12000XP leaking power to the grid?

I just saw a FB post indicating that a 12000XP user got a report from their Poco they were leaking 2 watts occasionally to the grid.

First I have heard of that. Anyone else hear this?

Someone mentioned adding a light bulb to soak up that wattage. Where would you put that? Alligator clip to both lines going to the grid inside of the 12000xp? Or would it better to put that by the breaker it draws it's grid power from?

There's a reason they are called BetaBoxes. 🤷‍♂️
 
They've got a reputation for their products getting rushed to market or firmware for their products getting pushed without fully testing hence "Beta Box" They'll possibly get issues solved eventually. In their defense it seems to be a commono theme inverters back feeding when not supposed to. Just the nature of the physics of it where you need to always be pulling some power from the grid to prevent backfeed when you turn a large load off. Chargeverter would probably be the easiest way to stop the possibility of backfeed.
 
Had my 6000xp hooked that way for 2 years never heard a peep from them. I just connected up a Emporia energy monitor it has an option for solar. I wonder if it can see anything going the other way.

I notice that I can grid charge while solar is charging it combines the two loads are grid only. I wonder if there is some thing going on there.

Can you explain how this is not an issue when using a large inductive load like, say, a dryer. Doesn't that backfeed to grid at least briefly when its demand lowers or am I completely wrong?
 
It was only a few watts apparently. I doubt it could backfeed anything more. But EG4 isn't shy about saying you might not need an interconnect agreement. A few watts back to the Poco is likely enough to make them encourage you to get one. With a carrot or a stick though?

I noticed my 12000XP was showing it was sending some wattage to EPS when I had no power drawing from it. I don't believe the idle consumption of the inverter shows up under EPS. I believe that is a draw from battery/solar only. I shut my breakers completely off if that's the case. I don't want to risk back feeding the grid. They have wireless back feeder and fault sensors on their lines now.
 
Get a chargeverter to charge batteries and disconnect the BetaBox from the grid so physically no ability to feed back.

Or, if you don't need 5000 watts of charging, and want to pay a little less, get the eco-worthy version for $300.

What's the minimum watts required to achieve this (pulling some power from the grid)? The EG4 manual says to keep AC battery charge over 0 watts and their example is 0.100kW. Can it be even lower at 50W? 25W? I figure you need some kind of buffer to account for CT inaccuracy.

Not sure. Otherrs with experience with grid connected will have to chime in.
 
I have been considering purchasing the 12000xp but wouldn't using a chargeverter to prevent back feeding disable the inverter ability to transfer to grid when exceeding its capacity?

IT's an off-grid only inverter I have the 6000xp no way to set it to export to the grid. This post is the first time I have heard of anyone being notified about exporting with this series inverter. It's lot more common with the hybrid inverter since the grid input and inverter output are wired in parallel with the grid.
 
I finally gained approval to that Facebook group the OP said Jason from EG4 resolved it by connecting a 2 watt light bulb there hasn't been any further information the cause or where to connect it. Like if we could hear what was causing this and how the light bulb was connected so we can avoid this issue also. I'm not sure my utility would be so nice about it.

Thank you for following up!

In our country 12000xp is sold as Eco hybrid and it can sell power to the grid, but on the ip65 18kpv you can select zero fast export, but you may send back power in the occasionally because of large loads turning off.
