This customer’s existing set up in 2021 36′ 5th Wheel Game Changer included the 7000 Onan and flooded lead acid batteries. He was disappointed on how much space the batteries and vented boxes took up in the front compartment
The Problem With Their Old Setup
The flooded lead acid batteries were never getting charged as it would take a minimum of 4-6 hours of shor/gen power every day. He wanted a solution that included getting rid of the acid batteries, keeping the 12v compressor fridge cold, room for gear and running the Whole Trailer without Gen or Shore power.
A 10kW battery bank (4pcs of 206AH of SOK batteries) and 3000 watt inverter would allow for silent, fuel saving Whole Trailer powered up on battery. The AC would run for 4+ hours.
I was able to fit three 350 watt panels on the roof for total of 1050w 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 Cerbo GX/Touchscreen 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.
We decided to add a 15 amp GFCI outlet in the basement on the drivers side and 20 amp outlet on passenger side that is only powered by generator or shore power, this can power the 80A stacked Lithium converter. This can charge the batteries much faster!
The Battery capacity is 824AH (10.4kWh), the solar can put in about 60A, The inverter/charger can put in 120A and the Progressive Lithium converter can put in 80A. This could add up to 260A or about 3 hours of charging from dead to full!
With the Cerbo GX online I am able to remotely see the system as if I was there. It will allow for troubleshooting, updating firmware, adjusting settings as situations change or allow for a deep dive on 6 months of history.
