24 volt battery bank?

Other than needing to use a DC-DC converter for the 12 volt system, what problems would there be in going with a 24 volt battery bank for a custom rig?

The reason for this is that Magnum Energy has a PSW hybrid inverter which can run up to 4000 watts, as well as take two 120VAC power sources at the same time (genset and shore power.) However, for this functionality, it requires 24 volts in the battery system.

the mobile version (MSH4024M) only accepts one AC input. And the MS series which does have 2 inputs won't do load support (run partial from AC input and partially through the inverter)

on edit:

Also check the manual on that unit.....won't take both inputs "at the same time" it would be either or, can just be wired for both without having to switch a plug or have a separate transfer. Actually this is the reason the hybrid/mobile can only take one input......inverter is attached to one input already to provide load support, in which case the output IS getting both inputs

One big reason 24V is a good idea can be found in the specifications section of the inverter docs.....check out the page with the efficiency comparison between the 12V and the 24V version :B
