Who sells a small RF quiet solar charge controller?

I'm looking for a small RF quiet solar charge controller to charge a battery for my K2.

Who makes a good quiet one?

Thank you

Cirkits.com. The SCCS-3. The owner is a ham, I believe.

blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; } Flint Hills Radio makes a nice, compact charge controller. Here's his web site:

I have one of these and it's completely silent except for the tiniest
"tick" when it begins a charge cycle.

Re: Who sells a small RF quiet solar charge controller?

Just check your input voltage on the controller and the Vmp of the solar
module. You may need a buck transformer if the module voltage is to high.

Genesun, Genasun, Genasun. They work very well and they are quiet. Make
sure you get the right model for the battery chemistry you're using.
They make models for lead acid, LiPO4, and Li Ion.

Re: Who sells a small RF quiet solar charge controller?

In reply to this post by Elecraft mailing list

I use a Genasun GV-5 and a Bioenno Power 4.5 Ah LiFePO4 battery to power
my KX2. I agree with Jim. These components work great together--but
with one exception: I can't float the battery with the GV-5. When the
battery approaches full charge, its internal monitoring disconnects the
battery from the circuit, causing the GV-5 to go to open circuit voltage
of >= 18 V in full sunlight. According to Elecraft, this would fry my
radio. So, as a work around, I use a DPDT switch to keep the solar
panel and the load on separate circuits, selectively connecting one or
the other to the controller. This way, when the panel is connected and
the controller signals an over voltage error (according to Bioenno, this
doesn't harm the battery), I know that my battery is fully charged. I
then disconnect the panel and connect the load by flipping the switch.
I don't mean to hijack Harry's thread--hopefully this post adds value
for him. But I wonder if there is any other combination of small,
lightweight MPPT controller and LiFePO4 battery that would permit
floating the battery.

Jim Cordill, KI0BK, at Flint Hills Radio makes an adjustable solar charge controller.
Solar
It's small and will do what you need. If you have a question or there is something else you would like to see in it shoot him an e-mail.

The ultimate quite charge controller, an ON/OFF type that turns on when the battery voltages falls to 13.1v and turns off when it reaches 14.4V and no switching noise.

I have one of these and a Genasun GV-4 for SLA battery chemistry.

Re: Who sells a small RF quiet solar charge controller?

Yes. The difference is that the Genesun is an MPPT controller, which
uses the solar panel(s) far more efficiently, allowing the battery to
charge faster, but still within the parameters of the chemistry for
which it was designed. A local ham suggested the Sun Force as a low cost
option, and it does, indeed, work. And it;s quiet.

Yes. It's called a hysteresis controller. Very simple. Which is why it's
quiet and inexpensive.

Re: Who sells a small RF quiet solar charge controller?

I use a Genasun GV-5 and a Bioenno Power 4.5 Ah LiFePO4 battery to power my
KX2. I agree with Jim. These components work great together--but with one
exception: I can't float the battery with the GV-5. When the battery
approaches full charge, its internal monitoring disconnects the battery
from the circuit, causing the GV-5 to go to open circuit voltage of >= 18 V
in full sunlight. According to Elecraft, this would fry my radio.《《《《《》》

Wouldn't the 18v be on the ARRAY side of the circuit, not the LOAD side,
therefore the radio would be protected and not see the 18v? Am I missing
something? Is the radio connected to the battery?

The "Moohoo" on Amazon, that Nicklas suggested has an issue ( according to
reviews) with array voltage dropping ever so slightly, it goes offline.
Typical of the "chenease" junk...

I have ordered The "SBCC", by KI0BK. As someone suggested earlier is a 3
stage controller, battery friendly. Those using it claim it's quiet and
EFFICIENT, very important at $1 a watt and mostly cloudy where I live.
Stick with one designed by a ham, who's goal is radio quiet-
YMMV, good luck es 73!

blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; } I use Phil Salas', AD5X, automatic voltage reducer to protect my KX3 from over voltage issues with LiPo batteries. This should work with a solar panel as well. Very small, light & fun to build. Contact Phil for the board.

I use the unit in the link below and it is quiet. I keep my K3 battery bank
with a 100w panel connected to keep the system ready to go.

Re: Who sells a small RF quiet solar charge controller?

I use a tristar TM45 MPPT controller with two 12 volt solar panels in series. I went with MPPT not because of efficiency but because I can still charge when it is cloudy or there is shade on my panels. I have my panels mounted on the top of my van and it keeps my 140 amp hours of batteries charged year round while I use my radio and my 12 volt refrigerator.

I have seen some misconceptions about MPPT. The best reason to use MPPT is so that you can put multiple solar panels in series and you will not exceed the maximum input voltage of the controller. The controller will continue to charge even in partial sunlight just as long as the input voltage exceeds the battery charge voltage (in this case 14.xx volts). Since solar panels in series ADD voltage, with two solar panels you get a 24 volts (well, more like 32 volts in full sunlight) and when those panels are in shade, the individual panels may drop down below 12 volts but the sum of the two will be much higher than the required charging voltage.

My off grid system in on/in my van runs 24/365 even in the great North West where it is gray for 6 months out of the year!
