I'm looking to buy the EG4 6000XP for my Off Grid Cabin. I currently have a Generac 8kva propane generator. Would I need this EG4 ChargeVerter to interface with this system, or can I safely connect the Generac Gen directly to the Eg4 6000XP?



EG4 states that any generator that would work with the EG4 6000XP would need to be an inverter/generator. If your generator is not an inverter/generator then you will need a chargeverter or else the warranty for the EG4 6000XP is voided.


Can I use the chargeverter to charge my battery bank while still outputting AC from the system Inverter or should I shut down inverter until batteries are charged?

Yes, that being said it will only charge the batteries if there is access power from the chargeverter. If there isn't than it will simply be powering the AC loads.


Doing some pre-planning for outlet box location, what are the cable lengths for AC input and battery output?

The AC input is going to be 6ft and the DC side is going to be around 7ft.
