Quiet Solar System


Hello all,  I will be installing a solar system in my Forest River, lexington210, motorhome.  Of course I will listen to all advice but my concern, because the space I intend to use for batteries and controls will be below the couch/bed.  The use of AGM batteries takes care of the gas venting concerns but I have read that the noise level of the converter and controller could be a problem for our sleeping.  Any comments please.

Ken

Just a guess, but I'm thinking that the only noise source for a converter or controller would be relay or fan noise since most electronic devices today are solid state. Since a relay would only make a noise when it is going on or off I don't see that being a big issue. That leaves the fan, which I could see being somewhat of an issue if you need it really quiet to sleep. If that is the case, there are quiet fans available for not very much money that should solve the problem. However, most fans make white noise which many people use to mask other noises. Here's a source for quiet cooling fans: www.quietpcusa.com/Quiet-Computer-Fans.aspx

If there is something I missed that is making noise there is always acoustic foam insulation. Although it is not as good as elimination of the source, it is better than nothing. Here's a link to an FAQ: www.thefoamfactory.com/acousticfoam/faq.html. The same site also sells the foam.

Additionally, if you want to reduce the transmission of sound through the structure of the coach there are vibration isolators which can be searched for on the Internet.

In short, I don't at all see this being an insurmountable issue for less than $50.00, probably less than $20.00 plus shipping.

Just my couple of cents.

Thanks so much for the reply.  The noise I have read about comes from the inverter fan.  This has been mentioned in the con (pros/cons) comments.

Hi Larry,  How does your system perform in general ?   What do you run with it and for how long?  We are planning a 12 month (+-) x-country adventure in March.  After many months and visits to choose an RV, we decided on a beautiful, pre owned 2005, Forest River, Lexington2210 motorhome.  I will make several mods to the storage and "bathroom" area.  Solar is a big MUST.  We want to be able to dry camp any time we want.

Ken

While I carry a backup inverter generator I haven’t needed it in the last 60 days of camping. I run everything except the microwave and AC including liberal TV...mostly local news which helps me find sites to visit. With a larger solar system I believe microwave use is easily doable. My solar system is never “off,” beginning to charge at sun up and stopping sunset. Do the energy survey and multiply by 1.5 to 2.0. That will set what you need in panels and batteries.
