More info





With advanced double-peak or multiperiod tracking technology, when the solar panel is shaded or part of the panel, causing several spikes on the I-V curve, the controller is always able to accurately track the maximum power point.

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

A combination of several tracking algorithms allows accurate tracking of the optimal working point on the I-V curve in an extremely short time.

The product has an optimal MPPT tracking efficiency of up to 99.9%.

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






The charging program options are available for different types of batteries, including gel batteries, sealed batteries, open batteries, lithium batteries, etc.

The controller has a limited current charge mode. When the power of the solar panel exceeds a certain level and the charge current is greater than the nominal current, the regulator automatically lowers the load and brings the charge current to the nominal level.

The immediate start of a large capacitive charging current is supported.

Automatic battery voltage recognition is supported.

LED defect indicators and an LCD screen that can display information in the event of an anomaly allow users to quickly identify system defects.

The historical data storage function is available and the data can be stored for up to a year.

The controller is equipped with an LCD screen with which users can not only check the device's data and operating states, but also change the controller's settings.

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

The controller uses an integrated mechanism to protect against overheating. When the temperature exceeds the set value, the charge current decreases in linear proportion to the temperature to slow the rise in the regulator's temperature, preventing the controller from being damaged by overheating.

With a temperature-clearing function, the controller can automatically adjust the charge and discharge settings to increase battery life.
