Installation & Hardware
Yes - Spec sheets
Our system offers 20-50 kWh capacity with an 11 kW inverter, making it one of the largest home backup systems available. It is built to back up your entire home, covering more appliances than any other home backup solution.
The battery is also UL certified for safety, fire safety rated, and designed for outdoor installation with a 15-year lifespan.
You can review specs on our specs page.
The battery is placed outside your house near your meter. The right configuration depends on your home’s layout, energy needs, and space availability (see NEC requirements below).
We have 3 main battery configurations:
- Wall-mounted battery (20 kWh): 58.5" tall x 27.17" wide.
- Ground-mounted battery (25 kWh): (1) 4' tall cube with a 3'x3' base.
- Two ground mounted batteries (50 kWh): (2) 4' tall cubes with 3'x3' bases, 3' apart from each other.

Our team handles everything on installation day. You just need to be reachable by text in case we need to contact you. You don’t need to be home unless your main panel is in your garage.
Installation is an all-day process, starting as early as 8 a.m. and finishing as late as 6 p.m. Here’s what to expect:
- Material drop-off: Our team will drop off a pallet of materials in advance.
- Crew arrival: The installation crew will arrive between 8 a.m. and 10 a.m.
- Power disconnection: Prepare for a 1-2 hour window when power to your home will be temporarily turned off. This happens while we reconfigure your wiring to enable backup functionality.
- Cleanup: Base’s team will return later that day or the next morning to collect any leftover equipment and boxes.
After the installation, please login to your Base Dashboard and input your Wi-Fi network name and password. A permanent Wi-Fi connection is required for the battery to function properly.
Base offers three different system configurations. The right configuration depends on your home’s layout, energy needs, and space availability.
- Single Ground Mounted: A single-unit system is great for most homes. It’s mounted on the ground and fits into smaller outdoor areas.
- Double Ground Mounted: A two-unit system is great for homes with a lot of outdoor space and high energy needs.
- Wall Mounted: A single-unit system is best for houses with limited outdoor space. It’s mounted on a wall, either indoors or outdoors.

A soft-start is an electrical device that reduces the high surge of current when your A/C compressor starts up.
For some members, soft-starts are necessary to ensure their Base battery can back up the entire home during an outage. Whether a soft-start is required depends on the type of A/C unit you have.
Here’s why:
- When an A/C starts, there’s an initial electrical surge known as locked rotor amps (LRA).
- Older A/C units typically have higher surge levels, which can exceed the Base system’s capacity to handle these spikes.
- A soft-start helps temper this surge, making it compatible with the system.
If a soft-start is required for your A/C, Base will let you know during the intake process. Base’s HVAC partner will then schedule the installation as part of your setup—at no additional cost to you.
Safety is at the foundation of everything Base does. The Base battery system is UL certified, which is the gold standard of electrical systems safety for all home appliances. It is also fire safety rated. Base contracts certified, bonded, insured, and licensed electricians. They work under Base’s master electrician, who operates with license #476697.
In the unlikely event of a problem, we're prepared to work with you to handle it responsibly. Additionally, Base is in charge of all warranty and maintenance of the battery. Base has comprehensive general liability insurance to address any unforeseen incidents
- Space for Battery: Keep the Base battery system at least 3 feet from all windows, doors, and gas meter vent outlets, per safety codes (NFPA 855 & NFPA 54).
- Main Panel Placement: Main panels cannot be placed in closets, as they must stay away from flammable materials (NEC 240.24(D)).
- Meter Height: Meters must be installed no higher than 6 feet off the ground for safe access, as per local utility rules.
- Interlock for Portable Generators: If using a plug-in portable generator, install an interlock on the main panel to ensure safe operation (NEC 702.4(B)).
- Clear Space in Front of Meter and Main Panel: Maintain at least 30 x 36 inches of clear space in front of the meter and main panel for easy access and safety (NEC 110.26(A)(1)).
- Meter and Conduit Integrity: Ensure the meter and conduit are securely attached and undamaged to meet installation standards (NEC 110.12(B)).
If your home does not meet NEC standards, Base can help recommend a local electrician to assist with tasks like installing an interlock or relocating a main panel. Once your home meets code, you’re good to go.
Base batteries operate within ambient temperatures ranging from -10°C to 50°C (14°F to 122°F).
Each battery module is equipped with four temperature sensors that continuously monitor the temperature. Charging or discharging is automatically disabled if the batteries become too hot, effectively preventing overheating.
The batteries have been rigorously tested and have passed the internationally recognized UL9540A safety test. This ensures that, even if a single cell overheats beyond safe limits for any reason, the other cells and nearby walls remain protected from thermal damage.
