We are quite pleased to carry the 'Doc Wattson' digital panel meter! The Doc Wattson meter is an excellent digital meter for use with DC power systems. We use them to monitor our wind turbines and our diesel back up generator with excellent results. It's quite handy to have one on every power source for basic data aquisition.
The meter displays 7 values. It constantly displays:
-Watts (0 -6554)
And then it toggles through:
-Accumulated kWh (0-650)
-Accumulated Amph hours (0-6554)
It is powered by the battery bank. Inside is built in a 100 amp .001 ohm shunt so connection to the system could not be simpler.
It comes provided with a detailed manual. We find that for DC power systems between 12 and 48V this meter does all you need to monitor any single source, or load. We think it is the best bang for the buck currently for basic system monitoring.
