Standby Generator Installation and Repair in Charlottesville, VA
A standby generator’s value is decided during installation, months or years before the storm that proves it. The unit itself is a commodity; the transfer switch configuration, fuel supply sizing, placement, and commissioning are the craft. Robertson Electric installs and repairs standby generators in Charlottesville, VA and the surrounding counties, with the electrical, gas, and load-calculation work all performed in-house.
Selection and sizing, the decision of what to protect and how large a unit that requires, are covered on our home generator services page. Schedule with Robertson Electric by phone, online, or 24/7 chat, and get the project built to help you stay comfortable no matter what storms may bring.

Our Standby Generator Installation and Repair in Charlottesville, VA Services
The Installation, Step by Step
Placement comes first: a pad located to meet clearance requirements from openings, property lines, and combustibles, with drainage and service access considered. The automatic transfer switch is installed at the electrical service, wired to monitor utility power, start the generator on loss, and shift the selected circuits, then return and shut down when the grid stabilizes. The fuel supply, natural gas where utility service exists or propane across the rural counties, is run and sized by our licensed gas line services, and sizing is not a formality: a generator under load pulls fuel at rates an undersized line cannot deliver, which shows up as a unit that starts and then starves precisely when needed.
Commissioning closes the project: the system is tested under real transferred load, not just started, the weekly self-test is scheduled, and the homeowner walkthrough covers what the machine will do and when. Permits and inspections are handled throughout, the finished work is photographed, and the installation is backed by the 10-Year Worry-Free Warranty.
Generator Repair
The repair catalog is specific: units that fail their weekly self-test, crank without starting, start but refuse to transfer, or shut down under load. Causes concentrate in batteries, fuel supply problems, controller faults, and transfer switch issues, each testable in order. Because we hold both the electrical and gas licenses, the diagnosis covers the whole chain in one visit instead of two contractors disputing whose side the fault is on. Findings come with photos and prices before work begins.
Keeping It Ready
A standby unit runs a few minutes a week and must be ready for a few days without notice, a duty cycle that punishes neglect quietly. Annual service, with oil and filter changes, battery load testing, transfer exercise, and a documented loaded run, is the maintenance floor, and the Energy Savings Agreement through our maintenance plans keeps it scheduled with priority. Panel capacity and interconnection questions on older homes route to our circuit panel services.
