High Efficiency 60A Solar Charge Controller For Solar Panels Up To 750W (12V)

It wont be long and i can start fitting my solar System for my 12v - 240v.
I am looking forward to getting my money back on free electric from the sun. I know the summer months are going to be mint. May need to use the battery charger in the winter.
I have two 410W solar panels coming.
I have added the Numax battery charger. for someone to tell me why it has one N and two L. Is this so i can have two battery banks on charge.
Thank you for watching my videos.

I fell asleep three times during the video. Could you put a bit more enthusiasm into your voice for the next one?
