Supply, installation, battery replacement, repair, and annual maintenance contract (AMC) for Hitachi Hi-Rel UPS systems across Mumbai, Thane, Navi Mumbai, and Maharashtra. Specialists in industrial and three-phase Hi-Rel UPS installations.
Hitachi Hi-Rel Power Electronics — formerly Hi-Rel Electronics, acquired by Hitachi — is one of India's most established UPS manufacturers, headquartered in Ahmedabad. The company occupies a rare position in the Indian market: an India-headquartered manufacturer competing credibly in the premium industrial and enterprise UPS segment alongside global names such as Eaton, Vertiv, and APC.
Hitachi Hi-Rel UPS systems are engineered specifically for Indian operating conditions. The wide input voltage range of 110–300V accommodates the significant voltage fluctuations common in Indian industrial and semi-urban environments, while the transformer-based configurations deliver galvanic isolation that is essential for manufacturing, healthcare, and mission-critical applications. These are not entry-level devices — they are professional-grade systems designed for continuous duty in demanding environments.
The brand has a substantial installed base across Indian data centres, telecom tower infrastructure, banking networks, government facilities, and large manufacturing units. Hitachi Hi-Rel's national service infrastructure, combined with their India-specific engineering, makes them a strong consideration for organisations that prioritise local accountability and India-manufactured equipment — particularly in government procurement contexts where domestic manufacturing preference applies.
Sukhai UPS Solutions supplies, installs, services, and maintains Hitachi Hi-Rel UPS systems in Mumbai, Thane, Navi Mumbai, and across Maharashtra. Our engineers are experienced with both single-phase and three-phase Hi-Rel systems, including the transformer-based configurations used in industrial and isolation-critical installations.
Hitachi Hi-Rel offers a comprehensive range of online double-conversion UPS systems from small office units through to large modular data centre platforms. All models use IGBT technology and are designed for Indian power conditions.

Hitachi Hi-Rel has built its reputation on engineering UPS systems that perform reliably in the specific power and environmental conditions found across India. Here is what sets them apart in the industrial and enterprise segment.
Hitachi Hi-Rel UPS systems are manufactured in India, making them eligible for government procurement preferences and domestic manufacturing requirements. Supply chain, spare parts, and service infrastructure are all India-based, reducing lead times and import dependencies.
Hi-Rel UPS systems accept input voltages from 110V to 300V — one of the widest input ranges in the industry. This matters enormously in Indian industrial areas, rural connections, and regions where voltage fluctuation is severe and unpredictable.
Hi-Rel's transformer-based UPS configurations provide galvanic isolation between input and output, protecting sensitive loads from common-mode noise, ground faults, and transient spikes. Essential for CNC machines, medical imaging equipment, and manufacturing control systems.
Hitachi Hi-Rel systems have an extensive installed base in Indian telecom tower infrastructure and data centres. The modular UPS platform supports concurrent maintainability and scalability — adding capacity without downtime as power requirements grow.
Hitachi Hi-Rel has a well-developed service presence across Western India including Mumbai, Thane, Pune, Nashik, and Gujarat. For organisations in Maharashtra, this translates to faster on-site response and better local spares availability compared to some global brands.
Hi-Rel UPS systems use industrial-grade IGBT modules, capacitors rated for Indian ambient temperatures, and robust mechanical construction suited to dusty, high-humidity environments. This matters for factory floor installations where consumer-grade or light-commercial UPS systems often fail prematurely.
Sukhai UPS Solutions provides end-to-end Hitachi Hi-Rel UPS services across Mumbai, Thane, Navi Mumbai, and Maharashtra — from initial supply and commissioning through to long-term AMC support.
We supply and install Hitachi Hi-Rel UPS systems across the full range — single-phase office units through to large three-phase industrial systems. Our team handles site survey, foundation preparation, cabling, earthing, commissioning, and load testing. We coordinate electrical works and ensure the installation meets IS and manufacturer specifications.
SMF/VRLA battery replacement for all Hitachi Hi-Rel UPS models. We test existing batteries under load, source compatible replacement cells, perform the swap with minimum downtime, verify charge and backup time, and arrange responsible disposal of end-of-life batteries. We work with approved battery brands to maintain UPS warranty compliance.
Our engineers are trained in Hitachi Hi-Rel UPS fault diagnosis and component-level repair. We cover IGBT module failures, rectifier and inverter faults, control card and PCB issues, display and interface problems, fan and cooling system faults, and transformer faults in isolation models. Fast diagnosis, genuine spare parts, and documented repair records.
Structured AMC plans for Hitachi Hi-Rel UPS fleets — scheduled preventive maintenance visits, battery health monitoring, thermal imaging, load testing, firmware checks, and priority breakdown response. Available for single units and multi-site fleet contracts across Mumbai and Maharashtra.
Planned preventive maintenance visits to Hi-Rel UPS installations — cleaning, thermal checks, connection torque verification, capacitor inspection, battery state-of-health testing, and reporting. Preventive visits are the most cost-effective way to extend Hi-Rel UPS service life and avoid unplanned failures in critical environments.
Specialist commissioning for large three-phase and transformer-based Hitachi Hi-Rel UPS installations in industrial facilities. We handle parallel commissioning, static bypass testing, generator synchronisation checks, load bank testing, and handover documentation. Suitable for manufacturing plants, data centres, and critical infrastructure projects.
Hitachi Hi-Rel UPS systems are particularly well suited for the following applications and procurement contexts:
For small office and IT loads where compact form factor and global warranty coverage are priorities, we may recommend APC or Eaton instead. We will advise honestly based on your specific load, site, and budget — not on which product carries the highest margin for us.
