Growatt GROW-SPM-CT-E – Single Phase Smart Energy Meter

Growatt GROW-SPM-CT-E: The Intelligent Energy Meter for Single-Phase Solar Systems

Designed to work seamlessly with Growatt’s single-phase hybrid inverters, the GROW-SPM-CT-E smart meter helps users take full control of their solar generation, export limits, and home energy usage. Whether you're working within DNO constraints or aiming to boost your self-consumption, this meter is a compact but vital addition to your solar setup.

Accurate Real-Time Energy Monitoring

The SPM-CT-E offers real-time visibility into your home’s energy consumption and solar production. Using CT (current transformer) technology, it delivers precise data essential for optimising energy use and monitoring performance.

• Single-phase CT clamp monitoring
• Live feedback for better energy decisions
• Helps balance load and generation efficiently

Perfect Pairing with Growatt Hybrid Inverters

This meter is fully compatible with Growatt MIN-XH hybrid inverter models such as the MIN 2500-TL-XH and MIN 5000-TL-XH. It enables crucial functions like export limitation and energy management to comply with local DNO requirements and boost system efficiency.

Supports Smart Tariffs and Self-Consumption

With precise energy data, users can adjust their usage to align with off-peak tariffs or maximise the use of generated solar power. When used alongside a Growatt inverter and battery, the SPM-CT-E helps increase the amount of free energy used on-site, reducing grid reliance and electricity bills.
