SUNGROW - SH4.0RS V13 Inverter

The Sungrow SH4.0RS hybrid inverter is a 4 kVA single-phase transformerless inverter , positioned as the mid-range option in the SH RS residential range. Compact and lightweight (18.5 kg), it is designed for installers working on new or renovated residential projects where the combined management of PV production, storage, and grid connection is the primary objective.

Its two independent MPPT trackers , with one string per MPPT and a recommended input PV power of 11,000 Wp These units cover standard residential rooftop configurations. The maximum DC input voltage is 600 V, with an MPP range of 40 V to 560 V. Native compatibility with the Sungrow SBS050 battery makes it a consistent solution for projects incorporating storage from the Sungrow range, with simplified commissioning.

Storage management relies on a wide battery voltage range of 80 V to 460 V , compatible with most Li-ion batteries on the market. Charge and discharge current reaches 30 A, with a maximum charge/discharge power of 6,600 W. Intelligent zero-PID control is integrated as standard.

The transition to backup mode occurs in less than 10 ms , without any perceptible interruption. In off-grid mode, the peak output power reaches 8,400 VA for 10 seconds to absorb current surges when equipment starts up. The integrated EMS with advanced customization allows the energy management strategy to be adapted to the household's consumption profile.

Natural convection cooling ensures quiet operation (less than 45 dB(A)), with no moving mechanical parts, making it suitable for installation in living spaces or habitable volumes. Monitoring is provided via the iSolarCloud platform, accessible through a mobile app and web interface, with real-time data updates every 10 seconds and online IV curve analysis.
