Islamabad PV inverter grid change requirements

As much as possible, the inverter should be installed near the utility meter. Shorter the DC cabling less will be the power loss of solar system. Inverters get slightly warm during their operations. To achieve higher performance, there should be adequate ventilation.

Therefore, MoE has desired that the installers of systems for net metering (DG installers) as shortlisted by AEDB will be required to process the application for net metering on behalf of consumers applying for net metering connections up to 250 kW capacity.

Producing electricity partly for own consumption, and partly for sale to the DISCO, is now available in the Pakistan provided anyone has a roof suitable for solar energy. Solar Energy is a long term power solution. The Solar PV Technology gives access to affordable electricity supply during system life.

Anti-islanding is an in built feature in inverter which trips the flow of energy to the grid on grid failure. Installing an anti-islanding enabled inverter is mandatory by the Regulation for Net Metering.

The PV module cables should be properly secured using proper sized ties, not tied with metal wire or ordinary string. Current carrying cable from PV modules to inverter should be DC cable of proper rating, separate colors to identify plus/minus and in UPVC conduit NOT normal PVC conduit.

NEPRA's Rules and Regulations clearly stated that the consumers of Distribution Company are qualified for the net metering process. In case of Bahria town it buys electricity from IESCO and distributes it to the consumers, which makes it a Distribution Company.
