These guys have dc to dc converters. IIRC, some are 90%+ efficient. I
have used their stuff in my solar deployment. http://www.solarconverters.com You can buy their stuff at several online solar stores. Jason Randy Cosby wrote: What do you use to convert? The tycon power item Jayson pointed to is only 75% efficient, and only can handle up to 1 amp of load (a little too small for me). http://www.tyconpower.com/products/POE_Inserters.htmAny other solutions?

What do you use to keep your solar "boost" voltage from forcing a shutdown on the Mikrotik? I've used some 24 regulators, but they seem inefficient, and have low voltage disconnects that are sometimes too sensitive - ie: if my battery goes down to 22v, it will shut down completely (yes I know the batteries should never go that low, but I don't live in a perfect world). |
