Product Description

Solar Frequency inverter special for solar water pump  
MPPT technology, tracking maximum output power of solar panel
no need batteries
Self protection against over-flow or dry up
BD603 series frequency inverter special for solar water pump adopts the high accuracy fast MPPT algorithms, tracking the PV array output by the maximum power point, driving the pump motor as much as possible to meet various pumping applications.
The frequency inverter special for solar water pump can support AC input besides support PV array DC input. When the PV array can not drive the motor or doesn't have output, it can also accept the grid AC input or other AC motor to supply the power to meet various emergency needs.
BD603 series frequency inverter special for solar water pump provides full protection, maximizing the life of motor and pump
400kw Water Pump 380V Solar Power Inverter

Solar pump drives advantages:

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.


90 to 400VDC input, 110V/160V/220V AC output

200 to 400VDC input, 220VAC output

330-780VDC input, 380VAC output

Descriptions and Features:

Whenever possible, the controller attempts to regulate the pump load in a manner that optimizes for maximum power transfer from the solar array.
1.     Maximize your pump delivery without wasting a watt
2.     Automatic start and stop with Solar irradiation
3.     Self diagnostic and protection
4.     Dry run protection
5.     Dual supply mode - Solar and Grid compatible
6.     Compatible with all pumps with easy operation
7.     Dc current, voltage, power input can be monitor, easy to know power input.
8.     No need parameters setting after pumps correct selecting.
9.     Built in RS485 ports, laptop software control is available,  Remote control management  with GPRS/GPS is option.
10.  Good quality with Infineon IGBT module and other top brand components using. Long term guarantee with 24 months.
