    Default Advise on Generator & Inverter combo

    I was wondering if the guru's on this board could help me out.

    I currently have a 2.5 k inverter running on 4 x 12volt batteries. But as many of you know the blackouts seem to be coming back. And the amount of electricity that the inverter gets is sometimes not enough to recharge the batteries. So I'm debating on getting a generator to back-up the inverter.
    These are my options:

    A Coleman Maxa Powermate 5000 watt with a 10hp motor. The price is $399

    or

    A Coleman Mega Pulse 1850 watt. The price is $299

    Will the smaller unit be sufficent to recharge the batteries?
    Are these prices a good deal?
    Or should I pay the extra $100 and get the 5000 watt unit?
    Does anyone have experience with Coleman generators?

    Speed is of the essense since these are sale prices and I don't think they will last for more than a day or two?

    The price on that 5000 watt unit is good if you ask me and Coleman is a very good name in Canada.

    This guy says MORE POWER IS MORE BETTER!

    Default I think you should e-mail me

    Since you are in Santiago, I do think you chould send me an email. There are some good solutions to your problem.

    As the man said, more is better, but stay away from gasoline engines.

    Depending on what you want to run in your house, and the quality of life you expect, you need to look closely at your options.

    Default Main question would be.......

    I know it's best to have more power available but, will the 5000 watt unit be over-kill. I am planning on purchasing 4 more batteries so that I can connect my friegh to the inverter. And my last 4 monthly electric bills have been in the range of $700 pesos so we don't use too much energy.

    I could use the extra $100 for something else but if it's worth it I will buy the bigger unit.

    Default Um... I have a coleman 7.5 kilo

    And it is nearly useless for inverter combo use. It does not output power of sufficient quality to charge batteries, (most inverters require a high quality waveform for charging since they only use the peaks) and it is deafeningly loud even from a reasonable distance. Additionally, the potentially long runtimes for backup purposes are very damaging and I have had to have major repairs done on it several times. (even though I have never run it for longer than 6 hours at a time - or 1 tank of gas)

    Please do yourself a favor and get a small diesel generator, then immediately start looking for someone to contract for regular maintenance checks.

    From what I understand from previous posts, these Coleman units are pieces of junk for our usage. They are designed for occasional use when camping.
    If my 2900 watt Honda generator cost $850 US, what does that tell you about the Coleman unit that has 60% more power at less than half the price?
    JUNK...
    Although I agree that diesel generators are better units and more economical to run, I agree with you that a small gas generator will do the job for you.
    Diesel generators are a lot more expensive to buy.
    If you were planning to run it everyday, then it would be a different story.
    Those few rare times when I have run my batteries down, do not justify the additional expense of buying diesel, and I do manage to charge my batteries up, with my small semi-quiet Honda.
    PS: You may want to try buying 4 additional batteries, before going the planta route, and make sure your charger control is set to it's highest position.
    PPS: Is your inverter a Trace/Xantrex?

    I have until Oct. 2 for the sale. So all the input you guys can give is well appreciated.

    I went back and the correct unit is a Coleman Maxa 5000 ER Plus Powermate.

    I checked a few spots online and it was going for over $600...so it seems like a good buy.

    Well you got my input - don't buy a Coleman unless you want to end up selling it on the used market and looking for something better.

    I am about 75% sure that Coleman does not have any manufacturing or engineering facilities, I think they just re-brand other people's factory seconds and designs they didn't feel were good enough to represent their own brands, kind of like Radio Shack.

    I have also heard that the Coleman units work much as boat anchors and are a complete waste of time and money in the DR.

    Like Rocky say's, nice for camping...

    Default Thanks for the advise

    I think I'll hold off until something else presents itself.

    Let's just hope the power situation doesn't get any worse or I might just have to buy the coleman.
