Question about Coleman Powermate Premium Plus 6250W Portable Generator

1 Answer

Propane-converted generator sometimes sputters out and dies

Hello, my neighbor has a propane converted Coleman generator to charge his off-grid solar batteries during cloudy weather. It always starts ok, and runs great for about 15 to 20 minutes. Then suddenly the motor stumbles and drops in RPM. Sometimes the motor then dies, other times it catches back on and continues to run good. Whenever it dies, it always restarts with no problem, even immediately after it dies, so perhaps it is not a fuel-delivery problem. The time of running to when this problem happens is never exactly the same, sometimes happening a minute after it starts running, or it might run great for 20 minutes before it dies, or it might stumble and then catch on again, continuing to run for 5 more minutes. He doesn't have an owner's manual, so I don't know where/how to check the ignition components. I've wiggled all the external wiring while it's running, but that doesn't make it die. Any suggestions/help would be appreciated.

Solar panels not clear

it is a calcium build up
get a liquid cleaner that removes calcium and scrub it on the panels
just a side note here
I used to worry about the problem as it was affecting all of my garden solar lights until I bought a small solar panel from JAYCAR and placed it well up in the air and away from any spraying water
to my dismay it also went white but it still charges the battery enough to run solar lights all night to next morning
I think that the panel works from ultra violet rays that penetrate the white film so making the panel parts work
for roof panels that charge to the utility grid, the loss from dust and bird droppings is less that 1% so these companies that charge big dollars to clean the panels are in fact close to rip off people get more information by googling for sites that have cleaners to assist you

I am getting an older 8HP Coleman generator 4000 watts output. . My proposed solution is to install isolated outlets directly from the generator output to certain areas in the home.

You need to consult a local electrician, if you do this wrong you can cause allot of damage. We can only guess as to the correct way to do this without being there and looking at the wiring setup.

Is this true or scam Government pays you to go solar.

The US government WILL NOT PAY you to go solar. There have been incentives on the state level to get people to install solar panels. Most of these have dried up but it is possible to find programs that will reimburse you a portion of the total cost but don't expect much. We live in Florida and in 2009 we were promised nearly 1/2 back if we installed. We got less than 10% when all was said and done and it took 2 years to get that.

I have solar panels that put out a little more voltage then they are rated at,and they keep faulting out my grid tie inverter.I need a resister to knock down the voltage about 8 volts, got any ideas?

I like to ask, is the voltage from the solar panel messure with some load connected or is open circuit, normally solar panels produce high voltage than the working system, the reasson for that is to have Amperes in of to charge the batery, these is related to the size and power generated by the panel.
No need a resistor or in any case use a voltage regulator to prevent over charge.

How do i convert my 1.2kw solar inverter on my roof so i can run my home on stored energy ?

Solar panels produce DC voltage.
some solar panels have the inverter integrated into each solar panel.
I would suggest contacting a local solar panel supplier and asking them if they could add a Battery Charging System to the Solar panels you use. An then what sort of inverter to add to the bank of batteries.
An inverter converts DC voltage to AC voltage to use in the grid.
The AC voltages and DC voltages involved have the possiblity to kill if you much around with electricity.

I am looking for an owners manual for a Coleman Powermate generator model PMO645250

Powermate doesn't have an owners manual listed for the PM0645250 on their website.

Since wintertime is a good candidate for power failures I would recommend using a good synthetic 5w-30 oil as it is a good year around oil. This would make starting much easier during the cold weather

Generator w/nat gas conversion kit sputters

THAT SOUNDS like a VERY LEAN condition. The exhause glowing is because its so lean. The stalling the sputtering. OPEN the gas valve more WHILE its running. With a load if possible.. If you have a tri fuel kit like I do, going from propane to nat gas I need to open the load block (gas valve) 2 turns more .Then it starts and runs great.

I have a coleman model 525202 with a 10 hp tecumseh when idling it pops and runs bad but as soon as i put a load on it it smooths out i have replaced the plug gap is at 30 changed fuel and air filter...

Hello; Make sure all the moving parts on the carb are free especially the governor shaft going into the front of the engine.Use Gumout or PB Blaster to free up parts. Then start it up with no load. Turn the needle valve on the bottom of the carb counterclockwise until it starts to sputter out. mark this point in your mind and then turn valve in clockwise. Engine will smooth and then start to die. Back needle off to a point halfway between these points. If it is way off turn in carefully till it seats, then back out 1 1/2 turn to get it to start.You may still have to do a touch up when you put it under load. John

You can try insulating your battery (cold might still get thru) or purchasing a solar recharge kit from an aftermarket company. Cold weather will affect the chemical reaction between the plates of the battery and will not put out the high amperage required. I would also recommend to keep a portable battery booster in case you cant get a solar charger. Keep the booster in a warm bag inside your trunk and always charged for when this happens. Keep it during the duration of your winter weather. In summer you will be fine.
