Overview of Solar Inverter & Charge Controller Testing

Tested by: BIS-recognised partner lab
Regulation: IS 16221, IS 16169
Typical turnaround: 4–6 weeks
Sample needed: 2–3 units per model

Inverters for solar systems fall under the same BIS registration requirement as modules. Safety is tested to IS 16221 (Parts 1 and 2, adopted from IEC 62109), and grid-tied inverters must pass the anti-islanding test of IS 16169, which checks that the inverter disconnects when the grid fails so that line workers are not put at risk.

DISCOMs and rooftop solar schemes also look at conversion efficiency, power quality (harmonics, power factor) and grid-support functions. Off-grid and hybrid systems are tested with their batteries and charge controllers. Storage batteries for solar systems have their own standard, IS 16270.

How we handle Solar Inverter & Charge Controller Testing

1
Assessment of requirement
We confirm the standard, the list of tests and how many samples your product needs.
2
Sample collection
We collect the samples from your factory or warehouse, or tell you exactly where to send them.
3
Right lab assigned
We choose an accredited lab (NABL, BIS-recognised or ILAC) that covers your standard and can start soonest.
4
Testing
The lab tests your samples against the standard. We follow up and tell you at once if a test fails.
5
Test report
You receive the signed test report, ready to use for BIS, WPC, CE or your buyer.

What the lab tests

Parameter	Why it is checked
Electrical safety (IS 16221)	Shock, energy and fire hazards
Anti-islanding (IS 16169)	Disconnection when the grid fails
Conversion efficiency	Weighted and peak efficiency
Power quality	Harmonics, DC injection, power factor
Environmental endurance	Temperature and humidity
EMC	Emission and immunity

The final list depends on your product, its standard and the purpose of testing. We confirm it with you before the sample goes to the lab.

Frequently asked questions

Is one test enough for a range of inverter ratings?

BIS allows ratings in a series to be grouped where the design is the same, with representative models tested. We confirm the grouping before testing to avoid repeating work.

Will BIS accept the report?

For BIS registration and licences, testing is done at a lab recognised by BIS for that standard, and BIS accepts reports only from such labs. For tenders and buyers, a NABL-accredited lab report is usually enough. We confirm which applies before booking.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
