    Is the tabbing in the module itself the weak link when it comes to overcurrent issues? It looks to me to be a lot lighter than the cables themselves.

    I don't know--But it seems possible. Also the bypass diodes are another weak spot (undersized, poor to non-existent heat-sinking, in my opinion).

    Here's a couple pics of burnt tabbing. Presumably not from an overcurrent issue but from Kyocera's lead free solder problem.

    Hi everyone,
    Has anyone here used BYD blade batteries in their solar or backup systems? I’m curious about it

    Here’s the product page I’m looking at (for reference):

    Would love to hear your experiences or thoughts
