color: #444; font-size: 0.93em; line-height: 1.7;\"\u003eNo — the KH7 is designed to work exclusively with \u003cstrong\u003eFox ESS high-voltage lithium-ion batteries\u003c\/strong\u003e: the ECS series (ECS2900, ECS4100, ECS4300, ECS4800), the HV2600, MIRA HV25, and EP series. Up to seven battery modules can be connected in series, giving a maximum storage capacity of \u003cstrong\u003e33.24 kWh\u003c\/strong\u003e.

The KH7 includes a built-in \u003cstrong\u003eEPS (Emergency Power Supply)\u003c\/strong\u003e function that automatically switches to battery power when grid loss is detected. The switchover occurs in \u003cstrong\u003eunder 6 milliseconds\u003c\/strong\u003e — fast enough to maintain most sensitive loads without interruption. EPS output is the full \u003cstrong\u003e7 kVA continuous\u003c\/strong\u003e, with a \u003cstrong\u003e14 kW, 60-second peak\u003c\/strong\u003e to handle motor and compressor start-up currents.

The KH7 is a \u003cstrong\u003eDC-coupled hybrid inverter\u003c\/strong\u003e — it accepts solar panels on its own MPPT inputs and replaces the existing inverter. It is \u003cstrong\u003enot an AC-coupled device\u003c\/strong\u003e. If you wish to add battery storage without replacing a working inverter, the \u003cstrong\u003eFox ESS KA7\u003c\/strong\u003e (AC Coupled Inverter) is the appropriate product from the same K-Series family, as it connects on the AC bus alongside an existing string inverter.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"background: #ffffff; border-bottom: 1px solid #e8e8e8;\"\u003e\n\u003csummary style=\"background: #008377CF; color: #ffffff; padding: 12px 16px; font-weight: 600; cursor: pointer; list-style: none; font-size: 0.97em;\"\u003eWhat monitoring is included, and do I need a separate data logger?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px; color: #444; font-size: 0.93em; line-height: 1.7;\"\u003eThe KH7 comes with a \u003cstrong\u003eWiFi dongle\u003c\/strong\u003e in the box, giving immediate access to the \u003cstrong\u003eFoxCloud V2.0\u003c\/strong\u003e platform — no separate data logger is needed.

A \u003cstrong\u003eCT clamp\u003c\/strong\u003e is supplied for grid monitoring; a Modbus energy meter is recommended when the cable run between the inverter and grid supply exceeds 30 metres.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"background: #f7fafa; border-bottom: 1px solid #e8e8e8;\"\u003e\n\u003csummary style=\"background: #008377CF; color: #ffffff; padding: 12px 16px; font-weight: 600; cursor: pointer; list-style: none; font-size: 0.97em;\"\u003eDoes the KH7 qualify for Smart Export Guarantee (SEG) payments?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px; color: #444; font-size: 0.93em; line-height: 1.7;\"\u003eYes — provided the installation is carried out by an \u003cstrong\u003eMCS-certified installer\u003c\/strong\u003e and the system is registered on the MCS database.
