Just simple, transparent pricing that makes solar storage accessible to every homeowner.
Earn more from your solar production
Base pays you 3¢/kWh + real-time wholesale electricity rates for your excess solar production, with credits applied to your entire billânot just delivery fees. Combine that with lower base energy rates and no hidden fees, and you get more value from your solar investment.
Plus, as a Base member, you get reliable backup power during outages.
No, you donât need solar to use our batteries. You donât need solar to use Base because the batteries are designed to store energy directly from the grid. This allows you to access reliable backup power and lower energy costs without relying on solar panels.
That said, if you already have solar, Base works seamlessly with it. Plus, you can always add solar laterâour batteries are designed to easily integrate with solar systems. And Base offers competitive solar buyback prices.

Yes! Base works for you with or without solar.
Base batteries integrate seamlessly with solar panels without affecting your warranty or requiring any rewiring of your system.
Solar households choose Base for three key reasons:
- Power during outages: Your home stays powered even when the grid goes down.
- Extended outage protection: Your solar panels can continue recharging your battery during an outage, providing longer backup time.
- Competitive solar buyback: Base credits you for all your solar overproductionâwhether it charges the battery or goes back to the gridâat a rate of 3¢/kWh + a real-time wholesale price bonus .
If you donât have solar yet but plan to install it later, you can start with a Base battery now. When youâre ready, Base will integrate your solar panels by putting current transformers (CTs) on your battery.
Please coordinate with the Base support team to schedule this.
Base credits you for all of your solar overproduction each month. You can see your solar data on your monthly bill in the âSolar Creditsâ section.
On your bill, our buyback rate is 3 cents plus a bonus of the real-time wholesale (RTW) price for solar.
Your Solar Credit amount is the rate multiplied by your kWh of unused solar. Underneath the credits, we also list your homeâs solar usage (âSolar usage by homeâ) so you can see your usage alongside your overproduction.
If your bill is negative, Base rolls over your credits to the following month.
Yes. Base integrates with most solar panels to help extend backup duration.
However, automatic standby generators currently do not qualify for integration.
Yes! Base members have two ways to use a portable generator alongside their battery system:
Available Now
Members can connect a portable generator to their home by installing a generator interlock on their main electrical panel. Learn more here on how this works.
- This setup allows the generator to power your home during a prolonged outage if the Base battery is fully drained.
- Note: This setup does not recharge the battery â it only powers the home directly.
Coming Fall 2025
Base is launching a new version of the battery with an optional generator integration add-on (available for an additional $1,000). Learn more here on how this works.
- This add-on allows a portable generator to plug directly into the battery, unlocking deeper backup functionality.
This feature cannot be retrofitted to existing batteriesâmembers must wait for the new version of the battery if they want this capability.
Benefits of the Upcoming Integration
- Recharge the Base battery using a generator
- Power your home and recharge the battery at the same time
- Smarter load management between generator and battery
- Extended backup coverage â ideal for homes using under 75 kWh/day
Generator compatibility:
- Required: Portable generators with 240V output and L14-30 plug
- Not compatible: Whole-home standby generators
For any electrical work involving your main panel after your Base battery installation, the electrician can simply turn off the main panel as they normally would. There is no need to power down the battery or take any specific action related to it.
However, Base systems support a maximum of 200 amps. In most cases, Base cannot support upgrades above 200A, as they typically require splitting the panel, which would necessitate the de-installation of your Base system.

Base offers a significantly less expensive backup battery solution compared to alternatives due to the unique shared business model: Base earns income from the power grid instead of homeowners.
This business model allows you to get energy backup without paying tens of thousands of dollars for a traditional generator. An expensive solar system and solar battery also requires a massive upfront investment which often can take longer than the lifespan of the system to pay back. With Base, you pay just a one-time installation cost that pays the team of electricians to install the battery on your home.
Base offers fair, fixed rates and reliable backup power. Since revenue comes from the grid, not customers, Base avoids hidden fees and surprise rate hikes. Your agreement also legally guarantees your rates stay below the market average.

How long your Base battery lasts depends on four main factors:
- How much power you use: This is the most important factor. A battery stores a fixed amount of energy when the grid is down, so running high-usage devices (like A/C or laundry machines) will shorten backup time, just like a bigger water hose will drain a bucket more quickly. Reducing your power usage will extend it. We deploy larger batteries than the typical market size so that you can last longer.
- Battery charge at the start of an outage: Backup time depends on how charged your battery is when the power goes out. Base actively monitors charge levels, maintaining an average 93% charge over the course of a month. Our outage protection software tries to ensure that your battery has sufficient charge to las most outages, even though we sometimes lower it to 20% to perform our grid-balancing operations.
- How many batteries you have: Most homes get one battery (20-25 kWh), though some may qualify for two batteries (50 kWh). More batteries mean more backup power.
- Additional generation sources: Base batteries integrate with solar panels, which can extend your backup duration during an outage.
We calculate backup duration based on your battery's charge level and capacity. The high range shows backup time 90% of the time, while the low range reflects a 10% chance of a lower charge during an outage. Backup time wonât go below the low range unless appliance usage increases.
Here is a breakdown of how energy usage translates to battery duration:
- Low usage (e.g., fridge, freezer, and lights):
- Single battery: 30â40 hours
- Two batteries: 60â81 hours
- Average usage (typical appliances, some A/C):
- Single battery: 10â13 hours
- Two batteries: 20â27 hours
- High usage (heavy appliances like A/C or electric heaters):
- Single battery: 2â3 hours
- Two batteries: 4â5 hours
When your power goes out, weâll notify you and monitor your batteryâs status. If itâs running low, weâll recommend turning off high-usage appliances to extend your backup time.Â
