By Casey Midgley, Arlite Energy Last reviewed 30 October 2026 4 minute read **No DIY.** Electrical work must be done by a licensed electrician. Never open, repair, test or modify electrical equipment yourself, even if it looks simple. This guide explains what is happening; it is not a how-to. **On this page** 1. Why does a limit exist? 2. What are dynamic connections? 3. What if my system loses communication? 4. How can I tell a limit from a fault? 5. What to gather before asking your installer 6. Should I do anything about a limit? 7. Frequently asked questions Your network provider limits how much solar power your home can send to the grid, to keep local voltage stable. In South East Queensland that is Energex. Dynamic connections can raise the limit when the network has room, and it falls back to a default if communication is lost. Usually it is a rule, not a fault. ## Why does a limit exist? The local network was built to carry power to homes, not to take large amounts back from thousands of rooftop systems at once. On a sunny afternoon many systems export together, which can push voltage above safe levels. Export limits keep the network stable and protect equipment, including yours. ## What are dynamic connections? Energex has a program called dynamic connections that can allow higher export limits when the network can handle it. Energex explains how it works for homeowners on [its website](https://www.energex.com.au/our-services/connections/residential-and-commercial-connections/solar-connections-and-other-technologies/dynamic-connections-for-energy-exports/homeowners-and-small-business). The limit can vary with network conditions and is set per phase, so what applies to your home depends on your connection and your system. We have not listed specific figures here, because they can change. Your installer, your retailer and the Energex page can confirm the numbers for your property. ## What if my system loses communication? With a dynamic connection, the system relies on a communication link to receive its limit. If that link drops, the system generally reverts to a lower default limit. That can look like a sudden drop in export, even though nothing is physically broken. Your installer can check how your system handles this. When it might be a fault A limit by itself is not dangerous. But if the inverter shows an error, smells of burning, looks scorched or makes unusual noises, keep away from it and keep children and pets away. If there is smoke, sparks or flames, leave the building and call 000. Contact a licensed installer. Do not open the inverter or touch the cabling. ## How can I tell a limit from a fault? A limit usually shows as output levelling off at a ceiling on a sunny day, with no error message and a monitoring app that still reports normal operation. A fault more often brings an error code, a warning light, or output that drops to zero. You can look at your installer's app or portal to see what your system is reporting. If something looks wrong, a licensed installer can diagnose it. Replacing equipment without a diagnosis is not a good idea, because it usually will not change a network limit. ## What to gather before asking your installer 1. What you have noticed — Write down when output drops, how high it gets and whether it happens on clear days. 2. What the app or display shows — Take screenshots of your monitoring app, and photograph the inverter display without touching anything. Note any code. 3. Your connection paperwork — Find your approval or connection documents from the installation, and your retailer details. 4. Make and model — Have the labels or paperwork ready for the inverter and any battery. ## Should I do anything about a limit? Often the answer is nothing. Some households use more of their solar power at home, and some choose a battery to store the surplus, but those decisions depend on your circumstances and your retailer. Your installer can explain the options for your property without anyone having to replace working equipment. If you are unsure whether your system is on a dynamic connection, your connection approval and your installer are the places to look. They can also tell you whether the system relies on an internet or network link to receive its limit, which is useful to know if your internet drops out. ## Frequently asked questions - No. Export limits are set by the network provider and usually mean the system is working as designed. - It depends on your connection and your network provider. Ask your installer and check Energex's page on dynamic connections. - A system with a dynamic connection may fall back to a default limit if its communication link drops. Your installer can check. - Probably not, since the limit comes from the network rules and your connection. Get a diagnosis before buying equipment. - Your network provider, which is Energex in South East Queensland, in line with your connection approval.
