Background

4

BEE with the support from CLASP initiated Labeling Program forInverter, UPS, voltage stabilizers and Inverter Batteries in October2010.

PwC worked as an implementing partner for this project to BEE and

CLASP.

The technical analysis of all the products has been completed andpresently BEE is finalizing energy performance requirements forthese products.

Rationale for the Project

5

Peak shortage of Power in the country stood at 10.1% as per 2009-2010 data(CEA).

Back up power system market is growing at the rapid rate and at present itsthe need of every house hold especially in cities.

Inverter/Inverter batteries market comprised of organized as well as un

organized players. No information about performance of products and limited awareness

amongst consumers.

In case of voltage stabilizers, it was important to address this product as thisis associated with market of Air conditioners.

Considering growing need of UPS in different operations, program up to 5KVA was initiated to address market/technical issues so as to move tohigher categories in future.

Technology Assessment Inverters

There are three types of Inverter terminology in

place Square Wave Inverters

Quasi/Modified square Wave Inverters

Sine Wave Inverters

Inverters85%

Sine WaveInverters

15%

Market Share of different types ofInverter

As per initial market data, the total harmonic distortion in the square waveformInverters is more as compared to sine wave Inverters, but the market of square waveinverters is much higher. Why ?

The inverters are rated in terms of VA. How much output watt is actually available ?

What is difference in efficiency of different inverter technologies and its performanceagainst minimum requirements set by BIS ?

Do we follow our applicable IS for inverters ?

Draft national test standard for UPS is Doc: ET 31(6128)

International reference test standard for testing of UPS is IEC62040-3& EC directive (Code of Conduct)

The UPS are operated in Normal and By pass mode.

This program captured performance of UPS in Normal mode.

Online UPS can provide the better conditioning and can protect the equipments fromadverse voltage conditions and thus used for sensitive applications

Technology Assessment Inverter Batteries

The batteries that are used for the domestic

purpose are of 12 V and they are of three types

Lead Acid flat plate battery

IS 13369:1992 is the applicable test standard for Inverter Batteries in India

There is no specific terminology for Inverter batteries in standards.

Depth of discharge & backup provided by tubular battery is more than simple leadacid.

The program was restricted to tubular and flat plate batteries.

Capacity and Efficiency ( Watt hour ) are considered two important parameters toassess the performance.

Testing of product is very important and critical phase for the whole labeling

program as

It helps to have a clear cut idea about the actual performance parameters of theproduct that is being sold in the market before setting labeling thresholds.

It helps in actual testing of standards addressing practical implementationissues which helps to design M&E plan

Key challenges faced during the program

Availability of true market/technical data at the start of the program

Capturing true market/performance behavior especially for products havingunorganized players.

Gap analysis of test standards as some of the standards are too old or needsrevision on certain parameters

True sample size for testing

Absence of the International benchmarking criteria for some of the products

Defining test labs requirements for different products

Lessons Learnt

Test standards are useful guide but also requires detailed review andrevisions to strengthen the process.

Testing is a key component for designing Standard & Labeling program . Ithelps to know the preparedness of the market to move to implementationphase. The success of MV&E phase largely depends on testing approachduring preparatory phase.

The set approach changes during the complete Preparatory phase. ( e.g.batteries )

Testing is not about what is happening, but it is about why it is happening ?

Role of labs is not about usual testing, but a more active engagement and

their experience. Invest time at preparatory stage rather than facing unseen problems at

Implementation stage.
