Xantrex Technology 1500 manual Connecting to an External Battery, Extended Operating Time

Connecting to an External Battery

Extended Operating Time

Much longer battery operating time is possible when connecting XPower 1500 to an additional external battery. For example, an external 17 amp- hour battery will increase XPower 1500’s operating time by about 33%. Since XPower 1500 uses three 17 amp-hour batteries, we recommend connecting one or more 17 amp-hour batteries externally when you want to increase operating time.

WARNING: Explosion hazard

Use a sealed, non-spillable battery for indoor use. Common auto and marine batteries are not suitable for indoor use unless their fumes are vented outdoors.

WARNING: Chemical hazard

Battery acid is corrosive. Wear eye protection and protective clothing when working with batteries.

Preparing the Cables

To connect an external battery to XPower 1500 you will need two pieces of #2 AWG cable with appropriate connectors fastened to each end. Keep the length of each cable as short as possible, and when using #2 AWG cable, the length of each piece should not exceed 5 feet. One cable will be used to connect the positive (+) terminal of the external battery to XPower 1500’s positive High Power DC Terminal (red cover), and the other cable will be used to connect the negative (-) terminal of the external battery to XPower 1500’s negative High Power DC Terminal (black cover).

Remove ½” of insulation from the end of each cable. On one end of each cable attach a 5/16” ring terminal. On the opposite end of each cable attach a permanent type connector that is designed for connecting to the terminals of your external battery. Make sure all terminals are securely connected to the cable ends and check them any time the cables are used to connect the external battery to XPower 1500.
