Without a smart divert switch, this excess is exported to the grid at the SEG rate (typically 3 – 15p\/kWh).

The Ogemray SW40 is rated for exactly 25A, which means a 6kW dual-element immersion is at the device’s maximum rated current. This is within specification, but it is good practice to keep continuous loads below 80 % of a relay’s rated capacity for longevity. For a 6kW immersion running continuously for extended periods, a 32A-rated alternative may be more appropriate. For a standard single-element 3kW immersion (13A draw), the SW40 has substantial headroom and is an ideal match.\u003c\/div\u003e\u003c\/details\u003e\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\u003cdetails\u003e\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eDoes this work with Home Assistant for solar divert without Eleven Energy?\u003c\/span\u003e\u003c\/summary\u003e\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eYes. The Ogemray SW40 integrates with Home Assistant via the \u003cstrong\u003eShelly integration\u003c\/strong\u003e (available in HACS or as a standard integration). This exposes the switch state, power reading, energy data and control as entities in Home Assistant. You can then build automation in Home Assistant to divert solar: when PV generation exceeds household consumption by a threshold amount (read from your inverter’s Modbus or API), turn on the immersion switch. This approach is popular with installers using Solis, SolaX and other inverters that expose generation data via Modbus or local API.\u003c\/div\u003e\u003c\/details\u003e\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\u003cdetails\u003e\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eDoes it work without an internet connection?\u003c\/span\u003e\u003c\/summary\u003e\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eYes.

With the switch in divert mode, you can confirm the immersion is drawing the expected 3 kW (not open-circuit or short-circuit), see cumulative kWh diverted into the hot water tank per day\/week\/month, and set overpower alerts if the immersion draws more than expected (which could indicate a wiring fault or element failure).
