Gas Generators: LPG Cylinder or Natural Gas

For a retail business, every blackout costs sales: the POS terminal that goes down, the walk-in cooler that loses temperature, the office that drops offline. A gas generator handles that everyday backup without relying on diesel or gasoline: it connects to an LPG cylinder or a natural gas service line, and the fuel can sit in standby for months without degrading.

There are two sizes, both with the same 999 cc V-twin engine and sound-attenuated aluminum enclosure. The 15 kVA covers an office, medical practice or small shop; the 20 kVA runs a retail business with several air conditioners, display refrigerators and walk-in coolers. Both are single-phase 120 / 240 V. If your load is three-phase or exceeds 20 kVA, the next step up is our diesel generators from 24 to 152 kVA.

Gas, Diesel or Lithium Battery?

All three provide backup power, but they solve different problems. Here's how the technologies we distribute compare:

Backup Power Comparison
	Gas Generator	Diesel Generator	Lithium Kit
Fuel	LPG cylinder or natural gas	Diesel	None: charges from the grid or solar panels
Fuel storage	Doesn't degrade: the generator can sit for months and still start	Diesel must be kept clean and rotated	N/A
Noise	Low, sound-attenuated enclosure	Open-frame or sound-attenuated, depending on model	Silent
Ratings available at ENERMAQ	15 and 20 kVA single-phase	24 to 152 kVA, single- and three-phase	3 and 12 kW
Backup runtime	As long as there's gas; on piped supply, nothing to refill	As long as there's diesel in the tank	A few hours, depending on the battery bank
Best application	Retail, offices and medical practices with frequent outages	Industry, buildings, job sites and three-phase loads	Short outages with no noise or fuel

The short rule: if your load fits within 20 kVA single-phase and you have gas available, a gas generator is the easiest to maintain. If you need three-phase power, more capacity or a job site without utilities, go diesel. And if outages last only a few hours and you want complete silence, the lithium backup kit.

Continuous vs. Standby Rating: Which One to Use

Each spec sheet lists two ratings per fuel. The continuous rating is what the generator sustains hour after hour; the standby rating is the maximum it can carry for limited periods. The model name (15 or 20 kVA) matches the standby rating on natural gas, so always size against the continuous rating for the fuel you'll use.

kVA Rating by Fuel
Model	LPG continuous	LPG standby	Natural gas continuous	Natural gas standby
15 kVA · GGG-015-LPG-NG	15	16.5	13.5	15
20 kVA · GGG-020-LPG-NG	20	22	18	20

Example: if your shop totals 16 kVA of load and runs on natural gas, the 15 kVA unit falls short (13.5 continuous) and the 20 kVA leaves you headroom (18 continuous). If you don't have the total handy, our guide to sizing your generator in kVA walks you through it, motor starting loads included.

What to Plan for Before Installation

The gas connection is handled by qualified personnel, with the correct regulator for LPG cylinders or natural gas.
With LPG cylinders, runtime depends on how many you connect and on the load. We'll calculate how many you need for the backup hours you're after.
Location: outdoors or in a well-ventilated space, away from windows and air intakes. The enclosure is rated IP23 (rain-protected) and has a 1.40 × 0.67 m footprint.
The automatic transfer switch is what starts the generator on its own when the power goes out. With rated currents of 62.5 A and 83.33 A, both units fit a 100 A panel; see our ATS transfer panels.

Frequently Asked Questions

Does the gas generator run on an LPG cylinder?

Yes. It runs on liquefied petroleum gas (LPG), the fuel in standard gas cylinders, or on natural gas straight from the utility line. Output is slightly higher on LPG: 15 or 20 kVA continuous, versus 13.5 or 18 kVA on natural gas. The gas connection must be made by qualified personnel, with the correct regulator for the fuel you'll be using.

How much does a gas generator cost in Venezuela?

It depends on the model, the fuel and the installation you need: LPG cylinders or a natural gas service line, regulator and automatic transfer switch. We don't publish prices because we quote the complete package for your application. Message us on WhatsApp with what you need to back up and we'll reply with a formal quote and delivery to your state.

Gas or diesel generator: which is the better choice?

If your load fits within 20 kVA single-phase and you have gas available, a gas generator is the easiest to live with: the fuel doesn't degrade in storage, it burns clean and the enclosure is quiet. If you need three-phase power, more than 20 kVA, or a unit for a job site with no utilities, go with a diesel generator; ENERMAQ offers them from 24 to 152 kVA.

How long does an LPG cylinder last?

It depends on the connected load and the cylinder size, so there's no single honest figure. On piped natural gas, there's nothing to refill. Send us your equipment list and the backup hours you need on WhatsApp, and we'll calculate how many cylinders you'll need.

Does it start automatically when the power goes out?

Yes, when installed with its automatic transfer switch (ATS). The generator has 12 V electric start and an electronic controller; the ATS detects the outage, starts the unit and transfers the load, then switches back to utility power when it returns. At 62.5 A for the 15 kVA and 83.33 A for the 20 kVA, both fit a 100 A panel.

Is it safe for computers and sensitive electronics?

Yes. The automatic voltage regulator holds voltage within ±5% and harmonic distortion stays below 5%: a pure sine wave, suitable for computers, servers, POS terminals, security cameras and modern appliances.

Is it loud?

It's sound-attenuated: an aluminum enclosure with fire-retardant acoustic insulation, designed for installation near neighbors. Even so, install it outdoors or in a well-ventilated space, away from windows and air intakes, because of the exhaust fumes.

Does it come with a warranty and technical service?

Yes. It's a new unit with a factory warranty, genuine spare parts and in-country technical service, backed by GENPAR and by ENERMAQ as authorized distributor.

Complete Your Backup System

The gas generator covers retail and office backup. For three-phase loads or a job site with no grid power, go with a diesel generator; for short, silent outages, a lithium kit.
