Current LD Charge Controller or Recommended Brand March 31, 2012, 10:29:45 am Yahoo Message Number: 129543Hi All Hard to believe there are nearly 130K posts. (I remember when there were 4K) But to the question. My 2002RK still has the RV-30S controller in it and while I am religious about adding water the batteries the volume of water used means they're baking and the culprit is the charge controller. So after 10 years of this I would like to replace the battery killer. Net is with what? No more HPV-22B's are available so what is everyone using now? I have done a few searches but even up to last December the talk was of the HPV-22B. So what are people/LD using now?Thanks in advance for the info.Gary

Be careful here - one sign of internal battery problems is rapid water loss with a normal charge voltage. A common issue is a shorted cell, which will place too much charge voltage across across the remaining 5 cells. If you find you add little water to one cell, but a lot to the others, this is an indicator. Also, disconnect the batteries for a couple hours, then compare their voltages.Steve

When adding water I notice one cell was lower than the others. Took a lot of water. Then when hooked up aga

Re: Current LD Charge Controller or Recommended Brand Reply #9 – April 01, 2012, 08:24:31 am Yahoo Message Number: 129566I would look at a Morningstar Sunsaver MPPT 15. If you already have a battery monitor like a LinkLite, the sunsaver mppt 15 could be all you need. If you need/want a digital readout, you can add the Morningstar RM-1. Unless you mount the charge controller very close to the batteries, consider adding the remote temp sensor. I see both on the AM Solar website, and they are commonly available from a number of sellers. You're looking at $250-$400 plus install, depending on which options you choose.Rich '03 MB

I use that model, which is a very sophisticated and well-made design. I like it because it is small, can be hidden, and does not need a cutout in any panels, if you do not need the optional readout. Its mounting does have air circulation requirements, but I have never noticed any heat from ours. It has a maximum rating of 200W of solar input, 15A output. It is protected against over-driving, so 170W will be no problem. I am planning to shortly upgrade to 200W solar, from our current 106W, and am anticipating no issues. Although I have no solar readout, I do have a LinkLite battery monitor, which is the more useful tool if you want to minimize read-out clutter.Steve

You do bring up a good point that I didn't make clear. Don't mount your charge controller _IN_ the battery compartment.Rich '03MB
