## Questions & Answers

**Q: In case of grid power outage, will this unit keep using the inverter power even if the battery goes below the low voltage cut-off?**
A: If there is no grid power available, and the batteries fall below your low voltage battery cut-off...your inverter will shut down.

**Q: My invertor is 1000 watts can the spartan 4500 w gave a output  more than the invertor 1000 watts**
A: Spartan is a 4500 watt that takes in input the 1000 watt inverter is 1000 watt output is not going to increase your inverter power

**Q: i would like to use this to run a grid tie inverter once my battery are topped off**
A: That is pretty sparse information about your setup but the purpose of this device is to use an inverter/use batteries at voltages you set or otherwise it uses grid power.   Or phrased another way, it uses inverter/batteries until the voltage drops to voltages that you set and then it switches to grid power to save your batteries.  This answer is for the TS4500PLUS model.

**Q: the Battery Plug is it a special one ? it looks like in the pictures**
A: No, not special. It only has to house small cable (10 AWG for example) as it is only used to read battery voltage.  Your thick battery cables would be going from the inverter to the battery(ies)
