More FrankenScamp Upgrades

I have just finished a major upgrade to Frank.
I have installed two Chin's 100 Ah LiFePO4 batteries, Victron Smart Shunt and a ProMariner TruePower 2000PS 2000 watt pure sine inverter.
The previous Epever Tracer 4210 MPPT solar controller was retained as well as the Progressive Dynamics PD4540 30 amp (AC) power panel.
The 2000PS inverter has a built in transfer switch and I powered it directly from the 30 amp incoming breaker at the twist Lock 30 Amp inlet connector that feeds the "original" power panel. There is also one additional breaker in this box that powers a 120 VAC outlet that is "alive" if there is an inverter problem.
That 30 amp main breaker feeds the inverter input and passes either directly through in manual mode or is the input to the built in automatic transfer switch in the inverter if selected. The 120 VAC from there goes to the PD4540 power distribution panel for the normal trailer AC loads.
The two Chin's 100Ah LiFePO4 batteries are connected in parallel for 200 Ah 12 VDC to the inverter (200 amps continuous for as long as it lasts) through a 200 Amp circuit breaker with 1/0 welding cable.
The batteries are charged either from the 300 watt MPPT solar controller or the PD4540 battery charger.
The DC from the batteries is fed back to the PD4540 for the DC power distribution as before.
The negative return of the batteries goes through the Victron Smart Shunt that tracks voltage, power, and state of charge and can provide readouts and trends via a bluetooth connection to a cell phone to keep track of the condition of the electrical system.
I installed this so that we would be able to use our all electric FrankenScamp without a power connection for brief usage of the microwave, coffee maker and electric skillet(s) and toaster. The system will even power the AC/Heater for a while (maybe 2 hours or so) Actually the AC is less power than the microwave and is inverter powered so there is no starting surge involved with any of the AC appliances.
Part of this upgrade was replacing a failed Norcold 490DE refrigerator with a Norcold DE105 "Danfoss" compressor unit.
So FrankenScamp has been refreshed and ready for more adventures as well as service as the Scamp Command Vehicle for Ham Radio ARES work and a Bug Out Box in case of hurricanes aimed at our area of north Florida.
Now to set up the various computer connections to the solar system for logging and trending because that is what geeks do...
