40A MPPT Charge Controller with Display and Bluetooth
PolarPlus solar controller is based on an advanced maximum power point tracking (MPPT) technology developed, dedicated to the solar system, the controller conversion efficiency up to 98%.
It comes with a number of outstanding features, such as:
> Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9%
> Full digital technology, high charge conversion efficiency up to 98%
> Real-time energy statistics function
> 12/24V automatic recognition
> Liquid, GEL, AGM and Lithium battery for selection
> External temperature sensor, automatic temperature compensation
> Built-in temperature sensor, when the temperature exceeds the set value, the charging current will lower
down followed by the decrease of temperature, so as to control the controller’s temperature rise
> Four stages charge way: MPPT, boost, equalization, float
> With current-limiting charging mode, when the power of solar panel is over-sized and charging current
exceeds the rated current, the controller will lower the charging power, which enables the system to work
under the rated charging current
> Multiple load control modes: Always on, Dusk to Dawn, Evening and Manual
> IoT Wireless Communication, Bluetooth Communication or RS-485 Communication Functions Optional
> Support Android mobile phone APP, realize wireless monitoring function of solar controller
> Use high performance, ultra-low power consumption Bluetooth dedicated chip
> Adopt Bluetooth 4.2 and BLE technology, communication distance up to 10m
> With the wireless communication function of the IoT, the controller can be connected remotely through Iot/GPRS.
> The IoT can monitor and control the system remotely and in real time through the WeChat /PC program
> Real-time automatic fault alarm
> Charging and discharging quantities can be counted and displayed by item grouping and month.
> Based RS-485 standard Modbus protocol, to maximize the communication needs of different occasions.
> Full automatic electronic protect function
> LCD display design, read operating data and working condition easily
