Hi there, I’m new to this and this is my first post.
Ive had solar panels on my roof since 2013 and added an additional system in 2018 so I’m fairly familiar with the workings, management and monitoring of multiple solar systems.
I purchased a EQ4800-L9 battery with a Fox 9.9 Inverter late in December 2025 so I’ve been feeling my way with things. I noticed a couple of weeks back that under the ‘Quick Settings’ tab in the app we had been given the ability to change the ‘Export Limit’ which made sense to me as there could be times that it might be appropriate to vary this setting, but today I’ve noticed that this option has now been withdrawn. Is everyone finding this to have changed or is it only me?
Can anyone shed some light on this change? (is this the place to be asking this question) ?
I’ve seen somewhere in the past that this option might have been limited to ‘Installers’ only and they should be contacted for changes but I’ve had such a disappointing time with my supplier and installers not responding that I doubt that I’d get a response at all from them.

This setting is regulated in most countries and was exposed to Fox users for a brief time between app versions 2.1 and 2.2.3. These settings should only be changed by installers, which is why they were removed from end-user profiles recently.
I understand some users found it useful, but Fox is required to restrict this setting for regulatory reasons.

Thanks for the response, I understand there are regulations that need to be adhered to, and if anyone is silly enough to exceed the regulated limits then you get what you deserve. My issue is when the FIT goes negative as it inevitably will are we all supposed to chase up our happy and helpful ‘installers’ and hope that they will respond quickly, I don’t think so, I’ve been waiting for weeks to get my installer back to fix one of his dodgy connections so my chances of getting him to do a simple change to the Export Limit quickly is likely zero.
I think I’ll take this issue up directly with Fox,

Fox won't budge on this matter.
You are better to look into ways to control your Inverter better going forward.

Yes your probably right but it’s worth a try, either way I’m sure there will be other options.
For now successfully made a change to my Export Limit directly thru the inverter, would be a lot easier if it hadn't been withdrawn in the app.
Yes that is one way to change it.
Serious question, does Australia have a permission notification on how much Import/Export you can have on your lines?
UK we have to have permission and calculations done to tell us our hard limits.
My G99 certificate for example

As far as I’m aware we in Australia don’t have a ‘certification’ as it seems you guys do, solar Export limits vary considerably depending on which state you are in. It’s all a bit complicated.
Here’s some info I just looked up but even this info may have changed:
_________________________
Solar electricity export limits in Australia are primarily set by local Distribution Network Service Providers (DNSPs) rather than state governments, with a standard limit of 5kW per phase (or 1.5kW in some constrained areas) being common for single-phase households.
However, many networks are transitioning to "Flexible Exports" (also known as dynamic exports), which can allow households to export up to 10kW per phase when the grid has capacity.
Solar Export Limits by State and Territory
South Australia (SA Power Networks):
Known for pioneering flexible exports. The standard fixed limit is 1.5kW per phase in many areas, but participating in "Flexible Exports" can raise this to 10kW per phase.
New South Wales (NSW):
Generally, 5kW–10kW per phase, depending on the distributor. Ausgrid (East Sydney, Newcastle) generally allows 10kW per phase, while Essential Energy and Endeavour Energy have a 5kW per phase limit, with 10kW available under flexible, capacity-dependent scenarios.
Victoria:
Generally 5kW per phase (5kW/single phase, 15kW/three-phase), with flexible exports (1.5kW to 5kW) being introduced through distributors like AusNet.
Queensland (Energex/Ergon):
5kW–10kW per phase. Fixed limits are typically 5kW per phase, while flexible exports allow up to 10kW based on network capacity.
Western Australia (Western Power):
A major change starts in May 2026, allowing 30kVA total inverter capacity (combined solar/battery) for standard connections (single and three-phase). Previously, single-phase was often limited to 5kW export.
Tasmania (TasNetworks):
Generally more generous limits of up to 10kW per phase.
Northern Territory (PowerWater):
Typically 5kW for single-phase and 7kW total for three-phase.
Key Concepts Affecting Limits
Flexible Exports (Dynamic Controls): These require a smart inverter and internet connection. They allow higher exports (up to 10kW/phase) most of the time, but reduce exports during peak congestion.
Inverter Capacity vs. Export Limit: You can often install a larger inverter (e.g., 10kW) even if your export limit is lower (e.g., 5kW). The inverter will "throttle" or limit the output to 5kW when necessary.
Zero Export Limits: Some areas with high network congestion, particularly in Victoria and South Australia, may be assigned zero or very low export limits (e.g., 0kW or 1.5kW).
Three-Phase Connections: Generally allow higher export limits, often 3x the single-phase limit (e.g., 15kW–30kW depending on the network).
Note: Solar export rules are highly localized and can change based on the capacity of your specific local transformer. Always check with a local Clean Energy Council accredited installer for the current limit in your area.

Thanks for that, it does help paint a more full picture for sure.
That does complicate the matters with the export limits being locked off, there needs to be a way to dynamically adjust this for certain markets for sure.
With all the VPP stuff going on with Australia, they should perhaps have control of this export limit (if they don't already have access) to change the value for events that occur during demand. So that it is still taken out of the hands of yourselves, but the likes of Amber can change this.
That might be a better way forward if possible.
