Mahindra Powerol 1010 kVA & 1250 kVA DG set
Mahindra’s biggest diesel generators sit in the 1000 kVA class. The two models share one 30.5-litre Perkins engine, one frame and one canopy, but they are built for different jobs. Read the rating before you read the number.
- Prime · unlimited hours
- 1010
- kVA · 4008-30TAG2 · 1,208 BHP
- Standby · 500 h a year
- 1250
- kVA · 4008-30TAG3 · 1,481 BHP
Quick answer
- 1010 kVA (M1010DR) is a prime rating: unlimited hours at an 80% average load.
- 1250 kVA (M1250DR) is a standby rating: up to 500 hours a year, no overload.
- Both use a Perkins 4008-30 engine: 8 cylinders in-line, 30.5 litres, 1500 rpm.
- Canopied size: 6900 × 2440 × 2750 mm; weight about 10.9–11.3 tonnes.
- Fuel tank: 990 L (integrated canopy) or 905 L (cap-on canopy).
- Price, fuel use, noise and emission tier are not published by Mahindra.
What is the difference between the 1010 kVA and the 1250 kVA? Same engine block, 23% more power.
The power rises by almost a quarter while the weight rises by under 5%. That gap is what Mahindra means by “highest power to weight ratio”. The price of the extra power is the duty: the 1250 kVA rating holds for standby use only.
π/4 × 16² × 19 cm × 8 = 30,560 cc
We checked the brochure’s 30.5 L against its own bore and stroke. It adds up.
Which rating does your site need? Move the sliders to your load.
Prime means unlimited hours at an average of 80% of the rating, with 10% extra for one hour in every twelve. Standby means up to 500 hours a year at the same 80% average, and nothing above the rating.
Both ratings cover this.
The 1250 kVA standby gives the most headroom for backup. The 1010 kVA prime also keeps you covered if outages ever run past 500 hours a year.
Large motors draw several times their running load when they start. If you have lifts, chillers or pumps, work out your peak first with the load calculator.
How big is a 1000 kVA DG set? A 20-foot container with 842 mm added on.
The dashed outline is a standard 20-ft shipping container (6058 × 2438 mm). The integrated canopy matches its width almost exactly and stands 159 mm taller. Plan the crane, the plinth and the gate around 11 tonnes.
Both ratings share every dimension. Weights shown are 1010 kVA–1250 kVA. Fuel tank: 905 L cap-on, 990 L integrated. The open set has no tank figure in the brochure.
