So here’s the thing, I already have a 24v 15kw battery bank with dedicated 24v charge controllers with 24v grid tie inverters working well.
But I want to expand, and most systems now use a 48v battery pack.
I have a 2.5kw 48v inverter, but can’t use it with 24v. I’ve rigged up a very small 48v test battery and it works well.
The trouble is, I can’t use my large solar array as that’s all linked to 24v.
So I’m toying with a high wattage boost converter to go from 24-48v.
I know this will be very inefficient, but what matters is getting more current into the house grid from battery.
Has anyone done this? Will a converter just go up in smoke?
I’m loathed to have to build a second battery bank just to run the 48v inverter without having access to my 4kw of panels…
This is the sort of thing I’m looking at;
