Frequently Asked Questions
What is an electric sub meter?
An electric sub meter measures energy usage for specific circuits or tenants independently. It allows property owners to bill based on actual consumption rather than shared estimates. This ensures fair distribution of costs across units.
How do I install a sub meter?
Install requires turning off power to your panel. Connect line and load terminals according to the wiring diagram. Ensure compatibility with your socket type and secure all connections tightly for safety.
Can sub meters track solar power?
Some models support import and export monitoring for solar. This allows tracking of power generated versus consumed. Look for meters with bidirectional measurement for hybrid systems.
What is the difference between Form 2S and Din rail?
Form 2S meters plug into standard meter sockets, common in rental properties. Din rail meters mount inside panels on rails. Form 2S is easier to replace, while Din rail suits tight spaces.
How accurate are digital sub meters?
Most digital models offer high accuracy, some meeting revenue grade standards. They typically have accuracy ratings around 0.5 percent. Regular calibration ensures they remain precise over time.
Do sub meters require internet?
Basic models work offline with local displays. Advanced ones use Modbus or cloud gateways for remote access. Internet is optional unless you need cloud data integration.
Can I use a sub meter outdoors?
Only models rated for outdoor use or housed in waterproof enclosures should be used outside. Most require indoor installation to prevent moisture damage. Check the enclosure rating before outdoor deployment.
How do I read a sub meter?
Check the LCD display for kWh totals. Cycle through screens to view current draw or power factor. Some units use pulse indicators to show real-time usage activity.
