Question 1

What makes a dual source meter different from a single source meter?

Accepted Answer

A dual source meter tracks two power sources — mains grid and DG/inverter — independently. It records separate kWh for each source so the billing system can apply the correct tariff: lower grid rate and higher DG rate, fairly charged per resident.

Question 2

Who invented dual source metering in India?

Accepted Answer

PES Electrical pioneered dual source metering in India. The technology solves the long-standing problem of fairly billing DG electricity in housing societies where DG running costs (Rs. 8-12/unit) are significantly higher than grid tariff (Rs. 4-6/unit).

Question 3

Can societies charge different tariffs for grid and DG electricity?

Accepted Answer

Yes. The PES-12-DS records grid kWh and DG kWh in separate registers. The AMC billing system applies the configured rate for each source and generates a single combined bill for the resident — no manual calculation needed.

Question 4

Does the PES-12-DS switch sources automatically?

Accepted Answer

Yes. On mains failure the meter detects the changeover and begins recording on the DG register automatically. On mains restoration it switches back. No manual intervention or reconfiguration is required.

Question 5

Is the PES-12-DS useful if DG runs only a few hours a day?

Accepted Answer

Absolutely. Even 1-2 hours of daily DG operation adds up significantly over a month. The dual source meter ensures those units are billed at the correct DG tariff, recovering the actual generator running cost fairly from each resident.
