A 15 kVA single-phase alternator is used when applications require a relatively high-capacity AC supply on single-phase power. These alternators are commonly used in backup power systems, workshops, agricultural setups, construction applications, temporary installations, and diesel generator assemblies.
The important part is that a 15 kVA alternator is only the electrical generating component. It needs a suitable prime mover, such as a diesel engine, to rotate the alternator and produce electricity.
If you are comparing a 15 kVA single-phase alternator in India, price alone should not decide the purchase. Voltage, speed, winding material, excitation/AVR arrangement, bearing configuration, insulation class and compatibility with the engine all matter.
15 KVA Single-Phase Alternator Price in India
Current Indian listings show a fairly wide price range. Some locally manufactured or supplier-listed 15 kVA alternators are advertised around ₹35,000–₹48,000, while a branded MNE unit is currently listed at ₹49,559 including taxes. Another supplier lists it at ₹65,000. Treat these prices as listed prices rather than a universal market price.
The final amount can change based on GST, transport, configuration, mounting arrangement, bearing type, AVR, winding construction, and the seller’s quotation.

KOEL KSA.1754.10.0.00 — 15 KVA Single-Phase Alternator
The KOEL KSA.1754.10.0.00 is one of the better-documented options in this category because its specifications are available directly from the manufacturer.
KOEL specifies a 15 kVA rating, 1500 RPM speed and single-phase operation. Its voltage range is 160–240 V, and the listed power factor is 0.8. The alternator uses a copper winding and cast-iron body, with an SS410 shaft.
For a buyer who wants manufacturer documentation rather than relying entirely on a marketplace listing, the KOEL model is worth investigating.
The official page does not list a retail price, so you’ll need a current dealer quotation.

Other 15 KVA Alternators in the Indian Market
Several other supplier listings for 15 kVA single-phase alternators appear. Power Care, for example, lists a 15 kVA AC alternator at ₹65,000. However, the listing specifies 420 V while identifying the product as single-phase.
Confirm that combination with the seller before purchase, because voltage configuration is one of the first things that must match the intended electrical system. Superking also lists a 15 kVA single-phase AC alternator at approximately ₹35,000.
Its listing gives 415 V and an industrial application, so the buyer should similarly confirm the actual winding and output configuration. These examples show why a low advertised price does not necessarily mean that two 15 kVA alternators are directly interchangeable.
What Does 15 KVA Actually Mean?
The “15 kVA” rating describes the alternator’s apparent power capacity. It should not automatically be interpreted as 15 kW of usable real power. For example, at a power factor of 0.8:15 kVA × 0.8 = 12 kW. So, an alternator operating at a power factor of 0.8 corresponds to approximately 12 kW of real power.
The actual load that can be connected depends on the alternator’s rating, power factor, engine capacity, operating conditions and the characteristics of the connected equipment.
At 230 V, a 15 kVA single-phase alternator corresponds to roughly 65 A at unity power factor. At 0.8 power factor, the current associated with 15 kVA would be about 87 A. Always check the exact operating current against the manufacturer’s electrical specifications. Things to Check Before Buying a 15 KVA Alternator
1. Output voltage – For a typical Indian single-phase installation, 230–240 V is a common requirement. Don’t assume every “single-phase 15 kVA” listing has the same voltage. Some current listings show 415 V or 420 V, so confirm the output configuration before placing an order.
2. Engine compatibility – If the alternator is being purchased separately for a diesel generator, check the engine’s rated speed, available shaft power, coupling arrangement and mounting dimensions. A 1500 RPM alternator, for example, needs to be coupled to a suitable prime mover operating at the required speed.
3. AVR and voltage regulation – An automatic voltage regulator can help maintain output voltage as the electrical load changes. Check whether the particular model uses an AVR, transformer excitation or another regulation arrangement.
4. Winding material – Copper windings are commonly specified in the Indian products researched for this article. However, “copper winding” should not be the only purchasing criterion. The insulation system, thermal rating, construction quality and manufacturer documentation also matter.
5. Bearing arrangement – Alternators may be available with one or two bearings depending on their construction and coupling arrangement. Make sure the bearing and shaft configuration matches the intended engine or prime mover.
6. Insulation class – Insulation class provides information about the thermal capability of the winding insulation system. For example, the Chandra listing specifies Class H insulation.
7. Service and spare parts – For a generator used regularly in a business, workshop or commercial installation, local service availability can matter as much as the initial purchase price. Ask the supplier about bearings, AVR components, rectifiers and other replacement parts before finalising the purchase.
Which 15 KVA Alternator Should You Consider?
There is no single universal choice because the appropriate alternator depends on the installation.
The KOEL KSA.1754.10.0.00 is worth considering when manufacturer documentation and a clearly specified 15 kVA/1500 RPM single-phase configuration are priorities.
The MNE AE41E is an option for buyers looking for a currently listed 220–240 V brushless unit with two bearings. Its ₹49,559 tax-inclusive listing also gives a useful current price reference.
The Chandra 15 KVA is another locally listed option, with 230 V, 1500 RPM and Class H insulation specified and a listed price of ₹48,000. Lower-priced listings such as the Superking model can be worth investigating when budget is important, but confirm the exact voltage and winding configuration before comparing them directly with 230 V models.
In other words, compare the complete specification, not just the ₹/kVA figure. Common Applications: A 15 kVA single-phase alternator can be considered for applications such as:
- Backup power systems
- Workshops
- Agricultural installations
- Temporary construction power
- Event and tent
- decoration setups
- Small commercial installations
- Generator sets requiring single-phase output
The suitability depends on the actual connected load and the characteristics of the prime mover.
