Design & Construction of Solar Inverter Substations

Date:
Duration: 1 hours

The rapid increase in the construction of photovoltaic (PV), grid-tied solar farms has created a surge in the demand for utility-grade inverters. These inverters convert the DC current generated by the PV cells into low voltage AC power. The inverters are coupled to a distribution transformer then stepped up to medium voltage, generally 12 kV or 34.5 kV, for collection in an interconnect substation. The interconnect substation steps the voltage up again to the utility transmission voltage, generally in the 69 kV to 345 kV range.

While many inverters consist of a durable enclosure that can withstand normal weather conditions, developers prefer constructing a walk-in, metal enclosure to protect the inverters and other power equipment from extreme conditions and better manage air flow around the equipment. These pre-wired, outdoor-rated inverter enclosure reduces project engineering costs, accelerates project schedules, and significantly decreases the cost of on-site labor and installation. In addition, the power equipment line-up also includes fully redundant DC combiner boxes, step-up transformers and medium voltage switchgear. Numerous designs have emerged over the past year including options for cooling, transformer location, and the like.
