Just looking at the manuals, the 100/50 doesn’t list 48v use. 2 x 100/20 controllers would handle that array.

Try the MPPT calculator to work out the best controller for your panels.

The Nissan Leaf modules normally don’t get replaced until they are down to 60-70% capacity. That means in reality that battery will have around 2.1-2.5 kWh capacity. 2kW of solar seems excessive for that size battery, what are you planning on using the system for?

Thanks Vance

trying to design a system that would keep power and lights on when the grid goes down.

It would not be grid tied only off grid

interesting about the battery was hopping to get more than 2.5 kWh capacity.

I have never used 48v before only 12v systems
