Installation Guide

Each charge controller must be connected to its own PV array. Up to three PV array
strings can be connected in parallel to a single charge controller. See Connecting Multiple
PV Array Strings to One Unit on page 37.
WARNING
HAZARD OF ELECTRIC SHOCK AND FIRE
n The PV array voltage must never exceed 600 V in any condition (open circuit, cold
temperature, bright sun, etc.).
n The PV array current must never exceed 35 A for Conext MPPT 80 600, or 44 A for
Conext MPPT 100 600 in any condition (short circuit, hot temperature, bright sun, etc.).
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
Mounting
The instructions in this chapter are applicable to a typical stand-alone installation.
Installation procedures will vary according to your specific application. For special
applications, consult a qualified Renewable Energy System Installer or a Certified
Dealer.
Choosing a Location
WARNING
HAZARD OF ELECTRIC SHOCK, BURN, FIRE, AND EXPLOSION
The charge controller must be mounted vertically and installed indoors in a dry, protected
location away from flammable materials, sources of high temperature, moisture, and
vibration. The location must also be sheltered from direct sunlight, dust, and wind-blown
debris.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
Flammable or combustible materials are defined as “any material containing wood,
compressed paper, cellulose, plant fibers, plastics, liquids, or other material that will
ignite and burn, whether flame-proofed or not” according to the NFPA. Flammable liquids
are defined as “any liquid whose flash point does not exceed 100 °F (38 °C).” Examples
of flammable liquids are gasoline, methanol, and ether.
When choosing a wall to install the charge controller, choose a wall that is not considered
a flammable material such as concrete, brick, or metal.
