I plan to use this to run a few of the most important items in my house during a power outage. Between the solar panels and my Honda eu2200i, I can keep a charge on it even during an extended outage. Since the unit is portable, albeit heavy, I can take it anywhere I need quiet, clean power.
Special thanks to EcoFlow for offering such a great deal on the Delta Pro 3 and 400W portable solar station. I've been wanting to develop battery backup/solar capabilities for a while but haven't been able to afford a complete starter system until this great sale. I plan to purchase an add-on battery in the next few months.
The Delta Pro 3 is easy to set up, connect to your WiFi, update, and configure the app. I shut my house down and even back fed most 120v requirements for about 6 hours and still had more time on battery power if needed. I haven't attached the solar panel yet to see the affect and charge times. Overall, in very satisfied with the initial test.
I bought it about a month ago. I received the my station and solar panels together. This is A1.

Backup power and peak shaving!

I had a very long run 50A generator inlet box with manual transfer switch installed a few years back during rolling blackouts before later deciding that I’d prefer a quieter easier to manage LFP battery generator. After lots of analysis paralysis, I circled back to the DP3 purchasing a dual units with 50A hub package during a sale. I routinely use the DP3’s for peak shaving and supplemental off-grid power after getting roof mounted solar. I enjoy days using 100% self-generated power.
I’m happy that the DELTA Pro 3 works exactly as advertised. The only difficulty I encountered was when using it at night in my camper i had to get a flashlight to see the buttons and the ports. A backlight to the ports and buttons would have made it easier to use.
I wanted something to run my pellet stove in outages and had searched for some time. This unit surpasses my hopes. Unobtrusive, looks fine in the living room and does everything advertised and worry free safety wise. It will run my pellet insert for nearly 4 days with additional outlets for anything else such as critical items like the coffee pot. Excellent quality and well thought through like being able to make all adjustments off my phone. Well done EcoFlow.
