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.

Power Usage at PKH Trang, Cambodia

From August 2017 to end of January 2018, the total energy consumption at the training centre is 1,367 watts-hour. If we charges 20 cents per KW-Hr, this would cost them USD 273.40 for 6 months and compared with diesel generator costing USD 80 monthy or USD 480 for 6 months.

Construction of Mission House, Trang, Cambodia.

Construction of Trang Mission House started in February 2018. 

They started to fabricate solar stand supports to mount 40 pieces of 50 watts solar panels on the roof.

This will provide a 2KW Photovoltaic System for the Mission House.

The Mission House was completed on 14 March 2018, just in time for visiting medical and dental Mission teams to conduct health and dental checks for the 350 children and to villagers of the Suoy Community. The Mission House will also provide residence for the Mission staff.
