Thanks for all the replies. What I am building is a bike
attached to an alternator and battery. I am using kit that I
used to use on a small solar array. What I am hoping to do is
to set up a system that measures output. So, we would have the
bike outputting the power into a battery, along with solar
panels and a small wind turbine. The idea being to measure the
output each system makes. Will I need a separate charge
controller for each system please? Is there a way to measure
output so it shows to a bunch of young people? Many thanks. ---
See you

Energy are good, Morningstar controllers I've had
experience with .. you get what you pay for ...
MPPT is the maximum-energy tracking algorithm for
maximum efficiency from your panel (solar).
YMMV if you're not using it for solar use. The main
other factor, aside from current-/power-handling is
maximum array voltage, else you will blow your
controller up!
Best,
Michael.

Have a look at the controllers from a
company called Victron. I use their Solar charge
controllers and find them a top product.

Hi All
Does anyone on the list know anything about charge
controllers please?
I am finally building a bike generator. I have a
fairly cheap charge controller that will do what I
need it to do at the moment. But I want to upgrade
or need some advice on how I achieve the next step
please?
Rather than go on unless you need me to can you
contact me off-list whoever can help please?
I would not use a charge controller for charging a battery from
an alternator - they tend to be used to make the higher voltages
of PV suitable for charging so use that for charging the battery
from the PV and or solar (probably dont use together) while the
alternator side is disconnected and vice versa. The alternator
may or may not have a 14.4v regulated output for charging the
battery. If you would be interested in digging deeper and
possibly working on something I do have an interest in this
stuff and have a long unused degree in electronics I'd love to
work on an Open Source project for this sort of thing. Please
feel free to contact me off list but be warned - I have a deluge
of ideas!

Also happy to pitch in - there are some interesting challenges
therein!
