Home Battery Backup questions from St. Peters
Do you handle the permit for home battery backup in St. Peters?
Yes. We pull the permit with the office that has jurisdiction at your address, St. Charles County or the City of St. Peters, and schedule the inspection. The permit is included in our quote.
Who is the utility for St. Peters homes?
St. Peters is served by Ameren Missouri or Cuivre River Electric Cooperative, depending on your address. When the work needs the power disconnected or a meter changed, we coordinate it with the utility for you.
Which parts of St. Peters do you serve?
All of St. Peters (63376, 63304) and the surrounding area, including O'Fallon, St. Charles, Cottleville, Weldon Spring.
Can a battery power my whole house?
Yes, with a whole-home system sized for it. The Anker SOLIX E10 with its Power Dock and EG4 FlexBOSS systems with the GridBOSS connect at your main panel and switch the whole house over automatically. How long it runs depends on battery size and what you run, so we size it to your loads, and solar extends it.
How much does whole-home battery backup cost?
A solar-ready whole-home battery system typically runs $10,000 to $20,000 installed. With solar, most projects run $20,000 to $35,000 or more. Every home is different, so the price depends on battery capacity, solar array size, your loads and any panel work. We quote it after a load review.
Anker SOLIX E10, X1 or EG4: which is right for me?
The E10 is Anker's newest whole-home system: 7.6 kW continuous per unit, up to 30 kWh per unit and expandable to 90 kWh, with a 200A Power Dock for automatic whole-home switchover. The X1 is modular, adding 5 kWh battery modules up to 30 kWh per system. EG4 FlexBOSS systems suit larger solar arrays and higher loads. We recommend one after a load review.
Do I need solar?
No. We install whole-home battery backup that is ready for solar, and you can add panels now or later. Solar recharges the batteries during a long outage and lowers your bills the rest of the year.
