Description
Growatt 3-phase meter CT250A – energy meter / smart meter
Growatt 3-phase meter CT250A – energy meter / smart meter for Growatt photovoltaic systems. A smart meter measures the flow of energy between the photovoltaic installation, the grid and the loads. It provides the inverter with the data needed to manage self-consumption, battery charging and export limitation (the zero-export function).
Expert commentary
“The Growatt 3-phase meter CT250A is a component that affects correct operation of the whole installation — which is why we pay close attention to matching it to the specific Growatt devices. We are happy to confirm compatibility with your inverter or energy storage system before purchase, to avoid mistakes and extra costs.”

What the Growatt 3-phase meter CT250A is for
A smart meter measures the flow of energy between the photovoltaic installation, the grid and the loads. It provides the inverter with the data needed to manage self-consumption, battery charging and export limitation (the zero-export function).
Compatibility
The Growatt 3-phase meter CT250A is designed to work with Growatt inverters (on-grid and hybrid) that require energy metering at the grid connection point. Matching the accessory to the specific device model is essential — the wrong accessory may not work or may limit the functions of the system. We will confirm compatibility with your inverter or energy storage system before purchase (write to info@growatt.tech). You can browse the full range of devices in the shop.
Why the Growatt 3-phase meter CT250A matters in the installation
Without a correctly installed meter the inverter cannot manage self-consumption or zero-export — it is a key component of the installation. In practice this is the component that determines whether the photovoltaic installation delivers its intended functions — self-consumption, monitoring, emergency power or safe management of the energy storage system. That is why it should be selected deliberately, not by chance.
Installation and commissioning
The Growatt 3-phase meter CT250A is installed by a qualified installer according to the manufacturer’s instructions and the wiring diagram of the specific inverter or energy storage system. Once connected, the device becomes part of a system monitored in the ShinePhone app and the ShineServer portal. Correct installation is a condition of keeping the warranty and of safe, trouble-free operation.
