Solar Panels


G'day all,

We recently acquired two 80watt portable panels to feed a 120A/H AGM battery. A couple of weeks ago we returned from a trip where we spent 10 days free camping in order to really see how long we could be without mains power. Three of those days were without TV, (no service available) but we did view dvd's on a couple of occasions. The panels took around four hours to top up the battery, on cloudless sunny days.

The better half has suggested that it would be nice to be able to use the Microwave occasionally. My question is this, If we install an inverter to drive the 800w M/W to heat up food, soup etc; would this put too much drain the battery. The views of those in the know would be much appreciated. I have always had problems trying to work out how many amps or watts are used!!!!.

Regards,

Phil B.

Hi Phil

Forget about an any form of heating from solar unless you have LARGE battery capacity& a LARGE solar panel set upno

Your,s is a asmall setup

A 800W microwave will  draw abot 1600W

1600 Watts @ 12v =133A

Half an hour operation & your battery will need to be recharged

The inverter would need to be around 2000W

Forget the microwave, I think you would need a very large invertor ( I would think a min of 2000w) and then more battery capicty.

All the extra battery/solar/inverter capacity needed would make it a very expensive microwave.

I run 2x300w panels charging 2x100ah batteries and a 1000w inverter and it wont even look at the microwave. wouldnt waste your time messing with it, if you really want the microwave get a generator and then you can also run a/c if you get the right gen. I have a Kypo 2600 and that will run the a/c or microwave but not both at once.

We just recently purchased a 3000w sinewave inverter to run a few small appliances like foxtel,laptop etc.So I got my auto electrician to hook it up,when i came back to pick it up he said to me it runs the microwave brilliantly.I was surprised as I had no intention of running the microwave,have not done a full test yet until I have power to top batteries up in case they drain too much. We run 2 x 120ah gel batteries.Will post when i test them out.

Hi

I assume you are running any of those direct from the Inverter,& that the inverter has not been wired into the van 240V system?

An inverter is reasonably safe used  THAT way with just ONE class 1 appliance [always have a 3pin plug]connected at anytime

Connected more than ONE Class1 by means of power boards /double adapters etc decreases the safety  & under some fault conditions can lead the electric shock & possible death

TAKE CARE

Peter

Thanks to all who replied. I have talked SWMBO out of the M/W I think! Will stick the baked beans in a saucepan I reckon. But, its the old story, if you don't ask you don't find out.

Regards,
