Why do I think this is the best battery?
Let's compare the features of these popular server rack batteries and determine which is best for off grid solar? One is the Jakiper Pro from Orient Power, and the other is LifePower4 from Signature Solar.
LifePower4 battery from Signature Solar is my favorite for building up a large scale system. This is for people wanting to back-up their whole house, or go off grid completely. Combine 2 or more batteries inside the enclosed cabinet for a perfect setup. The 48V batteries from Signature Solar come in 2 versions, with or without a screen. I don't think the screen version is worth the extra cost if you plan to use a central shunt anyways.
