This is Epever's latest model with more detailed controls, lcd, better internal protection, this is also the higher voltage 150V, suitable for 12/24 and 48V batteries and built in Blue tooth.
 
I choose Epever for our budget range off-grid kits because they have shown they last the test of time, I have seen Epever controllers on installs over 10 years old, still going strong. Epever have been around for 18 years and they have a rare quality of producing quality products at an affordable price.
