  On the floor I have a 60A Precision Dynamics charger/supply
  floating two Trojan 27AGM batteries (~200 AH) installed
  outdoors and connected with 4 AWG cables, a 1500 VA UPS for the
  computer equipment, and a smaller UPS for the telephone system.
  The PD charger/supply comes from the world of RV power, and
  picks up the full load even if the batteries fail.

  On the power panel above the operating desk, there's a
  low-voltage cut-off relay and two "battery boosters" each
  feeding a bank of 8-12V DC circuit breakers rated for marine
  use.  Digital metering is provided for battery charge/discharge
  current, bus voltage, and output voltage of each "battery
  booster".  Internal wiring on the power panel is 8 AWG with all
  connections properly crimped per industry standards.  This
  custom panel was designed by myself with the assistance of our
  firm's communication site DC power distribution specialist, a
  nationally recognized expert in that field.

  In the operating console are my K2/100 plus an assorted
  collection of VHF/UHF transceivers, HF receivers, VHF/UHF
  scanners, TNCs, and assorted accessories.  Works quite well.
