China best smarten 20a 30a 40amp 50amp mppt solar pv power charging controller 2kw 3kw with lan OEM for home uk australia

1. Outstanding Features :

1. Built-in algorithm for maximum power tracking. MPPT tracking efficiency can be as high as 99.9%.
Advanced digital power technology, with circuit energy conversion efficiency as high as 98%.

2. Advanced double-peak or multiple-peak tracking technology. When the panel has a shadow block or a part of the panel is damaged, I-V curve shows multiple peaks. The solar charge controller can still accurately track the maximum power point.

3. Current-limiting charging mode. When the power of a solar panel is too large, and the charging current is greater than rated current, the solar charge controller automatically reduces charging power, thereby making the solar panel work at rated charging current.

4.  External LCD screen or Bluetooth module can be connected for viewing of equipment operating data
and status, and modification of controller parameters is supported.

5. Supporting standard Modbus protocol that meets communication needs on different occasions.
6. Temperature compensation functions. Charging and discharging parameters are automatically adjusted, thereby extending battery service life.

7.  Built-in over-temperature protection mechanism ensures that when temperature exceeds the set value
of the device, the charging current decreases linearly with the temperature, thereby reducing the
temperature rise of controller and avoiding high temperature damage.
