I'm a bit confused on some terminology in the Sunny Island 6048 manual. Under the AC1 terminal connections, it has this statement:
***************
Cable lengths in single-phase, parallel, split-phase, double split-phase and three-phase systems
The AC cables between the Sunny Island and the sub-distribution of a system must have the same wire size and the same cable length for all parallel connected devices.
***************
My setup is using two Sunny Island 6048 inverters for 120/240 split phase home power.
The Master AC1 goes to Line1
The Slave AC1 goes to Line 2
Are these inverters considered to be operating in parallel? To my understanding, parallel would mean I had 4 inverters with two of them on L1 and two of them on L2. Under such conditions, I would understand the need for wires to be cut to the same length.
The reason I'm asking is because if the cable lengths of both phases (L1 and L2) have to be the same length, then I need to coil up some wire in a box somewhere. Since each inverter is operating on its own line (one inverter on L1, the other on L2) and since L1 and L2 will probably never ever see a balanced load, I can't imagine why I would need the wires to be the same length.
Just thought I'd check to see if my reasoning is correct.
