Detailed introduction

1. Features true 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。 MPPT solar charging technology, the maximum solar input voltage Voc ≤ 60V。
3. The load is stepping up and constant current output which can support maximum 18pcs of LED beads connected in series.
4. Adopts an improved charging algorithm that supports 12 V and 24 V lead-acid batteries and lithium batteries, and the user can set the operating modes for lead-acid batteries or lithium batteries accordingly.
5. Boasts 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%.
6. Features a system status log function, able to record a maximum of 7 days of system status, comprehensively and effectively monitoring the system's conditions.
7。 Data communication adopts a multi-time two-way handshake protocol and a data compression algorithm, realizing precise and fast data transmission。
8. Features an intelligent power mode which can extend the battery life to its top limit by adjusting the load power automatically according to the remaining battery capacity.
9. True constant current rather than current-limiting control ensures smooth and stable output current, effectively reducing LED light attenuation and extending LED service life.
10. With an infrared remote control function, operations including setting parameters, reading status and viewing historical data can be conducted.
11. A metal case and an IP68 waterproof level enable the device to operate in various kinds of tough conditions.
12。 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。
13. A range of protection measures such as battery reverse-connection protection, LED short-circuit and open-circuit protection, etc., put the system under comprehensive and constant guard.
