Author Topic: "Smart" Controller for Solar Panel Chargers  (Read 1773 times)

My station runs off of a 97 AH gel cell, and I would like to install a solar panel to keep it charged.  I currently use an AC powered charger made by A&A Engineering that tapers off and shuts down as the battery becomes fully charged.  Is there a solar panel controller that does the same thing? Thanks. K5NT, Richmond, VA.

What you need is called a "charge controller". Basically it does the same thing as your automatic charger.

Some charge controllers contain a switch mode supply to generate voltage required for + lead switching and these can cause RFI in the receiver if the antenna is nearby. Others avoid the supply by switching the negative lead or they "shunt mode" that dumps the excess solar panel power into a load resistor.

You should be able to find plenty of systems and info with a Google search.

Harbor Freight lists several of these on their website.

I have a charge controller on my panel.  I don't know how "smart" it is, but it has kept a forklift battery happily charged for five years.  It is a 10 amp version and cost about $60.  Don't remember where I got it from either.  The panel is a Uni-Solar, maybe there is a website or something you could get more info from.

I use a 4 amp Micro M charge controller with my portable solar arrays.  It has the advantage that it's RF quiet.  Plans are in the ARRL Emergency Power book, which is a good reference for what you're trying to do.
