Portable Power Station DELTA 3 Plus, 1024Wh LiFePO4 (LFP) Battery, 1800W AC/140W USB-C Output, Solar Generator (Solar Panel Optional) for Home Backup, Camping&RV

The EcoFlow Delta 3 Plus is, without exaggeration, one of those rare devices you wish you could rate six stars just to properly communicate how absurdly good it is. Most portable power stations feel like compromises—good at some things, mediocre at others, never quite earning total trust. The Delta 3 Plus is the opposite: it behaves like a fully grown UPS, a renewable energy appliance, and a field-grade generator all sharing the same chassis. And thanks to its 10ms switchover, it keeps networking racks online so smoothly you’ll have to check the logs to confirm the power even flickered. For small business racks, lab gear, or home network cores, it simply doesn’t flinch. That would already be enough to recommend it, but then EcoFlow wandered into “hold my beer” territory and added dual MPPT inputs that accept up to 1000W of solar. Actual, full-size house panels plug into this thing like it’s a pint-sized powerwall, and the result is borderline magical. You can run a firewall, switch, modem, controller, and accessories for 8+ hours straight… and then watch the Delta 3 Plus refill itself on solar faster than many UPS units recharge from AC. For anyone trying to build a cost-efficient hybrid UPS solution—or just wanting peace of mind without buying enterprise battery cabinets—this is the most practical and overachieving option available. The versatility is what seals its legendary status. In the rack, it’s a clean, quiet, LFP-based protector that outperforms most UPS units on stability and lifespan. On the job site, it runs tools, testers, laptops, APs, or anything you’d normally plug into a generator—minus the noise, fumes, or neighbors glaring at you. And once work is over, it becomes the ultimate camping battery, perfectly happy to run lights, induction cookers, or even a full-size microwave because yes, someone will try it. Fast charging makes it almost unfair, thermal control is dialed-in, and the whole device feels like it was engineered by people who decided portable power should be fun, not stressful. What makes the Delta 3 Plus such a “must own” device is how it quietly replaces multiple categories of equipment. It’s a UPS that lasts longer. A solar generator that charges faster. A portable battery that behaves like a home backup unit. A field tool that simply refuses to fail when everything else is having a bad day. It’s the one power solution that makes you immediately wonder how you ever worked—or camped—without it. If there’s a higher tier than “highly recommended,” this belongs in it. ⸻ Pros • 10ms switchover rivaling high-end UPS units • Two MPPT solar inputs supporting 1000W—works with house panels • LFP battery = safe, long-lived, cool-running chemistry • Powers a full SMB rack for 8+ hours with ease • Fast charging, quiet operation, incredibly stable inverter • Equally brilliant for racks, field work, camping, and off-grid setups • Feels like multiple devices replaced by one overachiever Cons • Heavy—portable power still means “you’re carrying power” • Overkill for anything smaller than a full rack or campsite • EcoFlow’s app occasionally wants to be the star of the show • You will absolutely end up wanting two

I've been working with solar and (solar) power stations for many years. From my homebrew whole house, to a number of portable models from different manufacturers. I've been a Bluetti guy for quite a bit of that time. They have been, and remain very good. This is my first Ecoflow. I LOVE this thing right out of the box. The features and app integration are outstanding. From the ability to control charge rates, to being able to control how much you top off and how low you deplete the battery(ies). I'm blown away. This has features not found on the bigger, super high end units out there. I've already ordered the extra 1 kwh battery and will probably pair it all up with the Smart Gen 3. Pros: Storm Guard (Warns you within 12 hrs of when bad weather might effect grid power so you can top up) Charge Rate Control Total charge control Depletion control Relatively light weigh Water and dust resistant (camping, outdoor use) Very good inverter efficiency, AC and DC (power being drawn) Outlet placement FAST charging, from grid and from solar QUIET. I mean amazingly QUIET. Ability to schedule tasks such and charging Ability to setup grid charging when electric rates are lowest. (The app interfaces with your power company for the info automatically) Makes my bed first thing in the morning without me asking. (Ok, maybe not that.) Cons: Only one, and hope it might be addressed in a firmware update. AC Idle/Phantom load is pretty ugly for this size unit. The DC is excellent, its only the AC side. But with the large inverter capacity for AC, it comes with the territory. My AC200MAX is not as efficient and the phantom load is about the same. I would whole heartedly recommend the Delta Pro 3. It will be going camping with me in the cold of January this year for sure. Oh, and shipping was super fast.
