Question 1

What makes the three phase dual source meter unique?

Accepted Answer

The PES-20-DU combines three-phase measurement with dual-source tracking — recording grid and DG energy separately across all three phases. It is the only certified three-phase dual source smart meter manufactured in India, pioneered by PES Electrical.

Question 2

Which sectors benefit most from the PES-20-DU?

Accepted Answer

Large housing societies with three-phase common area DG supply, luxury high-rise residences, commercial complexes, IT parks, hospitals, and factories that run their own DG sets — any installation where three-phase DG and grid costs must be separately accounted for.

Question 3

How does the PES-20-DU handle unbalanced three-phase loads?

Accepted Answer

The meter measures all three phases independently and calculates total energy as the sum of per-phase measurements, ensuring accurate billing even when loads are unbalanced across phases — a common condition in residential common areas.

Question 4

What connectivity options does the PES-20-DU support?

Accepted Answer

RS-485 for wired building networks, GPRS for remote sites, and NB-IoT for low-power wide-area deployments — all feeding data into the PES centralised AMC dashboard for real-time monitoring and billing.
