EcoFlow Delta Pro Whole Home Backup - Real World Testing

This test would indicate that with just AC power at idle the consumption is only 18 watts and that is quite good. An interesting feature of the Delta Pro is its variable speed AC charging. It has a switch on the back to switch between slow and fast charging. Slow loading. It's better for the batteries, but if you're in a hurry you can charge them quickly. Trickle charging from zero to one hundred percent took 10 hours and 39 minutes and consumed 4.62 kilowatt hours, representing an overall round-trip efficiency of 65.4 percent in fast mode. charging mode, it only took two hours and seven minutes.

Well, I have been running them for several hours and now it has been powering many circuits in the house, well, lights, microwave and kitchen appliances. I won't try to add a little bit. from a few solar panels placed in the backyard, it's not very sunny today but the first thing to do is check and make sure the voltage is within the range of the unit and we are at 107 volts so definitely within the range. and we can plug it into the rear port, mount my clamp meter. I can measure, they don't go in, so I have three amps, almost exactly three amps, well below the capacity of the unit and those panels, but there's not much sun to work with today.

So yeah, we'll take what we can get. Now you can see that we have about 270 watts input and 360 more watts output, almost balanced input and output for this particular inverter. We had a few more panels. I could add them to the other one. inverter, so we'll let it run like that for a while. I want to see how the imbalance between investors works. Can they handle it between themselves or are they becoming more and more unbalanced? Well, this is definitely the most pluggable method. and Play System that I have done so far, I set up the two units together, connected them together, added my extension cable to go to the transfer switch input and flipped the transfer switch, we were up and running and then to add a little . of solar power, I hooked up some panels in the yard and put a cable on the back of one of the inverters and voila, we have solar power going in and out 120 and 240 volt units working without problems, so far, it seems that The imbalance in the discharge and charge is not automatically balanced on this side, we have incoming solar and it keeps it at almost 100 percent and this non-solar unit has the majority of the load so it dropped to 75 percent.

I

real

ly hope the units automatically balance the battery charge between them, but it looks like I'm going to have to manually move the solar input to the other unit to try to turn it up because this one is fully charged. It's okay, it's been very cold. so I thought I'd do a cold bath, it was about eight degrees Fahrenheit. I let it soak overnight and we'll see if it can get things going and whether or not it will charge under those conditions. I have the remote screen. here, see if it turns on fine, the inverter turned on, let's see if it works fine with a 600 watt load, wow, that's pretty good.

I'm surprised it's running at this low temperature, turn it on, yes almost 1200 watts so it's working. No problem, plus when I turned off the battery last night it was at 75 and it still shows exactly 75 percent. Alright, one of the other issues with using these batteries in very cold weather is charging, so we've seen that it can actually provide power. Let's see if we can charge it at this temperature. I heard a click and it's not charging and you see there's this little low temperature icon flashing on the screen here and that's exactly what it should be doing because these batteries don't like to be charged underneath. is freezing, which tells us that the low temperature sensor is working and that the unit is protecting itself by not charging at these temperatures, so what that tells you is that you will be able to use the power of your unit when it is very cold, but you won.

You will not be able to charge it until it reaches the current temperature. If you're using them in an off-grid situation where you're continually charging and discharging them every day, you'll need to make sure you keep them. In a place where they are above freezing, the largest 240 volt load I have in the house is this geothermal heat pump. It's a three-ton heat pump, but it's not connected to my emergency circuits. I never thought I would be running such a large load. shutdown of an emergency capable device, but today we are going to try to see if the

ecoflow

system can power my entire heating and cooling system.

Don't do this at

home

, but I have connected the system directly to the geothermal heat pump using an extension cord. cable so I have both Eco streams connected with a dual voltage hub and then connected the geothermal unit directly to it so I can supply 240 volts. I'll use the Fluke meter to measure the input current and then switch to current and then use my key watt meter to measure the voltage. Okay, I'm going to turn it on, let's see what happens, a pump, oh, overload, well I know the running load it could handle, so it looks like what an overcurrent it is. very high and I can measure it very quickly using the AC connection only as a reference, but apparently that's too much for the system to handle.

I know you'll handle it once you've started, maybe there's a soft start system that would allow you but it seems like the geothermal heat pump is too much, okay. I switched it back to mains power. Now I will turn on the unit and see what the actual input current is. I wrapped the current sensor around the line that goes to the heat pump motor only, so we don't catch the circulation pump turning on the input current too soon and I'll try again. Foreign 203 amps, no wonder it failed. 203 amps is a lot, no wonder I couldn't select.

That's fine, well, I guess it's un

real

istic to think I could ever take that bomb overseas. Let's put this all together with some conclusions first. This is a truly Plug and Play

backup

system. No experience required. First connect the multi-voltage concentrator to the Delta   Pros then connect the Hub to the input of your generator, then you simply have to turn on the multi-voltage Hub and activate the transfer switch and voila, you can run everything in my house, all 240 loads volts and 120 volts, except for my three ton geothermal heat pump, which was not unexpected. My heat pump has a huge cranking current of over 200 amps and that was too much for the system, plus it can run the 240 volt microwave lights and other appliances all at the same time.

At the same time, there is no need to run extension cords everywhere in case of emergency, just use all your appliances as usual. It has multi-speed AC charging and a very capable solar input. I didn't have a chance to fully test the solar performance, but the 1600 watt input has great specs with a voltage range of 11 to 150 volts and a maximum current of 15 amps, which is a great range and gives you plenty of options for setups. of solar panels. For some reason, this mc4 to xt60 connector does not come with the unit, so if you want to do any solar charging, be sure to order this accessory.

The system has temperature sensors to protect the battery from charging in sub-zero temperatures. Something to keep in mind if you are operating in a sub-zero environment. You can discharge it, but I won't be able to charge the battery. One of my favorite features of this power station is the ability to manually set the maximum charge and minimum discharge status of the battery whether you are using it as a UPS or for a short shutdown. Grid system This allows you to adjust the upper and lower limits and greatly increase battery life. The UPS function works very well providing true AC power with no impact on the battery.

The physical position of the dual voltage hub is a bit awkward and when you plug in a dual voltage hub the 120 volt outlets on each unit are disabled if you are running everything from

home

, that's fine but it would be nice if

ecoflow

will include at least one pair of 120 volt outlets on dual voltage. Hub, but in the spirit of Plug and Play I have a solution. You can purchase this 240 volt splitter to double 120 volts on Amazon and voila, you have access to 120 volts. Now I can connect the iron to a foreign power outlet on the first inverter. 1300 Watts I can connect this heater to the other one.

Now the other inverter is delivering a little over a thousand Watts, so go back to 120 volts of power to each inverter through the 240 volt hub. If you need, you can get a splitter for the output of the Hub so you can run both the house and the splitter at the same time, so there is an easy Plug and Play way to get 120 and 240 from the Dual Voltage Hub. , maybe in the future they will update it so you can do it right away. from the Hub itself, but for now there is a plug and play solution. Unfortunately, the units cannot share battery capacity.

If you draw more power from one leg of the system, you won't be able to get the most out of the total combined battery. Capacity I heard from the Ecoflow technicians and the reason for the slight imbalance and voltage between the legs is an intentional method to help balance the state of charge between the units, which is pretty clever but not enough to resolve large imbalances, it seems . ecoflow could solve this problem by connecting the two Delta Pros with the same cable used for the expansion batteries through these additional ports and then some software to help balance the load.

It's not a game changer, just something to keep in mind when planning your capacity. and circuit distribution in its subpanels. I hope this has given you a good first look at the split phase capability of the ecoflow Delta Pro that can be achieved with just these four parts. Overall, this is an amazing system. The combination of functions. The simplicity of use makes it a great choice for a home emergency
