Investing in a genset (generator set) is a strategic decision for any home, business, or industrial facility. Whether it’s to ensure reliable power backup, maintain operations during outages, or safeguard mission-critical equipment, a genset provides an essential layer of protection.
However, the process of selecting the right generator is far more complex than comparing prices or power ratings. Many buyers—especially first-timers—make avoidable mistakes that result in poor performance, high fuel costs, frequent breakdowns, or even non-compliance with CPCB IV+ norms.
As a leading genset manufacturer in Maharashtra, Shyam Global has seen these issues firsthand. Here’s a look at the top 5 common mistakes to avoid when buying a genset, and how you can make a smarter, future-ready investment.
🔌 1. Miscalculating Power Load Requirements
One of the most common and costly errors is selecting a genset without properly calculating your power load. Many buyers base decisions on a few appliances or rough estimates, without factoring in starting surges and total running load.
- Undersized gensets can overload and trip frequently.
- Oversized gensets result in unnecessary fuel consumption and capital expense.
✅ Solution:
Conduct a detailed load analysis, considering both continuous and peak loads. For operations running motors or compressors, remember to account for high startup currents. Consulting a diesel genset expert or certified technician can help prevent this error.
⚡ 2. Selecting the Wrong Phase Type
Choosing between a single-phase and three-phase genset is critical and depends on the application. This is often misunderstood or overlooked during the buying process.
- Single-phase gensets are typically used for residential and small commercial needs (up to ~20 kVA).
- Three-phase gensets are designed for industrial, commercial, or heavy-duty operations.
Choosing the wrong type leads to inefficiencies, limited scalability, and potential damage to sensitive equipment.
✅ Solution:
Assess your site’s power infrastructure and future growth. If you’re in manufacturing, healthcare, or commercial operations, a three-phase diesel genset will offer better load handling and stability.
⛽ 3. Ignoring Fuel Type and Long-Term Costs
Another frequent mistake is choosing a genset based only on initial cost, without evaluating the fuel type, operating costs, or environmental factors.
- Diesel gensets are robust, efficient, and widely used in India for their fuel availability.
- Gas gensets offer cleaner emissions, quieter operation, and are ideal for locations with a stable gas supply.
✅ Solution:
Choose between diesel or gas gensets based on availability, emissions, and expected usage. Always calculate the total cost of ownership (TCO), not just purchase price, especially for long-term industrial use.
🌍 4. Overlooking Regulatory Compliance (CPCB IV+ Norms)
Environmental regulations are getting stricter, especially in industrial and urban zones. Buying a genset that doesn’t meet current emission standards—like the CPCB IV+ norms in India—can lead to fines, shutdowns, or rejection of installation permits.
✅ Solution:
Always opt for CPCB IV+ compliant gensets from certified manufacturers. Shyam Global offers a full range of eco-friendly generators built to meet government norms and ensure uninterrupted operations without legal risks.
🛠 5. Neglecting After-Sales Service and AMC Options
Many customers fail to consider after-sales service, assuming any local technician can manage routine maintenance. In reality, poor service access or a lack of genuine parts can result in prolonged downtime and increased repair costs.
✅ Solution:
Choose a genset provider that offers strong after-sales support, Annual Maintenance Contracts (AMCs), and on-site technical assistance. As a trusted genset manufacturer in Maharashtra, Shyam Global ensures reliable service, spare part availability, and preventive maintenance for long-term efficiency.
✅ Final Thoughts
Purchasing the right generator isn’t just about meeting current needs—it’s about future-proofing your operations. From calculating load accurately, selecting the correct phase and fuel type, ensuring CPCB compliance, to securing reliable service and AMC coverage—each step matters.
Avoiding these common mistakes helps ensure that your genset offers consistent performance, fuel efficiency, and compliance for years to come.Whether you’re looking for a diesel genset for industrial use, a gas genset for cleaner operations, or CPCB IV+ certified backup systems—Shyam Global provides trusted, cost-effective solutions backed by local service and expertise across Maharashtra.
