I know that looks confusing. I have an older 45 amp Inteli-Power in my '67 Trade Wind that I put in somewhere around 10 years ago or more. I have been very pleased with it. I just got a new Inteli-Power9280 from Randy at Best Converter (9200 Series
) to replace the 70 amp Univolt in my Excella.
It may be a bit of overkill, but I expect it to last for many years if the one in my Trade Wind is any example and will certainly handle anything I can throw at it. The 9280 is also 3½” longer than the 9270 or 9260. This gives it substantially more heat sink that should, at least it seems to me, allow the cooling fan to run less under most conditions. Excess capacity and less noise (at least in theory).
This Univolt is still working (HUMMMMMM!!!), but I have bad memories about the old one’s failure. I plan to install the new Inteli-Power tomorrow. More info to come.
