Our 2013 25FB International Serenity had the factory installed 600 watt inverter. The two TV power outlets and one under the dinette were the only ones that got 120Vac from the batteries. Our dealer installed single 150 watt solar panel could NOT bring the batteries to a full charge with full sunshine all day after the furnace ran at night at the Albuquerque Ballon Festival last October. We had to run the Honda 2,000 watt generator about an hour to get the batteries to 100% capacity for the next night's furnace run.
We ordered our new Classic with only the 50 amp service upgrade. Thus all the trailer's 120Vac outlets lack power when the service cord plug is pulled from the service pole beside the trailer. Everything has to run off the batteries at 12Vdc and or propane.
Now the Classic is undergoing a major solar system installation that includes eight 100 watt solar panels with a Magnum MS2812 pure sine wave inverter/converter and a TriStar 60 MPPT solar charge controller connected to four Lifeline 6Vdc 300 amp hour batteries. Every outlet will be energized on both shore power and battery power.
I will have to manually select the propane option for the refrigerator rather than the automatic mode and even the air conditioner(s) could be run for a few minutes for a lunch stop beside the road.
Having said this, the installation and parts are expensive. During this process, the trailer will also acquire disk brakes.
