Sun great series solar water pumping features:
Software design with dual MPPT tracking.
* Dual supply mode - Solar DC and Grid AC compatible input.
* Compatible with all 3 phase pumps, IM And PMSM
* Possible to drive for 1 phase 220AC pumps with or without starting capacities.
* Dry Run Function for pumps protection when lack of water in well.
* Automatic Start And Stop With Solar Irradiation/ Manual
* Lowest stop Frequency setting.
* Pumps Max Current Setting,
* Water Tank fulling Level Detect Function,
* Flow And Generated Energy Calculating And Monitor without sensor
* GPRS Remote Control Is Option-- working status real time monitoring, history working data reorder, remote start/stop including the parameters modify.
* Maximize your pump delivery with MPPT function, better water delivery than other brand.
Hardware design:
*Innovation design with dual CPU, one CPU responsible for function, one CPU responsible for performance controlling.
*Good ventilation with low temperature rising
*Full fault protection design to minimize iGBT damaged
*Infineon iGBT module,
*Long term service lift design
*Enhanced lightning protection for outdoor using safe.
* Adding DC current sensor (halls) are good for MPPT tracking and damaged protection.
