If you intend to use the Victron 150/100, you will need to split in 5S2P panel strings. 195V is over the VOC rating of the 150/100. The...

I'd b very concerned with shadowing, especially with a single series string.

24V is looking pretty good to me now, but I remember reading somewhere that the rule of thumb is to use only up to 1kW of A/C loads with...

Would have to be in an insulated box versus just sitting outside in the elements I think. Or all the charge power will just go to the...

-13F seems cold but I think this is doable with self heating. Especially inside a compartment.

In a compartment, that I think will be "near room temperature" (or warmer).

The battery bank will be in an interior cupboard area and my plan includes forced air ventilation from/to the living space. I think it...

Yes. I see. Two of those are just slightly larger than the 48V pair and provide the same kWh total. Then I could switch to a Multiplus...

Can get rack mount 24Vs https://signaturesolar.com/eg4-lifepower4-lithium-battery-24v-200ah/

Lol. I hope you don't. That sounds rather unpleasant. I just copied/pasted the product documentation about the -25C...

I was recommending the SOK 48/100ah batteries compatible with Victron BMS-CAN. I call BS on this: I'll poo myself if you can...

The problem is if you are running a 48V system you'll need to get to at least 60V or so per string to get started with charging. It...

I agree it would be easier but my unfortunate space constraints are holding me back from that. To get the same (in kWh) storage capacity...

Yeah, that's fantastic. I hadn't considered the possibility of doing something like this. Thank you so much!

For example, on my 150/35s I can series 3 300W 37V panels. Charging can start at 5V above battery voltage, so once the array gets to 60V...

Cool! So I think you are saying I could use multiple MPPTs (in parallel) in this system (connecting a subset of the panels to each. Is...

There could be a small theoretical difference but you may have bigger problems with shadows from rooftop obstructions reducing your long...

I forgot to respond to your SOK battery comment. I did look at SOK, but I can't fit a comparable SOK battery bank in the small...

Thanks @ScrotusGobbleBottom! I think you (and others) are highlighting my fuse strategy is incorrect in a few places. I will rethink all...

Personally, I would use the 2/0 wire and fuse it at 100A. That way if anything happened, that wire would be perfectly fine except for...
