Love the way the controls and features of this power station are so comprehensive, with the modular aspect even, with the ability to add extra batteries and increase the watt-hours. The remote control App is awesome! Love the way you cannot only monitor the system, but control it from the app as well, from anywhere. Very versatile. Also love the feature of being able to use solar to charge the power station while at the same time running appliances with it. The only drawback is the weight of these things, which is to be expected with something that has so much power. This one is almost fifty pounds; I use a hand truck to move it around and save my back from hefting it.
Note Re: Operating Environment Based On Testing Of My Unit - Delta Max 2000 2016 KWH:
As rugged as this unit is, such as weather-proof etc., it is not designed to operate quite as well in temps of 100 degrees or more for a long time. It has a fan that turns on automatically and helps to cool the power station, and the unit will definitely charge in 100 degree temps, but the heat will lower the rate of charge. Better charging efficiency is obtained when it's inside a cooled environment at around 88 degrees max. I noticed the unit charged very well at a good rate when inside & a max temp of around 88 degrees, but when being charged outside on the second day, when the unit is already warm from the previous day, and the temp reading about 91 degrees, the rate of charge was not nearly as good, reaching a maximum charge rate of about 50 watts during a four hour charging period, compared to charging at over 100 watts when inside and cooler. It still charges in the heat, but not nearly as much.
I bought a small condo three years ago and liked the fact that the condo complex is all electric, no gas, nothing to blow up, as we've all seen here and there. But as we also know electric is more costly, which is why it's nice to get such a lot of power from the sun for nothing, after the cost of the power pack and solar equipment.
So when I got my place I noticed the AC worked fine but was not really efficient being 18 years old, and the heating element for heat had burnt out long ago. So last year I had the entire HVAC system replaced with new central air AC and Heat. The AC is fabulous, quieter than the old unit, and more cost efficient as well. When cold weather came around I loved the new central air heating system, but quickly noticed it was very pricey to use. My electric bill jumped up a lot. So I started using an inexpensive oil/radiator type space heater that does a great job of heating my modest 500 sq foot place, and saves me a bunch of money. And now with my new power station and some solar panels the winter heating will cost even less.
This awesome power station is also great for emergencies. The power company here is very good, and if the power is out, they are on top of it and have the power back on in an hour or two. But an hour or two can be a very long time without any AC or Heat. The power station takes care of warming the place up in the cold weather, as well as powers a couple big cooling fans for many hours when it's hot.
But as good as the power company is, there was a storm last summer where some people had their power out for a couple days instead of a couple hours. A power station like this would come in very handy in a mess like that.
And as far as the solar panels to be used with this power station, I'm sure there are a lot of good ones around, but like many newbies to solar, I found it best to stay away from the panels made for charging a car battery with a max of 25 watts, and having to be sent back for neglect of paying better attention to what is being ordered. My personal choice would be the ECOFLOW panels, that deliver an awesome power punch, as well as having nice features for portability, and they are not paying me to say that. I have one of the 160-watt ECOFLOW panels that way outperforms and 800-watt set of panels that max out at 25 watts. And also adding a second 220 watt solar panel to provide a total of 380 watts.
After using this power station for a couple weeks or so, there was an issue or two that came up. I noticed that I got great power from the 160 watt solar panel, and even more power when I added another 220 watt panel, about 260 watts at peak, which seems pretty good. Then about the third day I was charging from the solar panels I noticed on the Power Station display screen, as well as the read out from my phone, something strange. It showed that the input source was a car battery, when I clearly knew it was from the solar panels, and the amount of power coming in, rather than around 200 watts or so, was only 45-50 watts.
I phoned tech support about this, they asked me if I had the latest firmware update, which I did. Then they said, as a solution, remove the input power source, turn the power off and leave it off for at least an hour. Turn it back on after an hour, which I did and saw the problem was resolved. Tech Support said that if this continued to happen, let them know and they would look at other solutions to the problem. It did happen only once more then was fine. I could be wrong but suspect the problem could be due to not allowing the power station to discharge enough, before charging it back up. At least that what I understand from other sources that mention how to keep a lithium ion battery healthy. So I make sure to let the battery discharge to almost empty before charging it back up.
Another problem happened, which was the ECOFLOW phone app showing that the power station was not on, and disconnected. But I could see clearly that the power station actually was on. Then I looked at the display screen on the power station and noticed the little white wireless icon was not showing. So I turned the unit off for just a minute or so, turned it back on, and could see the little wireless icon showing, at which point the app on my phone was working correctly, showing that the power station was on etc.
