When the grid fails or you're otherwise left without power, what's your backup plan?

Even a standard generator has its limits. Key life-savers like heat sources, critical medical devices, and communication gear will fizzle out when your reserve dries up; that is, unless you're prepared in advance.

Enter the 2200XP Expansion Battery. It's a non-negotiable when amplifying your power supply and should always be part of your 2200 Solar Generator System setup.

  • TOUGH AS NAILS – Looks can be deceiving. Despite a sleek design and small size, this battery packs a wallop, and stacking them together means you can tap into even more power.
  • POWER YOUR WAY – Group up to seven of these batteries together and construct your power tower for emergencies. Connect them to your Grid Doctor 2200 and amplify your overall system’s capacity to a whopping 16,384 watt hours!
  • STACK THEM UP – These compact units stack seamlessly on top of your 2200 battery. Line them up in your bunker, tool shed, closet, or jam them in the back of your car.
  • CHARGE IN FOUR WAYS – Juice up the 2200XP from a wall socket, car adapter, solar panel, or directly through the Grid Doctor 2200. While it charges, use it to power your appliances and devices. Uninterrupted power is yours.
  • BUILT TO LAST – The sturdy lithium iron phosphate battery is good for over 3,000 cycles, offering a tough and cost-efficient power solution off the grid.
  • LEAVES NOTHING BEHIND – With multiple outlets, you can keep everything from your camping gear to kitchen appliances powered. It's even got your camper covered.
  • EXPERIENCE ULTRA-FAST CHARGING WITH 1800W POWER: Our advanced bilateral inverter technology outpaces traditional charge controllers, offering lightning-fast solar charging in just 3-4 hours, and even quicker wall charging in 2.4 hours. 

Currently, we do not ship Grid Doctor products to Canada.

    Utilizes the latest technology to charge your electric appliances in a fraction of the time that standard power sources take.


    Thanks to pass-thru charging, there’s no need to wait for a full battery. Charge the generator while you use it to power your electric appliances and keep your household running! This uninterrupted power supply allows you to keep essential electronics operational at all times.


    Charge up this battery by the sun, with an AC wall outlet, through a car adapter, or directly through the Grid Doctor 2200. That means whether your at-home power is out, you’re stranded inside your car, or you’re bugging out in the woods, power is possible! Charge virtually any appliance or device you own.

    (Do not use a GFCI outlet to charge the 2200XP battery.)


    Equipped with multiple power outlets, this powerhouse can practically power it all: kitchen appliances, power tools, ham radio mobile base stations, residential electric fences, and so much more. It can charge and run appliances in your home, inside your RV, and at your campsite.

    Having the ability to use your appliances and keep your household running smoothly as the battery charges is an underrated convenience in an emergency.

    You won't have to go without anything:

    • COMMUNICATION & INFORMATION – Keep phones, walkie-talkies, and other electronics charged to stay connected to family, friends, and emergency services. Plug in the radio, TV, or computer for breaking news, weather forecasts, and critical emergency information.
    • SAFETY – Keep the lights on to continue crucial tasks in the dark, as well as prevent accidents and other hazards.
    • MEDICAL TREATMENT – If someone in your survival circle relies on medical equipment that requires electricity, this uninterrupted power supply will be a literal lifesaver.
    • FOOD PRESERVATION – Prevent food from spoiling when connected to a refrigerator or freezer. Food is among your most precious resources, so you’ll want to save as much of it as you can!
    • FLEXIBILITY – Adapt to different situations. Use the generator as it charges from solar power during the day, then rely on stored energy at night.

    • SIMPLICITY – No juggling act needed. Charge and use the appliances you want, when you want.
    • EXTENDED BATTERY LIFE – Because the generator can be charged while in use, you’re less likely to deplete the battery. This extends the longevity of the unit.

    In addition to pass-thru charging capabilities, the 2200XP offers protected charging options. Maximum Power Point Tracking, or MPPT, protects you and your appliances in an emergency through efficient charging.

    Energy-efficient charging refuels faster, returning your appliances to full operational status sooner. Plus, the more efficient your energy use, the longer these essential electronics can run. Overall, energy efficiency reduces your dependence on unstable or unavailable power grids, making you more self-sufficient during disasters!
