I was interested in buying the Generac GP17500E. I did my homework and believe it is the one for me. The questions I have are: 1. Can I convert it to propane? 2. How long will a 15lb propane tank last on this generator if I'm not powering the whole house and just the bare necessities? Thank you Ryan
Ryan

Answer
Thanks for your inquiry.

We at Power Equipment Direct do not recommend converting your gasoline portable generator to an alternative fuel and doing so will void the manufacturer’s warranty and may cause damage to the generator itself. These conversions are not recommended by any of the generator manufacturers.

Gasoline has an Ignition Point of 475–536 °F. When a generator is manufactured to run solely on gasoline these temperatures are taken into consideration and the engine components are made to handle these temperatures.

Propane (LP) has an Ignition Point of 920-1020°F and Natural Gas (NG) has an Ignition Point of 900–1500°F. These higher temperatures will cause damage over time on any “gas only” powered engine.

The following guidelines cover Honda engines (Also applies to other engine manufacturers) modified to run on fuels other than the one for which they were designed, such as converting an engine to run on propane (LP) or natural gas (NG).


• Honda gasoline engines are certified to operate on unleaded fuel with a pump octane rating of 86 or higher, containing no more than 10% ethanol (E10).

• Any change to the original configuration of a certified Honda engine is a potential violation of the Clean Air Act prohibition against tampering (40 CFR §1068.101(b)(1)). The tampering prohibition is important because poorly designed and installed modifications can increase emissions.

• The Clean Air Act prohibits anyone from removing or rendering inoperative any device or design element installed on engines in compliance with regulations. These actions are considered tampering, which carries a civil penalty up to $37,500 for each engine or equipment in violation.

• Engines converted by a third party (OEM, dealer, converter, etc.) to run on a different fuel type must be recertified with the EPA on the new fuel to comply with applicable emission standards. The third party must recertify under a new family and notify Honda to not include the modified engines in the original family.

• Converted engines to be sold for use in California must meet CARB requirements and the converter must obtain approval from CARB. EPA certificates or tampering exemptions will not satisfy the requirement for CARB certification.

• Once certified, the third party must remove the Honda emission control label and apply a compliant emission control label for the new fuel indicating the new certifying manufacturer. Honda will no longer assume any responsibility as the certifying manufacturer.

• The Honda Distributor's Limited Warranty does not extend to parts affected or damaged by the conversion to or use of fuel other than the fuel for which the engine was originally designed.


• Honda offers V-twin engines specifically designed and certified for use in LP/NG applications. The engines incorporate special design features that address the higher combustion temperatures and reduced lubrication to the valve guide area (since it is a dry fuel, not liquid). Please contact your sales representative or distributor for additional information.


Disclaimer: The guidance provided is intended for Honda dealer/distributor informational purposes only and not for the purpose of providing legal advice. You must contact the appropriate certifying agencies if you require information on how regulations apply to your specific application.

The regulations and additional information can be found at these web sites:

EPA - EPA

CARB - CARB


The run times will always vary based on the actual load put on the generator.

Last year I purchased a Briggs and Stratton 7000w generator. I want to know, is there a natural gas conversion kit I can purchase for this generator?
Donald Gaddis 
from New York 
August 31, 2013
Answer
Thank you for your interest in Electric Generators Direct!

At this time Briggs & Stratton does not offer a natural gas conversion for their portable generators. The units are designed only for use with gasoline which burns at approximately half of the temperature of natural gas.

This type of conversion may severely affect the performance of the unit as the units cannot handle the increased temperatures. Your warranty coverage will be voided should this modification be performed.

Do you have the dimensions of the box as it is shipped?
Greg 
from Connecticut 
August 25, 2013
Answer
Box dimensions are:

L: 35"
W: 22.5"
H: 26.25"

That is the box dimensions only. These units ship on a pallet via common carrier semi-truck and lift gate service is recommended. Without lift gate service you will need to have the means to remove the unit from the back of the semi-truck with either a forklift of ship it to a dock.

Subject: 30470 Briggs & Stratton Generator Hi Jim, If the battery had not been charged previously with the Float Charger can the recoil/pull start be used instead? On your website it says that this model comes with Free Lift Gate service. Does this mean that it could be put on our driveway or in our garage for free? Thanks. Terry
Terry Fudin 
from Connecticut 
June 08, 2012
Answer
If the battery is dead then you can definitely use the recoil to start the unit. The battery/electric start is a convenience and not necessarily required.

Lift gate service allows the semi-truck driver to get the unit off the back of the truck for curbside/end of driveway delivery.

Hi; I purchased the B&S 30471 which is rated at 8000-1000 watts. I am now looking into the transfer panels and outdoor connections. Here is my question. I am looking at the 10 circuit panel but it is rated at max 7500 watts. I know that I will probably never be near max but is the recommended one capable for this gen if it (God forbid) goes near max?
Bob Martin 
from New York 
February 13, 2011
Answer
The recommended manual transfer switches are 30A switches and are perfect for connection to a 8000 watt generator. Generator sizing should be based on 80% of the generators running capacity so the generator has the flexibility to handle the surges without losing proper voltage.

There is another way to give total panel control by using a manual transfer panel which would match your current panel size and is mounted between your meter and your main panel. You can then control all of your breakers as long as you do not exceed 80% of the generators running capacity.

Would the Elite 30242/30470 generator work well with an RV? I'm a little concerned about the noise level since B&S doesn't publish the decibel ratings for their generators.
Ron Heflin 
from Texas 
February 13, 2011
Answer
As you know, the 30424 unit has been replaced by the B&S 30470 and is a good quality replacement with all the new features. This will work with your RV, however, manufacturers are not required to provide db(A) rating as there are no requirements or regulations for this. Briggs does do a good job with using noise suppressing mufflers to keep the unit at decent levels but this will not meet National park noise restrictions as these are designed for residential use.

Sometimes it is better to go with a true RV generator such as the Generac RV line that we carry and can be fueled from your RV gas tank or a separate LP style tank. These units are typically mounted in convenient locations on the RV's. This may be a good option for long term use.

What do I need to consider when running a computer or LCD television off of my portable generator? I currently have a 10hp Briggs and Stratton powered Craftsman generator.
Virgil Litterell 
from Oklahoma 
February 07, 2011
Answer
The main thing to consider is the entire load you are connecting to your generator. The rule of thumb is to size the generator to 80% of the running capacity of the generator so that it has enough flexibility when a large load kicks on (refrigerator) the generator has enough power to handle it and not have to struggle which keeps the ability to output good voltage. It is the voltage drops that can damage/hurt sensitive electronics so it is important to not overload the generators.

Hi Jim: considering the B&S 7000 electric start portable generator but want to know what the operating DB level is. I didn't see it in the specs.
Dale

Answer
Thank you for your inquiry. Unfortunately, Briggs & Stratton, like many other generator manufacturers, do not publish the decibel ratings for their generators. This unit does come equipped with a Low Tone Muffler for Quiet Operation but, I don’t have a decibel number to give you. Currently, there are no industry standards or requirements for generator manufacturers to follow when testing their generators for noise. Due to this, manufacturers can test the noise level under any conditions they choose and, therefore, the results are not very reliable as each company will test under conditions that are favorable to their products.

How many watts do I need to run my heating system in a power outage. I have a forced hot water heating system? I've been reading the specs on the Briggs & Stratton Elite 30470. Is this big enough?
Helen Moe 
from Massachusetts 
January 23, 2011
Answer
Proper sizing of the generator is crucial to the success of any installation and requires a good working knowledge of electricity and its characteristics, as well as the varying requirements of the electrical equipment comprising the load. When analyzing the electrical load, consult the manufacturer’s nameplate on each major appliance or piece of equipment to determine its starting and running requirements in terms of watts, amps and voltage. When choosing the generator output select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 8 kilowatts, select a 10 kW generator). A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future.

We recommend that you have a certified electrician do your wattage calculations to verify the generator size is correct for your application.

Can you explain the benefits of the different alternator types? (Brushed vs. Brushless)
Lee 
from Maine 
January 21, 2011
Answer
Brushless Alternators Benefits:
• Less required maintenance due to absence of brushes
• High efficiency, no voltage drop across brushes
• Higher speed range - no mechanical limitation imposed by brushes/commutator
• Low electric noise generation

Brushless Alternators Cons:
• Higher cost of construction
• Control is complex and expensive


Brushed Alternator Benefits:
• Two wire control
• Replaceable brushes for extended life
• Low cost of construction
• No controller is required for fixed speeds
• Operates in extreme environments due to lack of electronics

Brushed Alternator Cons:
• Periodic maintenance is required
• Speed/torque is moderately flat. At higher speeds, brush friction increases, thus reducing useful torque
• Poor heat dissipation due to internal rotor construction
• Higher rotor inertia which limits the dynamic characteristics
• Lower speed range due to mechanical limitations on the brushes
• Brush Arcing will generate noise which could cause EMI (Electromagnetic Interference)

I'm considering ordering the Briggs & Stratton 30470 - 7000 Watt Electric Start Portable Generator. The only thing I need to know is this- How many hour of power will I get on a full tank while burning 6,000 watts all the way through?
Fred Forino 
from New York 
January 17, 2011
Answer
Briggs & Stratton does not give an exact run time as the listed 50% load run time is an estimate. This is due to the different fuels, personal maintenance and storage which can vary the run time. Also, it is recommended to size a generator to 80% of the running capacity, which helps with the longevity and the voltage output by keeping the alternator stress low. When operating "beyond" the recommended 80% and a large load spike hits the unit, such as a refrigerator compressor kicking on, the unit can struggle with the voltage output and drop below recommended levels.

If your need is a constant 6,000 watts, then you should be looking at a 7,500 watt or larger generator. Emergency

How does this generator start in cold weather with the electric start? What is the difference between OHV engine & Generac's OHVI engine?
Daryl Hammond 
from Ohio 
January 17, 2011
Answer
Portable generators are normally stored inside and the B&S 30471 comes with a float style battery charger which is plugged into the generator when not in use. This allows the generator battery to have a sufficient charge when the generator is needed to start.

An OHV (Overhead Valve) engine is compact designed and generally makes the unit operate quieter. The Generac OHVI (Overhead Valve Industrial) engine is built robustly with premium power and high performance and comes with a fully pressurized oil lubrication system and spin-on filter.
