Battery Bank to Inverter Main fuse
MegaFuses work great and cost very little money, and are preferred over the typical ANL fuse you would find from most solar distributors. Unlike ANL, Megafuses can be used with 48V systems and have a higher disconnect amperage. Stick to these fuses if you do not want to have problems with your 12V system.
(if you are building a large 48V system, scroll down this page to "T Class Fuse)

48V Lithium Battery Inverter Fuse: Class T
The ANL fuse above works great for most 12V systems...
But if you are building a large 48V lithium based solar power system, the arc that it can create in a fault can be massive! So large in fact, that the ANL fuse above will not save your system if a fault were to occur.
In this instance, you will need a T Class fuse. This fuse can work on any size battery bank, and will protect your system better than anything else around.
These are more expensive than an ANL fuse, but if you are using a 48V battery bank, these are required!
