EF ECOFLOW Solar Generator DELTA Max (2000) 2016Wh with 220W Solar Panel, 6 X 2400W (5000W Surge) AC Outlets, Portable Power Station for Home Backup Outdoors Camping RV Emergency

So I used to have a 75 ft extension cord running out to my tool shed that plugged into a 20 amp generator inlet. I didn't want to deal with trenching and running a line so I figured I would experiment going off grid with this product and some solar panels. I will list the good and bad below with each issue I ran intoCharging the generator: I used 4x200 watt solar panels on the roof and ran them to the machine. One the best day so far I have gotten about 475 watts input on the solar panels and have two facing east and two facing west since I am looking for the longest input not the highest. It charges just fine without any issue. At dusk I can hear a relay clicking which I looked up and other users have reported it is the solar generator recognizing some minor input by the solar panels but not enough to click over the charging aspect. I hope there is no long term issues with the relayApp: The app is amazing and I love it. The garage gets very mild wifi but the generator is able to pick up on it. Set up is a breeze and I can control the outlets, run time, charge capacity etc from the app. It is very convenient.Power: The power is absolutely amazing. I have my garage hooked up with 6 Shop LED lights drawing about 300 watts and a fan on a seperate 15 amp circuit and a sump pump that is crucial for the drainage in the backyard + and any power tool you can imagine on a dedicated 20 amp circuit. The 20 amp I have a true HD 20 amp plug running into the inlet. I have turned on the lights, sump pump and air compressor all at once and this had no issue powering everything with zero start up lag. I turned the sump pump off and powered up the shop vac and measured the watts and was close to 1800 with the vac and compressor on. I am absolutely impressed with the power this thing can deliver and was super worried about it running these things however it shows no issue. I have faith it will power the table saw and miter saw without issue as both those machines draw a lower wattage and amps than what I experimented with.Run Time and Measurement issues: This is my biggest concern with this machine is I don't feel the battery capacity is a true 2kwh design. I have a "kill a watt" measurement tool and it is measuring my sump pump at 680 watts however this is measuring the same pump at almost 800 watts. That is a huge discrepancy and it seems like there is a markup of watts in anything it is running. For example my bug zapper on the kill a watt measures at approximately 60 watts but on the generator it is pulling 78 watts. It is almost like anything drawing current is marked up by almost 15-20%.Another major issue I have is the machines draw on itself while just sitting there. My shed has a constant draw of around 5 watts (measured with the kill a watt machine) when everything is off. This should mean that with nothing running I should still get roughly 16 days off the machine with nothing running. That isn't the case as it will run itself down in about 2.5 days without anything powered on. That means the generator itself is drawing a considerable amount of power just to keep itself on whether that is to keep it connected to wifi or keep the fan going etc. Not sure why but that just feels unnaceptable to me. I will go to bed and it will be at 100% and I will wake up and it will be at roughly 82%. That makes it really tough to be reliable in the winter when I am not getting a huge solar input. I am worried that it won't be able to keep up with the draw let alone power the sump pump and anything else needed during that time frame.I could get another battery to supplement this but you are limited to 800 watt solar input and to charge almost 4kwh isn't going to happen on the best day in the winter where I live. That is a huge cautionary tale for anyone looking at this for off grid.Edit #2: So I am halfway through winter and found two things out. I can extend the standby by turning off the power to the outlets and just keeping power to the USB chargers. This gives me roughly 10 days in standby mode and I can still log onto the unit and see what the power is and it still connects to wifi. Only problem is it does not charge below 40 degrees Fahrenheit. So for the most part it will be sunny and will not charge if it is under a certain temperature.

Had a large gas-guzzling Honda 7000/12000-watt generator that didn't have an electric start and was too loud to run in my current housing development. Not to mention it was a bear to set up and startup. Chronic back pain prohibits and limits my ability to set up and run this outdated and inefficient solution. So, I did some homework and found the ECOflow product line. I already owned the ECOFlow delta and using it as a temporary solution to keep my fridge, microwave and a few lights going during a power outage. Then ECOflow introduced the Delta Max and Delta Pro. I decided to purchase the Delta Max and 2ea additional smart batteries. My reason for this was product weight, product foot print and cost. The Delta Max solution was easy for me to move/transport and setup. At around 50 lbs or less for each module, I can easily move and setup this solar powered generator solution without wrenching my back. I now have a quiet, efficient Backup power during those unexpected power outages. With just the Delta Max I had around 4 hours of battery backup run-time. I am talking about powering every thing in my home except those devices that require 2-phase power. With 2 additional smart batteries I now expanded my capacity to 6kWh and have roughly 12 hours of runtime. I purchased 4ea Ecoflow 110 watt solar panels and plan to build a portable frame to put them in my front yard to charge up the batteries using solar power. In addition, I purchased a Generac 7117 Gp2200I W 50St Inverter generator that weights around 47 Lbs. It’s light and easy to move around. It’s very quiet and extremely gas efficient. I use it to charge up the solar generator batteries when there is not enough sun light. I live in the PNW so it’s not the sunniest place in the USA especially during the winter months. The Delta Max has a smartphone application that connects via bluetooth that I use to determine my power consumption, run-time remaining and many other aspects for controlling the solar generator environment, including doing firmware updates as required. One neat feature of the application is that I can control how much power the solar generators demands of the gas generator while recharging the batteries. The solar generator can demand as much as 1800 watts of power during a charge cycle. I like to limit this to 1300 watts. This lowers gas consumption and noise on the gas generator during a charge cycle. The Delta Max has the ability to provide 3400W of power with ease using X-Boost technology. This allows the concurrent use of power hungry device like microwave, fridge, heater, dish washer. ect… You can use the application to stay at or below the 3400W limitations. For me it was easly achieved. I even keep my bidets powered during power outages. I just put them in low power consumption mode. Do your homework and be smart. Determine your wattage requirements for all of the items you want to power up during a power outage and then determine the worst case aggregate power requirements and you’ll be able to determine what devices can run concurrently using the Delta Max during a prolonged power outage.Use this link to purchase a cable to connect the Delta max to your existing Generator power transfer switch:https://www.amazon.com/gp/product/B08H85RQ6X/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1I really like and am impressed with the products that ECOflow manufacture. I am very tech savvy and a DYI guy so it wasn’t hard for me to research and integrate this product for a reliable and safe electrical backup solution. I haven’t had any issues using this solution during several outages since installing it. I haven’t had the need to call their tech support so I can’t comment on there abilities to support the product. I did my homework thought and it seems that they have their stuff together for good customer service and support.
