GLOSSARY

GFCI (Ground Fault Circuit Interrupter) A protective device that rapidly de-energizes a circuit when current to ground exceeds a predetermined value.

Ground The reference potential of a circuit. In automotive use, the result of attaching one battery cable to the body or frame which is used as a path for completing a circuit in lieu of a direct wire from a component. This method is not suitable for connecting the negative cable of the inverter to ground. Instead, route the cable directly to the negative terminal of the battery.

LED (Light Emitting Diode) Indicator light.

NEC National Electric Code

Negative Designating or pertaining to electrical potential. The negative terminal is the point from which electrons flow during discharge.

Ohm A unit for measuring electrical resistance.

Ohm’s Law Expresses the relationship between voltage (V) and current (I) in an electrical circuit with resistance (R). It can be expressed as follows: V=IR. If any two of the three values are known, the third value can be calculated by using the above formula.

Positive Designating or pertaining to electrical potential; opposite of negative. The positive battery terminal is the point where electrons return to the battery during discharge.

Power Sharing The feature of the charger to reduce its output when the AC power being consumed by the charger and external AC loads connected to the output of the inverter are in excess of the input breaker rating.

TSC Abbreviation for Temperature Sensitive Charging. The ability of the charger to adjust its charging voltage based on the temperature sensed at the battery bank if a temperature probe is used.

Volt The unit of measure for electric potential.

Watt The unit for measuring electrical power, i.e., the rate of doing work, in moving electrons by or against an electric potential.

Watt-Hour(Watt-HR, WH) The unit for measuring electrical energy which equals watts x hours.

Wet Cell Battery A type of battery that uses liquid as an electrolyte. The wet cell battery requires periodic maintenance: cleaning the connections, checking the electrolyte level and performing an equalization cycle.
