Growatt SPM-2CT-C (SPM-2CTA-C-100) single-phase smart meter for Growatt inverters: it measures at the grid connection point so the inverter can enforce zero export and charge the battery from surplus against the home's real consumption. 1P2W grid, 220–240 V, 50/60 Hz, class 1 energy accuracy (voltage and current ±0.5 %). Includes 2 split-core current transformers (CT) up to 100 A with 6 m leads and a 15 m RS485 cable; Modbus RTU. LCD display, DIN-rail mounting, 100 × 36 × 65.5 mm.

FAQ

Which inverters does it work with?

Growatt single-phase inverters: MIN 2500–6000TL-XH/XH2, SPH 3–6K-HUB and SPH/SPM 8–10K-HU, among others with an RS485 meter. We confirm the exact model in the quote.

What is the second CT for?

CT1 goes on the grid supply. CT2 can measure the output of an existing PV inverter (AC-coupled retrofit) so the new system accounts for all production.

What's in the box?

The meter, 2 split-core CTs (100 A, 6 m leads, 16 mm inner diameter) and a 15 m RS485 cable.

Is it needed for zero export?

Yes. Without a meter at the connection point the inverter can't see the home's consumption, so it can't limit grid export or charge the battery from surplus.
