*What this means in simple terms*
This box is for 1 solar string only.
1. *1 String Input*: You connect 1 set of solar panels in series to it. Max 15A from the panels.
2. *Output*: It combines and sends up to 32A out to your inverter/charge controller.
3. *550V Max*: Your solar string voltage must stay under 550V DC.
It's basically a small combiner with fuses/breakers + surge protection inside to protect that 1 string and give you a disconnect.
