HELP! Hooking up new inverter for solar

I have a 1976 31' International. In the mid-90's solar was added. They installed a TRACE Engineering DR Series Power Inverter/Charger and 4 batteries. The inverter has since failed.

With help from a Sunelco dealer I bought a XANTREX Prowatt SW 1000 inverter and an Iota DLS 30/1Q4 charger. I'm at a loss on how to hook it up!! Have a number of wires coming out of the old inverter that connected to the wires from the Airstream. This NEW inverter has no external connecting spots for these wires, only 2 plug-ins.

Soooo, I think I'm just missing something simple here ..... I would appreciate any help or advice! Thanks so much

IF you haven't already, I suggest you read the manual. It tells you how to hook it up. Two of the wires from the trailer are the 12V positive and negative cables to the batteries. Others are probably the shore power input and AC distribution. Since, to my knowledge, an inverter was not standard with trailers of your vintage how the new inverter and charger hook up will depend on how the original system was wired.

That said, with a separate inverter and charger, you are missing a function of the original inverter/charger, the transfer switch that powers some, if not all, of the trailer AC loads from either the inverter or shore power, whichever is available.

Further, it sounds like your previous inverter was intended to be wired into the trailer's 120V AC power distribution and this inverter has only the 15 amp receptacles. This may or may not be compatible with your trailer's wiring setup and the loads presented to your previous inverter.

I'd suggest you obtain the services of a local RV-knowledgeable electrician to understand how your trailer was originally wired and how to wire up your new equipment.
