Using an alternative cable is not covered by Enphase's compatibility documentation. If you require an alternative for a specific project, consult your Enphase distributor — but the Belcom FireFighter 430 Series is the safe, warranted choice for standard UK installations.\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n  \u003cdetails style=\"border:1px solid #008377; border-radius:6px; margin-bottom:10px;\"\u003e\n    \u003csummary style=\"background:#008377CF; color:#fff; padding:12px 16px; cursor:pointer; font-weight:bold; border-radius:5px;\"\u003eWhat does LSZH mean and why does it matter for a home installation?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;\"\u003e\n      \u003cstrong\u003eLSZH (Low Smoke Zero Halogen)\u003c\/strong\u003e means the cable jacket is formulated to produce minimal smoke and \u003cstrong\u003eno halogen gases\u003c\/strong\u003e if it catches fire. Standard PVC-jacketed cable releases toxic hydrogen chloride gas during combustion, which can be lethal and corrosive to electrical equipment.

The CTRL cable connects the IQ Battery 5P to the \u003cstrong\u003eEnphase Communications Kit 2 INT\u003c\/strong\u003e, which enables wired communication between the IQ Gateway Metered and the IQ Battery 5P.
