Inverter idle

So it seems that my battery is at 100% and the inverter is idle, and all charge is coming from the grid, this has been going on a while but just noticed as I’ve been working away.

I’ve restarted the inverter but still showing idle, is there anything I can check to see what’s going on?

Use the portal (top right corner) to restart the inverter and then make sure Eco is enabled.

SteveCook I have and it is.

So I did an update and the battery went down to 0 then gradually up to 51

I seem to be able to force a charge and a discharge, but eco doesn’t seem to do what it’s supposed to 🙁

I had the same problem. Via the App., navigate to 'inverter settings' --> battery options' and check the status of 'discharge power'. Upon first inspection and not sure how, 'discharge power' was set to zero. I increased it to 100% and the battery resumed service.

I should add, I have 'eco mode' enabled and this setting remined unchanged throughout.

I hope this helps

Thanks, but that’s set ok too, I think it may be calibrating as it happens as the battery level continues to climb but doesn’t show as charging.

No idea where to check and no idea how long that lasts

shawry you should get a notification in the portal if the inverter is calibrating the battery

The other thing to try is a ‘reset to defaults’ in the portal if Eco mode isn’t working properly

No notification that I can find, only indication is in predbat where the state is sat as calibration.

I’m forcing a charge (as currently shows 58%)and then will force a discharge only because otherwise I’m sat with a full battery doing nothing 🙁

shawry only indication is in predbat where the state is sat as calibration.

An easy way to check if the battery is calibrating is to use the Android Inverter Monitor app, tap the battery line, and if the calibration stage is not zero, then it is calibrating.

shawry If Predbat is reporting the battery as calibrating and the battery level is rising but its not showing as charging, then the battery definitely sounds like it is doing a calibration. You won’t be able to force a charge or discharge, only change the charge/discharge rate, until the calibration is finished.

geoffreycoan problem is its still calibrating and I guess the issue is because it doesn’t show in the portal means it’s stuck somehow. I’ve emailed givenergy and my installer hopefully they can do something to sort.

Just means that my costs are going to be higher due to not using the battery to power the house, I can offset some by discharging I guess

Turn everything off (open all breakers)
PV DC string breakers
Consumer unit mains feed
Turn off battery (on 9.5 button high on RHS)
DC breaker from battery feeding inverter.
Let everything sit for 30 seconds so inverter is fully dead.

Turn everything back on and it should all reboot

shawry I’ve emailed givenergy and my installer hopefully they can do something to sort.

If you're running HA and predbat, you really need to turn all that off to establish it's a problem with the inverter.

DD I have done and its still the same, HA was the thing that flags it calibrating, nothing else shows it, once it did that I turned off HA as its all I use it for and it doesnt do anything while calibrating

SteveCook this doesnt seem to have worked either 🙁

Thanks everyone for trying to help

So until installer/givenergy get back to me I have set a manual charge for 23:30 to 05:30, and a manual discharge from 05:31 to 23:29 with a limited discharge power of 735W that should help mitigate most of my expensive period with minimal supervision required hopefully.

EDIT, though it seems to keep maxing out the discharge power for some reason

Just put the inverter in eco mode and set a timed charge. Don’t set a timed discharge. It’s complicated, so unless you know what you are doing and how to make it work how you want it to work, stick to eco and timed charge for now.

Have a look at the activity log at the bottom of the remote control page on the portal. That should log any changes made to the configuration - now it even spots changes made locally over modbus.

If it is doing a calibration, best to turn off timed charge and discharge and let it get on with it. All will return to normal once the calibration is done. What stage is it at?

Rubikcube the issue I have is it doesn’t say it’s doing a calibration, the only indication I have is that it says that in HA.

And I left it as is for over 12 hours and it didn’t change in HA and the battery didn’t help with powering the house (though does on forced export)

My installer spoke with Givenergy, it appears that I had a stuck calibration that wasnt showing, this was cleared, now all working again 🙂
