3-3 DC Wiring Connections
Follow the instructions to connect the battery cables to DC input terminals of
the Inverter. The cable should be as short as possible (less than 6 feet / 1.8
meters ideally) so that it can handle the required current in accordance with
the electrical codes or regulations application. Inappropriate length of cables
will deteriorate the inverter performance such as poor surge capability,
frequent low-input voltage warnings, and shutdown. UVP warning occurs
when DC voltage drops across the cables from the inverter to the batteries.
The longer or narrower the cables, the more the voltage drop.
Increasing your DC cable size will help improve the situation.
The following recommended cables are for the best performance of the
inverter. (Apply both 120V and 230V versions)
