Most solar panels have a male mc4 plug on their negative wire and a female mc4 plug on their positive wire. The xt90 to mc4 cable provided with the ac200L has the same configuration as the solar panel with male mc4 plug on the negative wire and a female mc4 plug on the positive wire. So they cant be connected to a solar panel because of this. Why doesn’t Bluetti change this so that the provided cable that comes with the the ac200L can be used right out of the box? I have to modify this xt90 to mc4 cable by changing the plugs on the end to the opposite gender to be able to connect it to my solar panels which is a big inconvenience. Does Bluetti sell an xt90 to mc4 cable where the black negative wire has the female mc4 plug on it and the red positive wire has a male mc4 plug on it? Why isn’t that the standard included in the box?
Have you taken a multimeter to them?? This practice is common in this industry to allow for adapters to be used such as car charging or individuals who have preexisting panel setups or just want to use extension cables. I always recommend testing with a multimeter to verify all connections and voltage requirements as it could have been an oversight in your specific case, but I’d bet that it’s intended.
I was curious when I first got into this hobby as well lol but all is well.
Hi,
It’s the norm actually. Can you share a picture of both your panel’s connectors, and the XT90 adapter?
Extension cords are always of the opposite gender on the side of whatever wires they extend.
Just checked my AC200L’s cable, and can confirm this is right.
Hi @Bstores, We guess that you are using third-party solar panels, is that correct?
Our products are designed to be compatible with our own solar panel specifications, and the interfaces may not be fully compatible with all other solar panel connections.
In this case, you may need to purchase an adapter to handle the connection.
Thank you to m.briney and Derceto for their help and answers.
