What it covers
Panel side: same two-array layout as System 5, each array under its controller’s 100 V limit and 440 W rating at 12 V. AC side: the Xantrex inverter is sized for light loads. Larger loads need a bigger inverter, which this list does not include. A five battery bank also needs fusing and cable sized for it, which are not in this list.
The parts list is checked against manufacturer ratings. It is not an engineered design, a permitted installation or a promise of runtime. Cable, mounts and the fuses that go in the fuse blocks are not in this list.
