Solar controller MPPT 20A SRNE - ML2420

With advanced double-peak or multi-period tracking technology, when the solar panel is shaded or part of the panel is shaded, resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum feed-in point.

An integrated power point tracking algorithm significantly improves the energy utilization efficiency of photovoltaic systems, increasing load efficiency by 15% to 20% compared to conventional PWM.

A combination of several tracking algorithms enables precise tracking of the optimum working point on the I-V curve in an extremely short time.

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

Advanced digital power supply technologies increase the circuit's energy conversion efficiency by up to 98%.

Charging program options are available for different battery types, including gel batteries, sealed batteries, open batteries, lithium batteries, etc.

The controller features a current-limited charging mode. When the solar panel power exceeds a certain level and the charging current exceeds the rated current, the controller automatically lowers the load and brings the charging current down to the rated level.

Immediate start-up of a large capacitive charging current is supported.

Automatic battery voltage recognition is supported.

LED fault indicators and an LCD screen that can display information in the event of an anomaly enable users to quickly identify system faults.

Historical data storage is available, and data can be stored for up to a year.

The controller is equipped with an LCD display with which users can not only check device data and operating status, but also modify controller parameters.

The controller supports the standard Modbus protocol, meeting the communication needs of a variety of occasions.

The controller features a built-in overheating protection mechanism. When the temperature exceeds the set value, the load current decreases in linear proportion to the temperature in order to slow down the temperature rise in the controller, thus preventing the controller from being damaged by overheating.

With a temperature compensation function, the controller can automatically adjust charging and discharging parameters to extend battery life.
