Recenely had our meter changed to a smart meter and I've noiticed the battery is sitting in Standby mode and not charging/discharging. Presenty its 74% charged and doing nothing !

I presume the power outage has upset something.

Any suggestions on how to peruade it to start charging again ? excess power is being exported at the moment.

Most common problem after a smart meter change is the engineer either forgets to clip on the CT clamp, puts it on backwards or puts it back on the wrong cable.

If you look at your meter there should be a small clamp clipped round the live output of your smart meter - might be worth posting a photo of your meter cupboard if it’s not there or if it has been put back on in reverse your house load will be showing as negative (in which case unclip it and reverse the direction).

Hey, has this issue been resolved?. I have the same problem since the app update. Battery sits in standby mode and refuses to charge unless forced charged by increasing the min soc settings. Would appreciate if anyone know how to fix this. Thanks

Has this happened since you had a smart meter installed?

Nah, I already had smart meters. ..

We can rule out a moved CT clamp then.

Best post up some more information, do you use the FoxCloud2.0 App on your phone, if yes some screenshots will assist.

Attaching screen shot from app and inverter. If u have suggestions for app settings, I will appreciate it very much.
Thanks!

Ok, I think I figured out the problem and resolved the issue. Willtest through for the day.... If u have this issue then flick through the settings on the inverter and disable standby mode... ahah

A home can't import -7kW, so a CT clamp is most likely on the wrong wire or in the wrong direction.

It is best when you can solve it yourself, as you learn things for certain.
Now you woke the beast, let's hope your house is showing the correct polarity and not -7kW.

Let us know if that is resolved.

All good. I had been away for a week and inverter went into standby mode after 5 days. Not sure if this is some default code for idle battery protection. Not sure why it did not auto switch to normal mode upon active use. But all good, fingers crossed. BTW, there is no support from installers who are basically fly by night operators. Hope this is not another pink batt gate...

Sounds good @Jag
Not so good about the installers.

There have been firmware updates happening from Fox and this could have been yet another issue triggered by that.

Yes, excellent communication until the cash is handed over.

Yes it was very tragic that 4 apprentices were killed while in ceilings when it was too hot and unsafe just because companies wanted to ride that gravy train, and I'm pretty sure there were house fires where down lights had insulation to close to them.

However given the government figures say there has been 250,000 installations since July under the current programme it could potentially be even worst than that as 3% of inspected installs are completely unsafe and all lithium batteries have the potential to go up in smoke and take what ever is close by with them as well.

All the firies can do is try and limit the fire spreading because lithium fires burn too hot for water to extinguish them.

Lithium fires regularly make the TV news because it caused the house to burn down, or a garbage truck had to dump it's load in the middle of the street so the truck doesn't get written off, or when portable batteries experience thermal runaway on planes filling the cabin with toxic fumes.

That said those fires aren't typically caused by LFP batteries, the chemistry used in batteries made by Fox ESS, and the batteries causing house fires are directly shipped from China, which means they don't need to meet minimum safety standards that importers must.

The other causes are when using chargers not made for those batteries and charging batteries with physical damage, which is why some installers require bollards to be installed near areas where cars can be driven.

Hear hear... I hope foxess updates the inverter firmware for auto switch between standby and normal.
And I hope the Govt does at least 5% of random independent inspections for battery system installs simply because of the long tail on the systems with high fire risks and sus quality controls on the various accessorial components.
Hope all is well and i get 10years out of my system to make it financially viable.

I'm not sure how many inspections have been done, but the same thing happened when solar systems were first rebated, because the majority of sparkies were only used to AC wiring. I think the failed inspections were about 10% at the time.

Well I worked out with the current Globird ZeroHero plan that if we don't export we'll pay off the battery in ~5 yrs due to savings on power bills.

I don't expect the simple math I did to hold for 5 years straight as power plans are always changing and of course power prices will only ever go up.

If you do plan to export at least 7.2kWh between 6pm to 8pm the pay back will be even sooner as that's the point where our bills start to be negative. Although winter will be another matter when it comes to spare amounts of power.

Another thing I'm still tuning is the Grid/Meter Compensation as we are still importing very small amounts of power during the shoulder and peak times.

Monday's usage was 4c with a setting of -50W, yesterday it was 3c with a -60W setting, dropped it to -70W this morning and will find out tomorrow if it's enough.

According to the math It's better to export a little bit than import electricity at the wrong time of day.
