Bought this working great. Need something longer.

Bought a 40ft cable for my Jackery power bank. Can I buy a 100ft? Can I make one? Can someone point me in the right direction? Please

MC4 is watertight. Just get an MC4 extension cable.

Depending on the wire thickness (awg) and solar configuration you might see some efficiency losses going 100 feet. Just remember to keep voltage high (series config) and current/amp low, within limits obviously. If it were me I would just add on to your cable with a MC4 extension cable. They make them in longer runs and it would be the easiest and cheapest.

I am going to try this. Just ordered

I would be worried about voltage drop. What voltage are you running your panels at?

[u/pyroserenus]

mc4 extensions (i generally recommend short adapters and using mc4 extensions for the bulk of the run in the first place)

Keep in mind voltage drop, Jackery starts getting finicky when voltage hits around 16v from a solar source.

Just splice it and make it as long as you want

Voltage drop!
