Isn't there any smart solar charger controllers to share PV panels ?

Hi

I am just thinking.... Putting a huge panel 8kwh all of them setup in xP and yS series but I want to make sure all of the circuit is looped into two or three smart solar charge controllers which will be parallel to each other connected to a single huge battery bank.

The idea is to ensure even if there is a failure of one charge controller, there shouldn't be a capacity degradation interms of production

I am afraid your logic is not good. A proper charge controller will try go get as much power (up to its rating or limits) to put into a battery. You can't have two chargers delivering 8k watts each from an 8k watt array. By design they would be limited by lack of available PV power. I think it better to have a spare on hand, maybe wired in, so that you just have to turn it on if needed.

Edit..I do have a pair of All-in-One units that you can set charge amp limits, so a person could restrict each of two to use no more than half what the array might produce.

It seems like it would work, but no, the controllers do not work that way.
If you want redundancy, it's best to split the array up between controllers,and as mentioned above, have a spare on hand.
