You just have to set it up to always import some power.

I don't mind it pulling a couple of watts to make sure it is synced to grid, but mine is powering the loads too. As soon as grid is turned off it powers the loads from battery.

video on export/import best settings and results is in the works from @BraydenFromEG4

next week or two

Frankly, if it can not handle those two cases I mentioned above properly then I don't know how something could be UL1741 certified.

Or CEC or whatever that California certification is that it just got apparently.

James you need to get on this now not in the next week or two. It's blooming into a pretty serious issue for a few of us and this is how other shit storms have caused you reputational harm in the past.

UL1741 is anti-islanding meaning that if AC input is dead it will not energize it.

Sounds like a settings issue. Hopefully, more information will come about settings.

Is @JacksonSolar simply saying he is going to remotely change a setting that @rmacgurn could change as well if he knew what to change?

yes

Can the explanation of what to change not be posted here? If not because it is too complicated then would have suggestion to update firmware to make it a single click option in the UI to do the equivalent.

My meter shows 21-39w load from the grid most of the time.

That's probably not enough to keep any surge or slump from causing a momentary export.

not sure I follow this but since I am trying to run with as little as possible grid input and zero grid export you saying to use the peak shaving option to allow only limited power say .1kw (the smallest allowed) as input from grid during say 7am to 5pm then the other time since solar is down to almost nothing it has nothing to export except battery and export is turned off so it should stop the constant in/out fluctuations I am seeing,
is that correct?

I don't think it works this way - since the inverter uses the batteries to provide power even when the solar is offline

So you still risk during the night back feeding into the grid.

Maybe someone from signature solar should chime in an explain the Grid Peak-Shaving and the Zero Export feature.

From my understanding how the systems works - Grid Peak Shaving - should be a setting under Zero Export. Basically - to trim the risk of exporting under "zero export."

That should be reflected in your name.

Would be nice.

I was thinking the same.

Maybe add a safety buffer to increase grid feed in but only when demand exceeds 4K watts. It would be interesting to see if the users that have this issue have a large 6K load like Air-conditioning that cuts off all a once.

You should be able to change it.

BTW, big deal move for Lifepower4 users

in our closed-loop tests, the Lifepower4 have exceeded lifecycle expectations by 50%
