800 VAC Solar Switchboards

Built for the Demands of Renewable Energy Systems
Solar power introduces unique challenges for electrical distribution–intermittent generation, bidirectional power flow, utility interconnection requirements, and evolving code compliance. Solar switchboards from SEG are engineered to meet renewable energy demands, bridging the gap between photovoltaic arrays and commercial or utility-scale power systems.

We deliver rugged, preconfigured, and customizable solutions for solar developers, EPC providers, and energy asset owners who expect precision, performance, and long-term durability.

Engineered for Code Compliance and Long-Term Output

Our systems are compatible with leading inverter and racking platforms, reducing friction during site design and procurement. Each SEG solar switchboard is designed to:

Manage DC to AC transition with inverter integration
Coordinate rapid shutdown per NEC 690 and 705 requirements
Provide revenue-grade monitoring and energy metering
Enable utility backfeed, net metering, and protective relaying
Interface with battery storage and microgrid components
Meet environmental exposure demands for outdoor operation

Industrial electrical control panels in modern facility.

Meet Technical Standards

Available in voltage classes from 120 to 800 V and amperages up to 6000 A, SEG solar switchboards meet or exceed standards:

UL 891
NEC 690 and 705 rapid shutdown and backfeed protection
IEEE 1547 requirements for grid tied systems
NEMA 3R enclosures for rooftop or ground mount environments
Optional stainless steel enclosures for non-corrosive environments
Utility interconnection specs for voltage, frequency, and protection
Optional seismic and hurricane rated construction
