Battery/Inverter issue

#1 Dave56 2023-10-15

For a while now I have had issues. The issue isn’t continuous but all can be fine for week or so than have one day or two day issues.
The issue is that ( it is always overnight or early morning) there is plenty % in battery but instead of taking from battery it takes from grid, obviously at my cost. I have emailed GivEnergy, they did an update saying should sort it but didn’t. Now saying another update may help it. He tried to do the update but couldn’t.He sent me a long winded email explaining how I can do it, sorry but this is far too technical for me.
Apparently all settings are okay, however I need to resolve this. Am I within my rights to ask for GivEnergy to send someone out to look at this.

Hi Dave,

I have as of two days ago had an All-in-One GE system installed. OI have noticed the same thing, overnight I am getting power off the grid when my battery is sitting at 56%, equally, I am exporting to the grid over night !!

I'll be ringing the installer and GE in the morining - bizzarre

If the grid voltage goes above about 253V, the inverter will stop outputting, resulting in the symptoms that you describe.

This Android app can monitor the grid voltage at the inverter.
