Hi - just started on here, so this is all new to me.
Had a Gen 3 9.5kW AC coupled battery installed back in August.
All was working fine until first week in September whilst we were away.
On return discovered that battery wasn’t charging from PV.
It is now Idle and won’t charge from PV or grid.
I have tried a system reboot but this has not worked.
Installer and myself can get no response from GivEnergy.
Can anyone give any more advice?
Thanks
Paul
try. a ‘reset to defaults’ on the givenergy portal
then check your settings are all set correctly. In particular Charge rate, AC charge is enabled, battery pause is not set, reserve is 4%, etc.
If you like post a screenshot of your settings and we can see if we spot anything untoward
Thanks for your reply.
I’ve done a system reset to defaults.
I’ve attached a screenshot of what I think are the relevant settings.
Reserve is set to 4%.
I cannot see settings that refer to AC charge enabled or battery pause. Where might they be?
Thanks again
Paul
Odd that the charge and discharge power are both (only) 250W, I’d expect 3600W
256W seems to be as high as you can set it
Try going to the GivEnergy cloud portal (givenergy.cloud) once there click My Inverter on the left menu bar. Then click Remote Control (the cog wheel) on the right of the screen. This should show you all your settings.
Check the Battery Charge Power and Battery Discharge Power are set to 3600.
Also check Inverter Charge Power Percent and Inverter Discharge Power Percent are both at 100%.
There is a circular arrows to the left of the settings. Click this to force the inverter to read the registers again. Sometimes it shows cached readings and not what is actually set.
Do you have the phone app - you could try checking it in that as well.
no, stick to the cloud portal and use the remote control screen as @NormC has advised, the crucial thing is to click the circular arrows to force the portal to download what the actual inverter settings are from the inverter.
The app and the ‘quick modes’ screens just repeat what the portal thinks the inverter has set, which may be wrong.
The charge and discharge rate maximum of 256W looks very wrong.
If you can paste a copy of the settings on the remote control page (after clicking the little wheels) we can see if anything obvious is wrongly set
Thanks so much for your help folks.
I’ve doe as suggested by @NormC - I cannot set my discharge and charge settings to above 256W (so that is weird).
Screen shot attached.
In other news - installer coming on Friday and has a booked called with GivEnergy to try and sort things out.
Any advice in the meantime would be gratefully received!
Paul
AC charge upper limit should be 100% not 80%, and you can turn ‘enable AC charge upper limit’ off so your inverter uses the full range available
But why the charge and discharge rates are so low, sounds very much like something is misconfigured on the inverter
Hope your installer can spot it
In the top left corner of the Remote Control page is a button ‘Jump To Logs’. This will take you to the bottom of the screen where you can view the ‘Remote Control History’.
Click on the ‘All-Time’ option to display all the commands that have been sent to the inverter. This may give you an insight of what has happened.
If you start from when the inverter was commissioned and come forward through the pages you should be able to see when the values for Battery Charge Power and Battery Discharge Power were changed and who by.
Look under the User heading and under the Via heading to see who made changes and how it was changed.
As @geoffrey says it does look as though something is misconfigured.
Hi again,
From what I can see the Battery Charge/Discharge power was set to 256W when I did a ‘Reset to Defaults’ (my first attempt at trying to sort things and based on some internet research). I did this on the 5th Oct.
Logs also show that server keeps setting and resetting charge and discharge times according to the Cosy tariff settings (I moved to the Cosy Tariff on the 10th Oct). It is changing these setting daily it seems - or is this just the automated command from the integrated tariff?)
I think possibly because the battery is idle it has lost connection with the server though.
Anyway, thanks again for your help.
Let’s see where we get to after installer comes tomorrow
Paul
If you have setup the smart tariff card in the givenergy portal then this will automate charging per your tariff, yes.
As for why your battery rate is that low, very strange.
Hope your installer can fix it
Hi Paul,
Hope you get it resolved tomorrow, please let us know what happens.
Are you using the Smart Tariff Card? If so the server will control your system to follow the tariff you are on.
I am also on Cosy but I do not use the Smart Tariff to control the system. If you look in the Remote Control section of the portal you should see that you can set 10 Charge and Discharge slots yourself.
I never put anything in slot 1. If anything sends messages to your inverter it will overwrite this slot. Such things as Winter Battery Conditioning will do this.
I can then control when I want the battery to charge just by turning on / off ‘AC Charge Enable’.
My PV panels can produce more than I can export so I make sure there is always room in the battery for the surplus.
Your inverter is offline
The battery has a problem, hence the incorrect charge power
Update - installer came on Friday, and managed to speak to GivEnergy Tech support whilst he was here (which was pretty miraculous!)
However we are no further on - he was unable to connect to view the inverter remotely. A change of Dongle didn’t work either.
Very frustrating!
Ok, let the service desk agent know this, if they didnt document already
Thanks. Service desk as in GivEnergy Customer Support?
Just to update - installer managed to sort the problem out this week in communication with tech support at GivEnergy. New dongle and then forced charged battery. Charge power now set at 3kW.
Installer said that number of staff on tech support at GivEnergy has increased.
Thanks for all your suggestions and help on this.
