Renewables & Solar
Grid-connect PVDBs, BESS DC panels, and DNSP-compliant MSBs.
Utility-scale solar and battery projects need switchboards that integrate with inverters, BESS units, and DNSP protection schemes. Our designs meet AS/NZS 4777 and the relevant network connection standards across all NEM regions.

From rooftop C&I to utility scale
We design and build switchgear from 100 kW commercial rooftops to 50 MW solar farms with BESS. The engineering challenge changes — grid-forming inverter integration, FCAS contract compatibility, DNSP protection scheme alignment — but the rigour doesn't. Every project ships with a verified protection settings file.

DC switchgear done right
BESS DC switchgear is unforgiving. We design for arc-fault detection, pre-charge sequencing, and isolation under fault — not just rated current. Our DC panels are tested under load and shipped with documented commissioning procedures for the inverter platform you've specified.
Built to spec, every line.
