Hi
I had several more questions on the solar controller
Will the controller work with Volkswagen panels?
Yes these panels work very well with a small battery and the controller.
This is a good match for a K1. A K2 really needs a little more power so two
or three VW panels can be paralleled. These panels can be had for the asking
at some VW dealers or for a few dollars on EBay. They are placed in the
windshield and plugged into the cigarette lighter socket of VW's to keep the
battery charged while shipping or on the dealers lot
A very nice solar setup can be assembled with an EC1 project box from
Elecraft and a Powersonic PS-1228 battery. This battery will fit nicely in
the EC1 with room to spare for the controller. This battery is 2.8 amp hours
so it should run the K1 or K2 with no problem. A 5 to 10 watt panel in full
sun will keep it charged even while operating.
Can the controller be left connected to the battery indefinitely?
Yes the controller goes into a maintain or float mode when the battery is
fully charged. The shottkey blocking diode disconnects the controller when
the panel output drops below the battery voltage so there is only a few
micro amps of current flow when the panel is in the dark.
For larger setups I have used a 35 amp hour SLA battery of the type used on
power wheelchairs and a 70-80 watt panel with the controller. This will
operate a K2/100 at 50-100 watts out. This was the setup for field day last
year used by one of the operators here
Does the price include shipping
Yes in the continental US by first class mail
Thanks
