As a couple of others have eluded to, an advantage with the MX60 Outback unit is it's internal buck converter, meaning you can use an array with a voltage up to 72 to charge a battery bank of any voltage, even 12. I have 3 130 watt cells that are wired in series to send a lower amperage (7.5) but higher voltage (52) feed to the MX60, which then converts it back the other way to 12 volts at higher amps. A HUGE advantage of this feature is to allow much smaller wire run from the combiner to the MX60, with lower losses. Copper is outrageously priced right now, so it's a pretty substantial savings for a 35' run.

reveiw of costco .com solar set


I will jump in here. I din't read all the posts here so sorry if this is redundent .
Certainly most of you guys are very experienced with solar , probably having large systems . Any ways all I want to say is that ,after looking around the internet , I found a 60 watt set at costco.com . I have bought two sets so far . One i have set up for our house I'm only running about a 100 or so watts which with the use of cfl 's has our kitchen and living room covered pretty well. About 500 sq. ft. is all. we have had a couple of power outages lately . It is cool to still have lights .
The other set we use when we are in Baja for our 24 ft. trailer. It has been totaly suffecient for our needs . Set it up and forget about it . The best part is I don't have Mrs. Tortuga on my case for running our gen set . Never have liked generators anyways ( feel guilty running one)
So to make a long story short . I would recomend this set to someone who doesn't want to invest lots of money or know much about the solar thing yet. It is all plug and play for $350.00 .
You will need deep cycle batteries . I bought walmarts trolling batts for $50.00 ea. I did find that most of the rv batteries are so called hybrids ( cca s ) etc. The trolling batteries actually are rated in amp hrs. 75 which I know are babies to you big guys but they work fine for our trailer.

Well thanks for your time and I am looking forward to being of grid in Los Barriles some day ( I guess I am already, Dugh!) I would like to check out some of the big systems you guys have down there. Also thanks for not putting more of a strain on their power grid and environment .
Tortuga
P.S. Did not mention earlier but the solar set I am refering to here is the sunforce brand

Walmart A-OK


Right now, I have Five separate arrays and have been using the Walmart Deep-Cycle Trolling batteries on the Four Smaller ones with a total of Eight batteries in use. They are priced good, work well and seem to have a 3-4 year life cycle. No complaints.

Do you think or know if they are using solid lead plates in those things ? They seem heavier than the hybrid I have (interstate rv marine) Thanks Tortuga .
What is cool for me about this subject , is in my mind going to Baja California , is about getting by without power etc . Figuring out how to be selfsuffient while there . This subject speaks to all that . Now for most of us that have second homes there We can help the natural environment by being off grid . That is very exciting to me . As for you guys who are already . Right on ! I suppose also if there is a market for a technology then improvements in that technology will follow . I'll bet you guys who have been around solar for a while have seen improvements over the years . To bad people don't buy p.v. stuff like they buy computers and digital cameras !
Buen Dia , Tortuga

No Se !


I checked the documentation I have and it doesn't specify the Cell composition. A cursory Net search produced negative results on that particular question. I did read on a Bass-Fishing site that they are the Number one selling battery in that class. That might be, of course, simply because Wal-Mart is so big AND they sponsor a Bass-Tournament yearly in the Everstart name.

They do seem to be pretty good, though. I read a lot of comments on the various "Bass" forums and they were all favorable.

If I ever run across the composition answer, I'll let you know.
