3-5. DC Wiring Connections
Follow this procedure to connect the battery cables to the DC input terminals
of the Inverter. The cables should be as short as possible (less than 10 feet
/ 3 meters ideally) and large enough to handle the required current in
accordance with the electrical codes or regulations applicable to the
installation. Cables that are not an adequate gauge (too narrow) or too long
will deteriorate inverter performance such as poor surge capability and
frequent low-input voltage warnings and shutdowns.
These low input voltage warnings are due to DC voltage drop across the
cables from the inverter to the batteries. The longer and narrower the cables,
the greater the voltage drop.
Increasing DC cable size helps improve the situation. SAMLEX AMERICA
INC. recommends the following cables for optimum inverter performance.
