Common Reading Difference Explanation (U*I ≠ Display Power)

Displayed reading is Active Power (P, unit W), while U×I is Apparent Power (S, VA). Formula: P = U × I × cosφ (power factor). 1. Pure resistive loads (heater, incandescent lamp): cosφ ≈ 1, P close to U×I; 2. Inductive / capacitive loads (refrigerator, TV, PC): cosφ 0~1, active power will be lower than U×I calculation result.

Application Scenarios

• PV solar energy storage power statistics
• Home / rental house electricity consumption monitoring
• Laboratory appliance aging test bench
• Industrial cabinet & equipment power monitoring
• DIY electronic projects & repair workshop testing

Safety & Wiring Reminders

1. Indoor use only; strictly prohibited for outdoor wet environment.
2. Do not exceed the maximum 100 A / 22 kW rated load to avoid burnout.
3. Follow standard wiring sequence strictly; wrong wiring causes module damage.
4. Cut off grid power before wiring installation.
5. Regularly check CT transformer for loose contact during long-time operation.

Frequently Asked Questions

Q1 Why displayed power is lower than voltage × current calculation?

A1 The meter measures active power with power factor correction; inductive loads reduce active power value.

Q2 Does this meter need an external power adapter?

A1 No, it takes power directly from the AC grid circuit.

Q3 Will energy data be lost after power failure?

A1 Built power-off memory function stores cumulative energy permanently.

Q4 What’s the maximum supported load power?

A1 Max 22 kW / 100 A resistive AC load.
