Dscheisse Bernd, das ist für mich der Elektrobitcoiner
What would change if we don't want an off-grid system?
I.e. use power from panels, and use AC/DC PSU for the shortage/night time usage?
Say i need to run ~120 W miner. Backing up with grid means id use 0 to 120W from grid... How to loadbalance keeping consistent 12V supply?

Hi to everyone. 
In this post I will share my knowledge about building a solar power island like the one I build myself to power my computer and router. Of course everything you are about to learn from this guide can be used to set up a raspberry-pi-driven mining-plattform thats brings mining for essentially free (of course: assuming you got enough sunlight.)

Platin: 1x 150Wp Solarpanel (€ 199,00)
Gold: 1x 130Wp Solar Panel (€ 119,90)
Silver: 1x 80Wp Solar Panel (€ 79.90) (Thats the one, I am using.)
Bronze: 1x 30Wp Solar Panel (€ 39.90) - Solar Charge Controller
Platin: 1x Steca PR3030 (€ 129.00)
Gold: 1x Steca PR1515 (€ 90.00) (Thats the one, I am using.)
Silver: 1x Steca PR1010 (€ 79.90)
Bronze: 1x lux.pro 20A (€ 23.99) - Battery
Platin: 1x RPower Longlife GEL-Batterie 240Ah (€ 599.00)
Gold:1x Banner Sitting Bull 100Ah (€ 128.80)
Silver: 1x Varta Dynamic Blue 60Ah (€ 72.00)
Bronze: 1x Phaeton 20Ah (€ 47.50) - General accessories (You will need this regardless which setup you chose)
1x Profiline solar power cable 3m (€ 22.90) (Thats the one, I am using.)
1x Battery connection cable with fuse-clip (€ 27.90) (Thats the one, I am using.)
1x Autek 12V to 5V/3A USB-Converter (€ 9.47) - Optional accessories
1x Raspberry Pi (Kit with cables, card and stuff) (€ 59.99) - Accessories for powering an ATX-Mainboard
1x PicoPSU 12V/90W (€ 32.95)
1x PicoPSU 12V/160W (€ 45.95) (Thats the one, I am using.)
1x M3-ATX 6-24V/125W (€ 52.95)
II. Setup
- Step 1: Make sure you get the most efficiency out of your solar panel.
Use the following chart to find out the best setup:
"Dachausrichtung" means roof orientation.
"Dachneigung" means roof pitch.
- Step 2: Connect solar panels, solar charge controller, battery and USB-Power-Output
2.1: Always take care of correct polarity.
2.2: Connect the solar panels positive pole with the controllers positive solar-panel-jack and then connect the negatives.
2.3: Connect the batteries positive pole with the controllers positive battery-jack and then connect the negatives.
2.4: Connect the Autek-12V-to-5V/3A-USB-Converters positive pole with the controllers positive load-output-jack and then connect the negatives. - Step 3: Connect your Raspberry Pi along with your ZTEX/Cairnsmore/whatever-you-may-want-to-use
Congratulations! You are now mining bitcoins using free sunlight. Consider yourself being a champion.

IV. Comments
One can of course also interconnect multiple batteries in parallel to increase the capacity. Is possible, for example, the use of used truck or particularly hot: Forklift batteries such as this one.- In principle both, direct current and alternating current devices can be operated with such an investment. However, if you want to run AC appliances, this requires an inverter. These are available in cheap and expensive. Attention: The inverters output side provides either true sine wave or only a rectangle "wave". Rectangle wave voltage can permanently damage electronic circuit boards. The difference between rectangle wave and sine wave voltage is as follows:
