Introducing the Base Generator Recharge Port
Built for the long outages Texans actually face — a new beta product that turns a standard portable generator into a whole-home generator.
Unlimited backup, made simple.
Base's Generator Recharge Port connects your portable generator directly to your Base battery — letting your system recharge and power your home automatically during an outage. No switches, no downtime, no $15K+ standby generator needed.
Whole-home outage protection for up to 95% less.
A fraction of the cost compared to a traditional standby generator or paying to have an interlock installed at your home.
Power that lasts as long as your fuel supply.
Your Base battery covers day-long outages automatically. For longer ones, you can now plug in a generator and extend your backup for days — no interruptions, no manual transfer.
Easy as 1, 2, 3.
Unlike interlocks or DIY setups, Base manages the transition between battery and generator seamlessly through its inverter, keeping voltage stable and your electronics safe.
How it works
During an outage, your Base battery powers the home automatically. Plug in a generator and it recharges while keeping power steady — no switches, no flicker.
Compatible generators
The Generator Recharge Port works with most 240-volt portable generators Texans already own. To confirm yours is compatible, check three key specs:
Output voltage: 240V
240V is what allows full-home backup. If your generator has a 240V outlet (often labeled “L14-30”), you're good to go.
Receptacle type: NEMA L14-30R
Look for a four-prong, twist-lock outlet labeled “L14-30R.” That's the connection the port uses.
Running wattage: 4000 W or higher
Your generator needs at least 4 kW of running power. Anything smaller won't work.
Don't own a generator yet? Here's what we recommend.
Two reliable, quiet, multi-fuel generators with 240V output and 4kW+ power for safe, steady recharge.
WEN DF680iX Quiet Portable Generator
WEN DF680iX: Very portable and easy to roll outside during an outage. Despite its small size, it can output up to 4.5kW on propane.

Champion Tri-Fuel Generator
Champion 9000 W Tri‑Fuel: We recommend this if you're considering natural gas operation. 6.5kW on propane, 5.9kW on natural gas.

We're happy to answer all your questions
Base is your energy provider and backup power provider in one.
We install a large battery (from 25 kWh to 50 kWh) at your home for a low upfront cost. You get power from us at competitive rates because our batteries help balance the grid — charging when demand is low and discharging when the grid needs support. When the power goes out, your battery automatically kicks in to keep your home running. Our current system protects against 97% of outages.
To get with Base, you pay a $50 refundable deposit upfront. This deposit applies toward your one-time installation cost once your battery is installed.
Installation Costs
- • Installation fee: $695 or $995 (varies by zip code and plan)
- • Your $50 deposit will be credited toward this fee
Ongoing Costs
Membership Fee — $19/mo or $29/mo, depending on your plan
Monthly Energy Bills — energy rate of 8¢/kWh plus your utility's transmission and delivery fees. If you have solar panels, Base buys back any excess energy you produce at 4¢/kWh.

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.
Your rights in a Texas HOA
Under Texas Property Code §202.010, homeowners in HOAs have the right to install “Solar Energy Devices” (as defined in Tax Code §171.107), which includes batteries like Base. Your HOA may regulate the location and appearance of the installation under its aesthetic guidelines. Because each HOA has its own review and approval process, we strongly encourage you to contact your HOA before scheduling installation to avoid delays, required changes, or potential violations.
Permits & location
Base manages all permitting creation, submission, and inspection with local cities and utilities. Hardware is installed near the electric meter along an exterior wall. No changes are made to the roof or front face of the home. You can read more about our electrical and spacing requirements that determine battery location here.
Specs
The specs for Base batteries can be found here:
Safety & certification
- • Hardware is certified to UL standards: the ‘gold standard' of electrical system safety. This means it has gone through a rigorous set of safety tests prior to being built, plus each individual system is tested prior to installation.
- • Our electricians are licensed, bonded, and insured. All electricians work under a Master Electrician.
- • Our batteries use Lithium Iron Phosphate technology, which is far safer than other batteries by design, including being much safer than the batteries in most EVs, phones, and laptops.
- • Base batteries have active fire suppressants built into them. If the battery detects a fault, airbags of fire suppressant pop inside the battery, significantly reducing the likelihood of a fire spreading if one were to start.
Yes! Base has a strong referral program. Base members are essential for spreading the word about Base and getting more neighborhoods involved.
Existing members can send friends, family, neighbors, or strangers their personal referral link, which you can access in your Base account.
Refer a friend and you both will receive a free month of power (up to $250) when their battery is installed. For members with solar, we swap the free month for a $150 bill credit — because lower bills shouldn't mean a small reward.
Base operates differently from traditional power companies. Instead of profiting directly from customers, Base earns revenue by using grid-balancing software paired with outage prediction technology. This approach optimizes the Base battery for both grid stability and outage protection.
When the grid is functioning, Base uses its batteries to support grid balancing. This strengthens the grid's resilience and generates income for Base. By leveraging its network of batteries for grid balancing, Base maintains low rates for members while remaining profitable.
