System schematic
Function model
Solar power(PV)Priority Mode PV
In the Solar power (PV) Priority Mode, the loaded power is supplied by the solar panel
AC Priority Mode
In the Solar power (PV) Priority Mode, the loaded power is supplied by the mains supply input and is outputted to the load through the voltage regulator and the isolation parts to ensure the stability of the outputted power source AC
Energy mode
In the Energy mode, the user can set up the time to charge, set the grid to charge the battery pack at a certain time
Bypass Supply
In the bypass supply mode, the mains supply will directly pass the bypass switch and shift to load power supply. The system will directly enter into bypass supply under the following circumstances (Attention: While there is a bypass supply, there must be a mains supply input)
System Characteristics
Adopt high capacity, high safety LiFePO4 battery
Have two modes off-grid and on grid
can wait for ac power generation and photovoltaic power generation equipment of small micro network system
Adopts modular design, easy to install
