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 — it only powers the home directly.
Coming Summer 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 batteries—members 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 — ideal for homes using under 75 kWh/day
