2 cents worth. Boost/buck boost configuration converters use to increase the PV voltage are only about 80 to 85 % efficient. -- Frank Lewon BZ Products INC. 8801 Gravois Rd. St. Louis MO 63123 USA ___ List sponsored by Home Power magazine List Addres

I should have included that the two Arco modules wired in series are M 51 model, and they have 35 cells each. I had to wolf my lunch and go out and count the cells, you'd think I could remember, I've had these modules a long time, probably bought them from Dave. Lance On Jun 4, 2013, at 11:59 AM

Mac, I'm not much of a poster, but there is another answer. Although I largely agree with the answers you've gotten, as far as they go, but I use a boost M PPT controller from http://genasun.com to trickle charge my 36 V Elek track from a pair of Arco modules. It's not adjustable but is marine g

Mac, No way to do this effectively. You need at least 72 cells to effectively charge a 24V battery, especially during hot weather. Bob-O On Jun 4, 2013, at 8:04 AM, Mac Lewis wrote: Hello wrenches, Is there a good method to charge 24V battery bank with single 60 cell modules? Ideally, I'd lik

Hello wrenches, Is there a good method to charge 24V battery bank with single 60 cell modules? Ideally, I'd like to charge a 24 V bank with a Kyocera 245GX-LFB. However, at NOTC the Vmp is 26.8V. Any good way to do this? Thanks in advance. -- Mac Lewis * "Yo solo sé que no sé nada." -Sóc
