Took 2 hours from 29%. Hooked it up and it runs flawlessly. Powers my well and barely breaks a sweat. This will be for our short power outages we have every couple months for around 4 hours at a time. Anything longer and I’ll charge them with a small inverter generator. So far I really like them. Haven’t hooked solar panels to them but I think they’ll do well. Review: House power back-up - Wanted a second way to keep the power on in case of a power outage and these units fit the bill.

Took 2 hours from 29%. Hooked it up and it runs flawlessly. Powers my well and barely breaks a sweat. This will be for our short power outages we have every couple months for around 4 hours at a time. Anything longer and I’ll charge them with a small inverter generator. So far I really like them. Haven’t hooked solar panels to them but I think they’ll do well. ### ⭐⭐⭐⭐⭐ House power back-up *by A***R on August 6, 2024* Wanted a second way to keep the power on in case of a power outage and these units fit the bill. Great product. ### ⭐⭐⭐ Hub only works if you use the smart app *by H***F on January 3, 2025* When my Hub wouldn't turn on, they said I would need the app to update the Pro3s' firmware. Not being smart-stuff inclined (and not trusting that the update wouldn't introduce more glitches), I declined and shipped the hub back and got a bare-bones refund for it. I'm keeping the Pro3s, which are doing fine. I suspect the Hub was designed for the Ultra and they figured they could get it to work for the older Pro3s by means of a firmware update. But nothing in this 3-part bundle's description indicates the Hub won't work right out of the box. It won't (in my experience). ## Frequently Bought Together - EF ECOFLOW 8kWh Home Battery Backup: 2 DELTA Pro 3 with 50 Amp Hub, 120/240V 8000W AC Output, Solar Generator for Home Use, Camping Accessories, Emergencies, Power Outages, RVs - EF ECOFLOW 400W Portable Solar Panel, Foldable & Durable, Complete with an Adjustable Kickstand Case, Waterproof IP68 for Outdoor Adventures --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/638080480-8kwh-home-battery-backup-2-delta-pro-3-with-50](https://www.desertcart.is/products/638080480-8kwh-home-battery-backup-2-delta-pro-3-with-50) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-06-24*
