Product Description

Solar Inverter for commercial and large home PV systems

The new Sunny Tripower X 12 is the innovative system solution for commercial and large home PV systems. The integrated System Manager function with direct access to Sunny Portal powered by ennexOS monitors up to five SMA inverters and one energy meter. This enables the dynamic closed-loop control of active and reactive power via SMA Dynamic Power Control. Thanks to the wide input voltage range and the high input current capability, it is compatible with the latest generation of high-performance PV modules. The innovative enclosure design ensures efficient cooling of the electronic components and thus guarantees maximum lifetime of the Sunny Tripower X 12.
Commissioning can be performed quickly and easily as well as centrally for all devices in the system. During operation, users benefit from integrated software solutions: SMA ShadeFix increases PV yields even in the event of partial shading. SMA ArcFix detects electric arcs effectively and can reliably reduce the risk of fire.
