Solar Pump Controller,LCB 15A 36V with LCD Display,DC Pump Controller,Linear Current Boosters Used in Solar Direct Pumping Applications;Compatible Models: 36 VDC Pumps; Input Voltage: 16 - 90 VDC

• The solar water pump system is mainly used for gardens, pastures, farms, mines, and household water. It is a solar water pump system that does not require batteries.The system includes solar panel; LCB（Solar pump controller）; water pump,;switch float and tank.
• Solar direct – the power of the sun, without maintaining a battery bank. The most efficient way to use a solar pump is solar-direct, powering the pump directly off the solar panel, without using batteries. Rather than experiencing losses through storing power in batteries, the water itself is stored to be used when needed. It’s much easier to store water than power.
• The product offered here is a DC pump controller for 36 volts ONLY. If you have terminals/wires on your pump labeled [u v w], [x y z] or T1 T2 T3, it is very likely a 3 phase AC pump. THIS WIRING CONFIGURATION IS NOT COMPATIBLE WITH THIS SOLAR CONTROLLER. A 3 phase AC connection will be required.

Always Yellow Wire connect to the float switch wire, The other float switch wire connect to the negative PV, the negative PV connected to be grounded. If there is no float switch, please ignore the yellow wire connection.
