SMA Sunny Tripower Smart Energy STP6.0-3SE-40 Hybrid Inverter 6 kW Three-Phase
The SMA Sunny Tripower Smart Energy STP6.0-3SE-40 is a 6 kW three-phase hybrid inverter with 2 MPPT trackers and a photovoltaic array of up to 9,000 Wp. It brings together a photovoltaic inverter and a battery inverter in a single unit, with high-voltage (150-600 V) storage, 30 A maximum current, charging power up to 9,000 W and discharging power up to 7,200 W.
In the event of a blackout the three-phase backup function delivers 6,000 W rated with a peak of up to 7,200 W and switchover of less than 50 ms. Cooling is passive by convection (30 dB(A)) and the protection rating is IP65. Connectivity includes Wi-Fi, two Ethernet ports and CAN for the battery, with Modbus SMA/SunSpec and Speedwire/Webconnect. CEI 0-21 certified.
