What this system decides for your project
The inverter sets real-world efficiency and grid compliance. A reliable, well-matched inverter with monitoring maximises export and flags faults before they cost generation.

Scope of work
Inverter selection follows the array design — string inverters where roofs have several orientations or shading patterns and per-string MPPT protects yield, central inverters where a large uniform array makes them economical — with the DC/AC ratio, the MPPT voltage window and the grid-protection settings the DISCOM's connection standard requires. Monitoring is specified so generation, faults and string performance are visible remotely. We supply and install the inverters, DC combiner boxes, AC distribution and the monitoring hardware.
How it is delivered — and what you receive
Inverters are commissioned with the protection settings — voltage and frequency limits, anti-islanding — configured to the DISCOM's requirements and recorded, because these are checked at the net-metering inspection. Monitoring is verified against the meter, and the client's team is shown the portal. The client receives the settings record, the commissioning report and the monitoring access.
