Home Battery Backup and Solar Storage Installation in Denver

A home battery stores electricity so it can be used later.

Depending on the system, that electricity may come from solar panels or the electrical grid and may be used for backup power, solar self-consumption, energy management, or other household needs.

They often use similar battery technology, but the way the system is configured can differ.

A solar battery emphasizes storing electricity produced by solar panels. A backup battery emphasizes providing electricity during an outage.

Many modern systems perform both functions.

Not necessarily.

Certain home batteries can charge from the electrical grid even without rooftop solar.

However, without solar or another onsite power source, the battery cannot recharge from sunlight during a prolonged outage after its stored energy has been depleted.

Often, yes.

AC-coupled battery systems are specifically useful for many retrofit applications because they can integrate on the AC side of an existing solar system.

FranklinWH states that its current aPower 2 platform can integrate with existing solar systems without requiring replacement of the existing solar inverter in many applications.

Compatibility must still be evaluated for the specific equipment and electrical installation.

An AC-coupled battery has its own inverter and connects to the alternating-current side of the home electrical system.

This can make it easier to add energy storage to a home that already has solar because the existing solar inverter may be able to remain in place.

kWh, or kilowatt-hours, measures energy storage capacity.

It helps describe how much electricity the battery can store.

kW, or kilowatts, measures power output.

It describes how much electrical power the battery can provide at one time.

Both matter when sizing a home battery.

There is no single correct battery size for every house.

The answer depends on your electricity use, solar production, which appliances you want to operate during an outage, desired backup duration, and whether the battery can recharge during the outage.

A load evaluation is more useful than choosing capacity based only on home square footage.

Battery runtime depends on storage capacity and the amount of electricity being used.

A battery supporting a refrigerator, lights, Wi-Fi, and a few outlets will generally last much longer than the same battery operating central air conditioning, an electric water heater, electric cooking equipment, and other large loads.

Solar production may extend runtime if the system is designed to recharge from solar during an outage.

Some battery systems can be configured for whole-home backup, but that does not necessarily mean every appliance can operate simultaneously without limits.

Battery output, battery quantity, motor starting loads, electrical demand, and system configuration determine what can operate at one time.

Some properly sized battery systems can operate central air conditioning.

The design must account for both the AC’s normal operating power and the higher power required when the compressor starts.

FranklinWH’s current aPower 2 platform is designed for high household loads, but actual compatibility depends on the HVAC equipment and complete battery configuration.

Potentially.

The battery must be sized for the heat pump’s normal operating load, startup demand, supplemental heat, and the other electrical loads operating at the same time.

Cold-weather backup needs should be evaluated carefully because heating can consume substantial stored energy.

Technically, some configurations may support EV charging, but vehicle charging can consume a large amount of stored energy.

During an outage, many homeowners prioritize refrigeration, heating or cooling, lighting, communications, and other essential loads instead of using battery capacity for an EV.

Whole-home backup is a system configuration designed to keep a broad portion of the home’s electrical system powered when the utility grid fails.

System capacity, battery output, controls, and load management still determine how many large appliances can operate simultaneously.

Neither is automatically better.

A battery offers quiet operation, fast response, solar integration, and no need for routine fuel during battery operation.

A generator can potentially operate much longer if fuel remains available.

The best option depends on desired runtime, electrical loads, available fuel, solar, budget, maintenance preferences, and outage concerns.

Yes, with compatible equipment and a properly designed electrical system.

Some home-energy-management platforms can coordinate multiple power sources. The exact configuration depends on battery, generator, transfer equipment, electrical service, and manufacturer requirements.

FranklinWH is a home-energy-storage manufacturer offering battery and energy-management systems that integrate home loads with power sources such as solar, batteries, and the electrical grid.

Its current aPower 2 is an AC-coupled residential battery platform.

Cost depends on battery capacity, number of batteries, output requirements, backup configuration, existing solar equipment, electrical-panel work, installation location, controls, permitting, and utility requirements.

A whole-home system designed to operate large electrical loads generally costs more than a smaller essential-load backup system.
