MAIN FEATURES

– With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.

– A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.

– The product boasts an optimum MPPT tracking efficiency of up to 99.9%.

– Different charging program options including those for gel batteries, sealed batteries and open batteries, customized ones, etc. are available.

– Automatic recognition of battery voltage is supported.

– LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults.

– The controller employs a built-in over-temperature protection mechanism.

– TVS lighting protection

– Three stage battery charging (quick, equilibrium and float)

– RS 232 communication

– Natural cooling
