Hi folks,

I'm going to be moving back to flux from intelligent flux with the change in seasons shortly.

When I was last on it, I seem to remember there was an issue around automating the discharge time between 4-7 and /or keeping eco mode on from memory...
Is this still the case, or has this been fixed?

Thanks folks

Scottishcammy Depends exactly what you mean by "discharge time". In GE terminology, "timed discharge" is a means to hold battery charge until, say, an expensive part of the day, "timed export" is forcing the battery to output power to the grid. (Although unhelpfully, the latter is done through "discharge timers".)

There have been a variety of issues, such as setting the lower bound on any forced exports. Gen-1 inverters can behave a bit differently.

Cheers. The cheap import is 0200-0500, and expensive time is 1600-1900.

So I wanted to set it up so the battery charges 0200-0500 and sell it back to the grid between 1600-1900.

I just remember there were issues when I was trying to do that before, I think it was eco kept switching itself off, but my memory is poor so couldn't recall exactly what it was 😂

Ah, okay, yes...

One thing to note that, while timed discharge has always been described as holding power until needed, in practise, on most inverters, it used to actually behave as "timed export, but without turning off the eco flag". That has now all changed. Timed discharge now actually configures the pause timer to pause discharge when it's not wanted. Timed export shouldn't turn off the eco flag, but on gen-1 inverters (except maybe on the new "fast response firmware) it is actually necessary to turn off eco flag to actually achieve export.

I'd still double-check that configuring a timed-export doesn't turn off the eco flag, though...

I think different Gen inverters behave differently. You may have to search the forum as someone did start a thread trying to table all the commands and what they actually did. I got fed up, got a Pi from my son and installed HA and Predbat and let that take care of all of it. I use Flux in summer and Eco7 in winter (longer off peak charge slot and not much excess solar to sell at peak)

Thanks folks 👍
