Style: DELTA 2 Max+400W Solar Panel
I really like this EcoFlow generator. It is very easy to use and charges fast. The battery lasts a long time and works great when I need power. It feels strong and good quality. I use it at home and also for emergencies. I am very happy with this purchase and I recommend it.

Received the EcoFlow Delta 2 Max, 400w panel and solar extension cables days before hurricane Beryl (July 2024). It has been a huge relief and well worth the money! Today is our 4th day without electricity with temps in the mid 90s, heat advisory, heat index of 100 degrees and low to no wind. It's hot as hell! Unit arrived very well packaged and set up was very simple. The only negative comment regarding set up would be the solar panel case... the case is perfect for storage but flimsy when used as a stand. I made a stand out of gray pvc and it works great. About the generator... I plugged in the unit before the power outage and it fully charged in an hour. Display screen is bright and easy to read. The number of USB & AC outlets are extremely useful and it has outlets for 2 panels. Solar charing... there is a bit of a learning curve here and it has to be managed throughout the day. To get the best charge, the panel has to be adjusted throughout the day according to the sun position. I have been able to get over 300 watts for several hours on a sunny day. Watt usage... this is where you have to manage watts and the app is a battery saver!!! For example: During sunny midday I can get up to 309 watts coming in. With my 25 cu ft refrigerator, 1 oscillating fan and a TV plugged in, all of that has been using 220 watts. Banking more watts than what is being used! But, if I unplug the refrigerator (and not open it) for 4 hours the wattage usage drops to 100 (food stays cold). Banking even more watts! Managing the usage this way gets us through the day with 40% - 50% battery life at sunset. Unplugging the refrigerator for 4 hours overnight helps save watts until the sun comes up. Overall... I'm very happy with this product! So relieved that my grocery items are kept cool and I'm not out driving around looking for gas and ice! My only regret... not buying a small generator for use upstairs.

The main reason I bought the battery was to have a power backup due to the constant blackouts that occur here. As I learned, I realized that it not only serves as a backup battery but also supplies free energy (via the solar panels) to the areas with the most electricity consumption in my house (kitchen, laundry room, my office etc..., which is where we spend most of the day). It works as an inverter. While the two 575-watt panels recharge the battery at the two charging ports, the battery supplies voltage at the same time, and when the sun goes down, the consuming power without needing the grid electricity (using just the battery). This has reduced my consumption electricity bill by more than half. It's a super powerful device and really worth the investment. P.D it is really funny when the entire block is without power and just my home totally lighted, I really enjoy it when everyone turns their head and look like asking them self why this house has electricity? lol

I bought two units. One with 400 watt panel and one with 2 x 160 watt panels. First the unit - Compact battery and simple interface to manage the battery. The weight is around 50 lbs. Moveable but requires some strength or caution if doing by yourself. Accurate estimates for battery life. It powered my extra fridge for 14 hours (136 watt draw). It got a lot of usage during the power outages in So Cal (Jan '25). While it has only been a few weeks, I have been pleased. Second the panel - the 400 watt is cumbersome to set up. It is larger and heavier than I would expect and storage can be a bit of an issue. While the 160 panels are easier to setup and store, keep in mind that you need to have more footprint to charge than the single 400 panel. Two 160 watt panels require about 50% more width if they are setup side by side. My preference is the two 160 panels. Just easier to setup. If you have a combination of panels like I do then learn to how to setup the mixed panels correctly. Understand series vs parallel setup etc. Bottom line is that either panel performs well. Attached is a screen shot that show all three of my panels recharging together.

I'm a proponent at this point. The battery was on my front porch this morning when I woke up. The solar panels are supposed to arrive tomorrow. The system wasn't supposed to arrive for another week. So 5 starts off the bat for arriving early! This is super easy to use, simply plug it in to charge and press the power button. The battery has several outlets, to use them, press the ac output button and plug something in. The display provides consumption info so you can see how long the battery will last. I have a 32 inch 4k LG display, an LED monitor light, 15 inch OLED display, 16" MacBook Pro, wifi, and a tower fan all running. Battery is about 15 hours remaining. Without the fan running, it's a little over 20 hours. I received the solar panels a week early. I discharged the battery to 70% to test charging. I laid the panels flat outside, it wasn't the best Ange, but they were producing about 200w. This charged the battery in about 2.5 hours. The panels are a pain to deal with. But, it's a great option to have if the power goes out. I didn't buy the battery for this, it's just a test to make sure it all works well. So far, so good. The main use case is for outages. It was 113 F last Friday and the power went out until 1:30 in the morning. This will at least give us a fan for our room and some light. I'm pretty sure we can go several days this way while charging during the day.
