BIS Certification Solar Inverter

1. ● BIS Certification for solar inverters is mandatory for manufacturers and importers targeting the Indian market. ● Without this compliance, shipments can be seized or rejected at customs. ●Here’s how to obtain BIS approval under IS 16221 efficiently and legally. Introduction Earlier this year, a solar EPC firm in Hyderabad imported a shipment of hybrid inverters from a Chinese manufacturer. Their engineers loved the tech—clean build, great efficiency—but within three days of landing at Nhava Sheva Port, customs flagged the consignment. No BIS registration. No clearance. The firm scrambled, paid heavy demurrage fees, and lost ₹12+ lakh in a month. Worse, they lost their first major tender because they couldn’t deliver on time. That’s the cost of ignoring BIS certification. If you’re in the solar business—manufacturer, importer, or EPC integrator—BIS Certification for solar invertersisn’t just another paperwork chore. It’s your ticket to play in the Indian market, especially in 2025 when enforcement is stricter than ever. What Is BIS Certification for Solar Inverters? Bureau of Indian Standards (BIS) is the designated national headquarters for India that ensures quality and safety standards for various industries. BIS certification for solar inverters falls under a Compulsory Registration Scheme. ●IS 16221 Part 1: General Requirements ●IS 16221 Part 2: Safety Requirements If your inverter—grid-tied, hybrid, or off-grid—is being sold or distributed in India, it must comply with these standards and be tested at a BIS-recognized lab. Why Is BIS Certification Mandatory for Solar Inverters?

2. The solar sector in India is growing at record pace, with both residential rooftops and industrial projects booming. But with growth comes responsibility. Why BIS Is Crucial: ● Protects users from short circuits, fire hazards, or grid instability ● Prevents low-grade imports that fail Indian weather or grid conditions ● Ensures interoperability with DISCOMs and Indian metering norms ● Complies with MNRE and BIS circulars to be eligible for tenders and subsidies Imagine selling a non-certified inverter to a customer. One power surge, and the blame lands on you—even if the fault was in the build. That’s exactly why the Ministry of New and Renewable Energy (MNRE) and BIS enforce this standard. Types of Inverters That Must Be BIS Certified If your product fits in any of the following categories, BIS certification is mandatory: Inverter Type Requires BIS? Standard Code Grid-Tied Inverter Yes IS 16221 (Part 1 & 2) Hybrid Inverter Yes IS 16221 (Part 1 & 2) Off-Grid Inverter Yes IS 16221 (Part 1 & 2) Micro/String Inverter Yes IS 16221 (Part 1 & 2) Important: Even if your inverter is branded abroad, once you bring it into India—it must comply. How BIS Certification Works – Process Step by Step (2025 Update)

3. BIS certification sounds complex, but with the right approach, it’s a predictable and achievable process. Here's how it works in 2025: Step 1: Product Testing in BIS Lab ● Your inverter is sent to a BIS-recognized lab in India ● Testing is done as per IS 16221-1 and 16221-2 ● Tests include insulation resistance, overvoltage, EMC, surge protection, etc. Step 2: File Online Application via Manakonline ● Upload lab reports, product datasheet, brand details, etc. ● Application is submitted by the manufacturer or their Indian representative Step 3: Factory Audit (Only for Foreign Brands) ● BIS officials may inspect the overseas plant to verify quality control systems ● Indian brands usually skip this step Step 4: Get the CRS Certificate ● Valid for 2 years and renewable ● Certificate includes your model number, brand name, and manufacturing unit address Quote Summary: “From inverter testing to CRS approval, the process typically takes 6–8 weeks if documents are ready.” Required Documents for BIS Solar Inverter Approval Here’s what you'll need to prepare before filing your application: ● BIS-approved test report (not older than 90 days)

4. ● Product manual and technical sheet ● Manufacturing license or MSME certificate ● Brand ownership proof or trademark ● ISO certificate (ISO 9001 recommended) ● Indian Authorized Representative (IAR) letter ● BIS marking artwork and labelling sample For foreign entities, appointing an Indian representative is non-negotiable under BIS rules. Timelines & Costs for BIS Certification – Realistic Estimates Component Time Required Estimated Cost (₹) Lab Testing 2–3 weeks ₹50,000 –₹1,00,000 Application & Review 1–2 weeks ₹15,000 –₹30,000 Factory Audit (if needed) 2 weeks (avg.) ₹1,00,000 – ₹2,00,000 Final Approval 5–10 working days ₹20,000 –₹45,000 Total time: 6–8 weeks Total cost (approx): ₹85,000 –₹2.5 lakh, depending on your brand location and application complexity. Real Brand Case: How Huawei Avoided Port Blockage Huawei Solar India ensured BIS certification was completed even before their new inverter line was shipped to India. By using a trusted local consultant, they got test reports in advance and submitted BIS applications proactively.

5. Result? 0 delays at port 100% clearance within 24 hours Immediate market availability in India This is what Indian EPCs and foreign brands should learn—compliance is cheaper than delay. Common Mistakes to Avoid (Many Brands Still Make These) Even experienced importers make avoidable mistakes that cost them money and credibility. ● Submitting expired test reports ● Mismatch in model number and test certificate ● Ignoring labelling standards (missing CRS logo) ● Submitting scanned, unclear documents ● Not keeping an Indian IAR in the loop during renewal Why Your Business Needs BIS Certification (Beyond Compliance) Let’s be honest: No BIS means no entry. But beyond just legality, here’s why BIS is also a growth strategy: EPC Tender Eligibility–Govt and DISCOMs won’t touch non-BIS inverters Customer Confidence– BIS mark on packaging boosts trust Faster Imports– No hold-up at customs Reduced Risk– Ensures product will handle Indian voltage swings and grid fluctuations You may sell one inverter today, but for repeat business and long-term scale—you need the BIS tag.

6.
