Multiple Chargers:
One of the reasons I spend so much time testing various power, energy,
and cost-viability concerns with my old 92 Winnebago is to learn what
does and doesn't work well.
There are three types of charging systems in the Winnebago. The
Engine 140 amp alternator, the Onan Generator powered 45 amp inverter,
and the 150 Watt Solar Array. I had to be very careful to job-isolate
their functions. (It required, however, only a 120 amp isolator from
the engine alternator.
One time I had both the 45 amp inverter as well as a 20 amp automatic
car battery charger working at the same time in order to expedite the
recharging of a small AGM array of 5 50amp hour orbitals. (The point in
studying the energy and power characteristics of the highest number of
small tasks for morning breakfast in the Winnebago was to try to never
run the rather loud Generator and also due to it's resulting CO2.).
Also for light computing at lunchtime when also small electric
appliances needed to be used).
Result: You can not have two or more 120 volt-powered chargers
recharging your batteries at the same time. They will be confused by
each other and cause overcharging. The solar array has a simple 3-level
pulse width modulation regulator that works extremely well for its cost,
(as also I have mixed two different sized panels on the roof). (Mark
Farver advised me well on that one!!) It is unaffected by either the
engine's 140 amp alternator, or the 45 watt house inverter.
Decommissioning the Onan Generator for 98% of it's start-ups and
run-times has worked *perfectly* well with the relatively small array of
150 watts on the roof, which was the appropriate sizing for the simple,
but important jobs I need to be done. (The location of my $85 a month
RV "office" is perfectly north-central enough to save 8 travel hours a
week to go home for lunch, and, an estimated 10 gallons of gasoline a
month/ 200 pounds carbon dioxide, not to mention that the remainder of
the life expectancy of the Onan is preserved so as to prevent it's
replacement during the remaining useful life of the RV.

> I was wondering if anyone has built or thought of displacing the cost of a large high voltage pack charger with multiple smaller 12V battery chargers that could run in parallel on a series connected pack, each with microprocessor controlled independent three stage charge regime (either IUU, IUI). On the surface it seems doable: A 30 A vector charger can be had for less than 80 bucks. 12 of those would be $960 - far less than a Manzanita, and with implicit charge equalization.
