EG4 18kPV Q+A general thread

Correct 1010 an 1110 were specifically setup to disconnect grid relays, To meet the requirements of those with grid connection that their utility strictly forbids grid feedback
oddly that doesn't seem to be the issue with ver 1312 but just displaying it as if it was coming from the grid, even though its clearly showing it coming from batteries and panels. i guess i will let it run overnight too see if it tries putting power to grid. do you know what the new micro grid option is now?

1312. Does appear to mixup data points. It confuses pull from grid or batteries when it's clearly not coming or going from /to grid.

the last entry in the change log for firmware was 12.12 so seems there is at least one more for 13.12 anyone have that?
My understanding - 1312 was an attempt to fix the "glitchy" numbers that were reported in 1212, 1312 is nearly identical to 1212 and unfortunately the glitchy reporting still exists in 1312 that I saw in 1212.

I killed the grid connection at the meter and everything continued on fine on battery and PV but now it is raining hard and dark but the graphic updated to back up. so i guess its just a detector now for voltage if grid is up or down. but operation is same as 1011.

I wish would get get a faster sampling rate. After using solar assistant and emporia vue the refresh is horrible on this you get to see what it thinks it was using for that second for several minutes I find myself checking my emporia for verification several times a day the eg4 monitor will show 1.6kwh or something similar of export but the vue will only show like 50wh for the day. Since i still have a full mechanical meter ive sat and watched it and the vue shows what it actually doing a lot better.

I've noticed the same.
 
Gilbert had to move mine back to 1110, now it works fine again, but I experienced the same after updating. Perhaps some notes on which version to use depending on use case.
makes no sense if these programers know what they are doing why would you lose features fixed in earlier version (zero grid export) when you do an update unless you keep starting with a very old version instead of fixing things in the last version to the next version.
 
ok so this 13.12 firmware moved in steps it seems. as first thing it does when the grid returns is run the entire house from the grid. ignoring the PV and battery. then it adds those to the mix but leaves grid in as step two. then 5 min more it returns to off just solar and battery again. see below...look at times. so it used a few tenths of a kwh from grid to get back to where it should be. that is what Gilbert said it would do.

You can shorten the time. I set mine to 120 seconds.

I feel that it should do the reverse...stay disconnected from grid for the specified amount of time.

I get what you are saying, I thought the same. But they are trying to fix different use cases. For me 1110 works best. I don't want grid feed in during peak hours. It works perfectly. When I had the most recent firmware, it operated as you described. I had to shut grid power down.

i am not actually seeing anything really going into the grid. when you watch on the inverter screen which updates much faster those steps happen in under 21 seconds, it does show a flow to the grid for a few seconds but I show no export on the graphs or totals on phone app it was just freaking me out a bit. It has been on grid but running from pv and now battery fine. the only flaws i see in this version is now shows going to house icon when its really on standby power and in the transfers of grid off and then on (3 x), it pulled .6kw of grid power that it didn't need to (as PV and Batteries where full) but that is minimal (only .2kw per). I think Zapper77 is right they have the priority reversed. if the pv can carry the load then don't use grid period, or if PV and/or Battery can carry the load don't use grid. They start using grid then seem to test the other energy sources one by one before deciding to kill the grid feed. Lets see how it does when batteries hit 15% tonight and goes back to grid for a recharge of 2kw. we will know if the morning. ??
 
Well it is not as good as 1011 as it still seems to bounce when it makes the transition back to batteries and PV from the grid. see in pic 1011 does not show that bounce so not sure what is causing that but no feed back to grid which was my main concern.

here you can see it do it on the app. restarted feeding from grid when load jumps up. so must be calculated to do that based on battery start and PV input being so low at this hour as it was early and we have a storm right now too.

so its official this new firmware does not work correctly and i want to revert but i think Gilbert is asleep in Hawaii at this hour so maybe Marcus is up and about? it not only bounces back and forth it started to export again with. that function disabled. see below. i killed the grid feed but still it exported some. no reason to be on the grid it just decided to bring in the grid anyway...... this sucks... is it 10.11 or 11.11 that i want togo back to if you all know,
