Style: DELTA 2 Max+220W Solar Panel
I've read a LOT of reviews, watched a LOT of Youtube videos and had given the purchase of a solar generator (actually, it's just a big rechargeable battery) a LOT of thought. I won't go into all the specs and technical junk since a lot of the other reviewers have done all that. I will just try and briefly discuss What I think about it. I spent around $1,700 for it but that included a big 200 watt solar panel. I see now that the whole package has even gone down a couple hundred dollars to around $1.500 but I still think I got a pretty good deal. I'm a 66 year old female and though both the battery and solar panels are heavy, I can still move them to where I want them. It's summer time here in the Deep South so I laid the solar panel flat on the ground where strong sunlight could shine on it. I had to move the battery fairly close to the panels since the connection cords are only so long, however I set it on a garden stand up off the ground and covered it with a white reflective towel to keep it from getting hot. The color of the battery is dark grey and will absorb a lot of heat if left out uncovered. And for crying out loud, don't forget about it and leave it out in the rain, or it will be ruined. My battery was at 38% charge when unpacked from the box it was shipped in. After 2 days of being charged by the solar panel (and with adjustments made for the movement of the earth and sun) it got to 76% charge. I like having the option to charge it by use of solar panels (and you can connect 2 of them at the same time but I only used the one it came with), but I hope I don't have to use them very often, since it's not a very efficient way to charge it. I charged it the rest of the way to 100% using a household outlet. I chose this particular solar generator (battery) because of the many high reviews, the price, and an output of 2400 watts will power a LOT of things such as refrigerators, freezers, a washing machine, coffee pots, microwave and all the smaller electronics and crap one thinks they'll need if the power should go off for several days. BUT!!! It won't power big appliances for more than 2 or 3 days before needing recharging. That's where the gas generator really comes in handy. It can be used just long enough to recharge the solar battery then shut off to save gas. That's my plan anyway if it should come to it. I think having both a solar generator and a gas/propane generator is the best way to do it as long as you have enough fuel. I connected my now fully charged solar battery to a mini fridge and it stayed nice and cold for 3 days until I disconnected the fridge and plugged it back into a regular outlet. I learned that if you're going to store the battery long term, that it needs to be at 50% or slightly less of a charge to keep the battery safe from self-damage. I don't know the details about why it needs to be at a lower charge, but whatever. The digital readouts are easy to see, it can be connected by an app to your phone, which would be nice in case you needed to see how things were going at the ol' homestead while you were out foraging for berries and non-poisonous mushrooms. But wait! If there's been an EMP then nothing will work anywa................! I suggest learning how to build a Faraday cage and storing your expensive battery in it when it's not needed. The solar panels are huge. Good luck figuring out how to keep them from getting melted if the bombs fall or the sun belches out a big one in our direction. But, you can only do what you can do...... So far, I really like my big battery. I have absolutely nothing negative to say about it. If it should fail for some reason I will be here to update this review even before you hear the sonic boom I created getting here. Oh yeah! I forgot to mention shipping. The battery took about a week after ordering to arrive and it was very well packaged. The solar panel was shipped separately and took about another week (two weeks after initial order) to arrive in very good condition. I chose to purchase it through Amazon because I'm very familiar with Amazon and it was several hundred dollars cheaper than if I bought it directly from Ecoflow. And shipping is free with Prime.

Style: DELTA 2 Max+220W Solar Panel
This battery bank is awesome. Right off the bat, my first impression is that EcoFlow really sets the standard for portable power generators—from the battery itself to the solar panel. Everything was extremely well packaged, almost like opening a Louis Vuitton purse. I charged the battery to 100% and did a full test run to prepare for Edison shutdowns. Edison has been doing two or three 8-hour shutdowns per week to upgrade the grid in my neighborhood. I have a saltwater reef tank, so keeping it running is absolutely critical. During my initial test, I ran everything except the heater and chiller, and the system consistently pulled about 280 watts. After 6 hours, the battery was still running with a little over 20% remaining. That lines up perfectly with the advertised 2048 watt-hours (280W × 6 hours = 1680Wh). My plan is to run the tank while I’m at work. As long as the unit is plugged in, it will top itself off while in use. When Edison shuts down, I should get around 7 hours of runtime. If power comes back intermittently, the unit will continue charging without any interruption to the tank. I tested it under load while charging, and it was pulling 1600 watts—so outages with brief restorations aren’t an issue at all. I also camp, which is another reason I chose a higher-end unit. Since California has been rainy and overcast, I tested the solar panel under poor conditions. Even with complete cloud coverage, the battery was still receiving about 20 watts. For comparison, I set up my 100W GOLABS panel at the same time, and it registered 0 watts. I can’t wait to see what the EcoFlow panel does in partial or full sunlight. I have three kids, and with my old 500-watt unit it was a constant battle over who got to charge their devices. This unit completely solves that problem. It has four USB-A ports (two of them fast charge), two USB-C ports, six 120V outlets, a cigarette lighter socket, and two small accessory jacks on the back. Once everything is fully established, I plan to use this setup to offset some utility costs for my fish tank. With a second solar panel (it has two input ports) and a timer on the charging outlet to turn on halfway through the night, I should be able to run the tank overnight on battery power and use solar during the day. Overall, this unit exceeded my expectations and gives me peace of mind for outages, camping, and everyday use.
