Efunity becomes PQSynergyTM & PQ Blog Gold Sponsor
We are pleased to announce that Efunity was a Golden Sponsor for PQSynergyTM Conference Exhibition 2022 and Power Quality Blog (PQ Blog). It is a privilege to be supported by Efunity.
We are grateful to Eddie Ong, Chief Operating Officer and to the Efunity team.
Efunity is a company based out of Singapore that offers turnkey solutions in energy and power quality monitoring and analysis. We also carry and keep stock for a wide range of smart power meters, branch feeder meters, power quality analyzers, current sensors and intelligent earth leakage relays.
Recently appointed as distributor of PQAi, an IOT-capable power quality analyzer that can monitor up to 15 three-phase channels, we are able to expand our reach to new industries and applications where power quality monitoring is often sidestepped due to a lack of cost-effective solutions.
We are currently working with utilities and asset owners in implementing smart grid solutions to improve the overall operational status of the grid network to better match supply and demand. As the world transition towards widespread adoption of sustainable energy and electric vehicles, we are preparing customers for the challenges that these technologies may bring. This is particular important for industries that require “zero incident, zero downtime”.
Anchored by our vast experience and supported by our strong R&D team, we are able to help you resolve existing issues and mitigate future problems in your infrastructure. Energy and power is our business. Let’s start a conversation.

PQView 4 is available in three (3) editions: PQView Express, PQView Standard, and PQView Professional.
PQView 4 Express
PQView Express is intended for single-server installation. The installation of Express is a very simple process: it only requires running two installers (and upgrades only require one installer). PQView Express is recommended for small organizations, or for customers who wish to try out PQView in a simplified form. PQView Express does not use Microsoft IIS. The maximum number of monitors that can be integrated with PQView Express is 50.
PQView 4 Standard
PQView Standard is the next step up from Express. Standard includes all the features of Express, plus it supports distributed installations and uses Microsoft IIS. PQView Standard is recommended for system sizes larger than 50 monitors and/or organizations with infrastructures that require distributed installations.
PQView 4 Professional
PQView Professional includes all of the features of the Standard version and adds support for Windows Authentication, additional database support (MS Access and SQL Azure), and includes additional advanced analysis options unavailable in the Standard version.
