- Makes a reliable regulator but it really lacks in the options & programming area. They also do not answer phones and only do tech support via an on-line forum. I stopped using them a while ago due to the lack of support and lack of programming options. Still, they build a reliable regulator
- Just google Xantrex tech support....
The Xantrex XAR regulator is made by Balmar for Xantrex, enough said... Why buy Xantrex when you can buy the Balmar and get Balmar support?
- IMHO the best support in the industry. Dale, Tom, Rick & Rich are always available and bend over backwards to help. The Balmar regs are very programmable to do what ever you need or want.
Your Bosch alt is likely internally temp compensated via the voltage regulator. Some Hitachi's, Valeo's etc. are the same way. When they heat up they reduce voltage which in-turn reduces current output. It is a self protective feature but one that leads to chronic undercharging on boats with large banks..
You may find that the alt does the same thing if using the Balmar alt temp sensor. These alts were never designed for high output applications and don't cool as well as an alt built for extended high output run times. The difference is the Balmar temp sensor can be adjusted and you can also limit the field to allow the alt to run at say a max of 50A vs. the 65A it is rated for. It can likely run at 45-50A all day long without over heating or going into temp limiting but you'd need to play with the field output to figure this out......
