DC Solar Pump With Permanent DC Brushless Synchronous Motors
Advantage of DC solar pump
1. Permanent DC brushless synchronous motors: The efficiency is improved by 15%--20%;
2. Save energy;
3. Reduce the energy of solar panel;
4. 304 S/S pump shaft;
5. Brass or stainless steel outlet/connector/oil cylinder;
6. Alloy mechanical seal: Longer working lift and high reliability;
7. Motor coil is made by automatic winding machine with centralized winding technology, motor efficiency in much improved;
8. Intelligent water shortage protection; The pump stops working automatically when there is no water in the well, and automatically start working 30 minutes later.
9. Controller:
a) Water proof grade: IP65;
b) Ambient temperature: -15°C---60°C
c) MPPT function, the solar power utilization rate is higher
d) Automatic charging fuction: guarantee the pump normally working, meanwhile charge the battery; and when there is no sunshine,the battery can make the pump constinuously working
e) LED display the power, voltage, current, speed etc working condition
f) Frequency conversion function: It can automatically run with frequency conversion according to the solar power, and user also can change the speed of the pump automatically
g) Automatically start and stop working
h) Water proof and leak-proof, double seal effect
i) Soft start: No impulse current, protect the pump motor
j) High/Low voltage/Over-current/High temperature protection
