Another Victron to Ecoflow thread

[Lazyass]

Also, with the non-smart unit, I don’t have it the protection from running out my starter battery when the engine isn’t running.

You can use D+ signal for turning Orion ON so it will only supply power when engine is ON

I am about to do the same with Orion TR(non-smart)-12/24 15A in combination with XT60i (middle pin to negative (-) ) to Ecoflow Delta MAX 2000 (13A max for solar here in Europe, for USA specs says max 10A ! but I think is mistake ) for maximum wattage when engine is running !

My question is: does MPPT of Ecoflow "takes" what it needs from 15A available or it "takes" averything available ?

I will put it to 30V just like this page says it is possible for Delta MAX ... : Orion to Delta

This is tough to say.
When charging the ecoflow delta 2 via the victron 12/24 15amp non-smart converter I get a constant 405watts into the Ecoflow (as measured by the ecoflow)

I can’t say if it’s the Ecoflow that is limiting the flow or if it’s the Victron.

Or am I misunderstanding your question?

Yes it is strange question, not really answered around the internet: Victron gives 15A max and V let say is set to 30V ...

The biggest questions is: will Ecoflow limit that A to what it can take on itself (Delta 1 MAX has 11-100V 13A Max, 800W max limit, while Delta 2 has 11-60V, 15A Max, 500W max) or will take all and stop charging in case of Delta with 13A limit .....

Since you Delta 2 is 15A there I don't see problem but it is different with 1 MAX !


This question is here because if you look at solar panels is there only Voltage of panel setup to be care off or is both V and A ? (if you offer to much available A to Ecoflow, what will Ecoflow do with them

Ah. I get your question now.
But sorry, I can’t answer it since I don’t have one of the ecoflow extra batteries.

Perhaps on one of the ecoflow forums?

I just found that info finally ... You need to keep Voltage in range, Ecoflow will not take more than it needs so even if you put Orion-Tr with 20A it will take it's max (10/13/15A) the same is with panels .... group of them you need to keep them in V limit A can be whatever ! It is better to go over with A than lower because in case of lower you push converter to the limit all the time

Just come cross this thread. This is exactly the issue I got since I got the smart 12/24 - 15A installed last Sep. I got same setup as you with Delta 2 and extend battery.
I saw 380w input the first day I finished installation then 280w later on no matter how I configure victron in its app.
I don't have REDARC to help preventing drawing power after turning off the engine. So I guess I will live with it for now. Probably consider the 800w ecoflow charger when price dropped.

You could run that extra wire to the remote start on the victron so it turns on and off with the engine.
That way you wouldn’t need the redarc.

Though, for what it’s worth, I don’t trust the Redarc. I unplug the deltaflow at nights.

Bumping this thread with a couple of random thoughts. For those using the Victron Smart Tr units I *think* the issue is that the MPPT controller is trying to vary the voltage. The Smart Tr sees that and adjusts, thus drops the voltage. Those using the "dumb" version do not have this issue.

Regarding running a wire to remote start on the Victron what would one be tapping into? That is the simple option would be to something like a aux port (cigarette lighter) that comes on. But that is on when the vehicle AUX is on whereas one really want something when the engine is on. One can use a Victron Battery Protect so that the converter only runs when the supplied voltage is above 13 V.

You mean the dumb versions “don’t have this issue” right?

But if you haven’t already purchased the victron, why not just get the Ecoflow fast charger for cars?
I think it has protection to protect your starter battery. And I presume it plays well with our ecoflow batteries.

And they have dropped prices from that initially stupid $699 they were asking.

Correct, typo. Sorry for the confusion (fixed my original post).

Correct again, both EcoFlow and Bluetti now have their own system as does GoalZero. All have battery protection. And yeah the initial prices were stupid. One can find them for $250 - $400 separately or even less with a package (There are some good sales right now).

However, there are other systems out there that do not.

I have the 800W Ecoflow Smart Alternator and 2 Delta 2 in my 100 series. If I'm idling or driving stop and go, I usually have it set at 20-30A and don't see any voltage dips (I have an 180A upgraded alternator from DC Power can handle that). Once I'm on freeway I will bump it all the way up to 55A (with my voltage booster ~15.1V, I hit 800W charging to the Delta 2). If I had the 270 or 370A alternator, I think I could leave it at 70A without out issue.

I like having the ability to reverse charge my starter battery, but it's not automated where it will switch to maintain the starter battery once it's at say 100% charge. Ecoflow offer two modes: battery maintenance (max 100 W) and reverse charge, which I think let's you send up to 70A? But I have to double check. One other thing, is can't customize the charge voltage to the starter battery (it is hard set at 13.7V or 13.8V). I have the second Delta 2 trickle charging with the DC input.

On the Ecoflow Smart Alternator Charger, you can select the max charge current from 10A up to 70A on the 800W model in the app. One negative about Ecoflow, is that it requires wifi connection to update the firmware to the alternator charger and power stations, which can be a pain. You also have to update the first time you install it. App has worked well once in the field, dont' need wifi to use it. It connects with bluetooth.

One thing I noticed at least with the Ecoflow Power Stations, is that below 32 degrees F, they will not charge until the power station temperature is above freezing. We were camping in Yellowstone NP over the holidays and it got to -10-12 F and in the AM, I was surprised that the station would not charge. After some reading, I found out the BMS (battery management system) on the Ecoflow was prevent charging to protect the cells. Once the trucked warmed up to about 40 F it started charging again.
