Would it be more safer to buy coins instead of mining? After calculating the costs of buying cards and setting up solar panels with batteries and inverter i see that costs are too gigantic if one plan to run cards for 24 hrs everyday, is anyone mining using diesel generator? Bad idea?
The only way that makes any sense for solar at this point is to mine only when your system is producing enough power to run your equipment and shut down overnight.
Make it automated so you don't have to think about it and just let it run.
Don't even think about trying to run 24/7 with batteries.
Depending on what country you are in diesel may be still a viable option, look into the Lister low RPM engines, they run forever with very low maintenance and very low fuel usage.
