We found this little unit great to measure our incoming solar power versus outgoing battery load on a second unit

Examples of Uses:

How Much Power Does my Fridge Use - with the Battery connected to the SOURCE side and Car Fridge (or other accessory) connected to the LOAD side. The Watt Meter shows the current into the Fridge, voltage and power at the battery and accumulates the Ah and Wh while the fridge is running.

How much charge is going into my battery - With a battery charger (or alternator) connected to the SOURCE side and the aux battery connected to the LOAD side, the Watt Meter shows the charging current into the battery, the voltage and charging power at the battery and accumulates the charge (Ah) and energy (Wh) into the battery.

What is the output of my solar panel  - With a solar panel connected to the SOURCE side and solar regulator connected to the LOAD side, the Watt Meter shows the charging current into the regulator, the voltage and charging power at the solar panel and accumulates the charge (Ah) and energy (Wh) into the regulator.

How much charge is my solar panel putting into my battery - Now with a solar regulator connected to the SOURCE side and battery connected to the LOAD side, the Watt Meter shows the charging current into the battery, the voltage and charging power at the regulator and accumulates the charge (Ah) and energy (Wh) into the battery.

FAQ

Why is the test data wrong?  Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?

Answer: There are three types of power:

Active Power (P represents / unit W)
Reactive power (Q represents / unit Var)
Apparent power (S represents / unit VA)

Here we only talk about Active Power, for others, please google it:

P = U * I * cosφ, cosφ it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time, P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.) P<U*I, As for how much to keep the power factor related to the specific, Different for each appliance power factor.

  • Voltage input range: DC0-25V
  • Voltage detection range: DC0.02445V-25V
  • Voltage analog resolution: 0.00489V

Wiring the DC input connector:
   
  • the positive terminal connected to VCC,
  • the negative  connected to GND
  • Output interface:
  • " " is 5 / 3.3V,
  • "-" then GND,
