Grid-connected Solar Inverter (DSI Series)
- It supplies the power to the system, which is generated from the solar cell after converting it into a three-phase power through the inverter.
- With the high power generation efficiency and reliability, the maximum power follow-up control capability, the power factor control, the unmanned facility operation through a self-diagnostic system, it normally produces the maximum power and it is suitable for large power plants.
DSI Series 'T' Type(Isolation Transfomer) Specification
- Transformer type inverter (for outdoor) 380Vac Output Voltage fixed
- In case there is no incoming panel, isolated transformer is installed inside of the inverter electrical box in order to have same power output, so it could be supplied the same amount of power output with the output voltage.
