  1. Amp-Hour Meters Kali Shaw

  2. What is it? • Indicates system’s condition • Counts amp-hours used when using power • Counts backwards to zero • Zero means battery is fully charged • Nickel-cadmium / nickel-iron batteries • Hard to tell state of charge from voltage • Sulfation caused by undercharging is main destroyer of lead-acid batteries *Note: Amp hour meters lose accuracy if batteries are always run in a very discharged state.

  3. Tri-Metric 2020 Battery Monitor Amp-Hour Meter–Creative Energy Technologies • 12 or 24 volt battery systems (48 w/ adapter) • Lit when charging, flashes when charged • Volts, Amps, Amp-Hours Amp-Hours in numbers or as % full • Records min/max voltage,days since charged and equalized, total lifetime amp-hours withdrawn

  4. Shunts • Required for operation • Based on inverter type and watts • Relatively inexpensive
