As of 1 April 2026, if you have a single phase domestic connection, you can export up to 10 kW of electricity generated from your solar system back to Top Energy’s network, up from our previous standard 5 kw export limit.
To be considered eligible for this increase, your system must meet our technical requirements :
- Be connected via a single-phase domestic connection,
- Maintain voltage within New Zealand regulatory limits,
- Use an inverter that is compliant with AS/NZS 4777.2:2020 (Australia A) and has volt var, volt watt, and frequency watt functions enabled.
- Comply with the Electricity (Safety) Regulations 2010.
It’s important to note that while the limit has increased, what you can actually export could still be subject to a network assessment based on our network capability.
To increase your existing export limit, please make an application to do so below.
Once approved, a qualified electrician or solar installer will need to physically adjust your inverter to allow it to export up to 10 kW, depending on what your system is capable of.
