracking (MPPT): Especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10 % compared to slower MPPT controllers

Load output: Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a preset voltage

BatteryLife: intelligent battery management. The BatteryLife algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%

Resin encapsulated electronics

Day/night timing and light dimming option

Outstanding conversion efficiency: No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F). No cooling fan

Advanced Maximum Power Point Detection in case of partial shading conditions: If partial shading occurs, two or more maximum power points may be present on the power-voltage curve. Conventional MPPT’s tend to lock to a local MPP, which may not be the optimum MPP. The innovative BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP

Flexible charge algorithm: Fully programmable charge algorithm, and eight preprogrammed algorithms, selectable with a rotary switch

Extensive electronic protection: Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection
