photovoltaic power input satisfies the water outlet conditions; otherwise, it will keep
waiting or switch to the mains supply for operation automatically.
Note: The power switch shall be also connected during the process of automatic
operation and the input end of the solar photovoltaic battery will turn on automatically
after the sunrise. The water pump can operate automatically as long as the operation
conditions can be satisfied. This Inverter will restart to operate again if the starting
conditions can be met even if by pressing “RUN/STOP” key on the panel under
automatic mode to shut it down.
As for the machine that can switch between solar energy and
electric supply, the electric supply will be used automatically if the power of solar
photovoltaic battery is not enough to drive the water pump to yield water. If, however,
the power of the photovoltaic battery is able to satisfy the yielding requirements of
water pump when the electric supply is used, this Inverter will switch to the solar
battery automatically. In other words, the solar battery shall be prioritized. In this way,
the utilization rate of solar battery becomes higher and the water pump can work in
the daytime and at night without battery. It reduces the system costs and expands the
application scope of water pump.
It is prohibited to shut down the water pump by disconnecting the
inverter input when the pump is operated. Instead, cut off the inverter input
after this Inverter stops output; otherwise, it is easy to damage this Inverter.
