I use home assistant as well. It's ideal for me. If you're not a data nerd and not paranoid about privacy or security then the eg4 monitoring portal is great. If the eg4 site went down, and you needed to make changes, you'd have to go press buttons like a pilgrim to change settings

Id go with aire for the length thing alone

Go into the settings and set dump-to-ground-rod to true. The electricity will spill out into the ground rod just make sure it's deep cause otherwise it'll make the ground kinda static prone for a while. Obviously make sure you're not touching the ground rod or kinking the wire when you do it

Seems like focusing on deterring vandalism would be better. Cameras if you need them I guess

Isn't that some app where you set the rates and its just displaying what you set?

I have it all connected and it works great. I disconnected the eg4 public cloud IP so I don't bombard their servers, but there's multiple integrations out there, look for the luxpower stuff and you'll find a few, including a guy named Guy who paid a developer to build a pretty robust plugin

DC to DC is probably harder than inverting tbh

Maybe bus limitations somewhere - 250 amps is a lot of juice

I had a similar question earlier. I am not an electrician but I believe you'd either need to wire the load side of the 18kpv to a 125a fused disconnect or 125a breaker with appropriate wire and then step down to something rated for 125a to the critical loads panel.

No I'm talking about the NECs definition of a PCS. Look at the NEC 2020/2023

It's adjustable on the 18kpv

Yep, same. I bumped up the PV start voltage and tada Note: This was a problem before FAB-1717 for me

If an inverter meets the UL1741 spec as a power control system then the 120% backfeed rule can be circumvented as the inverter itself can be programmed to avoid overloading the bus of the main panel. I know the solark has this certification. Any expectations for the eg4?

I'm not sure I follow - you're saying that with AC coupling, you can't use charge last with "seamless switch" because what? voltage changes?

you could pop one open and see if the BMS is from a known mfg, and then go from there Or just open loop 'em and whatever

TBH after trying to write my own charge algo logic for the 18kpv (don't ask), it's far more complicated under the covers than you think. Lots of stuff possibly going on. I know it feels like it should be simple but OTOH you gets lots of knobs to turn

Could you route to a fused disconnect that then runs 4awg to the breaker panel?

What are the IDs on each battery?

I think it would be as it's a current carrying conductor and needs to be in the same conduit/raceway as the hots

That's what I said, it applies to all cloud control planes

Ransomware makes sense if the company or customers have money.

This is my area of expertise. Without eg4 explaining their security practices, we don't know. IMO it's better to detach from the cloud and monitor/manage locally, but I realize this isn't everyone's skill set. Btw I would say the same about any cloud based control plane, especially in this...

I don't really understand your questions

Well, just continuing to monitor, my lifetime charge/discharge efficiency is right around 85% at this point. Not bad. Not amazing. Kind of what you'd expect, I suppose. The few days where it dipped lower than that - I can't really explain still. Maybe ac charging is less efficient? Maybe the...

Cool. Thanks. Easier to help other people when the closure gets documented

What was it set to and what did you increase it to? Kinda makes sense, just wondering.

He said this was happening before PV even entered the story

Yeah none of this feels normal. Sorry, it's probably soured you on the product which for many of us has been a good experience. If Signature Solar could send you an advanced replacement unit, swapping it wouldn't be that hard. Kind of annoying but a 1 for 1 swap of the inverter isn't the worst...

Can you tell us what happened here so other people may know what to look out for if they search?

Hmm. That doesn't seem right and I really don't think it should be needed to isolate your PV ground, but i'm not an EE. It sounds like fundamentally the inverter is broken - i don't know why the PV only works when the batteries are "on" (i assume you mean the breakers on the powerpros), and...

home assistant gang here

Note to anyone else - this information is really annoying (impossible?) to derive from the 18kpv telemetry, so with the 18kpv you're almost forced to tap into the envoy telemetry. Maybe I'm not trying hard enough but it's not there in any of the basic feeds, and may be derived implicitly by the...

Yep this feels like a CT ratio thing now

Can you unclamp one of the CTs from the inputs, then evaluate what your meter says vs the 18kpv for the remaining input? Then re-attach the other CT, detach the first one, and do the same? This gives us some more troubleshooting data that might explain the problem. Also - read your settings...

one of them my be reversed? the CT offset is in the "0-100 watts" range
