8 kW Single-Phase Battery Solar Inverter SMA Sunny Island 8.0H

The SMA Sunny Island 8.0H single-phase inverter (ref. SI8.0H-13) is a robust, efficient, and versatile solution for energy management in self-consumption systems, off-grid installations, or backup systems. With a nominal power of 6,000 W and an overload capacity of up to 11,000 W for 3 seconds, this model ensures a stable supply even during demand peaks.

The Sunny Island 8.0H is part of the SMA Flexible Storage system, allowing temporary storage of solar energy generated for use at any time of the day. It is compatible with lithium-ion, FLA, and VRLA batteries, operating at 48 V and offering charging and discharging currents of up to 140 A and 136 A respectively.

Its quick and easy commissioning is thanks to the integrated web interface and standard connectivity via LAN and WLAN, allowing configuration and monitoring from any smartphone, tablet, or laptop. Additionally, it is compatible with the Sunny Portal powered by ennexOS system, facilitating precise and detailed monitoring of the energy system.

With a maximum efficiency of 95.8% and a standby consumption of only 6.5 W, this inverter guarantees high energy efficiency. It features advanced functions such as soft start, automatic rotating field detection, multifunction relay, and the ability to operate in three-phase configurations via cluster connection.

The IP54 protection and its operating temperature range between -25 °C and +60 °C allow for outdoor installation and in demanding weather conditions. Additionally, SMA offers a 5-year warranty extendable to 10 years at no additional cost, reinforcing its commitment to product reliability and durability.
