Introduction：

        The controller adopts the leading PowerCatcher maximal power Tracking technology in the industry to
achieve maximal energy Tracking for solar panel, so that it can quickly and accurately trace the maximal power
point of the solar battery, acquire the maximal energy of the solar panel and significantly improve the energy

utilization ratio of the solar system. Widely applied to solar off-line photovoltaic system for managing solar panel

and storage battery in operation, the controller is the core control component of off-line photovoltaic system.

        The inside of the controller possesses sound electronic failure detecting and protection function to avoid the

product component damage caused by installation error and system failure.

        The controller is equipped with an LCD display screen to simultaneously support data interaction, setting

and other operations with mobile phone APP, PC upper computer and other devices.

Feature：

1、PowerCatcher maximal power Tracking technology can still trace the maximal power point of solar battery in the

complicated environment. Compared with traditional MPPT Tracking technology, it enjoys higher response speed

and higher Tracking efficiency.

2、MPPT charge efficiency is greater than traditional PWM charge efficiency by about 15% ~20%.

3、MPPT Tracking efficiency can be as much as 99.9%.

4、Adopting advanced digital power technology, the circuit energy conversion efficiency can be as much as 98%.

5、The products support lithium batteries, charging output has active voltage stabilization function. In case of open

circuit of lithium batteries or BMS overcharging protection, the storage battery end of the controller shall output

stable target voltages in time, thereby possessing good lithium electric activation function.

6、Preset a variety of battery types: lithium batteries, sealed batteries, colloidal batteries, open batteries and self-

definition.

7、Lead-acid batteries support temperature compensation function.

8、With charging line loss compensation, the voltage of the battery terminal can be accurately controlled.

9、With current-limiting charging, in case of too much battery panel power (charging current is greater than rated

current), the controller automatically reduces the charging power so that it can operate within the rated charging

current.

10、With built-in overtemperature protection mechanism, when the temperature exceeds the set temperature value,

the charging power shall decline in a linear way with the temperature.

11、It supports parallel function and breaks through the power limit of single unit. Therefore, combination of several

units can meet greater charging power.

12、With built-in bluetooth 4.0BLE module, it can achieve mobilephone APP data interaction.

13、Supporting standard Modbus protocol, it provides protocol technology support to facilitate secondary

development and application by users.

14、Programmable relay output
