Detailed introduction

1. With MPPT functions, applicable to monocrystalline, polycrystalline and amorphous silicon solar panels serially connected in various numbers

significantly improving the solar panels' energy utilization ratio.

2. Adopts the MPPT solar charging technology, with a max. solar panel open-circuit voltage Voc ≤ 60V and a max. solar panel power Pm ≤ 400W.

Supports a load output current of 15A and a 0-10V dimming function.

3. Adopts an improved charging algorithm that supports 12V and 24V lead-acid batteries and lithium batteries, and the user can set the operating modes for lead-acid batteries or lithium batteries accordingly.

4. With a load triple-stage brightness adjustment and morning on design, with an operating duration adjustable from 0 to 15 hours and a power settable from 0 to 100%.

5. With a system status log function, able to record a maximum of 7 days of system status, comprehensively and effectively monitoring the system's conditions.

6. Data communication adopts a multi-time two-way handshake protocol and a data compression algorithm, realizing precise and fast data transmission.

7. With an intelligent power mode which can extend the battery life to its top limit by adjusting the dimming signal voltage (0-10V) automatically according to the remaining battery capacity.

8. With an infrared remote control function, operations including setting parameters, reading status and viewing historical data can be conducted remotely.

9. A metal case and an IP68 waterproof level enable the device to operate in various kinds of tough conditions.

10. An overheat protection function enables the device to scale down the load or shut off the load completely when its temperature exceeds a certain point.

11. A range of protection measures such as battery reverse-connection protection, load short-circuit and overload protection, etc., put the system under comprehensive and constant guard.

The following are functions of the "-U" series

1. With a wireless Internet communication function, able to conduct remote monitoring and real-time management on street lights via the solar power street light management system.

2. Supports remote light on/off switching and dimming, as well as modification of battery and load parameters.

3. Monitors solar panel voltage, current and power, battery charging and discharging current and voltage, load operating status, controller operating status and other data, and automatically triggers alarms when failures are detected.
