Would like to know if you can charge 6 volt batteries in my RV and if the panel has a auto shut of when it reaches it peak

"No" to both. If you have two 6V batteries and hook them up in series, the panel will work. This is a "battery maintainer" and has no sophisticated electronics other than a diode to prevent reverse flow/battery drain at night.

No. Just hook it up directly to the 12volt battery posts. I have owned mine for some time now and it works very well to keep my RV auxilliary battery charged.

It's a pwm controller so it works in stages it doesn't overcharge my battery. I think its sable at 13.6 volts when it shuts down to charged mode. I only use it when im camping so I can't be sure. But it works great with 2 100 watt panels.

I Charge 2 6V 200 Ah batteries in series with this charger. I have also charged them individually - Doesn't seem to make much difference in charge time. Short answer - Yes. (Of course you would want to disconnect your PV array/charge controller before connecting this unit)

I would believe the instructions! Keep the + and - of the panels isolated from your trailer ground. The charge controller to batt should go directly to + and - terminals of batt ( + should go thru a 30A fuse! ).

I use this panel to charge a 4ah lithium iron phosphate battery w/ a charge controller to regulate voltage(14.1). I wanted an unbreakable portable panel for charging electronic devices. You could link two of these in parallel to 2 group 24 batteries but it would only be a trickle charge(&lt;20watts). I would suggest a cheap charge controller even though it's not necessary to extend your battery life. These are nice panels but for two 85ah batteries you might aim for 50-75watts.

I charge 2 6v lead-acid batteries (in series) with it for RV - have had no trouble. This link gives the various charge rates and protections. Not sure how the controller would handle 1 bad battery of 3 wired parallel. http://www.directdepot.net/manuals/Go_Power_MAN_GP-PSK_80.pdf

You won't want to connect the panel directly to a battery, as it could damage or overcharge it. The panel itself only provides a voltage, you need a charge controller between the panel and the battery. The one I used (http://www.amazon.com/gp/product/B001HWQZNQ/ref=wms_ohs_product?ie=UTF8&psc;=1) is not currently available, but should give you an idea of what to look for. You want a controller that can handle at least 30 watts and 17.5 volts input for charging 12v batteries.

No, it is a stand alone system. You would need to buy an inverter/charger combination same as is found in RV's.

Yes! It won't be overcharge on my home energy at 24hr 7d week all year round. It will be safe to charge with solar panel. It only charge on day time and night time none. As long it's a twelve volt charger to charge these batteries.

yes that is what I do in my boat for 2 rv batteries and it works great. make sure and get the power regulator so you don't over charge your batteries.

It does not shut off automatically, and I'm not sure why you would want it to. I guess you could cover the panel from the sun if you wanted to, or disconnect the battery terminals.

I think that the voltage is about 15 volts. I leave mine charging my RV battery andhave no problem with it. It stays charging for months at a time.

If the rv is a 12 volt system then yes. The batteries would be connected in a parallel configuration .you can tell if this is correct by looking at the battery terminals. If the positive+ is connected from one battery to the + of the other battery then the system is most likely a 12v system. But if the + of one battery is connected to the - of the other battery the batteries are connected in series making the system 24v in that case the charger could only charge one battery at a time

This is a good solar panel. I have 2 batteries connected parallel, + to +, and - to -. This gives me the same voltage- 12 volts. I run my garage door opener and some accessories in my garage off a power inverter. The Ramsond solar charge regulator shuts off when batteries are full. Like T.J. said, make sure you aim the panel for best results, and hopefully its not foggy where you keep your boat!

These connect to the supplied (or a replacement) charge controller which connects thru a fuse to your battery. If your generator also charges the battery then this charge controller simply will be over shadowed by the generators charger (as in at night). I have it connected this way and it works fine. (Both chargers in parallel with no issues.) I'm keeping this charge controller as a spare and have replaced it in my RV with http://www.midnitesolar.com/pdfs/spec_sheet_kid_frontBack.pdf. I ended up getting a total of 4 of these panels for a 400W system. The Kid essentially adds another virtual panel due to it's improved efficiency.

Yes. I disconnect the battery from my camper 'load' during the day, allowing the battery to charge, then switch back to battery in the evening. Just requires in-line switch for 'load' side of controller to camper and in-line switch from battery to camper. Has been working quite well.
