       * Inversion from 24vdc to 110vac is more efficient than inversion from 12vdc.
     * You have large, power-hungry appliances that can run natively off of 24v
-      * Some [[food:refrigeration|DC refrigerators]] can run off of both 12v or 24v, and are slightly more efficient when running off of 24v

+      * [[hvac:solar_ac|Off-grid Air Conditioning]] can be slightly more efficient with 24v native systems, and will allow smaller wires to be used.
     * You have a lot of long, large cable runs
       * 24v doesn't have as much voltage drop as 12v over a similar distance, and can use smaller/cheaper cables.

 ===== solar panel array =====
-Pick a solar panel array output on battery bank capacity.  A common **rule of thumb for matching panels to battery bank** is that there should be **at least** 1 panel watt per amp-hour of nominal bank capacity.
