3-5. Making DC Wiring Connections
Follow this procedure to connect the battery cables to the DC input terminals
of the Inverter. Your cables should be as short as possible (ideally, less than
6 feet / 1.8 meters) enough to handle the required current in accordance with
the electrical codes or regulations application. Cables are not an adequate
gauge (too narrow) or too long will decrease the inverter performances such
as poor surge capability and low input voltage warnings frequently and
shutdowns. UVP warning presents due to DC voltage drop across the cables
from the inverter to the batteries.
The longer or narrower the cables, the greater the voltage drop.
Increasing your DC cable size will help improve the situation.
