Arghh I can't find anything on 64 volt solar panels and how to wire them to a boat. Anyone know anything about this or have any advice? Also I was thinking of using a voltage reg would this work or just burn up the regulator? Any help would be greatly appreciated i've been searching for days now can't find anything.

You do need a voltage regulator unless your power output way exceeds the input (but its still good practice to have a regulator no matter what). Just make sure its a regulator capable of handling the wattage. Other than that, its a pretty straight forward install.. Solar panel plugs into the regulator, regulator connects to the battery.. Red to red, black to black.
Wow, I need to learn to read. I thought he said 64 watt, not volt.. Unless he meant to say 64 watt.
Some regulators
Seems to me I have seen some regulators that are rated for higher voltages. What are you doing and where did you get panels that are 64 volts. The regulator would have to be able to handle the voltage, and the amps.

Im gonna use it mainly to recharge batteries while cruising. The panels my sister bought for 75 bucks each of the internet. Wow so pretty much a voltage reg would do the trick with a 2 battery setup there is nothing special about the 64 volts it seems just more output? Thanks guys for the replies this helps my understanding greatly!
Im sure its 64 volts and I only have one panel with a 2 battery bank. Maybe ill try and contact the guy around here and see what he says. I really would hate to fry my batteries lol but who wouldn't?
Can you provide a link to any specs for these panels?
There might be a way to break and reconnect the individual solar cell connections to provide a lower voltage at higher currents.
Otherwise, yes you could use a regulator and use the panel as-is, if the regulator can tolerate such a high input voltage, but because of the huge voltage mismatch, you're only going to get about 10 to 15% of the potential energy the panel is capable of delivering in a more efficient match-up.
in my 70+ years, I have never HEARD of anything using 64 volts!! Never seen a 64 volt anything, 12, yes, 24, yes, even once a 48, but I don't know how you'd get 64 volts.
One panel with a two battery bank equals either 12 or 24 volts MAX.
I suspect he's talking watts. And for a really good company for solar controllers, try Morningstar- http://www.solar-electric.com/mochco.html

Here is some info about high voltage solar panels:

I have never seen them used on a boat, but with the right controller they should work.

I don't recall ever seeing a 64V panel but perhaps they were specifically built for some odd purpose other than standard use?
In order to get the most out of these panels you will need an MPPT controller that can handled both the wattage and the current. If you use a standard PWM controller you'll throw away a lot of potential charge current using a 64V panel to charge batteries at around 14V... The MPPT will convert as much excess voltage to current as it can but at PWM or shunting controller won't..
Can you please take a photo of the panels rating plate, write down the exact specs or give us a brand to work with? A 64V panel would be a real oddity...

NO Problem. As was said, just make sure to use an MPPT controller and you will save a bit on the size of wire you need.
