A portable solar generator (power station + solar panels) is the fastest path to off-grid power in a tiny home. No electrician, no permits, no grid connection — just panels on the roof and a battery inside. The catch: undersizing your system means running out of power mid-day. Here's how to size it right and which units are worth the money.
How to Size Your Power Station
Add up the wattage of everything you'll run, multiply by hours per day, and that's your daily Wh (watt-hour) need. A well-insulated tiny home with efficient appliances typically needs 500–1500 Wh per day.
Typical tiny home daily power budget:
- 12V compressor fridge: 40W × 8h run time = 320 Wh
- LED lighting: 30W × 5h = 150 Wh
- Phone/laptop charging: 100 Wh
- Fans: 30W × 6h = 180 Wh
- Total baseline: ~750 Wh/day
Add cooking (Instant Pot ~1000W, 30 min = 500 Wh) and you're looking at 1,000–1,500 Wh per day for a comfortable setup. Size your power station at 1.5–2× your daily need to account for cloudy days.
Best Portable Power Stations for Tiny Homes
🏆 Best Overall: EcoFlow DELTA 2 — 1024Wh
The EcoFlow DELTA 2 is the best all-around portable power station for tiny home use. 1024Wh capacity handles a full day of baseline use. The X-Stream charging gets it from 0–80% in under an hour from wall power. Expandable with the DELTA 2 Extra Battery for 2048Wh total. Pairs with EcoFlow's 220W rigid solar panels for a complete off-grid system.
- 1024Wh — full day of baseline tiny home power
- 1800W AC output — runs most appliances
- 0–80% in 50 minutes via X-Stream
- Expandable to 2048Wh with add-on battery
- LFP (LiFePO4) battery — 3000+ cycle life
- App control and monitoring
Best Budget: Jackery Explorer 1000 Pro — 1002Wh
Jackery's Explorer 1000 Pro is the most-reviewed large capacity power station on Amazon. Slightly less output than the EcoFlow but often $100–200 cheaper. The SolarSaga 200W panels pair perfectly and the whole system is one of the most documented tiny home setups online. Solid choice if EcoFlow is out of budget.
- 1002Wh capacity
- 1000W AC output (2000W surge)
- Charges to 80% in 1.8 hours with 2× SolarSaga 200W
- Quiet operation — no fan noise at low loads
- Massive online community and documentation
Best for Full-Time Living: Bluetti AC200P — 2000Wh
If you're living in your tiny home full-time off-grid, 1000Wh fills up and runs out too fast. The Bluetti AC200P's 2000Wh capacity gives you genuine two-day autonomy on cloudy days — critical in Oklahoma where storm systems can block sun for 2–3 days. 2000W AC output runs a mini-split briefly, a full kitchen setup, and all your daily loads simultaneously.
- 2000Wh — two-day autonomy for baseline loads
- 2000W AC output — handles mini-split startup surge
- 700W solar input — pairs with 3–4 × 200W panels
- Multiple charging inputs simultaneously
- 17 output ports total
Best Solar Panels to Pair With Your Power Station
Best Rigid Panel: Renogy 200W 12V Monocrystalline Solar Panel
Renogy is the most trusted solar panel brand for DIY off-grid setups. The 200W mono panel is the best value per watt for tiny home roof installs. For a 1000Wh power station, 2× 200W panels (400W total) gives you a full recharge in 3–4 hours of good Oklahoma sun. For 2000Wh systems, run 3–4 panels.
- 200W output — best watt-per-dollar in the lineup
- Monocrystalline — highest efficiency in low light
- Pre-drilled mounting holes for roof install
- 25-year power output warranty
- Works with all major power stations via MC4 connector
Best Portable/Foldable: EcoFlow 220W Bifacial Solar Panel
If you don't want to permanently mount panels on your cabin roof, the EcoFlow 220W bifacial panel folds flat for storage and sets up in minutes. Bifacial design captures reflected light from the ground — 25% more output than standard panels in bright conditions. Perfect for cabin kits where you're not ready to commit to a permanent roof install.
- 220W bifacial — up to 25% more output
- Folds flat — no permanent roof mount needed
- Built-in kickstand for optimal angle
- IP68 waterproof rating
- Direct EcoFlow DELTA compatibility
Complete Off-Grid Starter System (Under $1,500)
- Jackery Explorer 1000 Pro — ~$700
- 2× Renogy 200W panels — ~$300
- Renogy 30A charge controller — ~$40
- MC4 cables and connectors — ~$30
- Total: ~$1,070 for a full working off-grid system
