Hello Yuki,

Thanks. Yes, there must be no QRM from the regulator and they are all 
switch mode devices. Anyway, i would have built it by my selfe anyway 
:-) A well conducting cheap MOSFET (such as IRF1404 
<https://dl.dropboxusercontent.com/u/19882028/Datenbl%C3%A4tter/irf1404.pdf>), 
a reference voltage IC with low power consumption (such as LM2936 
<https://dl.dropboxusercontent.com/u/19882028/Datenbl%C3%A4tter/LM2936.pdf>) 
and an OP amp as P-I regulator with a BIG time constant, this worked 
well in the past. I just need a fixed limitation to 13.8 V for the lead 
acid battery. Some of them worked well for more than 10 years on my 
previous solar system.
I will continue reporting...

73, GL, Stefan

That is excellent idea!
  <br>
I hope your server may take high sensitive echoes.
  <br>
  <br>
I and Mitsu/JA1CNM have established remote RX
  <br>
2 or 3km far from each own house. There is no
  <br>
power lines or housings within 100m range. And we independly put
solar-panel and floating battery.
  <br>
Our VHF link is F3E, and audio passband is limitted under 3kHz.
Therefore, RX is made so that convert  frequency 136 -139kHz to
suitable  audio spectrum.
  <br>
  <br>
General solar-panel voltage regulator make huge NOISE on receiving
frequency. We have to built serial regulator with big power
dissipation.
  <br>
  <br>
Good luck
