Hey guys!

New setup here and I'm trying to figure out if what I have in mind is possible. I can't seem to find the answer through general research. I'm trying to split the solar panel output. Basically I have x4 100 Watt panels and want them to go to both an Ecoflow(directly connected), and a charge controller which will connect to a battery array. So the two power flows from the 4 panels will go:

1) x4 100 Watt panels > Renogy 40Amp controller > battery array > inverter
2) x4 100 Watt panels > EcoFlow Delta

If I use splitters to run the panels to both systems, would that work? It's my understanding that the charge controller does some voltage scanning on the array to pull charge for the batteries. I want to make sure that that won't burn out or cause problems with the EcoFlow. Please let me know if I need to clarify anything, and thanks in advance for the help!
 
You CAN split solar with PWM controllers but NOT with MPPT controllers.

I don't think anything will burn out, it just won't charge in an optimal manner.

2x panels supplying each controller would be my preference.
