STACK & EXPAND YOUR POWER SUPPLY BEYOND 3300 WATT HOURS

The Grid Doctor 3300XP Expansion Battery is a high-capacity, stackable battery that expands the power of your Grid Doctor 2200 Solar Generator System and Grid Doctor 3300 Solar Generation System. It lets you run your electrical appliances far longer—like having extra fuel to run a gas generator.

You can add up to seven 3300-watt expansion battery units for a combined output of 16,384 watt hours (Wh).

Double the run time of your Grid Doctor 2200 or 3300 Solar Generator Systems with every 3300XP you add!

PACKS A POWERFUL PUNCH – Don’t be fooled by the sleek appearance and smaller size. This expansion battery provides 2048Wh—far more than many other expansion batteries!

CREATE A 16,384Wh “POWER TOWER” – Stack up to seven of these expansion batteries to build up your own “power tower” for emergencies. Connect them to your Grid Doctor 3300 Solar Generator System to skyrocket your overall power capacity.

STACK THEM HIGH – Compact and stackable, you can place multiple 3300XP batteries right on top of your Grid Doctor 3300 Solar Generator System’s battery. Stack them high in the basement, shed, closet, or even inside the trunk of your car.

THREE WAYS TO CHARGE

Connect the 3300XP to a car adapter, our 200W solar panels, or the Grid Doctor 3300 Solar Generator System’s battery to charge whether you’re at home, on the road, or outdoors.

NOTE: Do not use a GFCI outlet to charge the 3300XP battery.

DOUBLE YOUR RUN-TIME WITH EVERY 3300 XP 

The math couldn’t be simpler: each 3300XP battery you add to your Grid Doctor 3300 Solar Generator System adds another 2,048 watt hours to the overall run-time. With the ability to add up to seven XPs, that power adds up fast.

KEEP THINGS RUNNING SMOOTHLY AT HOME OR AT CAMP

Here’s a quick look at what each Grid Doctor 3300XP unit can help you run longer, whether you’re inside or outside:

• All your kitchen gadgets, from the coffee pot to the microwave
• Your fridge and a freezer
• The washing machine
• Window AC units and box fans
• Your TV, computer, and phone
• HAM radios for emergency communication
• Your wi-fi router
• Life-saving medical equipment
• Power tools for quick fixes and projects
• LED lights and lights with motion sensors
• Electric fences for enhanced security

MODULAR UNITS: POWER YOUR WHOLE HOUSE AT ONCE

Each Grid Doctor 3300XP delivers power where and when you need it. Charge a stack of XPs together, then distribute them to power multiple areas.

• In a blackout? Power up the units together, then allocate them to different rooms. Light up the living room, keep the kitchen fridge cold, and heat a bedroom—all at once.*
• Bugging out in a group? Charge XPs together by day, then assign one to each tent for evening use. Lights, heaters, and more stay on through the night.

The possibilities are exciting and endless!

*The 3300XP Expansion Battery Unit contains only “DC-Out” ports. It will run devices (not included) with “cigarette lighter plugs” (12V adapters) or USB-A and USB-C plugs (like most cell phones). It can also run AC devices using an inverter adapter.

CHARGES FAST

Charges your Grid Doctor 3300 XP batteries at a rapid 1800W (when charged with the Grid Doctor 3300 generator), significantly outperforming comparable solar generators that max out at just 480W.

DOUBLE DUTY

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.
