From a reliable source http://www.magnumenergy.com US made able to handle the some times higher voltages encountered during the winter with a solar system.
The Magnum (and my old Freedom 485) would both throw faults and shut down when solar charging voltage got too high -- 15.5VDC I think. This was just a case of "dueling chargers" -- the inverter/charger & the solar charge controller.
Had this issue with my Classic 150 solar controller, but I just used a setting to throttle back max voltage output from the controller.
This "ability" to handle higher voltages is just an inverter/charger protection method and has nothing to do with winter, spring, summer, or fall.
