Hitachi Solar Inverters | Authorized Distributor

1. Is Hitachi Solar an Indian or Japanese brand?

Hitachi Hi-Rel Power Electronics is a 100% subsidiary of Hitachi Ltd, Japan. The inverters feature Japanese technology and R&D but are manufactured in their state-of-the-art facility in Sanand, Gujarat (India). This gives you the best of both worlds: Japanese quality with "Made in India" subsidy compliance.

2. Which Hitachi inverter is best for 1 MW PM KUSUM (Component A) projects?

For 1 MW - 2 MW ground-mounted projects, we recommend the Hitachi Si-350HV (350kW) 1500V String Inverter. Using 3 units of 350kW is superior to a single central inverter because if one unit fails, the other 66% of your plant keeps generating revenue. Loop Solar supplies these in bulk for KUSUM developers.

3. Can I use Hitachi inverters for PM KUSUM Component C (Grid Pumps)?

Yes. For solarizing existing agricultural pumps, the Hitachi Si-N Series (5kW - 20kW) is ideal. These 3-phase inverters synchronize with the rural grid to export excess power. Their robust design handles the voltage fluctuations typical of rural feeders better than standard residential inverters.

4. What is the complete range of Hitachi inverters available at Loop Solar?

Residential (1-Ph): 1.1kW | 2.2kW | 3.3kW | 5kW | 6kW
Residential/Small C&I (3-Ph): 5.5kW | 6.6kW | 8.8kW | 11kW | 15kW | 20kW | 25kW
Commercial (3-Ph Low Voltage): 30kW | 33kW | 40kW | 50kW | 60kW | 70kW | 80kW
Industrial (3-Ph High Capacity): 100kW | 110kW | 125kW | 250kW (1500V)

5. Why should I choose the 1500V (350kW) model over 1000V models?

1500V systems allow for longer string lengths (more panels in a series). This reduces the amount of DC cable, combiner boxes, and trenching work required, lowering your overall Balance of System (BOS) cost by up to 5-8%. It is the standard for modern KUSUM projects.

6. Are Hitachi inverters compatible with Adani Bifacial panels?

Yes. The new Si-N and Si-HV series support high DC input currents (up to 20A per string), making them fully compatible with large-format 550Wp - 700Wp Bifacial modules. Older inverter models often clip power with these new panels, but Hitachi's 2025 range does not.

7. How much DC overloading does Hitachi support?

Hitachi inverters support a DC/AC ratio of up to 1.5 (150%). This means for a 100kW inverter, you can install up to 150kW of solar panels. This ensures the inverter runs at full capacity for more hours in the day, significantly boosting total generation.

8. Does Hitachi have built-in PID recovery?

Yes. The 250kW and newer C&I models feature Anti-PID (Potential Induced Degradation) technology. It actively reverses the degradation effect on panels during the night, extending the life and yield of your solar modules.

9. Are Hitachi inverters suitable for dusty/rural environments?

Absolutely. They come with IP66 protection (Ingress Protection). The electronics are completely sealed against dust and heavy rain. The cooling system is designed to prevent sand/dust accumulation, which is a common cause of failure in Rajasthan and Gujarat projects.

10. How can I monitor my Hitachi solar plant?

Hitachi provides the Hi-Touch monitoring platform (App & Web). Using a Wi-Fi or 4G dongle supplied by Loop Solar, you can view real-time generation, check string-level health, and receive fault alerts on your phone anywhere in the world.

11. What is the warranty on Hitachi inverters?

Hitachi offers a standard 5-Year Warranty, which can be extended up to 10, 15, or 20 years. Loop Solar facilitates the warranty extension process at the time of purchase, ensuring your KUSUM project is covered for its entire loan tenure.

12. How is Hitachi's service support in India?

Hitachi has one of the widest service networks in India, with over 20 branch offices and 65+ service centers. Their "Sanand" factory ensures that spare parts are always available locally, unlike imported brands where you might wait weeks for a replacement board.

13. Do they have Arc Fault Circuit Interruption (AFCI)?

Yes. The latest Hitachi string inverters feature AI-powered AFCI. It detects dangerous electrical arcs (sparking) in the DC wiring and shuts down the system in less than 2.5 seconds to prevent fire, adding a critical layer of safety.

14. Is Hitachi listed in BIS?

Yes. All Hitachi models sold by Loop Solar are BIS Certified and compliant with IEC standards (IEC 62109, IEC 61727). This certification is mandatory for net-metering approvals and government subsidy projects.

15. Is Hitachi more expensive than Chinese brands?

Hitachi is competitively priced against Tier-1 Chinese brands like Growatt or Solis, but offers superior Japanese build quality and localized service. The slight premium (if any) is recovered through higher reliability and uptime over 25 years.

16. Can I buy a single inverter from Loop Solar?

Yes. While we specialize in bulk supply for EPCs, Loop Solar serves the entire market. You can buy a single 5kW unit for a home or 50 units of 250kW for a solar park. We have no Minimum Order Quantity (MOQ) restrictions.

17. Does Hitachi offer Hybrid (Battery) inverters?

Currently, Hitachi's primary strength in India is Grid-Tied (On-Grid) inverters. For battery-based requirements, Loop Solar recommends pairing Hitachi Grid-Tie inverters with separate AC-coupled battery solutions or choosing a different hybrid-specific brand from our portfolio.

18. Does Loop Solar help with commissioning?

Yes. For large commercial (100kW+) and KUSUM projects, Loop Solar can arrange for remote or on-site commissioning support to ensure the inverters are configured correctly for optimal performance.

19. Can I use Aluminium cables with Hitachi 250kW?

Yes. The 250kW model supports AC Aluminium cables up to 300 sqmm / 400 sqmm. This helps developers save significantly on cabling costs compared to copper, which is essential for project viability in KUSUM tenders.

21. Is the Hitachi 350kW model suitable for high-capacity PM-KUSUM projects?

Yes. The HIVERTER Si-350k-NO (350 kVA) is designed for 1500V systems, making it ideal for PM-KUSUM Component A (500kW to 2MW) and Component C (feeder solarization). Its 1500V DC input allows for longer strings, which significantly reduces overall Balance of System (BOS) and cabling costs.

22. How does the 350kW model perform in the extreme heat of Rajasthan or Gujarat?

This model is engineered for the Indian climate with a wide operating temperature range from -30�C to +60�C. It features **Smart Air Cooling** and carries an IP66 protection rating, ensuring the internal electronics remain sealed against fine desert sand and heavy monsoon rains.

23. What are the advantages of the 8 MPPT design for KUSUM utility plants?

Barren or rural lands used for KUSUM projects are often uneven. The 8 independent MPPTs (with 32 DC inputs) ensure that shading or mismatched panel orientations do not drag down the entire plant's performance. Each MPPT optimizes energy harvest with an accuracy of more than 99.9%.

24. Is the Hitachi 3kW single-phase inverter eligible for the PM-Suryaghar subsidy?

Absolutely. Hitachi residential inverters are BIS certified and meet all MNRE technical requirements for the PM-Suryaghar Muft Bijli Yojana. The 3kW single-phase model is designed to handle the voltage fluctuations typical of Indian residential grids, ensuring consistent performance and subsidy compliance.

25. Does the 3kW residential model support remote monitoring for homeowners?

Yes, the 2025-2026 residential range includes integrated Wi-Fi and mobile app support. Homeowners can track their daily solar generation and savings in real-time, which is a key requirement for modern smart homes under the national rooftop scheme.

26. What safety protections are built into the 350kW utility-scale inverter?

The 350kW model includes comprehensive safety features such as **Type II Surge Protection Devices (SPD)** on both PV and AC sides, DC reverse polarity protection, anti-islanding protection, and string current monitoring to ensure utility-scale reliability.

20. How fast can I get a Hitachi inverter in Lucknow or Jaipur?

Very fast. Loop Solar stocks Hitachi inverters in our Lucknow and Jaipur warehouses. We can typically deliver within 24-48 hours to sites in UP and Rajasthan, avoiding the long transit times from factory locations.
