Prepaid metering

A prepaid metering system enables customers to pay money to the facility management in advance for a fixed energy value. Prepaid metering is advantageous to both, the facility management and customers. While the facility management can eliminate meter readings and get advanced payments, the customers can be freed of penalty through already stored energy consumption as against unit consumption.

The meter supports prepaid energy metering. Customers can add on energy credits to the balance register of the meter through communication only. The meter starts deducting the units based on energy consumption.

The customer can set a minimum value for energy credits consumption, beyond which the meter raises an alarm. The meter indicates the alarm through front panel LED, by blinking the top most LED on the load bar. In situations where the energy credits get exhausted, the meter switches on the relay. Beyond which, if the energy consumption continues, the meter keeps accumulating negative balance. When the customers recharge the next time, the negative accumulated energy will get deducted and only the balance energy will get credited for use.

The facility management can configure any one of the power source, that is Utility, Alternate Source, or Total (Utility + Alternate Source) based on the billing system.
