Most Indian solar inverter brands manufacture up to 10 kW or 15 kW and import anything larger. That creates a service gap for commercial buyers who need 20 kW, 50 kW, or 100 kW hybrid inverters but cannot get them from a manufacturer with an Indian service network. This guide explains what to look for in a hybrid solar inverter manufacturer covering the full range from 2 kW to 100 kW.
1. What Capacity Range Can Be Manufactured in India?
Nexus Solar Energy manufactures hybrid solar inverters from 2 kW to 100 kW in-house at Chola Industrial Area, Bulandshahr, Uttar Pradesh.
| Segment | Capacity | Typical Use |
|---|---|---|
| Residential | 2-10 kW | Homes, small shops |
| Large home / small commercial | 10-15 kW | Large homes, offices, small factories |
| Commercial | 16-100 kW | Factories, commercial buildings, institutional |
The 16-100 kW models are built to order. For pricing and specifications on commercial sizes, contact the manufacturer directly rather than expecting off-the-shelf availability.
Most Indian brands stop at residential sizes and import anything larger. When the inverter is imported, board-level repair is rarely available in India — a failed unit means shipping it back to the original factory or replacing it entirely.
2. Which Models Carry a BIS Licence?
BIS certification for solar inverters covers two standards: IS 16221 (Part 2):2015 for the inverter itself, and IS 16169:2014 for anti-islanding — the safety test that ensures the inverter disconnects from the grid during a power outage, preventing energy from feeding back into a live grid line.
Nexus Solar Energy holds BIS licence R-93035050 under these standards. However, BIS coverage applies to specific models, not to the entire range:
| BIS-Covered Models | NOT BIS-Covered |
|---|---|
| DEV HYD 2 kW, 3 kW, 4 kW, 5 kW, 6 kW, 7.5 kW, 8 kW, 10 kW, 12 kW | Plain 3 kW IP21, 3.5 kW Advance, plain 6 kW non-IP65, 11 kW, 15 kW 3-Phase, 1 kVA 12V PCU |
A manufacturer that says 'all our products are BIS certified' is not being precise. BIS certification applies to specific models tested under specific licence numbers.
3. Can It Run Without a Battery?
Yes. Devsol hybrid inverters support battery-less operation — they function on-grid style without a battery bank connected. This reduces upfront cost and maintenance. The inverter draws from solar panels and the grid directly, powering loads in real time.
When a battery is added later, the same inverter charges and manages it without requiring a separate charge controller. This is a key difference between a hybrid inverter and a standard off-grid inverter.
4. What Are the Engineering Features?
- Dual MPPT — two independent Maximum Power Point Trackers, allowing two separate solar panel arrays to operate at different orientations or tilt angles.
- MPPT charge controllers — available in 100A and 160A configurations for high-current battery charging.
- Parallel capability — 6, 8, 10, and 12 kW models can be paralleled for higher capacity, configurable as single phase or three phase.
- Generator sync — accepts input from a diesel generator for hybrid backup.
- Remote operation — monitor and control the inverter remotely.
- Touch screen interface — local display for configuration and monitoring.
- Battery chemistry support — lead-acid, tubular, lithium, and sodium batteries.
5. What Does the IP Rating Mean for Warranty and Installation?
IP (Ingress Protection) rating determines where the inverter can be installed and how long the warranty lasts:
| IP Rating | Protection Level | Installation | Warranty |
|---|---|---|---|
| IP21 | Basic — protected from objects and vertically falling water | Indoor only | 2 years |
| IP54 | Dust protected and splash-proof | Sheltered outdoor | 4 years |
| IP65 | Dust-tight and protected from water jets | Full outdoor | 5 years |
| IP66 | Dust-tight and protected from powerful water jets | Full outdoor, harsh conditions | 5 years |
Models by IP rating:
- IP65: Devsol 6 kW Pro 9G
- IP66: 15 kW 3-Phase, 12 kW
- IP54: 5 kW 24V, 3.5 kW 24V, 3 kW INNO 9G
- IP21: 1 kW, 2 kW, 8 kW, 10 kW, 11 kW, entire INNO 8G series
6. Can It Be Repaired in India?
All Devsol hybrid inverters are made in India and repairable in India. This matters because an imported inverter that cannot be board-level repaired locally has a shorter effective service life. When a component fails on an imported unit, the entire inverter may need to be shipped overseas or replaced — at significant cost and downtime.
Devsol has 1,150+ dealers and distributors across India, providing local service access. See Best Hybrid Solar Inverter in India for model-by-model selection guidance.
Frequently Asked Questions
Who manufactures hybrid solar inverters in India?
Nexus Solar Energy manufactures hybrid solar inverters from 2 kW to 100 kW in-house at their facility in Bulandshahr, Uttar Pradesh. The inverters are sold under the Devsol brand and carry BIS licence R-93035050 for eligible models.
Can I get a 50 kW or 100 kW hybrid inverter in India?
Yes. Nexus Solar Energy manufactures hybrid inverters up to 100 kW in-house. These are built to order for commercial applications. Contact the manufacturer for specifications and pricing on commercial sizes.
What does IS 16221 certification mean?
IS 16221 (Part 2):2015 is the Indian standard for solar inverters, covering electrical safety, performance and grid compatibility. IS 16169:2014 is the companion standard for anti-islanding safety — ensuring the inverter disconnects from the grid during outages. BIS licence R-93035050 covers specific models under both standards.
Can a hybrid inverter run without a battery?
Yes. Devsol hybrid inverters support battery-less operation, functioning on-grid style with no battery bank. Solar energy powers loads directly in real time. A battery can be added later without changing the inverter.
What IP rating do I need for outdoor installation?
For full outdoor installation, use IP65 or IP66 rated inverters. IP54 is suitable for sheltered outdoor locations. IP21 inverters must be installed indoors only. Higher IP ratings also come with longer warranty periods (5 years for IP65/IP66 vs 2 years for IP21).
Is the inverter repairable in India?
Yes. All Devsol hybrid inverters are manufactured and repairable in India. Service is available through 1,150+ dealers and distributors across India, avoiding the cost and downtime of shipping units overseas.
