Did you actually call them and see if they have a discount coupon, etc.? Like many brands the advertised price is the same, but the dealer can sell for less. I am curious as to your Quattro choice as most folks go with the Multiplus.

I have not. I’m not quite that far yet. Quattro only because I didn’t see a 5kva 120v MultiPlus. I’m wanting a dual setup so if one goes out while we are on a long trip to Alaska, I have a “spare” so to speak. I could use two 5kva 230v MultiPlus units feeding an auto transformer to create split phase, but I not sure I’m a fan of relying on paralleling to work. I think I’d rather have two Quattros, one feeding each side of the main panel. A side benefit of the Quattro is being able to eliminate a transfer switch, not that it matters that much. If I’m missing something, I’m wide open to suggestions.

Goal is 10kva total, redundancy, enough batt storage to run one A/C unit and the fridge overnight without a genny, and 48v DC to lower the current values involved.

Why do you need 10 kva? If you ran twin victron multiplus', you could easily run either A/C unit from a single 3,000 Watt multiplus.

Another option is to get a multiplus II with two 120v outputs, one inverter runs the whole house. I get that you would loose redundancy with the multiplus II, but Victrons have been operating on boats for years, I am not sure you really need a backup Inverter. But, if you do, look into the twin 3,000 Watt multiplus', just to save some money.

Note: I believe the multiplus comes in a 48v version.

Note 2: I have a 310GK and can run an A/C unit off my 3000 Watt multiplus with ease.

I’m dreaming big @SolarPoweredRV.

You could parallel 3 of the MultiPlus-II 2 x 120v models. Those don't have a 48v model but do have a 24v model. That would give you 9000VA with FAR less complications and is more user-friendly. Running Quattro in splitphase is the old school way. It works, but it's a pain and more costly. 3 MPII will run about 4500 bucks for the inverters total.
