Meters

Having a reliable fuel gauge for your alternative energy system is essential. Knowing the status of the batteries and charging system allows you to spot trends and problems before damage occurs. Just as you wouldn’t mount the fuel gauge in the trunk of your car, your system meter should be located somewhere easily visible by everyone.

Digital handheld altimeter

This hand-held altimeter will measure and display current altitude readings, changes between two elevations, and maximum and minimum altitudes. The unit stores altitude data and can indicate changes in altitude for a 12-hour period or calculates the total accumulation of the elevation ascents over a given period of time. In addition, the user can set an altitude alarm that will activate when specified elevations are reached. This unit is also a barometer and can measure and display current ...

Kill a Watt power use meter

Simply plug the Kill-a-watt meter into an AC receptacle and then plug the appliance into the meter. It will assess how efficient - or inefficient your appliance is. A large LCD display with a count consumption by Kilowatt-hours, the same as your local utility. You can then figure out how much that appliance will cost to operate by day, week, month or year.

The Kill A Watt meter also allows you to check the quality of your power by monitoring voltage, line frequency and power factor.

100 amp 100 mV shunt

Shunts are used to measure current. They are accurate, very low resistance resistors. They are connected in series in the circuit in which you wish to measure current. A millivolt meter connected across the terminals of a shunt will accurately reflect the current flowing through that shunt since the voltage drop across the shunt is directly proportional to the current. Shunts are usually installed in the negative wire to prevent accidental shorts with grounded enclosures.
