AC Power Consumption Meter – Plug-In Wattmeter / Energy Monitor (kWh, Watts, Voltage, Cost)

Stop Guessing. Start Measuring.

The number one reason solar systems disappoint in Nigeria isn’t the batteries or panels — it’s bad load estimation. When you guess how much power your appliances use, you end up with a system that’s either too big (wasted money) or too small (wasted opportunity).

This plug-in power meter solves that problem for a fraction of the cost.

What It Measures:

• Watts (W) — Real-time power draw of your appliance right now
• Kilowatt-Hours (kWh) — Total energy consumed over time (the number you need for solar sizing)
• Voltage (V) — Actual mains voltage (useful for diagnosing PHCN fluctuations)
• Current (A) — Amperage draw
• Frequency (Hz) — Power supply frequency
• Power Factor — Efficiency of power usage (cos φ)
• Cost (₦) — Programmable tariff rate calculates actual cost per appliance

How to Use It:

1. Plug the meter into your wall socket
2. Plug your appliance into the meter
3. Read the display — buttons cycle through all parameters

Leave it on your fridge for 24 hours to get actual daily consumption. Move it to each appliance over a week, and you’ll have a complete, accurate load profile for solar system sizing.

Features:

• Large LCD display with clear readings
• History function: track daily, weekly, and monthly consumption
• Overload warning indicator
• Memory retention during power outages
• Negligible self-consumption (< 0.5W)

Technical Specifications:

• Power measurement range: 0 – 3,680W
• Voltage: 230V AC (±10%)
• Current range: 0 – 16A
• Energy range: 0.000 – 9,999.9 kWh
• Frequency: 50Hz / 60Hz
• Plug type: Compatible with Nigerian sockets

Practical Uses:

• Size a solar + battery system based on real data instead of estimates
• Find which appliances drain your prepaid meter fastest
• Compare old vs new appliance efficiency before replacing
• Monitor generator fuel efficiency per appliance
• Verify that “energy saving” appliances actually save energy
