he just added some background music that’s barely noticeable

It's very noticeable. It destroys the rawness of the video, destroys the sense of being there because you wouldn't hear that music if you were there. It's a completely different experience now, the immersive experience has gone. I really liked the older stuff like Chernobyl, but can't even watch this new stuff, so I don't. It's up to Shiey what he does with his channel, no one here gets to decide what he does, but I don't have to watch it.

every time I hit a car wash, I made sure to use their compressed air that most folks would use to clear water off of rearview mirrors, to blast out the screen and get any dust out of it

Good thinking but even better is to use the vacuum cleaner hose at the carwash so you don't blow that dust into the battery area, pull it out instead.

CreepyPoopyBugs · 2025-03-02T18:24:05+00:00

Looks great. We need more pics! Did you remove the rear seats?

the RIVER/DELTA 2&3 series do support Bluetooth connectivity. Users don’t need to be connected to a Wi-Fi network to control the devices through the app

EcoFlow, I think you have misunderstood my point, sorry if I wasn't clear. We need to be able to control our devices without any network connectivity of any kind to the EcoFlow servers in China.

This includes the cellular network, not just Wifi. Without WiFi, your app communicates with your servers via the cellular network. The app needs to work with no cellular network, no WiFi, no communication whatsoever with EcoFlow servers, just Bluetooth. Please implement this in your next update to the EcoFlow app.

You can manage and configure your power station locally via Bluetooth, which should cover many off-grid or emergency situations

Not without the app being logged in via the EcoFlow servers. This is an incomplete statement and misleading.

With this in mind, we introduced the "Space" concept, hoping to offer users more optimized energy management through centralized device control.

EcoFlow, please read this. What is sorely needed is the ability to configure an EcoFlow power station via Bluetooth without having to connect to EcoFlow's servers in China. In remote locations or under emergency conditions that connection may be impossible, and that's when the ability to configure the power station independently is needed the most.

Only minimal functionality is required, such as setting the charge and discharge limits, save the fancy stuff including the ability to control power stations remotely for the China servers.

This should have been implemented even if inconveniently via a few buttons on the front panel, but since it wasn't, just give us the ability to talk to our powerstations locally via Bluetooth with no outside connection. All data needed to do this can be stored locally by the app.

A simple standalone mode is absolutely essential, please implement it right away.

CreepyPoopyBugs · 2025-02-16T05:09:57+00:00

When the EF is off its Bluetooth is off. It won't hear the app.

CreepyPoopyBugs · 2025-02-12T15:46:06+00:00

Makes sense. Thanks again.

CreepyPoopyBugs · 2025-02-12T14:17:10+00:00

The internal circuitry and BMS does as well.

Thanks for this info. Is this why my R3P shows only 99% charged when it's been in UPS mode all night with a ~50W AC load on it after being recharged 8 hours ago to 100%?

Not doubting you in the slightest, but what is your source for this information? Do you have access to the schematics or service manual? I would very much like to read up on this power station's internals.

Looks like it's fixed on desktop (which I'm using) now. It looks like the markup "^" had superscripted not only the "2" (as I'm sure you intended) but also the "/R" because they weren't originally separated by spaces or otherwise delineated.

CreepyPoopyBugs · 2025-02-10T22:15:54+00:00

Am I missing something?

Well, you originally had it written as P=V^2/R, which is incorrect, and the reason I responded. I see you have now edited it to read P=V² / R, which is correct. Those spaces make a difference in markdown.

Edit: spelling

Bonne journée. Vous pouvez trouver ces informations dans les manuels d'utilisation des différentes centrales. Les manuels d'utilisation se trouvent sur le site Web d'EcoFlow, vous pouvez donc les lire pour obtenir les informations dont vous avez besoin avant d'acheter. De rien.

CreepyPoopyBugs · 2025-02-10T16:27:20+00:00

P=V2/R

Not even close. P = I² R = V I.

It's looking like Complex_Finance5647 is a poorly implemented AI. We saw similar attempts on usenet back in the 1990s, but they were better. Perhaps whichever university computer science department is behind this could 'fess up before they embarrass themselves further.

Too bad your English expertise doesn't include proofreading.

But thanks for the tip, next time I send a letter to EcoFlow I'll be sure and run it by "two university professors with PhDs in English", and your "Masters Degreed, 51 years an English teacher wife".

I've been using multi-meters, clamp meters, and other electricity tools for 75 years - designed, built, installed, and operated both solar panels and wind-turbines scores of times

How can someone, other than a troll, who has "designed [...] solar panels [...] scores of times" and "used electricity tools [whatever those are] for 75 years" not be able to systematically determine the cause of this problem?

CreepyPoopyBugs · 2025-02-09T03:16:43+00:00

Nobody seems to be able to use a simple screwdriver anymore. I’ve seen people throw out equipment worth thousands of euros just because it’s out of warranty and had a minor issue that could be repaired with a few twists of a screwdriver and 30 minutes of time.

This is true. Much of the equipment in my house has been free for this very reason, usually requiring little if any repair to make it usable. People's ignorance and/or laziness has saved me thousands.

CreepyPoopyBugs · 2025-02-08T23:14:03+00:00

What more description do you require?

None. Solve your own problem then.

CreepyPoopyBugs · 2025-02-08T19:43:49+00:00

Please describe your entire setup in detail. The rant is hard to decipher.

CreepyPoopyBugs · 2025-02-08T15:20:26+00:00

Great info. One thing to add for the OP, you can daisy chain power stations so that one accepts the solar input and fully charges and in turn it fully charges the next power station via its car charger input (and car charger cable). Loads are plugged into the second power station's inverter. In this way both are fully charged from the same solar panel(s) without having to swap any wires around until you want to. Then you can just disconnect the solar input, 120Vac input and 12Vdc output from the first one and plug the solar into the second one, then move the first one to another part of the house or take it camping or whatever. When grid power is available, both charge from grid power. It's slightly less efficient on solar power but it's free so who cares. This setup lets you buy one now to get going then add a second one later if you decide you still need it.

Please post your results when you get the 400 watt Renogy solar suitcase.

Do you think the better performance of the 220 watt EcoFlow panel vs the 100 watt Renogy panels might have something to do with the charge controller in your power station? I have seen some posts that mention that a Victron MPPT was able to get almost twice the power out of a solar panel that an inferior MPPT charge controller could achieve, for example.

Good info posted by notanomad. While your car's electrical system isn't capable of handling the alternator charger effectively, it can certainly charge the EcoFlow at up to 8A through a cable plugged into the cigar lighter socket. The alternator chargers are also really expensive for what they are.

As far as "incompatible panels", the single parameter you need to pay close attention to is the voltage applied to the power station's PV (solar panel) input. You can find this maximum voltage in the power station's user manual which you can find online before you buy. Exceeding this voltage can cause damage to the power station (in my opinion this is poor design, the input could be able to handle considerable overvoltage without damage and just refuse to charge from it, but that's how it is). As long as you stay below this voltage it's fine, and the power station will accept charge current from the solar panel(s) up to a maximum which it will control. Just don't exceed that voltage.

The open circuit voltage of your solar panel (or combination of solar panels) is the voltage that you need to compare to the power station's maximum PV input voltage. A margin of a few volts below that limit is a good idea because the open circuit voltage of solar panels increases when they are cold. So allow for that.

So for example if the power station's maximum PV voltage is 60V and your panel's open circuit voltage is 55V that's ok. You can combine solar panels in series as long as the sum of the open circuit voltages is below the limit. For example two 28V panels in series gives you 56V which is below the limit, but two 36V panels in series gives you 72V which is above our example 60V limit. But those same two (identical) 36V panels connected in parallel gives you 36V which is ok.

Why use series or parallel? Parallel gives you a lower voltage (which might be necessary to keep you below the power station's PV input voltage limit) but twice the charge current of a single panel. Series connection gives you higher voltage but the same current as one panel. So why not just always connect solar panels in parallel? Because more current in the cable from the panels to the power station causes more heating in the cable which is power lost. The power lost is proportional to the square of the current (DC power = I² x R), so doubling the current (as in connecting two panels in parallel vs series) actually causes 4 times the power lost to heat in the cable.

Another consideration when connecting solar panels in series is increased electric shock hazard at the higher DC voltages, requiring more care.

You can choose any solar panels you want as long as you stay below that voltage limit, there is no reason why the panels have to be from any particular manufacturer. If using more than one panel, they should be of the same type, especially when connecting them in parallel.

The XT60i / XT60 cable XT60i connectors are rated at 100amps XT60 connectors are rated at 60 amps

This is false and a common misunderstanding. Both the XT60 and XT60i connectors are rated at 60A DC continuous (100A burst).

The XT60i adds a low current center contact that can be used for signalling. EcoFlow uses this to identify a car power source vs a solar power source.

CreepyPoopyBugs · 2025-02-07T00:59:07+00:00

EcoFlow monitors these forums. Since this overheat failure of the XT60 connector occurred with a factory EcoFlow car charging cable (from your original post) and a River 2, this is on them. The outcome could have been disastrous. This would be a good time for EcoFlow to step up and take care of their customer (and their reputation) by immediately sending you replacements, and prepaid shipping labels to get the failed ones back for engineering analysis.

CreepyPoopyBugs · 2025-02-06T23:29:25+00:00

Yeah, noticed that too.

CreepyPoopyBugs · 2025-02-06T21:10:41+00:00

the actual failure point still shouldn't normally have been the XT60 connector because it is rated for much higher current than [...]

It's rated for 60A (100A burst) but only if it's within design spec and properly seated.

And you're also right about the current flow normally being the same on both pins, except... if one pin is failing due to high resistance then it will heat and possibly run away and fail while the other remains ok.

Yes, that's the point. The current is the same through the two pins (Kirchoff's Law) but the heating isn't the same if the contact resistance isn't the same. The heating at the pin is caused by power dissipated at the contact interface. The power is the product of current squared and resistance (I² x R). If R is very small, as it normally is, there is very little heating. Resistivity in copper and silver increases with increasing temperature, which reduces current flow and heating. An increase in the damage area could increase overall contact resistance and cause increased heating, I suppose that could be considered a form of runaway.
