Portable Generators & Battery Backup in Tysons, VA

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.

The equipment, electrical capacity, access, property layout, and local authority can change the scope from one Tysons address to another. AJ Long Electric confirms those conditions and the applicable coordination path before finalizing the proposal.

Cost depends on the equipment, electrical capacity, access, route, corrective work, and local coordination required at the property. AJ Long Electric provides a written estimate after the relevant conditions and project boundary are assessed.
