Protecting the Batteries

Batteries must be protected from excessive discharge in normal use, and circuit protection is required in the case of faults. The WattWorks DC Power Station provides circuit breakers as required by NEC code, and includes Low Voltage Disconnects (LVD) on all LED lighting circuits.

LVD (Low Voltage Disconnects) are used to remove DC loads at a pre-set DC Bus voltage that represents a low state of charge and will prevent damage to the battery pack from over-discharge. Battery cycle life is reduced and batteries can be permanently damaged by excessive over-discharge.

The AGM Type sealed lead acid batteries provided are generally maintenance free and do not require water. They are very reliable and will last for 5 years or more if deep discharge cycles are avoided as much as possible.
