24v dc from 12v dc

[REBrueckner]

For those who may be adding a modest 24v dc load to a 12volt dc environment Yandina has a slick combiner, the "trollbirdge" which provides 24 volts from a pair of 12 volt batteries...The Trollbridge24 is suitable for installations with alternators up to 100 amps and 24 volt trolling motors up to 85 amps. .....no new battery charge and no new 24 volt battery bank is needed....http://www.yandina.com/

And if a bigger model becomes available it could be used for a higher power
24v dc bow or stern thruster: you may want to let them know if you want such a device.

I recently wrote them as follows:

"Yandina:
Food for thought:

I "met" you some years ago via TWL and was just visiting your website to see "what's new".
I just sold my Hatteras and the new owner had a Vetus bow thruster installed...24 volt, so they also installed a 24 volt battery and 24 volt charger as the boat is all 12 volt....

Looking at your Trollbridge combiner made me realize if that if a higher power model was developed, a 24 volt bow thruster installation could use it instead of an entire 24v battery bank and charger installation......a lot easier to use existing 12volt battes and chargers with a "beefed up" trollbridge combiner."

and I received the following reply:

"Thanks Rob,
We do have the design done on paper for a 250 amp version. It was in response to the need for charging 24 volt batteries to run hydraulics on automobile hauling trailers where the tow vehicles are always 12 volts. The volume so far seems fairly low so although parts were ordered for a prototype, that is as far as it got.

And for those interested, an easy test procedure for shore power cord ground and leakage/electrolysis may be found at

(I have no commercial connection of any kind with these folks; they have been helpful and responsive to my few inquiries and to others on TWL over the years.)

I have to applaud Rob. no longer a Hatt owner, yet still offering thoughtful and insightful comments. I wonder if the device is simply a temporary contact(ing) of the appropriate + & - terminals via 12v solenoid and inductance(?). I will email yandia about that, I would love to have one.
thanks Rob

yes it is.....

and of course it means a 32 volt version is possible....but owners would have to provide information on how they would use it...so power requirements can be determined....
