48VDC high efficiency solar well pumps and DC controller
Automatic dc Submersible Solar Water Pump

Product Description
Irrigation water pump from river with solar is mainly used for all kinds of water supply and drainage, fountain, solar system and all other field requires 10m-200m head solar water pump irrigation, widely used in industries, 
agricultural irrigation,  petrochemical industries, medicinal industries, and all kinds of water process.
There are two solar pump controller system.
1.Solar DC pumps  system 
a, Low DC input,
b, small flow output compare to AC pumps with low power. up to 0.75kw
c, low cost invest
2. Solar 3 phase AC pumps system
a, Need high DC input ( 310VDC for 220V  AC pumps, 540VDC for 380VAC pumps)
b, Large flow output, big water head is available, power form 0.75kw to 400kw
c. Big cost invest original
** Features of new PMSM solar DC pumps system.
High efficiency, small size, light weight, more functions
MPPT function
Automatically working function
Work with both solar power and electricity, can connect with solar panels and AC electricity at same time, 
will use solar power in advance which is more higher efficient than MTTP function. 
Do not need float switch, if there is no water in well for 1 minute, solar water pump dc brushless will stop working automatically. After 30 minutes, pump will start automatically power on to test whether there is water or not.
When power on the solar pump system, controller will detect the system of energy source to see it is solar panels or batteries, then start working. 
If there is solar power then use solar power, if no so ar power will use batteries automatically.
