Commissioning Date30.07.2020

1KW Off-Grid Solar Power System was installed at Kodigehalli Gram Panchayat Office, Nelmangala, Karnataka.

System Details

3 Solar PV Modules of 330Wp were used along with 200AH 12V Luminous C-10 Batteries (1 Nos) to power gram panchayat office that consisted of 3 computers, 3 LED tubelights, 2 fans and CCTV camera system.

High quality Aluminium corrosion free mounting structure was used with anchoring bolts on flat rooftop.

Lumious heavy duty inverter of 1.1KVA was used along with MPPT charge controller in the design. MPPT is programmed to prioritize PV solar power to charge the batteries and power the appliances.  The smart MPPT controller helps to minimize the power consumption from the utility grid and maximize the power usage from the panels.

A MS structure to place the Batteries and Inverter was fabricated and resourced locally. The entire PCU along with Batteries is kept at close distance of 20feet from the solar panel array to minimize the DC current losses.

High qulaity breaker circuits for DC and AC side of the PCU were installed for protection. Further, the overall protection is extended by adding AC, DC isolated earthing circuits and a dedicated lightning arrester.
