Inverter Upgrade Wiring

I recently installed 600W of solar using factory wiring, Victron controller and Color Control monitor plus a BVM712 I already had. For now I have 2 Trojan T-125+ 6V batteries but will eventually upgrade to Lithium.

For the next phase I'd like to upgrade to a Victron 12V 3000 inverter/charger over the factory 1K. I'd like to run "all" the AC outlets, Microwave, Fridge, and maybe even the roof air through the new inverter. I realize the current battery bank won't handle these kinds loads until I upgrade. Is there a good resource on how to do the wiring leaving the factory converter and fuse panel in place (with charger disabled)? I think this is an upgrade I can manage myself. Also would like to minimize cables to the batteries if any of the factory wiring can be consolidated.

I did a similar upgrade to our unit last year. Upgraded the factory inverter to a 2500w inverter/charger that has its own dedicated battery bank. I had to do some re-wiring and installed a sub-panel for all the inverter-served circuits. This required moving a couple of circuits out of the main panel and installing a circuit for the inverter/charger (net one less circuit in main panel). Also had to run a feed from the factory inverter location to where I installed mine (under dinette seat) to get the TV outlets onto the new inverter. Now I have every outlet & microwave on the inverter. Did not bother putting fridge on inverter as it would kill batteries too fast & it runs on LP anyway when boondocking. Same with AC units, don't need them on inverter as not enough battery to support them.

If you want details, PM me and I will try to dig up the schematic I generated & some pics.

Good luck with your projects!
