Generac generator vs a home battery: what Texas homeowners should know

The short version

A standby generator like Generac's 28 kW model burns gas to make power during an outage. A home battery stores energy and uses it during an outage and every night to lower your bill. Here's how a Generac 28 kW standby generator compares with up to 60 kWh of Duracell batteries through the Solrite program.

Our bias, up front: Watt Hero is an Authorized Solrite Dealer. Generac facts below come from Generac's own product page and warranty document; the installed price comes from a Texas Generac dealer. Check current terms before you buy either one.

kW vs kWh: they measure different things

kW is how much power something can deliver at once (a generator's size). kWh is how much energy is stored (a battery's size). A 28 kW generator and a 60 kWh battery aren't "28 vs 60" of the same thing: the generator can run as long as it has fuel, and the battery holds a set amount of energy that recharges from your solar or the grid.

What it means for a Texas home

Cost

A generator is a $13,700–$16,600+ purchase that only pays off during outages. The battery program is $0 upfront, and the battery works every day to shrink your bill.

Coverage

Generac's warranty is 5 years, with labor covered only for the first 2. Extended service has to be bought from a dealer, so ask exactly what it covers and for how long. Solrite covers service for the full 20-year term.

When a generator still makes sense

If you need to run a large home through a long, multi-day outage with no sun, a natural gas generator can keep going as long as gas flows. Some homes use both. Michael can talk through what your home actually needs.

Shopping a Generac package? Ask the dealer for the installed price in writing, the warranty schedule, what any service contract covers and for how many years, and the yearly maintenance cost. Then compare it with a Solrite estimate from your bill.
