A diesel generator can be a practical power source for a rural property, a worksite or selected appliances during an outage. Choosing the right one starts with understanding what you need to run, how long you need power and how the generator will be connected.
The MaxWatt diesel generator range includes models with different output capacities and starting features. Rather than choosing on engine type alone, it helps to compare continuous power, fuel tank capacity, controls and servicing requirements.
Here are five practical benefits to consider when deciding whether a diesel generator suits your needs.
1. Useful Runtime for Longer Jobs
When power is needed for several hours, runtime matters. A generator with enough fuel capacity for the planned load can reduce interruptions for refuelling and make it easier to organise a working day or prepare for an outage.
For example, the MaxWatt MX6000DAS diesel generator has a 14.5 litre tank. Its datasheet lists up to 15 hours of runtime at 50% load and eight hours at 100% load. Actual runtime depends on the equipment connected and operating conditions.
Fuel economy should be assessed using figures for the specific generator and load. Diesel power does not guarantee a particular saving over petrol, and a larger tank does not automatically mean a more efficient engine. Compare runtime at equivalent loads alongside fuel prices, purchase cost and servicing needs.
2. Power Options for Different Loads
A useful generator needs enough continuous output for the equipment you plan to operate. It also needs to accommodate the additional power some appliances and tools require when starting.
The MaxWatt MX10000DSE diesel generator is rated at 8,000W continuous output and 8,500W maximum output in its datasheet. This provides a different capacity option from the MX6000DAS, which is rated at 4,500W continuous and 5,000W maximum.
Continuous output is the figure to use when assessing ongoing demand. Maximum output should not be treated as power available for continuous operation. Motors, pumps and compressors may require substantial starting power, so check the equipment specifications before choosing a generator.
MaxWatt’s generator selection guides can help you work through your requirements. Outlet ratings and the proposed connection also matter, especially when several loads will run together.
3. Practical Starting and Control Features
Starting features can make a difference when a generator is used regularly or forms part of a planned backup system. Electric start offers a convenient way to start the engine, provided the starting battery is maintained.
The MX6000DAS and MX10000DSE datasheets both list electric start and two wire auto start. Two wire auto start can be useful with compatible external control equipment, but it does not mean the generator automatically powers a building as supplied.
For an off grid system, ask your installer to confirm the generator’s compatibility with the inverter or charger, the control connection and the charging load. A diesel generator supplies electrical power to a compatible system. It does not connect directly to portable solar panels.
4. A Backup Power Option Away from Mains Supply
A diesel generator offers another way to supply electricity when mains power is unavailable. That may be useful on a property without a grid connection or during an outage, provided the generator is correctly sized and operated safely.
Start by deciding which loads are essential. Keeping selected appliances running may require less capacity than powering an entire property. The connection method should be planned before the generator is needed.
A licensed electrician must arrange any connection to a building’s wiring using suitable changeover equipment. Never feed generator power into a wall socket. Operate the generator outdoors, away from doors, windows and vents, because its exhaust contains carbon monoxide.
Diesel fuel does not remove the risks of fire, electrical injury or exhaust exposure. Follow the operating manual and keep the generator dry. An outlet’s IP rating does not establish that the complete generator is safe to operate in rain.
5. Maintenance That Can Be Planned Around Your Usage
Maintaining a generator before it is needed helps you identify problems early. A diesel engine does not use spark plugs for ignition, but it still needs regular attention to its oil, filters, fuel system and starting battery.
Follow the servicing intervals for your model rather than assuming every diesel generator has the same requirements. Operating hours and conditions affect the attention it needs. Check for leaks, damaged connections and obstructions to cooling airflow as directed by the manufacturer.
Use the MaxWatt operation manuals for the correct checks, oil specifications and servicing instructions. Leave electrical repairs and major servicing to qualified technicians.
Choosing a MaxWatt Diesel Generator
The best choice depends on your equipment and setup. Consider continuous output, starting demand, runtime, noise, transport arrangements and the controls your installation requires.
Noise deserves attention when choosing a location. The MX6000DAS and MX10000DSE datasheets list noise levels of 75 to 85 dB. Consider nearby homes and work areas, while maintaining the ventilation and clearances required for safe operation.
Browse the diesel generators to compare the models currently listed. If you need help narrowing down the options, contact MaxWatt with details of your equipment, expected operating hours and proposed connection.
Frequently Asked Questions About Diesel Generators
Are diesel generators always cheaper to run than petrol generators?
No. Running costs depend on the generator, its load, fuel prices and servicing requirements. Compare fuel consumption or runtime at equivalent loads rather than assuming diesel will always cost less.
How do I choose the right size diesel generator?
Check the combined running demand of the equipment you want to use and allow for its starting requirements. Compare these with the generator’s continuous and maximum output ratings, then confirm that the outlets and connection suit the installation.
How long can a MaxWatt diesel generator run on one tank?
Runtime varies by model and load. The MX6000DAS datasheet lists up to 15 hours at 50% load and eight hours at 100% load from its 14.5 litre tank. Treat published runtime as a guide, since actual conditions affect fuel use.
Can a diesel generator provide backup power for a home?
Yes, when its capacity and connection suit the intended loads. Any connection to the home’s wiring must be arranged by a licensed electrician using suitable changeover equipment. Never connect a generator to a wall socket.
Can a MaxWatt diesel generator support an off grid solar system?
A compatible model can provide backup through suitable inverter or charging equipment. Have your installer confirm electrical compatibility, charging demand and any auto start controls before connecting it.
Are MaxWatt diesel generators suitable for sensitive electronics?
Confirm the power quality requirements of your devices against the specifications for the exact generator. Automatic voltage regulation alone does not establish suitability for every electronic device. Ask MaxWatt to confirm the model’s harmonic distortion specification if your equipment requires it.
What maintenance does a diesel generator need?
Follow the model’s operating manual for oil changes, filter servicing, fuel system checks and battery care. Keep cooling airflow clear and arrange qualified servicing where required. Service intervals should be based on the manufacturer’s instructions and your operating conditions.
