Backup Power Systems

Generator or battery backup designed around your actual outages.

What the job involves

Generator or battery backup designed around your actual outages. There is a right way and a fast way to do this, and the fast way is what we end up removing on somebody else’s job a year later.

There is no mystery to it. It goes in this order. Code has moved on this more than once, so what was legal when the house was built is often not what goes back in today.

How we handle it

  • Load study to size the unit honestly
  • Transfer equipment that isolates from the utility
  • Clearances, pad, and exhaust handled to spec
  • Tested under load, not just started

Doing this in the White Mountains

Elevation and sun are hard on exterior equipment. Meter bases and outdoor gear age faster here than the catalog says.

Elevation, weather, and the age of the housing stock all change how this work goes here compared with a valley city. Equipment ages faster in this sun, monsoon surge is a real load on the system, and a lot of these houses were built as seasonal property and are now carrying full-time demand.

We do not upsell a panel when the problem is a loose neutral, and we do not patch a service that needs replacing.

Soft starts and other ways to shrink the load

There is a middle path between accepting a stalling generator and buying a much larger one. A soft start device ramps a motor up instead of throwing it across the line, which can cut the starting surge substantially on a well pump or an air conditioner.

Load shedding does the same job from the other direction. A relay that drops the water heater or the air handler the instant a larger motor calls lets a modest generator carry a house it could not otherwise handle, by making sure two big things never start together.

Both are worth pricing before you size up. The cost of either is usually far below the difference between one generator class and the next, and the smaller unit burns less fuel for every hour of every outage afterward.

Surge watts, running watts, and the well pump

Two numbers describe every generator and they are not close to each other. Running watts is what the unit sustains. Surge watts is the brief peak it can absorb while a motor starts, and motors draw several times their running current during that first fraction of a second.

This is why the well pump is the hard load in almost every rural backup system. A pump that runs at modest wattage can demand several times that to break away, and it does it from a standstill against a column of water.

A generator sized on running watts alone will start fine, carry the house fine, and then stall the first time the pump calls. Sizing the surge capacity around the largest motor, then adding the steady loads, is the order that produces a system that works.

Choosing a fuel out here

Fuel is the decision that shapes everything else about a backup system, and it is more settled by your property than by preference. Natural gas is the easiest to live with when the line is already at the house, because there is no tank to fill and no fuel to go stale. Plenty of properties in this territory do not have that line.

Propane is the usual answer here. It stores indefinitely without degrading, a buried or set tank holds days of runtime, and the same tank often already serves heat or cooking. The tradeoff is that a long outage in deep winter means arranging a delivery on a road that may be difficult.

Gasoline suits a portable unit and almost nothing else. It goes bad in months, it has to be stored somewhere, and refueling a running generator in a snowstorm at two in the morning is the part nobody pictures when they buy one.

What you get

  • Who shows upThe person who quoted it
  • PermitsHandled where the job needs them
  • AfterLabeled, documented, and cleaned up

Work gets left labeled and clean enough that the next electrician can read it.

Maintenance is the part people skip

A standby generator that has not run in two years will not start when you need it. These are engines, and engines that sit develop fuel problems, flat batteries, and seized components.

Most standby units self-exercise on a schedule, which handles the basics. It does not handle the battery, the oil, the filters, or the load test that proves it can actually carry what you expect it to carry.

An annual service and a genuine load test are the difference between owning a generator and owning a large metal box in the yard.

Questions we get

How often should it run?

Exercise it regularly and service it annually. A generator that sits for two years will not start in January.

Standby or portable?

A standby unit starts itself and needs no attention. A portable is cheaper and needs you to be home. An inlet and interlock makes a portable safe and convenient.

Why do I need a transfer switch?

It keeps your generator from backfeeding the utility lines. Without one you are putting power on lines that a lineman may be working on.

Do you clean up?

The work gets left labeled and clean enough that the next electrician can read what we did.

Will you explain what you found?

Always. You get told what the problem actually was, not just that it is handled.
