Working Principle:
Normally,the power system runs in a parallel floating charge
state,that is,the rectifier module,solar module,load,and battery
work in parallel.Solar modules and rectifier modules provide
floating charge current for power communication devices and
batteries.If the output power of the solar module is insufficient
to feed all the loads,the rectifier module will provide
supplementary power for the communication devices.
When the mains power is off,the rectifier module stops working.If
the solar power supply is normal,the solar module will feed the
communication devices and charge the battery.If the output power of
the solar module is insufficient to feed all the loads,the battery
will provide supplementary power for the communication devices.
When the mains power is off,the rectifier module stops working.If
the solar energy fails at the same time,the communication devices
will be powered by batteries.When the battery discharge continues
for a period of time to the point of the generator start,.the
monitor sends start signal to the generator.Generator provides AC
input power for the rectifier module,then the rectifier can supply
power to the communication devices again and charge the battery to
compensate for the consumption.When reaching the stop point of the
generator,the monitor unit sends out a stop signal to the
generator,and the generator turns off.
