What measurements does the SM-US-200 display?
The meter displays voltage, current, active power, cumulative energy, frequency, and power factor. It can show both grid consumption and solar generation if configured for bidirectional use.
Is the SM-US-200 compatible with non-Growatt inverters?
The meter uses standard Modbus protocol (RS485) and can be integrated with many third-party inverters and energy management systems. However, compatibility should be verified with the inverter manufacturer.
How accurate is the energy measurement?
The accuracy is typically ±1% for energy measurement, meeting the requirements for residential and light commercial monitoring. It is calibrated to provide reliable data for billing or analysis.
What do I do if the display shows no data?
First, check that the power adapter is plugged in and the meter is receiving 5V DC. Verify that the CT sensors are properly clipped around the conductors and oriented correctly. If using RS485, ensure the wiring and termination are correct.
Can I use the meter for net metering?
Yes, the SM-US-200 supports bidirectional power measurement, allowing it to track both consumption and generation. It can be configured for net metering applications in solar installations.
How do I clean and maintain the energy meter?
Use a soft, dry cloth to wipe the exterior. Do not use water, solvents, or abrasive cleaners. Keep the meter free from dust and moisture. Periodically check that all connections remain tight.
What are the safety precautions when using the SM-US-200?
Always turn off the main power before installing or removing the meter. Use only the supplied adapter and CT sensors. Do not expose the meter to rain or condensation. Installation must comply with local electrical codes.
Where can I find the user manual and spare parts?
