Goal Zero 3900Wh Home Backup System V3 – Yeti 1500X + Home Integration Kit + 4 Tank Expansion Batteries + Link Module (~6,300Wh) Whole-Home Energy Kit

Installed the Home Integration Kit with an electrician over a weekend and it has been flawless. Four Tanks plus the 1500X give us around 6,300Wh, which ran our fridge, furnace fan, lights, router, and even the microwave during a 6-hour outage. The Link Module keeps everything balanced and the app monitoring is genuinely useful. Best money I've spent on the house.

We lose power several times a winter and this system has handled every one. Fridge, freezer, sump pump, and a few lamps ran all night without a hiccup. Swappable Tank batteries were the deciding factor for me over a gas generator.

The hardware is excellent and the transfer switch integration is clean. Just know you'll likely need an electrician unless you're very comfortable with electrical work. Once set up, it performs exactly as advertised.

Caught this on sale and jumped. Compared to a standby generator install, this was cheaper, silent, zero fumes, and needs no maintenance. Charging from solar in the afternoon topped everything back up after our last outage.

Performance is good and the capacity is real. My only gripe is the physical weight of the Tanks — moving them into position was a two-person job. Docking and setup went smoothly otherwise.

Ran our whole essentials circuit through a 9-hour outage. Silent, simple, exactly what we needed.

My husband and I are in our sixties and didn't want to deal with pulling starter cords on a gas generator. This switches over automatically and we hardly notice outages anymore. The app is a little busy for us, but our son helped set favorites and now it just works. Very glad we bought it.

Started with just the 1500X two years ago and finally pulled the trigger on this full bundle. The Link Expansion Module makes the four Tanks behave like one big battery, and capacity math checks out close to the stated 6,300Wh. Ran the fridge, freezer, internet, TV, and CPAP through an overnight outage with 40% to spare. Recharging via solar was faster than expected. No regrets at all.

The system itself seems well built, but one Tank arrived with a cracked corner of the housing. Support is sending a replacement, though the process took a week of back and forth. Reserving judgment until the swap is done, but the unboxing experience was frustrating for a purchase this size.

I wanted silent backup for my home office and kitchen circuit and this delivers. The transfer switch is professional grade and the integration with the 1500X was straightforward for my electrician. Runtime during our last outage covered about 14 hours of mixed load. If you need whole-home AC for days, you'll want more capacity, but for essentials this is superb.
