Yes, Base serves customers with and without solar. Base’s batteries are easy to integrate with solar panels, and the integration does not affect your warranty or require any rewiring of your solar system.

Base batteries protect customers from 97% of outages. Depending on household energy usage, outage protection can last from 6 to 24 hours. In the event of an outage, Base notifies customers of their expected battery duration, tips to extend their coverage, and a timeline for grid power restoration.

Base's hardware is UL certified, the “gold standard” of electrical systems safety for all home appliances, and 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. Base also has comprehensive general liability insurance to address any unforeseen incidents. In the unlikely event of a problem, we're prepared to work with you to handle it responsibly. Additionally, Base is in charge of warranty and maintenance.

Base offers a 20 kWh battery and an 11 kW inverter, making it one of the largest home backup systems on the market. Base’s batteries have a longer duration and can back up more appliances in your home than almost any other home backup solution. Base batteries are designed to last up to 15 years and withstand extreme temperatures. Base owns the battery and will manage the warranty and any necessary maintenance on the system.

No, you will only be charged for your home energy consumption and credited for all of your solar overproduction (if you have solar). Base tracks the energy pulled from the battery separately from your home’s energy consumption, ensuring that you are only billed for your home’s energy use. The battery credit on your bill will reflect the amount Base credits back to you for charging the battery.

You will be billed automatically every month. You can track energy usage and view past bills through the Base customer web app. Base calculates electricity bills after receiving customer smart meter data and applying any credits (e.g., battery charging, solar buyback, early termination fees). Your first bill may take up to 35 days after starting service. All Base customers are automatically enrolled in autopay and paperless billing.

Base offers a fixed rate plan for the energy that your home consumes. This means that you will pay a fixed dollar amount for each kilowatt-hour (kWh) of energy that you use. Base’s energy rates are often about 15% lower than local market averages from other retail energy providers. Base guarantees that its energy rates will stay below the local market average for as long as the Base battery system is installed on your home.

If your home stops using Base as its retail energy provider, then the battery system cannot function and Base can de-install the battery system from your home. This could incur a $250 deinstallation fee to cover the cost of an electrician coming to your home to remove the battery. Base would not charge this deinstallation fee if you’re canceling because (1) you’re moving after 5 years of having Base or (2) Base’s retail energy rates exceed the local market average upon renewal of your retail energy plan.

There are two separate Base agreements: the battery agreement and the retail energy provider agreement. Here’s what it means to sign up with Base:

1. Base will become your energy provider for the life of the battery and will renew your energy rates annually at a price below the market average.
2. Base can access the battery when necessary and handles maintenance and warranty issues. All applicable warranties from the installer and manufacturer are transferred to you.
3. If you move, you can transfer the agreement to the next homeowner at no cost to you or them.
4. Since Base is in beta, backup energy should not be used for life-critical devices and cannot be guaranteed.
5. You will incur fees if the battery is stolen or damaged.

Yes, the main thing to know is that the home must be enrolled in the Base retail energy provider for Base to work. If it is not, then Base might de-install the battery. If your rental agreement includes your renters controlling their own electric utility in their name, then please do the following: 

1. Instruct your renters to contact Base to enroll in the Base retail energy provider. (They will receive free outage protection and energy savings on every monthly power bill!)
2. Notify Base that you plan to rent the property. Base can send you a Continuous Service Agreement to ensure that the home is powered even during vacant periods between renters.

No! Base will be your energy provider and ensure your power is on when you move into your new home. When you enroll with Base, the Base team will coordinate with the local electric transmission and distribution utility to activate your electric service. All you need to do is enroll with Base!

Around when you close on your home, Base will contact you via email (and phone if preferred) to enroll you in the Base retail energy plan with service starting on your closing date. Base and Lennar will also coordinate to have your energy storage system installed and operational before you close.

When the grid is up and running, the Base battery helps balance the grid through grid stability operations. This includes charging and discharging the battery at select times based on whether or not the grid is strained. Base gets paid by the grid for these grid stability operations. Homeowners don’t have to worry about this because Base’s retail energy provider charges a low, fixed rate for each unit of energy that the home consumes.
