Steel Products SP-GD650E Diesel Generator

Steel Products SP-GD650E Diesel Generator

The SP-GD650E 6,500 watt diesel powered generator with electric start from Steele Products utilizes the advantage of the parent companies economies of scale and provides the best value in its category. Steele Products is a subsidiary of JD North America which is a part of the JD Group. It has its manufacturing facilities in China and is a part of a group of companies that manufacture over one million engines annually.

This generator has a 10 hp air cooled diesel engine and can deliver 5000 watts of continuous power while being able to surge up to 6500 watts. Being a portable generator it can be used as a back up power source for your home in times of power outages, it can also be used at job sites where there is a need of electricity to run power tools. This model is not CARB compliant.

Power Output and Generation

The SP-GD650E diesel powered portable generator is capable of supplying 5000 watts of continuous power while being able to surge up to 6500 watts. It provides 42 amps @ 120V and 21 amps at 220V.

This generator is powered by an air cooled 10 hp single cycle 4 stroke diesel engine. The engine runs at the typical 3600 rpm for generation, but for a diesel this is considered by some to be on the fast side. It has a low oil sensor and light and will shut down on low oil.

Outlet Configuration:

The unit is set up with a 120/240V switch to utilize the circuit. This will limit use in the 240V position to the 21A of available power.

on the 120V side you have the 5-20R and L5-30R as well as the L14-30R to use in supplying power. Of course you are restricted by the circuit breakers for each outlet but can use them up to the full 42A capability of the generator.

The 12V DC circuit is available for charging batteries. In their manual they indicate that it is to be used for charging the generators battery. Since no wiring diagram was available we could not verify that the battery was not on it’s own charging circuit. This seems very odd that it isn’t configured to charge it’s self.

Also indicated in the manual is that you should not be using the AC circuits when using the DC circuit. Again this seems to be an odd requirement and defeats the purpose of having a generator this large which can only handle a DC circuit without using AC. One might be better off getting an battery charge that could plug to the AC circuit.

I have an inquiry to Steele Products for clarification.

Fuel Type and Noise Levels:

The SP-GD650E portable engine uses diesel as fuel and has a fuel tank capacity of 4 gallons. It can run for 9 ½ hours on one tank of fuel at 50% load capacity.

Noise:

This generator is quiet for a diesel generator and produces only 70 Db of noise level when it is running. The enclosure helps to keep the noise level down to that of similar sized gas powered generators.

Dimensions and Weight

The overall dimensions of this generator are 37.4 x 21.6 x 31.1 inches ( L x W x H ) and it weighs in at 372 lbs. and with 4 gallons of diesel (~7 lbs per gal) about 400 lbs.

Typical Uses and Needs

The SP-GD650E diesel powered portable generator is has 9.5 hrs on half load with rated power to 5kW. This makes this generator useful as a backup power source for your home in times of power outages. Being portable means that this generator can also be used to supply electrical power wherever you may need it, like a job site to power electrical tools or even to power electrical appliance in your cabin.

Because it is heavy (400lbs) portability isn’t as easy as pulling it around like the less heavy gas generators. On flat surfaces like garage concrete it can be pushed around and moved to meet needs, however, moving to job sites and the like will take effort to trailer or with ramps to get it transported.

Display & Control Panel, Start-up

The control panel of the SP-GD650E diesel generator is located on the side of the generator. When you face the control panel you will find the Electric Starter switch at the top left of the panel, next to it to the right you have two lights the one on the top turns On when the generator is running and below it you have the Low Oil indicator light.

To the right of the lights you have the Voltmeter and to the right you have the Hour meter below which you have the 120V/240 V toggle switch. To the right you have the Main Circuit breaker.

Below the Starter switch you have two 120V 20 amp receptacles and next to them on the right you have the twist lock 120V L5 30 amp receptacle. Next to this outlet to the right you have 2 circuit breakers the top one controls the 20 amp outlets and the lower one controls the twist lock outlet.

Moving on to the right you have the 120V/240V outlet and below that you have the Ground terminal. To the right of this terminal you have the 12V DC terminals and a circuit breaker above them which controls these terminals.
