Control Function Glossary

Low Volts Disconnect

Low Voltage Disconnect disconnects the batteries (Battery Disconnect) or the load (Load Disconnect), at the preset LVD disconnect voltage. This prevents damage to the batteries due to excessive deep discharge. The LVD reconnects the batteries or loads after the AC power is restored.

When configuring the LVD reconnect voltage, ensure that the expected open-circuit recovery voltage of the discharged batteries does not rise above the LVD reconnect voltage.

Temperature Compensation

Temperature Compensation automatically varies the float voltage to cancel the effects of increasing or decreasing ambient battery temperature.

As the ambient temperature of the batteries increases, the voltage required to maintain it in a fully charged state decreases.

Enable Temperature Compensation to help maintain optimum battery capacity over a wider temperature range, which in turn extends battery life.
