I self installed the entire system. The key to my system is the two Tesla Model S batteries. Everything else is built around these batteries.
If I were designing a new system today, I would forgo using the Tesla Battery Modules and build a DIY LiFePo4 battery bank using the 280 ah LiFePo4 batteries available direct from China.
I really like the 24 volt Architecture, however Victron has a new 12 volt 3000 Watt Inverter/Charger that will feed both legs of your 50 amp coach (if they make a 24 volt unit that feeds both 50 amp legs, I'm back to the 24v architecture).
As far as price; I saved a lot of money in two areas, the batteries and the Solar panels. The Solar panels are residential Solar panels and I bought them for $0.69 cents per Watt (today you can easily get equivalent residential panels for $0.54 cents per Watt). The Tesla batteries were 1/5 the price of Battle Born batteries.
The remainder of the system was control modules, the Inverter/Charger and all the wiring components.
Basically I got a $20,000 system for about a quarter of the price. Based on using the DIY LiFePo4 batteries and the lower priced Solar panels, today, I could save about $1,500 to $2,000 if I were to do a similar system.
FYI: Almost all my components are from Victron or Blue Sea.David and Peggy
