The Baintech watt meter allows you to closely monitor how much charge your solar panels are producing. 
 
 
 
 
Simple to connect: simply plug your regulated solar source to the 'source' side of the watt meter, and your battery/load to the 'Load' Anderson connector.
 
 
 
 
 
Once connected and power is flowing through, the watt mater will give you real time readings of:
 
 
 
 
 

	
	
Current (Amps/A)
	
	
	
	
Voltage (Volts/V)
	
	
	
	
Power (Watts/W)
