answer 1
OK, here's the deal. Per the owner's manual you need to run the generator once a week. This process is definitely necessary because not only does it help you evaluate the battery to see if it needs a charge buy it also lubricates the engine internally and moves fuel through the fuel system. This also helps you confirm that the unit will work when your power outage happens which should give you some peace of mind knowing its going to work like it's supposed to.

A recommendation to Generac would be to provide a complete trickle charger or better yet, a float charger so you can keep the unit plugged in all the time to keep the battery charged. Yes, the likely hood of someone actually running the generator once a week will probably drop but that personal maintenance is on them either way. If they have a float charger at least they will have the option to start it with a charged battery instead of having to pull start the unit when you have just lost power.

answer 2
Generac's approach to this whole issue seems silly. If the generator is so good and generates so much power, why can't it spare a little to automatically tricke charge the battery? And when they say to charge it via a regular wall outlet is rather difficult to do during a power outage! 'Sounds like another "Catch 22" for back-up power!

According to customer service, the reason Generac does not recommend charging the battery via one of its own 120v outlets is because commericial power is "cleaner" than generator power. Although it will work as a last resort, they don't recommend it. But if this is a problem for a little battery charger/transformer, then what about everything else in the house?

So my recommended solution is one of the following: Until Generac can supply a battery charger that is recommended to work with their own generator power, either 1) Call your local utility and find out when they plan their next 8-day power outage so you can be prepared, or 2) check and/or charge the battery via commerical power once a week!

Question

Exactly how much oil does the GP7500e need at 1st use?

My unit has been delivered. My question is in regards to how much engine oil is needed.

The instructions state: "Slowly fill engine with oil until the dipstick reads full. Stop filling occasionally to check the level."

The "dipstick" is less than 2" long and has no visible Full marker. Once some oil is added the dipstick is wet with oil.

I am hesitant to test the unit without knowing this. The unit came with a 1 litre bottle of generator oil. I'm assuming it doesn't require the entire 1 litre.
Do you know how much to use? Please advise!!

Thanks,

Question

GP7500E - how to charge battery without a mains supply

On a GP7500E, the manual states that the battery is not automatically re-charged when the generator is running, which means that unless the generator is moved and connected to a mains electric supply, then eventually the battery will becone discharged and the electric start will not work.

Q1 - is that correct?
Q2 - if so, is it a problem to simply hook up the supplied battery charger to one of the 120V outlets on the generator so it charges itself when the generator is running?

Thanks.

You are correct--the battery does not charge when the generator is in use. While we recommend plugging the battery charger into a wall outlet to charge the battery, if you are starting and stopping the unit repeatedly you can plug it into one of the generator's receptacles to make sure the battery has a full charge.

Question

Fuel shut off valve

I just received my generator. Had an electrician hook everything up. When shutting down the generator I closed the fuel valve to shut the engine down. The engine did not shut down. It sputtered but never shut down. Didn't want to damage anything so I ended up shutting it down manually. Does this take a while for the engine to starve itself? Or could the valve not be working correctly? and lastly is this the correct procedure to shutting down the generator.

When you close the gas shut off there is a small amount of gas that remains in the line. The engine will run until the gas line and carb are empty, this is normal. I tell my clients when they're shutting down the generator for the season or what could be a long period of time closing the gas line while the engine is running is a good practice. If your shutting down to fill the gas tank than use the "off" switch.

answer 1
From my own personal experience, with the proper wire size, you can locate the generator 150ft from the transfer panel. In my own appication, the generator is located in my tool shed with the doors propped open (just in case it rains or snows!) A 50ft L14-30R cord connects the generator to the power inlet. From the power inlet to the transfer panel I ran a 6-guage, 3-conductor, grounded "service" cable to minimize the volatage loss.

During my "field test" last week, I measured only 0.1v loss between the 250v generator outlet and my transfer panel--a total distance of 147ft (97ft of #6 guage cable plus the 50ft generator cord)--and the generator carried the load effortlessly.

answer 2
Running synthetic oil in this unit should not be an issue. However, we want to point out that the modification you have made to this unit for gaseous fuel (LP or natural gas) unfortunately renders your warranty null and void. Generac does not recommend such modifications because the unit is only EPA tested and approved for use with gasoline. Because Generac has not conducted any testing on this unit with gaseous fuels, we cannot speak to the performance, life, or safety of the unit as you have modified it. If you have additional questions, we recommend calling our customer support team at 1-888-GENERAC.

All Generac portable generators are bonded neutral, while most manual transfer switches are floating neutral. To work properly, your transfer switch must be a three-pole switch that also switches the neutrals. You may want to contact a Generac dealer to confirm the correct transfer switch, and to set up the wiring to connect the generator.

answer 2
Currently Generac does not manufacture a kit or accessory for removing fuel from the system. To drain the fuel from a portable unit, you can either run the unit until the gas tank is dry, or you can use an automotive style siphon to siphon the gasoline out of the tank through the fill opening. If you plan on siphoning the gasoline out, you will still want to run the unit until it is dry to ensure there is no gasoline left in the carburetor. Any time the unit is not in use, regardless if fuel is present in the fuel tank or not, the fuel shut off valve should be turned to the OFF position during storage.

answer 1
The GP7500 portable generator can cover a wide range of household appliances and items, however the exact items it can cover will vary for each application. The GP7500 generator is rated for a continuous output of 7500 watts, with a rated amperage of 31.2 amps at 240 volts. This rating is when utilizing both the duplex style and the twist lock style receptacles. You will want to ensure that all of the items you intend to run will not exceed this rating. We recommend working with your local certified dealer or local electrician to determine the best generator for your needs.

Without knowing your home that is impossible to answer. On average this unit will take care of your refergerator, a TV, sump pump and probably your heat but it is impossible to know for sure. The math is (watts) divided by (voltage-either 120 or 220) = Amps For example: 100 Watt bulb (divided by) 120 Volts = Approx 1 Amp. So generally speaking a 7,500 watt generator can light about 75, 100 watt light bulbs.

Question

Battery charger

I have a GP 7500. I tried to charge my battery after found I couldn't start it. with electric start. Charged it overnight and some and still couldn't start it electrically. My neighbor has a small battery charge and connected it to the battery and it started right up. Is it possible I'm doing something wrond or do I possibly have a non working charger? My generator is 1 year old with not even 200 hrs on it.

The charger provided with the unit is intended to be utilized once a month for 24 to 48 hours to ensure optimal battery performance. If the battery has not been recharged periodically as described above, it may be dead. A dead battery will not accept a charge and will need to be replaced.

You could have a bad charger, but I would suggest trying a different outlet first, and also make sure the plug is all the way into the generator. Take a look at the plug end too, where the wires are molded into the plug, if someone yanked the plug out or tripped on it, there may be damage.
We hope you make out ok, we know the storm was worse down there. Thankfully the generator has a pull start too!
