Base (with Generator Recharge Port) | Tranditional standby generator (like Generac or Kohler) | |
Upfront cost 24 - 48 hours (low energy usage) | $1,695 Base 25kWh system + Generator Recharge Port (beta) | $15,000+ Varies by kW, permits, site work, fuel hookup |
Ongoing cost / maintenance 24 - 48 hours (low energy usage) | Low upkeep Base handles battery service under membership | Regular service Engine maintenance + periodic checks; fuel costs during outages |
Install complexity 24 - 48 hours (low energy usage) | No fuel line needed Battery install + inlet; plug in a portable generator when needed | Fuel hookup + ATS Often NG/LP integration + automatic transfer switch. |
Power draw 24 - 48 hours (low energy usage) | 11.4kW on battery Battery covers peaks; keep average under 3kW for “infinite” backup | Higher continuous kW Sized to carry big loads continuously (model-dependent) |
Automatic 24 - 48 hours (low energy usage) | Automatic on battery For long outages: pull out generator, plug in, keep going | Fully automatic ATS starts generator and transfers power automatically |
Noise 24 - 48 hours (low energy usage) | Silent most outages Generator noise only when you choose to run it. | Engine noise audible constantly Noise whenever it’s carrying the home. |
Energy rate 24 - 48 hours (low energy usage) | Fixed, below-market average guaranteed | No guaranteed low energy rate Keep your current plan; pay fuel during outages. |
When the power’s out, thousands of Base members stay up and running.

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.
No, you don’t need solar to use our batteries. You don’t 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 later—our batteries are designed to easily integrate with solar systems. And Base offers competitive solar buyback prices.
