Hi Zdenek
Thanks for sharing your setup.
I think that a 12Ah to 16Ah battery is enough for almost all latitudes: The most important is the solar panel, which should be around 40 to 50 Watt. Such panel even during days without strong sunlight, can power the system and at the same time give enough charge to the battery, to compensate the consumption during the night.
I'm using a 14Ah Pb battery and a 50W monocrystaline panel, and never had a problem. Last year we had here in Portugal a harsh winter with several consecutive days without clear sun.
PS: Don't tell anybody, I'm still using an "old" TX v2.50 board.
