Portable Generator Hookups & Battery Backup Installation in Northern Virginia

AJ Long Electric provides electrical hookup and integration work for compatible customer-owned or dealer-supplied portable generators and battery equipment. Equipment purchase, delivery, fuel systems, exhaust, pads, and engine service remain outside our scope.

The inlet is the connection point for a compatible portable generator cord. A transfer switch changes selected loads between utility and backup power. A listed interlock mechanically controls main and generator breaker positions on compatible equipment. We confirm which arrangement, if any, fits the panel, backup source, and local requirements.

We can evaluate the electrical integration for customer-selected, listed battery equipment. The supported circuits, transfer arrangement, manufacturer instructions, equipment location, and existing panel capacity determine the scope.

No. Our scope is limited to electrical panels, transfer equipment, inlet boxes, compatible battery connections, conductors, protection, testing, and related electrical coordination.

We review the running and starting requirements of the desired circuits against the continuous and surge ratings of the customer-selected source. High-demand loads may need to remain outside the backed-up group.

Requirements depend on the address, equipment, and hardwired scope. We confirm the electrical permit and inspection path before the project is scheduled.
