So my power needs on the AC side aren't all that big. Everything's 120V, and I have a few larger AC appliances (induction top, oven, and water heater) which each pull roughly between 1200W-1800W when they're blasting. Let's also assume my minisplit is often cooling me off at 600W.
My dilemma is that the Multiplus 24/3000 (currently ~ $1200) can support 2400W continuous, so whenever I'm off grid, I'm really only using one of these larger appliances at a time. Granted, that might make for good conservation behavior! But, it's a bit annoying I think that in the morning I need to _first_ make coffee, _then_ toast, _then_ heat water for a shower. If I'm going to do all those things anyway, it would be nice to do them at the same time. Hence, I'm leaning towards the Quattro 24/5000 (currently ~ $2800) which can do 4000W continuous.
The thing is, the Quattro is so overkill for me. I really wish there was a size in between. Today, I realized there _kind of_ is. I could put two compact Multiplus 24/2000s together for an effective 24/4000 (currently ~ $2200) supporting 3200W continuous. That's sort of the perfect size for me. But, when I searched how to actually run this in parallel, most of the search results are worrying. It seems overly complicated, even for a single phase set up. And, the compact version isn't really compact in a helpful way. It's actually longer than the normal multi / quattro models, it just had a reduced depth, so I'm not even sure it will fit in my under-the-counter electrical cabinet.
One last detail: given my energy needs, a 30A inlet suffices. That would satisfy my AC loads 95% of the time, and only dip into the PowerAssist infrequently (and at most 20A worth since I'm likely to have that 50A breaker - even the single Multi would handle this no problem). But diagrams for parallel multis always have 50a inlets because, why not, you get to harvest both legs. And I just don't need that. Is there an easy wiring diagram for 30a inlet to two parallel single phase Multipluses?
Sigh. Can't make up my mind. Any opinions here?
