For a battery powered shack and field use, OH8STN/Julian's videos and blog are excellent.
His main focus is QRP field work for 'grid down' comms.? He's using some high-end flexible solar panels in the field, but his batteries are homebrewed from LiFePO4 and rival the commercial "solar generators" for much less money.
He's found the Genasun charge controllers to be robust and RF quiet.??
This blog post and three video set shows his design overview, build, and update process for a 12V 45 Ah battery suitable for shack and field use.
