Commissioning and optional energy control. CORE1 STP 50-41 includes ArcFix hardware, but the country dataset determines whether arc detection is active by default. The installer must check the selected country setup and activation; universal default activation is not established. AC/DC surge-arrester kits are optional and must be specified separately. An optional Sunny Home Manager 2.0 and SMA EV Charger 7.4/22 provide departure-time and energy-target charging through the SMA Energy App, with compatible network, metering sized for the installation and portal configuration. Conditional surplus charging depends on settings and available energy; meeting a target can draw grid power. This is accessory scheduling, not a native inverter charging port. Data Manager compatibility for EV Charger Business is monitoring-only, while the reviewed eCharger OCPP function remains in preparation; no higher OCPP or vehicle-discharge capability is credited. SMA’s global CORE1 page says the series is no longer marketed and identifies Sunny Tripower X 60 as its successor, while operating documentation remains available. This does not establish a retirement date, local stock status or cessation of warranty support. Existing Australian and Indian availability records remain unchanged. With an optional Sunny Home Manager 2.0 and compatible potential-free relay (or compatible socket plus a separate relay), an SG Ready heat pump can receive a surplus-solar switch-on recommendation. The heat pump remains permanently powered; its configured operating mode determines the response. Installation requires compatible hardware, metering, automatic data requests and configured load windows, power and minimum on/off times. This is optional relay control, not a native CORE1 heat-pump port or variable compressor-speed control. Source 1.Source 2.Source 3.Source 4.Source 5.Source 6.Source 7.Source 8.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Strong evidence coverage

27 of 27 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them.
