This customer’s existing set up in 2020 28′ FB included the 5500 Onan and flooded batteries that left him hoping to keep the furnace running through the night. He wanted a solution that included getting rid of the acid batteries, more room for gear and running AC off batteries to keep more fuel for the toys!
A 3.6kWh Battle Born battery battery bank (3-100AH batteries) and 3000 watt 12v inverter would allow for silent, short term Air Conditioning, microwave and TV off battery at any time of day or night. The AC would run for 2.5 hours.
I was able to fit two 350 watt panels on the roof for total of 700w to help charge and offset inverter useage.
I installed a Victron Mutiplus 3,000 watt hybrid-inverter to run the entire trailer from battery power. Customer opted for the onboard display of the Color Control which orchestrates all of the parts of the system well. It will data log, view and control the electrical systems. This system as programmed will just work off solar, generator or shore power seamlessly. In the event of something not operating as planned I or another Victron Specialist has the ability to see, analyze, control and update the system
