Master Battery Disconnect Kit

from $40.00

This kit allows for manual disconnect of high current battery lines. Ideal for isolating battery banks by interrupting output circuits on your battery bank. For use when putting a system with DC charging input into medium-long term storage, or for O&M of the battery bank. This switch is typically used between a battery bank and a post or fuse that all the positive connections attach to.

We offer kits for systems with 2000VA or 3000VA inverters.

Please note, the 5000VA 12V inverters would need a more heavy-duty switch.
