+ | Only present on controllers with LOAD outputs. | ||
- | + | * **Low voltage disconnect (Vlvd)** - voltage at which the controller turns off loads to prevent excessive battery discharge. | |
- | + | * **Low voltage reconnect (Vlvr)** - the setpoint at which the load is turned back on after recovering from Vlvd cutoff. | |
