A home solar system with battery backup can keep a few essential circuits running when the grid goes down. Goal Zero’s home backup bundles combine a portable Yeti X power station, a manual transfer switch, and Boulder solar panels into one package. Instead of a permanently installed battery, these systems use a Reliance Pro/Tran 2 Series transfer switch that a licensed electrician wires to up to four circuits in your breaker panel.
The four kits below differ mainly in total watt-hour capacity and the number of expansion batteries included. All use the same 15-amp, four-circuit transfer switch and come with three 200-watt briefcase solar panels. Choosing comes down to how many circuits you want to back up and how long you need to run them between sunny days. For a closer look at how battery sizing works, see our guide to home battery capacity planning.
Every specification on this page comes from the manufacturer’s own product page, checked on 29 October 2026. We have not used these products ourselves, so the picks are based on published specifications only.
See our overview of grid-tied, hybrid, and off-grid systems to understand where portable backup kits fit into the bigger picture.
How we chose these
- Total capacity: More watt-hours means longer runtime for the same loads or the ability to support more circuits.
- Surge power handling: All kits share a 2,000W continuous and 3,500W surge inverter, which matters for starting motors like a fridge.
- Expansion battery count: The number of Yeti Tank batteries determines the step up in storage between bundles.
- Solar recharge: Each kit includes 600W of Boulder 200 Briefcase panels; actual recharge time depends on sun and the battery stack.
Goal Zero states the approximate backup duration for each kit, but your actual runtime depends on which circuits you select and how much power they draw.
Comparison table
| Product | Total Capacity | Power Station | Expansion Batteries | Solar Included | Transfer Switch |
|---|---|---|---|---|---|
| 3000Wh Kit | ~3,032Wh | Yeti 3000X | None | 3× Boulder 200 | Reliance 4-circuit |
| 5400Wh Kit | ~5,400Wh | Yeti 3000X | 2× Yeti Tank | 3× Boulder 200 | Reliance 4-circuit |
| 7800Wh Kit | ~7,800Wh | Yeti 3000X | 4× Yeti Tank | 3× Boulder 200 | Reliance 4-circuit |
| 10800Wh Kit | ~10,800Wh | Yeti 6000X | 4× Yeti Tank | 3× Boulder 200 | Reliance 4-circuit |
All four kits ship with the same 600-watt solar array. Goal Zero’s stated backup durations are estimates that depend on actual loads connected to the transfer switch.
1. Goal Zero 3000Wh Home Backup Solar Generator: for one-day backup of up to four circuits
Goal Zero describes this as a one-day backup system built around the Yeti 3000X with the Home Integration Kit.
The kit is rated for roughly 3,032 watt-hours and includes three Boulder 200 Briefcase solar panels, a combiner, and a 30-foot extension cable.
Goal Zero says the Yeti 3000X AC inverter delivers 2,000 watts continuous with 3,500-watt surge capacity to handle appliances like full-size refrigerators.
- No expansion batteries in this bundle (Goal Zero)
- Suggested circuits include fridge, garage door, living-area outlets, and light switches (Goal Zero)
- Battery type is lithium-ion with MPPT charge controller integrated into the Yeti 3000X (Goal Zero)
Pros: Simplest kit in the lineup; one-day backup for up to four essential circuits
Cons: Smallest capacity here at about 3,032Wh; no expansion batteries in the bundle

2. Goal Zero 5400Wh Home Backup Solar Generator: for 1.5-day backup with two expansion batteries
Goal Zero calls this a 1.5-day backup system with roughly 5,400 watt-hours of capacity.
The bundle adds the Link Expansion Module and a pair of Yeti Tank batteries to the Yeti 3000X and Home Integration Kit.
It includes the same three Boulder 200 Briefcase solar panels and a 30-foot extension cable as the smaller kit.
- Includes two Yeti Tank expansion batteries with Link Expansion Module (Goal Zero)
- Same 2,000W AC continuous and 3,500W surge inverter in the Yeti 3000X (Goal Zero)
- Transfer switch is a Reliance Pro/Tran 2 Series 15-amp, 4-circuit 120V model (Goal Zero)
Pros: Nearly double the capacity of the entry-level kit; expansion batteries pair neatly with the Yeti 3000X
Cons: Still limited to four transfer-switch circuits; expansion batteries add weight and floor space

3. Goal Zero 7800Wh Home Backup Solar Generator: for 2.5-day backup with four expansion batteries
Goal Zero describes this as a 2.5-day backup system providing roughly 7,800 watt-hours.
The kit uses the Yeti 3000X along with the Link Expansion Module and all four Yeti Tank add-on batteries.
Three Boulder 200 Briefcase panels, a combiner, and a 30-foot extension cable handle the solar recharge side.
- Four Yeti Tank expansion batteries included (Goal Zero)
- Yeti 3000X provides versatile ports including 60W USB-C Power Delivery, USB-A, regulated 12V, and two 120V AC ports (Goal Zero)
- Goal Zero says the integrated MPPT charge controller ensures efficient solar charging
Pros: About 7,800Wh, which Goal Zero calls a 2.5-day backup system
Cons: Same 2,000W inverter ceiling as the smaller kits; four tanks take more room

4. Goal Zero 10800Wh Home Backup Solar Generator: for 3.5-day backup with largest battery stack
Goal Zero bills this as a 3.5-day backup system with roughly 10,800 watt-hours of capacity.
It pairs the Yeti 6000X with the Link Expansion Module, four extra tank batteries, and the Home Integration Kit transfer switch.
The solar setup again consists of three Boulder 200 Briefcase panels, a combiner, and a 30-foot extension cable.
- Uses Yeti 6000X instead of Yeti 3000X; both share the 2,000W AC continuous and 3,500W surge inverter rating (Goal Zero)
- Four Yeti Tank expansion batteries included plus Link Expansion Module (Goal Zero)
- Yeti 6000X adds seven port options including two 120V AC, 60W USB-C, USB-A, and regulated 12V (Goal Zero)
Pros: Highest total watt-hours available in a single Goal Zero home backup kit; longer runtime per charge cycle for the same four circuits
Cons: Same 2,000W continuous AC rating as the Yeti 3000X kits; same 600W of included solar for a much larger battery bank

Which one fits you
| Your situation | Look at | Why |
|---|---|---|
| Short, occasional outages | 3000Wh kit | Goal Zero calls it a one-day backup system for a few essential circuits, with no expansion batteries. |
| Multi-day outages in a smaller home | 5400Wh or 7800Wh kit | The extra tank batteries stretch runtime to 1.5 or 2.5 days while keeping the same four-circuit transfer switch. |
| Longest possible runtime from a portable kit | 10800Wh kit | The Yeti 6000X with four tanks provides Goal Zero’s maximum bundled watt-hours for extended blackouts. |
Practical tips
- Have a licensed electrician install the manual transfer switch. Goal Zero specifies it is a Reliance Pro/Tran 2 Series four-circuit model, and the circuits you choose determine how long the battery lasts.
- Your actual runtime depends on the wattage the connected appliances draw. Goal Zero gives examples like a CPAP at 65 watts or a microwave at roughly 1,000 watts, so a circuit running a fridge and a few lights will deplete the battery differently than a circuit powering a microwave.
- Consider keeping one of the included Boulder panels positioned for morning sun and another for afternoon exposure to spread solar charging across the day and recharge the battery stack faster.
FAQ
Can I add more circuits to the transfer switch later?
No. The Home Integration Kit uses a four-circuit manual transfer switch. To back up additional circuits you would need a different approach than what these bundles provide.
Do these systems recharge from the grid when the power comes back?
Yes. Goal Zero states you can keep the Yeti charged via a wall outlet at home, and the system can recharge from solar during an outage.
What is the difference between the Yeti 3000X and Yeti 6000X?
Both have a 2,000-watt continuous AC inverter with 3,500-watt surge according to Goal Zero. The 6000X has higher internal battery capacity but the same port layout and inverter specs as the 3000X.
Can I run a well pump or central air conditioner with these kits?
Goal Zero does not list well pumps or central AC among suggested loads. The transfer switch supports 15-amp 120-volt circuits; large 240-volt appliances are not compatible with this transfer switch setup.
