Defined Terms

Blended Grid Power: Power supplied by a combination of on grid power and any combination of the off grid sources. The Smart Frogs patented blending module allows the unit to supply the most efficient source of power by blending multiple input sources.

ABS Plastic: Acrylonitrile Butadiene Styrene (ABS) is the polymerization of Acrylonitrile, Butadiene, and Styrene monomers. ABS plastic is an ideal material for structural applications when impact resistance, strength, and stiffness are required. The Smart Frog housing is made of high quality ABS plastic which will withstand the elements, and will not rust like many AC units.

Decibel rating: A decibel is a unit used to measure the relative intensity of sound.

Demand Response: When utility companies need to shed electricity load, they employ their demand response programs where they provide incentive payments to customers designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized. The Smart Frog allows you to take advantage of these programs without having to reduce the amount of electricity youre using, it will just switch the load to the standby generator and/or solar power if available.

Distributed Generation: DG or decentralized energy is generated or stored by a variety of small, grid-connected devices referred to as distributed energy resources (DER). Rather than generating power at large centralized power plants, and transporting it hundreds of miles to the end users, power is generated at the point of use.

Grid Tied Inverter: converts direct current (DC) electricity into alternating current (AC) with an ability to synchronize to interface with a utility line. Its applications are converting DC sources such as solar panels, small wind turbines or standby generators into AC for tying with the grid. This also allows you to sell any excess power generated from DC sources back to the grid to either credit your account, or pay you per kWh depending on the utility. Every PGC Smart Frog comes with a grid tied inverter inside the unit.

Kilowatt (kW): a unit to measure electrical power, 1 KW = 1,000 Watts.

Kilowatt Hour (kWh): a unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour (1 h) of time.

Load Shedding: Load shedding is used to help manage the amount of electricity used in a business, home or certain geographic location during peak demand times. Some utilities allow the customer to participate in load shedding or demand response programs, and will pay the customer to reduce the amount of electricity they are using. The Smart Frog allows you to take advantage of these programs without having to reduce the amount of electricity youre using, it will just switch the load to the standby generator and/or solar power if available.

Micro Power Generation: Similar to Distributed Generation, PGCs technology works as micro power plants, that can connect multiply devices on-grid and off grid, as well as blend the two generating power sources.

Off Grid Power: Power that is supplied by some other source than the normal utility system, such as a standby generator, solar system, battery pack, etc.

On Grid Power: Power that is supplied by the utility system through your regular retail electricity supplier (REP).

Plug and play solar: This means that to generate solar power the only item that is needed is a solar panel. The Smart Frog is already hooked up to the electrical system, and has a grid-tied inverter inside the unit requiring only a panel to start generating solar power.

Point of Use Generation: PGC has developed this type of generation that can use multiple sources of on-site power that PGC then generates into electricity to be used at the point-of-use. This eliminates any transmission energy lost, extra costs and uses the most efficient resource available.

Standby generation: Also known as backup generation, is a back-up electrical system that operates automatically within seconds of a utility outage. An automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load of the AC, house, business, etc., to the generator.

Transfer switch: A transfer switch is an electrical switch that switches a load between two sources. In terms of standby generation, once the utility grid goes out, the transfer switches the household load onto the generator.

HVAC Terms

AFUE: The Annual Fuel Utilization Efficiency (AFUE) is a measure of a gas furnace's efficiency in converting fuel to energy, by projecting the average thermal efficiency for a complete heating season. A higher AFUE rating means greater energy efficiency.

AHRI: Air Conditioning Heating and Refrigeration Institute is an industry trade association that develops standards for measuring and certifying product performance.

Air Handler: The indoor portion of an air conditioner or heat pump that moves cooled or heated air throughout the ductwork of your home. An air handler is usually a furnace or a blower coil. Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the air handler.

BTU: One British Thermal Unit (BTU) represents the amount of heat required to raise or lower the temperature of one pound of water one degree Fahrenheit. The heat extracted from your home by an air conditioner is measured in BTUs.

BTUh: The heat extracted from your home by an air conditioner is measured in BTUs, while cooling and heating capacities are referred to in British Thermal Units per hour. For reference, 12,000 BTUh equals one ton of cooling.

Condenser Coil: Also referred to as the outdoor coil, is the outdoor portion of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year.

EER: The Energy Efficiency Ratio (EER) of a cooling unit is determined by the output cooling divided by the electrical power input. As opposed to SEER, which is calculated over a range of outside temperatures, EER is typically determined by a set outside air temperature, a set inside air temperature and a 50% relative humidity.

Evaporative Coil: Often called the indoor coil, is the part of the air conditioner or heat pump that is located inside the air handler or attached to the furnace. Its primary function is to absorb the heat from the air in your house.

SEER: The Seasonal Energy Efficiency Ratio (SEER) measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame. A higher SEER rating means greater energy efficiency.

Ton: Unit of measurement for determining cooling capacity. One ton equals 12,000 BTUh.

Variable Speed Compressor: The PGC Smart Frog unit uses a variable speed compressor that slowly increases the RPM of your AC to keep a consistent temperature with the most efficient use of energy.
