to the inverter, resulting in lower efficiency and peak output voltage. A lower surge power (needed to start motor-operated loads) is also experienced. Undersized cables are consequently of no use as they reduce the efficiency achieved thus far.

• Have short cable runs where possible.
• Shorten the battery and inverter distance with a little rearrangement of your electrical panel.
• A lower DC system voltage will enable a shorter cable run.
• Longer runs require oversized cables or a higher system voltage.

Large cables are more costly but they can be a good investment for better system performance. Xantrex Technology recommends taping positive and negative wires to the inverter for a parallel set of leads to achieve lower wire inductance and better inverter performance.
