Low Voltage Shutdown Relay for Batteries
The low voltage shutdown relay will automatically disconnect the DC power between the batteries and inverter. When the relay disconnects, the inverter will shut down and prevent further draw on the battery or batteries. Once your batteries recharge to a safer level, the LVS will restore DC power to the inverter's DC inputs. The LVS will prevent deep discharges of your battery bank that shorten the life of your batteries.
The LVS is available for 12, 24, and 48 volt systems and comes pre-programmed for battery voltage.
Keep in mind that some power inverters need to be manually reset i.e. flipping the power switch back on if power is removed from the DC input. There are too many inverters to test in house, so we suggest you follow the next step to determine if your inverter requires a manual reset. To test your inverter before purchasing the Low Voltage Shutdown, disconnect your DC to AC power inverter on the DC side and let it sit for 5 minutes. Reconnect the DC power source. If you have to manually reset the inverter, this will also be the case when using the LVS.
