KEWO-Sun great series Solar Pump Drives
Solar pump drives advantages:
Kewo sun great series solar pump drive is positioned in environmental-friendly and economical PV market, the product is applicable to PV pumping system, replaces water storage with electric storage and needs no battery modules. The direct current generated by solar modules is input to the inverter and then converted into the alternating current to drive various pumps directly. Additionally, the output frequency is adjustable in real time according to sunlight intensity change.
Specification:
90 to 400VDC input, 110V/160V/220/240V AC output, 0.75/1.5kw.
200 to 400VDC input, 220-240VAC output, 0.75 to 3.7kw
400-8000VDC input, 380-480VAC output, 0.75 to 110kw
Descriptions and Features:
1. Built-in MPPT function, Maximum power point tracking functionality ensures that you get the most power output possible from your solar panel and maximizes the performance of your pump throughout the day.
2. Built-in flow measurement and sensorless flow calculation. And easy to get how much energy generated by this system with generated energy and calculating
3. Advanced function automatic start and stop of the drive when there is enough power available. ( auto/manual)
4. Multiple pump motors with a single drive control standard asynchronous motors as well as more efficient permanent magnet synchronous motors. (PMSM)
5. Best off-grid solution Where electricity is very erratic and unpredictable, farmers need not to depend on grid electricity for their agricultural requirements
. Remote monitoring With the addition of optional GPRS modules you can monitor and configure drive and application parameters from anywhere via Modbus RTU
Protection features:
Electronic monitoring gives the controller the capability to monitor the system and automatically shut down in the even of: Dry run conditions- with smart pump monitoring, High voltage surge, Low input voltage, Open motor circuit, Short circuit, Over heat, Earth fault, Phase missing…
