True, but an isolator does not fulfill the same set of requirements that
the combiner does.
It's the same with the buzz box, which is also quite simple and reliable.
But it is also noisy and will sulfate batteries with its constant voltage.
A newer converter/charger will use a multi-stage charging plan to keep the
batteries charged without sulfation, and to charge them more quickly in the
first place.
And, with that greatly improved converter/charger, it's now reasonable to
want to charge or tend all the batteries if charging any of them. The
isolator charges the house battery when running the engine, and that's all.
With a combiner, that fancy new converter/charger will also tend the engine
battery while the coach is plugged in.
The Yandina combiner will connect the two batteries any time there is over
13.2 volts present on one of the two banks. It will isolate the batteries
when there isn't. It does not use a big diode, and does not get hot. It's
potted in epoxy, so no worry about critters making a home in it. It's quite
easy to install. It remembers its there, unlike Ken Burton's $1 combiner (a
wire with two alligator clips), which is subject to advanced CRS. Finally,
it's no more expensive than an isolator, especially if you wait for the
occasional deal--It's significantly less expensive than the BlueSea.
