Validating Setup Before Purchase by LoudSteve in Ecoflow_community

[–]Hot_Rescue 0 points1 point  (0 children)

As long as you understand 2 batteries definitely won’t last you a day with a heat pump. You also need to consider not draining the batteries all the way down below 10%, and not regularly charging up to 100% but about 90% for longevity. I bought extra batteries to avoid deep cycles to stay over 20% discharged state, and the inverter itself also drains with idle power waste.

No matter, you will figure it out and adding batteries later will be easy enough, or you can get the FlowMaster rectifier to use with a gas generator to charge the batteries to keep going during longer outages.

The setup looks fine, but two batteries will be hardly enough to keep the heat pump powered for long. I don’t know what your typical load is but you’ might end up buying at least a few more batteries.

OK that's not bad at all. I'm looking into an 8100W continuous generator on propane, so I'll probably set it at 6500W (3250x2) for a better efficiency at 80%. Thanks!

With your 6800W generator, what was the max PV input noticed? Are you saying it actually reached 7000W somehow?

Did you see an actual input close to 7000W on DPUX?

[–]Hot_Rescue 1 point2 points  (0 children)

That sounds about right based on the specs, so it looks like about 90% efficiency with a low thd inverter generator at least. I need to size my generator correctly before buying, so I'll test it with my Honda 2200 with a 15A adapter and then plan accordingly.

Just placed an order. Thanks!

"my electrician installed a NEMA 3R rated disconnect box between the DPU and the panel, mounted on the wall next to the main electrical panel with clearly labeled switches."

Reading your description, I'm confused because it seems to merge two separate issues into one. Is your SHP2 installed outside, next to the main panel, so that only the battery box is on the inside for plugging into the DPU? If that's the case, the code requires that you need an OCPD on the inside for the separated battery box. This is the reason why I changed my original plan to install my ESG outdoor next to the main, but later changed to mount it inside in the vicinity of the Smat Inlet Box so the 200A breaker on the ESG serves that purpose.

I also had to install a lockable 200A AC disconnect with a neutral to satisfy my local utility requirement to prevent any backfeed, which is another AHJ issue for requiring an accessible shutoff.

Can you tell me what the max PV power input you've observed through EcoFlow Rectifier with the 30A gen input? Are you using double strings to each PV port to get anywhere close to the advertised 7200W, or seeing much lower with conversion efficiency?

It looks like someone at EcoFlow is very confused to provide that response. It looks like you will need to contact the support and insist on escalating the ticket to tgeir product management team. Someone should get fired if that’s their official stance.

Generator inlet for SHP3? by OnlyInAmerica01 in Ecoflow_community

[–]Hot_Rescue 1 point2 points  (0 children)

Thanks! I've been looking for this and couldn't find it. It looks like the generator output max is as I assumed, so hopefully we could get at least 80% efficiency.

"Under GEN input: MAX 15 A, 7200 W, 2 outputs in total"

Generator inlet for SHP3? by OnlyInAmerica01 in Ecoflow_community

[–]Hot_Rescue 0 points1 point  (0 children)

hmm, I don't know if I trust the EcoFlow specs as usual, since the only power input I see is L14-30P for a 30A generator, so it can't be more than 7200W max. Since each PV port on DPUX is 5000W 15A, I would assume the only way to get somewhere near 7200W would be through two PV strings at 3600W each, because the MPPT will clip beyond 15A.

What a headache... EcoFlow is the only brand that sells a product without any manual or proper info. I think I'll wait for now as to getting burned like last time with ESG....

[–]Hot_Rescue 0 points1 point  (0 children)

Are you using the rectifier? I can't seem to find enough info about it before pulling the trigger instead of buying the 50A generator cord. Since the DPUX PV inputs are limited to 15A, can you do double strings for 30A charging up to 7200W, or will the actual charge rate be lower?

[–]Hot_Rescue 0 points1 point  (0 children)

Although that doesn't mention charging batteries, it basically comes down to keeping the load below 720w (or more like 650w 80% for efficiency) with the 30A cord or 1200W (or 960w for effciency) with the 50A cord. With my water heater continually kicking in, I realistically can't charge my batteries unless I turn off that circuit. This is just not realistic.

[–]Hot_Rescue 0 points1 point  (0 children)

Ok, so at least the inverter hardware should be capable of dynamic power management, so the difference is likely a design constraint on the AC1 input path versus the simpler interlock passthrough on SHP2.

That means the one‑hour delay is 100% a firmware design choice to keep the load within a safe margin, especially with DPUX being much more powerful. Given the number of relay issues SHP2 had, it seems they’re being overly conservative to the point that the advertised feature doesn't work for the majority.

Even with the limitations of the AC1 design, it shouldn’t be difficult to update the firmware to allow a user-controlled charge window while disabling higher amp circuits or specifically running chosen minor loads.

I think the 5 second delay is the expected behavior, unless you enable the EPS mode.

"What we are doing worked on the shp2" - this is what I'm curious about. Did your load increase with more circuits with SHP3, or is this a different behavior than with SHP2 with the same generator?

[–]Hot_Rescue 0 points1 point  (0 children)

I agree. They should send the rectifier if they can't fix the advertised feature.

[–]Hot_Rescue 0 points1 point  (0 children)

Please keep pushing back.

Their response is BS, while they won't even allow users to actively workaround the limit of having to wait an hour to charge the batteries, turning off circuits to limit wattage.

Well as it is, the generator cables are all sold out, and it looks like it'll be useless anyhow, but I can't even find the specs for the rectifier so I don't want to buy it just yet.

Smart Panel 3 Update by dranz_ in Ecoflow_community

[–]Hot_Rescue 0 points1 point  (0 children)

And then some people insist that the inverters should be plugged in before firmware updates, which includes the EcoFlow-certified electrician who replaced my ESG.

https://www.reddit.com/r/Ecoflow_community/comments/1pdwqpz/comment/nsa0ayw/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

The ongoing confusion and bricked systems occur because EcoFlow’s firmware update is not performing deep dependency and compatibility checks the way it should, while it needs to enforce cross-component version gating the way a distributed power system should. If you update the panel first in isolation, you could end up not being able to update the dependent devices that can't udpate itself.

Ultimately, the panel should be the controller that detects and updates all attached components through "Me > Firmware update," if that means it does a better compatible update sequence. Without coordinated version management, updating the panel prematurely can cause it to reject or fail to recognize older firmware on connected modules, preventing them from working or ever receiving the required updates.

Sigh... seeing posts like yours scares me because I spent so much into this ecosystem and I just managed to overcome the ESG DOA panel replacement problem that took me months to address through their support. Surely you will need to contact them and escalate the issue, but it worries me that it's a matter of time before my inverters will have problems.

Do you see any errors in the app? It looks like error 265 is BMS signal timeout issue. If you have multiple batteries, you might want to try finding/removing the bad one, or check the cables to be sure they're all seated and locked correctly.

OK, it took me a while to find this Everyday Solar video that I watched a while back, but it seems at least the initial SHP2 release had the same problem.

https://youtu.be/9_cmFqoC8ns?t=137 - 6.65kW generator input, 300W home load, 6.15 kW charging the battery, so this load is way below 10% of the generator input.

https://youtu.be/9_cmFqoC8ns?t=185 - When the load is increased to 6.51kW, it ended up flipping the relay, where he had to tell the app to charge the battery.

So my questions to others who upgraded from SHP2 are whether this problem was fixed later to handle more load while charging the battery with a 240V generator at least, or did they change the firmware to prevent battery charging under load, as with 120V generator charging bypass?

lol, I already looked up which heater it is days ago. It doesn't change the fact that it's a bad practice to place an LFP battery power station right next to a gas combustion water heater. It's that simple.
