For wider layouts
The 4-metre parallel bus cable for EZ1 microinverters — the longer of the two options, for arrays where the units are not sitting side by side.
When the extra length earns its place
Four metres covers the layouts that two will not: modules split across a wide balcony, an L-shaped railing, a pair of frames either side of a doorway, or a small ground mount where the rows are separated by a walkway. It also covers the common case where the inverters end up further apart than the drawing suggested, because the mounting points that actually existed were not where you hoped.
The general rule on cable length
Buy the length you need plus a service loop, and do not buy a run so long that you are managing a coil of surplus. Excess cable on an outdoor array is not free — it needs securing, it collects water in the loop, and it gives wind something to work at over the years. That said, if you are genuinely between the two lengths, take the longer one. A short cable is a failed installation; a long one is ten minutes with cable ties.
Before you order
Measure the routed path around the frame rather than the direct distance, and add slack at each connector. Check the branch circuit rating too — how many EZ1 units you can parallel is set by the circuit feeding them, not by the cable joining them. See when you need a dedicated circuit.
Compatible with EZ1-series microinverters, including the EZ1-LV Plug-In Solar Kit and the EZ1-LV Add-On Microinverter. Also available in 2m.
