EF ECOFLOWSolar Generator DELTA 2 Max 2048Wh with 4X100W 12V Solar Panels, High Efficiency Monocrystalline PV Modules, 2400W LFP Portable Power Station, AC + Solar Fast Dual Charging For Camping RV

This was exactly what I needed for a small accessory dwelling we have an office setup in. It powers my office equipment all day including two monitors, and the solar panels keep the battery above 70% at all times. I seem to get about 275 watts from them when all four panels are plugged in on an 80 degree day. Even using a small 400 watt heater part of the time the battery runs my equipment all day long if I'm careful.

Where we live there are occasional power outages, not too often, we have a generac portable generator that we used in HURRICANE SANDY, we don’t have the budget for for a $12k plus standby system, so looking at the Ecoflow Delta 2 max seemed like a good option, got it on prime day deals with 4 100 watt solar panels, I have an interlock on my breaker panel so was easy to use, tried it after fully charging it, was able to power whatever circuits I wanted easily, fridge tv lights, between the solar panels, 12 v and 110 charging could probably run indefinitely, when no sun and no power, can start the portable generator for an hour to charge it, overall it’s a good solution, if anyone is worried about the gas generator, it’s 5 gallons so if needed running it an hour a day the 5 gallons would probably last more then a week, , and the Ecoflow is much easier to connect, no noise no fumes and can be used inside my house $1300 vs $12k is a nice option that works well for us

So far so good. I received the generator but not the solar panels. I send the vendor an email, via Amazon, to see if they shipped the solar panels separately. So I'm waiting for their response and my panels!UPDATE: A couple days later, I received the Solar Panels! Nice. Almost... I had to order wires that attached the Solar Panels to the Generator. A bit of a hoop jumping but overall I'm fine with the merchandise and service.Study up on Serial vs Parallel solar panels!Ray

All the lights are on on the front LCD screen. Yes - all. I called customer service and spent 30 minutes only to be told that they can't (or won't help). They said that they would take my e-mail address and communicate with me that way. It's been 24 hours - no communication. They told me to hold the power button for down for 10 seconds, that the Delta2Max would do a hard reset after an hour. Done - no change. Called them back - wasted more time. No help. The instruction manual is useless. The Ecoflow videos are all about selling - not about troubleshooting or how to use. I spent $5,000. Really aggravated...

Love my Ecoflow Delta 2 Max, with its LFP chemistry, and the Alternator Charger that I got with it as a package. Both have been nstalled in my self-built camper van for about 100 days, and have performed flawlessly.

I ordered during prime week and it was a great deal, unfortunately I ordered the hard panels not the foldable ones. Having no place to store them I requested a return. The staff was great with communication and we got it done today. Just waiting for the funds to hit my account and then I am reordering on Black Friday. Thanks ECO, great job.

it's a great product and does as described. I installed the alternator charger and it works perfectly. The Delta 2 Max is a little heavy but has the power that I needed.My only feedback is that the main outlets are on the back of the unit which can a bit challenging without moving it in and out of the storage spot. it would have been great to swap them with the usb ports for better usability. it's a nit but something to think about.

After the last power outage and the gas generator wouldn’t start this is all about peace of mind. Sump pump no problem, freezer no problem, frig no problem, CPAP no problem and knowing how simple it will be - priceless.
