    Hi,

    Off to the continent for 2 - 3 weeks, and I may have to used my Aldi 850W Genny in anger(not literally :Cool:).

    If we put aside the issue of noise pollution, as I would not use on a crowd area or early morning \ late evening.

    I am concerned that such is the cheap and cheerfulness of the genny, the ac genny will spike and knacker my ehu and connected appliances.

    So the options are:

    AC

    • ensure the genny is warmed up and just connect as usual and the ehu should be ok?
    • connect to the ehu and place an in line surge protector?
    • connect and bypass the ehu and place an in line surge protector.Dont use for AC as it will damage your appliances even if you put an in line surge protector
    I guess I should buy a quality surge protector. Any recommendations?


    DC

    • Use to charge the leisure battery. I have not looked at the spec for what current it provides at DC. But will this cut the mustard or I guess anything is better than nothing.
    I be interested to hear if other people have this type of genny, and how it performs. I recall the noise is around 65 dBA which is the low end of a noisy radio(65 - 75 dBA). Also how do you use it for AC \ DC or both?

    You are in a lose lose lose situation.

    A good surge limiter costs loads.

    If it spikes your electrics this costs loads.

    If you use the 12V out it's only a low amperage (100W seem the norm) unregulated output and so you'd need to monitor the battery voltage manually.

    Here is a bit of common sense:

    I am mindful of the saying buy cheap, buy twice. In this case buy cheap, buy new EHU :Eeek:

    The $64k question is will my Genny produce x number of spikes\surges during operation to override a surge protector? I have read posts where people have come a cropper i.e blown ehu, laptop. Equally, there seems to be opinion that it is not really a problem?

    I am of a mind to bypass the EHU and use the TV\DVD generally low wattage devices. My thinking not drive the genny to hard will minimize the size and frequency of any spikes.

    The DC, yeh agree the charging voltage is important and should be staged to maximise the charge and the life of the battery.

    Any one used the Aldi or equivalent genny on AC or DC Charging?

    Thanks for reply and the link.

    Dave

    I don't think anyone can answer that, that is the nature of a spike. It might only happen when you run out of fuel or get a bit of dirt in there and it stutters. Impossible to measure.

    Inverter generators are much cheaper than the equipment you are powering with them.

    I've got one of these but with a different name and cheaper, so far little use but no damage.

    Your genny may be perfectly OK but can you risk it ?

    Yeh, absoloutely agree re: the spikes. No one is going to tell me if it spikes x no. times etc. But it would be interesting to see if people are using this type of genny with or without protection.

    I got the genny before I had the Motorhome, just made sense to move it form the shed to the MH. I did consider purchasing a inverter genny. But wasnt sure how often I use it...well until now.

    Hi,

    We purchased a cheap generator several years ago similar to the Aldi unit, and have now left it at home, as we only used it twice, and that was direct cable through the window so the wife could use her hairdryer, which I will add worked perfectly, as for the lights etc we never really stopped anywhere long enough for the leisure battery to go flat max 2 days and then moved on and the engine charged the batteries.

    hope that helps,

    It supports the case of the cheap gennys for MH use. Howvever, it be a brave man who connected direct to the EHU unprotected. But like you infrequent and short use seems relatively risk free.

    Thanks for the reply.

    All this talk about spikes and unstable voltage :Eeek:

    Can anyone tell me what damage they have suffered as a direct result of using a cheap genny to power their motorhome??:thumb:

    A few months ago we had a nasty power cut, mains flashed off and on a few times - it killed my Schaudt charger. Others have had similar experiences so we are right to be cautious.

    I don't recall the circumstances of the other deaths.

    So it would seem so far that using the mains is more likley to cause a problem:Doh::Doh::Doh:

    What it does mean is that some electronics are far from robust, but that's what we are prepared to pay for.

    Since most "things" are plugged into mains then most failures will be on mains.

    I have read about gennies causing failures but a good while ago and the details are gone now so I did not say this until under severe cross examination.

    Bottom line it's your kit how much risk are you going to take ?

    a cheap, unregulated genny wont do any damage to the hookup, wiring or fuse box.

    but........if you have a digital/electronic control panel it COULD be damaged in the event of a power surge/spike.

    same goes for anything voltage sensitive plugged into the 240v sockets including the onboard charger.

    i had a cheapo 850w jobby in the garage that wouldnt behave when running power tools.....tools running slowly.

    checked the output and no idea why but the only way to get 230v from it was to increase the engine speed from 3000rpm to around 5000rpm......great, 230v BUT at 85hz....not 50hz :Eeek:

    If you have a Schaudt EBL or I suppose any control panel that you want to protect from mains problems, I would advise buying one of their OV-1 voltage protectors. They also have an extra output that you could use for sensitive equipment that you also wish to protect.

    Sorry to double post, but I think this thread should be renamed to 'Cheap and Nasty' as I don't know anything cheerfol about a 75db 2 stroke genny.

    cheap cheerful and last chance backup system use with a 240V proper battery charger and only to recharge in an emergancy situation, failing that just call out your recovery service and save the weight.

    So it would seem no-one has had a single issue using a cheap and cheerful genny with their motorhome then??:Wink:

    All the doom and gloom merchants sit up and take notice :Eeek:

    Yes it COULD happen and yes if the circumstances are just right you MIGHT damage something, MAYBE.:Doh:

    Personally ive been using cheap genny for years for both work and play. Ive ran all sorts off them from TVs to laptops to power tools and everything in between. Never, NOT ONCE in all that time have i ever had a problem even when the things run out of fuel and all the rough running and coughing and farting they do just before they die has there ever been a problem.:thumb:

    The choice is yours but the simple fact is not a single person reading this has ever personally had a problem with damage caused by a cheapo genny.:Blush:

    The noise is another issue however:cry:
