Mahindra 82.5 kVA Silent DG Set

The Mahindra MP-82.5KVA-DG is a premium power backup solution designed for the Indian market, where reliable electricity is critical for business continuity. This 82.5 kVA generator (which equals 66.0 kW at a 0.8 power factor) is a three-phase system delivering 415V at 50Hz, perfectly suited for running industrial motors, hospital equipment, and commercial HVAC systems. It is powered by the Mahindra 4155GM-C2 4-stroke inline engine, a 1835cc water-cooled workhorse that operates at 1500 RPM. This model is fully CPCB-II compliant, meeting the strict emission and noise norms (75 dB at 1 meter) mandatory in India since 2014. For facilities dealing with frequent outages from providers like BESCOM or MSEDCL, this generator offers a 12-hour runtime on a full 100L tank. It features advanced safety systems including Low Oil Shutdown, Earth Leakage Protection, and Overload Protection. The brushless alternator uses AVR technology for stable voltage regulation, protecting sensitive electronics from surges. Designed for continuous duty, the steel silent canopy allows for installation in residential complexes and hospitals where noise restrictions are high. With a 2-year warranty on both the engine and alternator, this Mahindra DG set is a trusted investment for Indian entrepreneurs and facility managers seeking to eliminate downtime during summer peak failures and scheduled grid maintenance.

Quick Answer

Yes, it is a high-value investment because Mahindra has one of the best resale values and service penetrations in India. Compared to an expensive solar-plus-battery setup of the same capacity, this DG set provides immediate, high-amperage power for heavy loads at a much lower initial capital expenditure, making it the most viable choice for industrial backup.

✓Hospital emergency backup for ICUs and life-support systems during grid maintenance.
✓Continuous power supply for plastic injection molding factories in industrial estates.
✓Uninterrupted backup for luxury residential societies to run lifts, pumps, and common area lighting.

In India, silent generators are the standard for any urban or semi-urban installation due to RWA rules and CPCB-II regulations. While open-frame models might be cheaper, they are restricted to remote construction sites; the silent canopy of the Mahindra 82.5 kVA provides the necessary weather protection and noise reduction for legally compliant operation.

✓ Who Should Buy

  • •This generator is primarily purchased by Indian SME factory owners, mid-sized hospitals, luxury banquet halls, and residential apartment complexes. It is also a favorite for petrol pump owners and large retail showrooms that cannot afford even a 5-minute outage during peak shopping hours.

✕ Who Should Avoid

  • •Spaces or usage requirements exceeding residential rated capacity.
  • •Installations prioritizing minimum capital expenditure over high-efficiency performance.
  • •Unstable grid conditions exceeding the functional threshold of Standard power cycle.
  • •Environments incompatible with generators physical and thermal dissipation specs.
Product Overview
The Mahindra MP-82.5KVA-DG is a high-performance, silent diesel generator engineered specifically for the demanding Indian power landscape. As DISCOMs like MSEDCL, BESCOM, and DHBVN struggle with summer peak demand and scheduled load shedding in Tier-2 and Tier-3 cities, this 82.5 kVA (66 kW) three-phase unit provides a rock-solid energy bridge. Built with a field-proven 4-cylinder water-cooled engine and a CPCB-II compliant acoustic enclosure, it offers a noise level of just 75 dB, making it suitable for both industrial zones and sensitive commercial areas. Its 100L fuel tank and 7.8 L/hr consumption rate ensure your operations continue seamlessly during extended outages or UPS handover gaps.

Engineering Analysis
Technically, the MP-82.5KVA-DG utilizes the Mahindra 4155GM-C2 engine, a 4-cylinder inline configuration that maximizes torque and fuel efficiency through a mechanical governor. The displacement of 1835 cc paired with a water-cooled system allows the unit to maintain thermal stability even in the 45°C+ temperatures of Indian summers. The electrical side features a high-efficiency brushless alternator with Class F insulation and 100% copper winding, ensuring longevity and minimal heat loss. The inclusion of an Automatic Voltage Regulator (AVR) is critical for Indian users who need to power a mix of heavy machinery and sensitive digital control panels. The 120A current capacity across three phases provides ample headroom for starting inductive loads such as elevators or centralized air conditioning units.
