Agreed… mostly. But with an Ecoflow, the lower voltage means that the mppt on the ecloflow limits the input wattage. If I’m getting 28V I get 370watts (roughly) in and if I’m at 20V, I get 280watts into the Ecoflow. This means charging time is 30% longer. But it’s still much much faster than...

Argh! Even in power mode the victron still only puts out around 20V - even when I have the output set to 28V. At this point, I have to assume it’s either something to do with the MPPT in the Ecoflow. Or my Victron Orion is faulty. I would bet on the former since I can, at the beginning of a...

Perhaps I shouldn’t say “creep up.” What I mean is if there is a load and you use a multimeter to check voltage it will always read lower than when there isn’t a load. So when the Orion stops charging due to the voltage dropping to X, the voltage will bounce back up to something higher than X...

Oh…. But tell me if I’m thinking about this wrong. The way my battery creeps up in charge is by taking the load off of the circuit. It always reads a higher voltage when it’s not actively charging the ecoflow. So when the voltage drops to whatever my shut-off V is, the Orion stops sending power...

Ha! And I’m not sure how the Redarc BCDC is also affecting the entire equation. But I’m in the process now of shortening all my wires and then I’ll try again in just power mode. Also, keep in mind that it’s the Aux battery, not my starter battery. Which further emphasizes what you are...

Yes. That’s certainly the case. Lots of opinions out there. I suspect part is due to how few people actually understand electricity (I am not one of those select few) and then Ecoflow further complicates it by trying to obscure things so you have to buy items from them - which I would be good...

Though I did just find this: http://www.linspyre.com/ecoholics/alternatorcharger.html Seems like Ecoflow has seen the need for faster charging from an alternator and is coming out with their own device that can handle 800W. That will be nice if it/ once it gets released. Perhaps it will...

Yeah. Agreed. I think that 1100W DC is an error. I believe it can charge the ecoflow at 1100W AC. But DC is limited to 15A/500W. And yeah, I think the MPPT is the culprit. I’ll try different settings to see if I can fool it further.

Yes. I did buy a new one. Also, Im not sure anymore, but I don’t think an XT60i comes with the ecoflow. But I first purchased the solar power connection that Tinkerer recommended - I was going to modify it like he did but then saw the connector on Amazon that I linked above. It’s a big bigger...

Correct. I’m using the PV input. It’s the same input as the car DC. The wire that the ecoflow came with to charge from a car is XT60. The input from solar uses the same port, but that wire is XT60i. So I’m using XT60i from the alternator to fool the Ecoflow into thinking it’s getting PV input...

Agreed. I tested this yesterday. Increasing the RMP only increased the voltage at the main battery by 0.1 to 0.2V. At the Orion back in my cargo area, higher RPM’s had no effect on the voltage. This may be due to the cargo area being on the back side of my REDARC BCDC.

“PV input?” What input is that? I’m using the input that is for either the car DC or the solar panels. Using this wire: https://www.amazon.com/gp/aw/d/B0CNJQZ65W?psc=1&ref=ppx_pop_mob_b_asin_title Basically if one used XT60i, the ecoflow thinks one is using solar panels and allows for higher...

@FrazzledHunter, I cut and pasted your response to this thread. I hope that's okay. I realized I was hijacking that other thread (again). But I'll take those measurements like you suggest. Are you taking those measurements at the battery or back at the Vicrton Orion 12/24 -15? And I take it...

Right now the wires from the busbar to the orion are 4ft. (1ft of 4awg and 3ft of 6awg) And then the wires from the Orion to the ecoflow are another 4ft or so. I will be cutting them shorter in my final set-up but I wanted to leave some length to play with while I am testing it. You think...

Sure glad to. The quick answer (scenario 1 below) is this: Input voltage lock-out:12.5V Voltage to resume: 13.2V TL;DR However I have 2 scenarios: With the Victron connected to the starter battery what I am trying to do is have the Victron turn off immediately after engine shutoff and resume...
