System Configuration
Installation example of industrial photovoltaic system
Photovoltaic Facilities
Connection Box, Collection Box
It is a board for collecting DC power generated by the solar cell module and supplying it to the power conditioning system.
A small circuit breaker / switch corresponding to DC circuit is installed.
Power Conditioning System
It inverts DC power generated by solar cell module into AC power that can be used at factories and homes.
Install a DC high voltage circuit breaker on the input side (DC circuit) and AC circuit breaker on the output side (AC circuit).
Voltage Boost System
It is a cubicle for boosting the output voltage from the power conditioning system to a voltage matching the system for the purpose of commercial electric power.
AC circuit breakers are installed.
