Off grid: Ecoflow Delta Pro Losing charge overnight when the inverter is on
HTML-код
- Опубликовано: 24 июн 2022
- The Delta Pro uses about 45 watts when the inverter is on even when there is no power draw occurring. This video shows how much battery is lost from when the solar panels stop producing power in the evening, to when they start producing power in the morning (spoiler - it's 16% battery). This is good to know if you want to save as much battery power as possible and are not using the inverter for periods of time. Turn the inverter off when you don't need AC power to save your battery power!
Thanks for this as it's just what I was looking for.
Another channel tested the inverter loss for the Delta Pro Ultra and found a 7% loss in 12 hours at idle which corresponds to your experience. It's good to hear that there's little to no loss with the inverter off as I plan to use this as whole home backup with no solar. The Anker F3800 lost 23% of its capacity at idle just powering the inverter for 12 hours probably due to its low frequency inverter as opposed to a high frequency type in the DPU. These are factors that should be considered before installing any of the battery units for backup as that's significant energy draw that has to be replenished.
This is quoted from Delta Pro's User Manual regarding AC Output Port, "The default standby time of the AC Output port is 12 hours. Without any load access for 12 hours, the AC Power will automatically turn off. Please turn off AC power button when not in use to save power consumption." As a matter of fact, in the EcoFlow App, in the settings, you can change the "AC Timeout" to the lowest setting "2 Hours". That will save more power and give you peace of mind, even if you forget to turn the AC switch off.
True, thank you.
All power stations have that issue because the inverter draws something like 2 to 4 watts just being on and nothing plugged in. Some are much more efficient than others. Not sure what the Eco flow pros rating is for idle consumption. I want to say most Eco flows get around 85 to 90 percent of the power available on the ac side due to the inverter consumption in the tests i have seen people do on RUclips, like hobotech who tests from full to 0. Also remember just having wires plugged in can draw small amounts of power, so you could be losing a couple of watts just on that. that is why they say to unplug your devices to save electricity. You can test that by leaving it on and see how much it drains with nothing plugged in. you lost 16 percent in almost 12 hours with things plugged in, so if you lose less with nothing plugged in and the inverter on then that is the parasitic draw from things just being plugged in. Still 16 percent in 12 hours in not bad especially since you're charging with solar.
Mine loses 20% charge overnight every night, and the inverter is off. I've never seen a backup battery that lost so much charge so consistently. It's definitely not a good design if so.
This is the first time I have seen an issue with the inverter of the Delta Pro. I have been using mine for about 3 months now and no issue whatsoever.
This is not an issue. Anybody, who has ever dealt with any inverter, esp. RV-er, knows inverter consumes energy when it is on. The simplest thing is when you don't need AC, turn off the AC inverter. As a matter of fact, in the EcoFlow App, in the settings, you can change the "AC Timeout" to the lowest setting "2 Hours". That will save more power and give you peace of mind, even if you forget to turn the AC switch off.
Thanks for sharing this.
Power off the unit, when not in use. It does very well holding a charge for a few weeks without any power lose.
You should email or contact Ecoflow's customer support. I am sure they will look at this asap.
Good to know! I have the extra battery and I don't know why the whole thing doesn't use up the extra battery first. Like if you set the main unit to discharge till 30% charge left over - I wish it would just use the power of the extra battery.
Latest version of the app has lab features that allows you to define the periode you want AC-out to be on. That can help you limit the losses on the inverter. I hope it works on your Delta Pro
My Delta 2 max does the same thing but only about 10%. Hopefully EcoFlow will address it with an update. I’m running a Powerstream with a max and max spare battery (4kw), the app could do with the ability to remotely put the system to sleep onto an ultra low power mode. Still loving the system though 👍🏻
This is common to all inverters, although the EcoFlow inverters seem to be a bit less efficient. Not a bad thing to learn if you are new to all of this.
I'm thinking because it's such a large inverter, 3600w, that it draws more than smaller ones...?
They should have a auto turn on features like turn off at 10pm and turn on when it sense solar input or 7am something like that
I have the delta max 2000 and all is the same for the delta pro. If you set your ac timeout to maybe 2 hours or as needed. Then 2 hours after your last load was turned off then the inverter is turned off. You could also do unit timeout that would shut off completely. And then in the am when the sun comes out the unit does come on for the mppt Controller to start charging the battery. if you would like your inverter to come back on then in his situation you could put your charge cord on a wyze wifi plug like i got and set the times on and off and set the delta app to to turn the inverter on after power restore. Then once you have the wifi plug set to come on all it needs is a few minutes to activate charging to turn on the inverter then it can be shut off moments later. Kinda like when I had my plug set from 6am to 8am for my block heater on my truck. That was energy wasn't waisted and it was reset everyday on it's own.
I think you should check the settings in the App. That's what I did when my Delta Pro was not charging completely. It was my bad.
My first one discharged 8% per day plugged in to AC and running a 100 watt freezer. That is bypass mode where AC output is from the wall socket. No battery backup system should discharge in that mode. Even trivial monitoring functions should not discharge it that fast. I was told to discharge and recharge 3 times to "calibrate" the battery and to update the firmware. So I did. Did not fix it. So I returned it. The new one discharges 2% per day, same setup as before. What use is a backup if it is dead by the time a power failure occurs? When you are a thousand miles away? Why does it not use wall power for monitoring, Bluetooth, Wifi? Or automatically recharge when discharge to 95% or so? This is an outstanding unit but best for camping, RV etc. Unbelievable the amount if digging, research, experimenting to do that should all be in their advertising and manual, it is not.
I had the same issue with both my delta pro's, overnight they would drop from 80 or 90% to25%. I finally figured out that if you have the solar and 120v input unplugged, with the delta pro on, push and hold the power button for 30 seconds. The delta pro will shut down and reset/ recalibrate. after that the delta pro's would hardly drop at all.
I just did this and mine went from 68% to 93 %. Now i am confused. Well i will let it run to 5-10% and see if it just recalibrated.
@@johnr6676 charges it to 100% first, then unplug everything and preform the reset
It's true the larger the inverter, and the larger the load you put on it, the more more watts it uses. You can use the timeout settings to shut off your AC when not in use.
The Delta Pro does have a 30 amp 12 V output, enough overhead to comfortably run 12 V systems in your RV. Smaller units that only have 10 amp 12 V outputs will have trouble trying to run a 12 V refrigerator, a couple of fantastic fans, and LED lighting, etc. all at the same time. So that's one thing to look for in these type of devices, that the Delta pro can provide.
The second generation Deltas do use less power just running the AC inverters though, my Delta 2 in idle with no load only uses about 15 W an hour. That's half what the original Delta 1300 used. So when the delta 2 Pro comes out, it is going be much more efficient for people that need to run AC power all the time.
Good info. Thanks for the comment! 👍
I was thinking the same thing, need to find a generator for my refrigerator. If it drain while AC inverter is on, then would need bigger battery to keep it running all the time.
3600w 88% efficiency - 3,168w
83.70% After 16.3% night drain (516.4w lost) 2,651.62w available
You should have 10 days with the battery at 100 % not 5 I exchanged mine for that reason now I get 10 days at 100%
there is a little power lost with the wifi too with the inverter off.
if it was plugged into your shop, couldn't there be devices plugged in that are power bricks that have to oscillate the transformers inside? Each of these would have a resistive load, even though the transformer isn't consuming power out the other side. You could try leaving inverter on, but unplug the shop from the ecoflow and see if you see the same drop the next morning.
Yes, I did that. The power loss stopped, you are correct.
Try unplugging the Delta Pro and update the firmware. It may help.
Funny you should say that, I just updated it yesterday, I'll test it again soon.
I use mine in my 18 wheeler and it does the same thing.
Thanks for the confirmation.
You can set an AC time out in the app. May be a few hours would work?
True, there is a setting that shuts the inverter off after a certain amount of idle time. I don't have a problem with losing that much charge overnight because the solar panels charge the unit to 100% before I start using any power in my shop. Plus, I can use the app to shut the inverter off if I need to save battery power.
I have two delta pros I usually leave them both on but haven’t seen a drop like that overnight with them on that’s weird I will test one tonight
@@sikc6z415 Please do ☺
@@bladeslicemaster5390 been 13 hrs left ac and dc on dropped from 99 to 92%
@@sikc6z415 Thanks. I'll try unplugging everything and test again. I have a clock, smart-switch, wifi-repeater, and power strip that runs all night.
