MPP

The Maximum Power Point is the point on the current-voltage (I-V) curve of an array or string, where

the product of current and voltage has it’s maximum value.

NEC

The National Electrical Code (NEC), or NFPA 70, is a United States standard for the safe installation

of electrical wiring and equipment.

Power dissipation

Power dissipation is designated as the difference between absorbed power and power of a device

or process yielded. Power dissipation is released mainly as heat.

PV cell

PV cells are large-surface photodiodes which convert light energy (generally sunlight) into electrical

energy. This comes about by utilization of the photoelectric effect (photovoltaics).

PV array

System comprising of a number of PV modules.

PV module

Part of a PV generator; converts PV energy into electrical energy.

RJ-45

Abbreviation for standardized eight-pole electrical connector connection. RJ stands for Registered

Jack (standardized socket).

RS-485 (EIA485)

Differential voltage interface on which the genuine signal is transmitted on one core and the ne-

gated (or negative) signal on the other core.

Inverter

is an electrical device which converts DC direct voltage into AC voltage and/or direct current into

alternating current.

String

Designates a group of electrical PV modules ammended in series.

Stands for Underwriters Laboratory, an organization that sets standards for different product cat-

egories and tests products to make sure they meet the standards.
