Redesign and Install Grid Tied 5KW Inverter for PKH Aoral

In January 2019, we removed all the stand alone photovoltaic systems in Aoral (1kW & 600W) and Trang ( 450W & 450W) and rewire and relocate them in PKH Aoral to make a Grid Tied 5KW Inverter system since Aoral has government electricity.

The Grid Tied 5KW Inverter system has 10 solar panels connected in series (180Vdc) and 4 batteries connected in series (48Vdc).


In operations, the sun charges the battery and the government supply electricity to PKH Aoral Training Centre when it is cloudy.
 When is sun is shinning brightly, the solar provides electricity to the PKH Centre and also feed back electricity to the grid.
When the government electricity supply is cut-off, the centre uses the solar power.
When the sun is shinning brightly, electricity from the solar charges the battery and also supply electricity back to the grid.
