Each UPS module may have its own battery cabinet(s), or may share the same battery cabinet(s) with the other UPS module. NOTE: The installation procedures of this manual only refer to the parallel cabinet and its connection to the UPS cabinets for parallel redundant operation.
Connect your battery to the inverter, charge controller, and charging source. Next, connect your home battery backup system to your home’s existing wiring using a transfer switch (or power input, if available). Once everything is hooked up, your home electrical system should draw from the backup battery the next time a power outage occurs.
(Partial Load) In this methods of wiring, the battery and UPS has been connected directly to the main supply where the output of the UPS has been connected to the partial load (specific appliances where we need continues power supply in case of power failure) with the help of two pole single phase manual changeover switch.
Refer to the Powerware 9315 Installation manual provided with the UPS system for input feeds to the UPS module. Each UPS module must be wired to its corresponding module output breaker in the cabinet with power cables sufficient for carrying the load. Recommended wiring size is listed in Tables A---3 and A---4 of Appendix A of this manual.
If possible, select batteries that reach at least double the storage capacity you need so that you can keep them from discharging below 50% capacity. Depending on the battery chemistry, “deep discharging” can negatively impact lifespan and performance. Below are some examples of plug-and-play portable power station battery backup options:
Load can be connected to the SP MCBs through switches. In case of power failuer, the UPS will automatically supply the backup power of the batteries to the connected appliances. In case when utility power restores, the UPS will start to charge the battery as well as supply the main power to the whole load connected through main distribution board.
