Battery Energy Storage Systems for Homes
A battery backup can provide continuous power during blackouts, and reduce energy costs in some places.
A home battery backup system, also called a battery energy storage system (BESS) lasts for decades and can provide peace of mind by supplying instant, quiet backup power during outages. In places where utilities use time-of-use metering, battery backups can even lower your electric bill by charging the battery when rates are lowest for consumption at more expensive, peak rate times.
Cromwell’s certified, licensed electricians can install a battery energy storage system for your home, where it can be paired with solar panels, or simply powered by the grid. Either way, homeowners opting for a BESS get peace of mind during blackouts, as well as potential utility savings that could help the system pay for itself over time.
Top Battery Energy Storage System Suppliers
FranklinWH
FranklinWH is our first choice for installing a BESS for homes. This California company is highly regarded in the industry for their home battery energy storage system because they combine whole-home backup capability with intelligent energy management that helps maximize savings and energy independence.
Perfect with or without solar and/or generator integration. FranklinWH offers an industry-leading 15-year warranty made for Midwestern weather, and is highly reliable. Their high power output allows homeowners to run large loads, including HVAC systems, without sacrificing performance during outages and the modular design makes it easy to expand storage capacity as energy needs grow, providing greater flexibility than many competing systems. FranklinWH also integrates perfectly with nearly all solar inverter and generator brands. In fact, Cromwell Electrical owners Aron and Sarah Cromwell have a FranklinWH backing up their own home.
Generac PWRcell
The Generac PWRcell battery features a modular design with capacities ranging from 9 kWh to 18 kWh per cabinet, allowing for scalability up to 36 kWh when multiple units are connected. The system delivers up to 9 kW of continuous power, making it one of the most powerful options available. Additionally, Generac offers an expanded PWRcell system including solar panels and inverters, giving you the option to integrate seamlessly into a solar panel system.
Enphase IQ Batteries
Enphase IQ Batteries are a great option for solar-panel-equipped homes with Enphase solar microinverters, but their batteries don’t play well with other inverter brands. With a 15 year warranty and a great continuous power output, Enphase is a good option for those already using their micros.
Tesla Powerwall
Compared with many competing home battery brands, the Tesla Powerwall 3 offers a higher continuous power output in a single unit, allowing it to run more household appliances simultaneously without requiring multiple batteries. Its seamless integration with the Tesla ecosystem makes it a good choice for those with Tesla EVs.
We have found the FranklinWH is the most reliable home battery energy storage system available.
Advantages of a battery Energy Storage system (BESS) for a Home
1. Backup Power & Home Resilience
A BESS keeps your home running when the grid goes down.
Powers essentials like lights, fridge, Wi‑Fi, medical devices, sump pumps.
Avoids the noise, fumes, and maintenance of gas generators.
Instant, automatic switchover during outages—no manual start and no delay.
Due to Midwestern storms and our aging grid infrastructure (maxed out with data centers) Kansas, Missouri, and Nebraska see frequent outages. This is often the #1 reason homeowners invest in batteries.
2. Lower Energy Bills
A BESS can strategically charge and discharge to reduce costs:
Time‑of‑use savings: A pricing strategy that charges more for power during peak times, like during the day, and less during slower periods, like overnight. Home batteries allow you to charge overnight when power is cheap and use it during the day, avoiding buying power at peak times.
Solar optimization: If you don’t have net-metering, you can store excess solar instead of sending it to the grid at low credit rates.
3. Environmental Benefits
A BESS helps reduce carbon footprint:
Off-peak power is not just cheaper, it’s the cleanest power from the utility.
Reduces reliance on fossil‑fuel peaker plants.
Supports a cleaner, more stable grid.
A Battery Energy Storage System automatically detects a grid outage, responding so fast that you likely will have no idea you’ve switched over to battery power. Cromwell has years of experience integrating BESS with solar and generators, and even if you’re not ready for the full trifecta (solar/battery/generator) today our expert installation allows for it in the future.
Cromwell Electrical has over four decades of experience with BESS and offers professional, turn-key battery energy storage system design and installation services nationwide for commercial and industrial clients.
