Installation Charge Rs.200/- ?????? Are you joking?

As this inverter setup is for only one room, we advise to place the inverter and battery in any small table or stand, right below the switch board. This idea eliminates the extra wire cost during installation. Total cost of wire will be under just 50 Rupees.

Ask the electrician to connect the fan and light switches to UPS line (also one plug point for mobile charging)
