The controller you have will charge 12 or 24 volt batteries. Some do 12, 24, 36, 48, 60 and 72 volt banks. The MPPT part allows you to use higher voltage input and it will step down the voltage for your battery banks needs. Without going intoso i can a full on explanation why this is better lets just say it has the ability to harvest more of your panels output and can save money on wiring, fuses and allows you to use inexpensive grid tie type panels instead of expensive 12 volt battery type panels.
I need to suggest you read all the stickies at the beginning of the off grid section. study and absorb as much as you can. It will save a lot of Q&A time.
OK off for some quality time with the family.
So I can put 48 into it? Does that DC 150v mean I can input 150v into it and it will step it down to what it need to for best results?
thanks, and have a great evening
