Re: [LUG] OT: Charge Controller

Hi

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.

Victron 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?

Many thanks.

See you

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!
