48v eg4 inverter and battery

Need info on doing a 48v off grid system. I got the eg4 6500EX and the eg4 life power battery. Also got Solarever 445W Split-Cell Mono Solar Panels 445w x6.

Can someone point me into what I need to run this off grid without shorting anything or destroying it. I plan to keep it as backup if needed. Not running it all the time. What other things are recommended to use with it. Brakers, plugs, anything needed for effective use.

Have you looked at Will Prowse diysolar video from two weeks ago? He goes through everything needed for that exact same setup.

I looked at his stuff but I want more info on PV disconnect and braker use for 120v AC output

The 6500EX manual states in PV connection section:

NOTE: Please use 600VDC/30A circuit breaker. The over voltage category of the PV input is II.
Please follow the steps below to implement PV module connection

Maximum AC output will be 54.16 amps (6500 w / 120v) you can add 25% more room to the breaker but could never trip because will trip internal breaker first.

Before you buy anything you need to define how do you want to run the inverter, as dedicated new circuits or moving existing circuits to a new subpanel. In the search of the forum you can find valuable information about that and in resources you can find guides about sizing breakers, wiring, etc.

There is a pv disconnect and breaker attached to the inverter checkout - go back to SS's website and look at the inverter, they are suggested products.

For the 500v SCC there is a second DC-DC converter board added above a standard SCC board from a 500vdc internal HV bus, 230vac inverter to take SCC 500vdc output down to 250vdc internal HV bus for the 120vac inverter. The extra DC-DC converter will reduce PV SCC power conversion efficiency a couple percent.

The extra DC to DC converter stage could provide galvanic isolation between AC H-bridge and PV inputs that is not present on most HF inverters. I would still use double pole breakers to cut both PV pos and neg lines just to be sure.

Sorry I didn't mention that I only want to run one server rack battery for now with possible expansion later. The PV input I'm looking at is only 445w per panel and I want to run 6 of them. Would it be better to put 3 in parallel and then 2 series to the system or run all in series? The output I'm looking at is one refrigerator and some lights, with possible other minor appliances for when the grid is down. I don't want to run it all the time and I will make this thing portable. I want to be able to recharge the system while using it, and keep it toped off for the just in case. Cost savings is key for me as this stuff is expensive. So easy set up and breakdown of all the connections is needed. I plug everything in charge it and then run the system for need, unplug and store away. So not always on.
