Based on 4x SI and AC coupled SBs.
I tried to search the forum, but didn't get a definitive result.
I am pretty sure the answer to the question is yes based on that slightly older post of the guy building out a big SMA powered crypto miner system and also the post a couple of months ago where we discussed adding amps from a generator.
The recent discussion of mini splits - both direct solar and 48v variants prompted me to post this.
I would like various outbuildings to have AC and heat. But some of this is for climate controlled storage...which wouldn't need 24/7 operation.
I'm thinking that if extra SBs and panels allow for more amp capacity while the sun is shining, I stick to mostly conventional mini splits along with local (to the minisplit) panels and a Sunny Boy tied into my entire local grid. And the mini splits set to mostly operate while there is enough capacity being produced from the adacent panels to it. This could be accomplished with a KISS time/calendar based setting or one could bang their head against the wall and use something like home assistant to actually monitor the power being produced and turn on/off the minitsplits.
This setup would facilitate extra solar collection during the winter for the batteries in the power shed.
A few outbuildings that would benefit from 24/7 cooling/heat could use the 48 volt mini splits and local batteries, panels, and charge controller(s).
These outbuildings will be heavily insulated...foam and/or rockwool.
This would allow for max availability of amps available for power tools (i.e. dust collector and planer operating at the same time) in both the day and evening. I have just under 100 amps available from the Sunny Islands and batteries after the sun goes down. I am trying to maximize what I can use those 100 amps for. So shutting down mini splits in areas that aren't being used by actual people would be part of that plan.
And might prolong the time I have before I install a second system or third system and/or a SMA multi-cluster box to gain more amps . I am running oversized 3-phase wire for my "mains" but using just two legs right now while I have 240v split. Any 240v split phase runs are also oversized by at least a gauge over the NEC requirement (in other words, my wiring has extra amp carrying capacity if I need it).
Thoughts?
