Can the Spirit 2 battery be charged with solar panels?

Yes, the Spirit 2 battery (Spirit Battery Ultra) can be charged using solar panels, making it ideal for extended sailing or cruising. You will need the Spirit 2 Solar Charge Controller, which manages the charging process safely.

Compatible solar panels must meet the following specifications:

• Output: 100W to 180W
• Operating voltage: 12V to 35V
• Maximum current: 10A
• Connectors: MC4

Many third-party solar panels that meet these specs are compatible. Solar charging can be done while the motor is in use or while it is off. You can also charge the Spirit 2 battery simultaneously with a solar panel connected and the battery installed on the motor, making it a set-and-forget solution for boats with permanent solar installations.
