Battery Won't Fully Discharge

Hi folks,
Solar panels, 9.6kw battery, 2nd gen, latest firmware.
I've just went onto the flux tariff. I set the timed export to discharge fully between 1600-1900.

I noticed last night it discharged to 25% then sat idle.

Just notice its done the same again (discharged to 25% and idle from about 1730).

I checked on the online dashboard and the times export is still on. I went onto the android app and set it to force discharge but it's still just sitting idle at 25%.

Any ideas what's going on?
Cheers

Do you have a power reserve set for EPS ?

Hi mate,

I've attached a screenshot of the bit I think you're talking about. I've not long had this instaled, so very much still a 'newbie'

I've reset it to default settings a couple of times, but still sitting idle at 25% and when I try to force discharge or set export times after resetting back to defaults, it is still sitting idle at 25%

Try the battery cutoff % one. That one does persist after a reset to default I think so could be what's stopping it.

Hi mate, excuse my ignorance, what are you thinking I should set the battery cut-off % to?

Thanks

Scottishcammy default is set to 4% (it won't go any lower anyway.
If yours is 25% that is why it's stopping.

I see what you mean. Unfortunately, it's set to zero. I'll have to phone givenergy on Monday and see if I can get a resolution.

Scottishcammy will it not change at all? You normally force it by setting the slider then clicking the '>' arrow to send?

It stops discharging when it reaches 25%.
Even if I do it manually by forced discharge in the app, it just sits idle at 25%.
As soon as I resume it to normal operation, it will supply power to the house as normal, but I cannot get it to discharge to the grid past 25% whatever I do 🤷🏻‍♂️

Scottishcammy The suggestion is that regardless of what it says it is set to, try setting it to say 10% and see if this cures the problem. The value may have got corrupted on the inverter. It should be 4% not 0%.

Thanks mate, I'll give that a go 👍

Tried setting the discharge limit to 4% and it stopped discharging at 25% again.

Managed to work it out eventually though, so hopefully helps anyone else who might find themselves in the same situation:

In the remote control section of the inverter:
in the section 'DC Discharge 1 Lower SOC % Limit" and the section immediately to the right of it:

If you simply put the section to the right to 4% it looks like it accepts it. However, when I did that, it didn't work.
When I was trying to work it out tonight, I clicked the refresh icon in the 'DC Discharge 1 Lower SOC % Limit" and the percentage field in the section to the right immediately went to 25%.

I changed it to 4% and seems to be working. It must be set to 25% but hidden from normal view. Goodness knows why...

Screenshot attached, hope it helps someone, and thanks for the advice.

Always hit the refresh button on any parameter when using the portal as the displayed value is often out of date/wrong

Thanks, had my installation for a couple of weeks with exactly this problem. Why on earth is it set to 25% on a battery that supposedly has a 100% discharge? Found the page after a lot of looking and it's now set to 4% so hopefully it will now fully discharge.

athresuk I learned this the hard way and it stressed me out to no end lol
