Section 4: Inverter/Charger Installation
For best performance, the wire sizes shown in the table below will allow the Prosine to operate properly. Please note that regulatory requirements may not allow you to use the wire size given for 5 foot and 10 foot distances. Also, increasing the wire size will provide longer inverter performance.

Battery Cable Routing
When a distance separates positive and negative battery cables, they have much more inductance than if they are close together, and when the high current drawn by the inverter is flowing, strong magnetic fields are generated. These fields may interfere with sensitive equipment, so it is very important to route the positive and negative cables in parallel, as close together as possible.
