Software Specification:
Pre-Paid Application Power Scan Software (Pre-Paid Application) Tariff application details: The pre paid energy metering system with the software shall be used to implement following types of tariff Application: i) Flat rate of energy ii) Common area energy charges Flat rate / per sq fit iii) Energy / VAT tax on fixed percentage basis iv) Standing charges (like fixed KW charges & monthly maintenance charges) v) The energy meter shall not disconnect supply in defined hours of the day. For example if evening 10 pm to morning 8 am is defined as happy hours then the meter shall not disconnect during this time period even when the energy meter runs out of credit. vi) The supply shall not be terminated on specified days, for example if Sunday is defined as a holiday then the switch will remain on Sunday even if the pre payment energy meter runs out of credit. The Software Measures electricity consumption and decrements the credit based on the cost per unit of electricity. Display Unit A remote display which when connected to the meter allows all features to be conveniently accessed from any room in the house. Both these shall be connected with the help of RG-11 cable. Features of the pre paid metering software shall be as follows: 1. Option to define Tariff Headings under ledgers - Main Supply, DG Backup, Other Charges and Interest & Late Payments. One can have as many heading as intended. 2. Option to define Taxes on Each Tariff Heading. 3. Option to capture dual energy - Mains & DG and Over Demand of Main & DG. 4. Option to Recharge by Cash/Cheque/Credit/Debit Card & online payment using Credit/Debit/net banking (Optional). 5. Option to view meter reading online from any location by web (optional). 14
