Sigenergy SigenStor EC 17.0 TP Hybrid Inverter 17 kW Three-Phase
The SigenStor EC 17.0 TP is the inverter unit (Energy Controller) of Sigenergy's modular SigenStor system: a three-phase hybrid inverter of 17 kW that combines photovoltaic inverter, battery inverter and energy management in a single body. It stacks with the SigenStor BAT battery modules (1 to 6 modules per controller, battery string voltage 600-900 V) to form a compact tower for wall or floor mounting.
On the photovoltaic side it accepts up to 27,200 W of PV power with 4 MPPTs, a maximum DC voltage of 1,100 V and an MPPT range of 160-1,000 V, which makes it suitable for residential and small-business systems with long strings or several orientations. Maximum efficiency is 98.3%, backup switchover takes 0 ms and off-grid peak power reaches 2 times the rated value for 10 seconds. IP66 protection rating and intelligent air cooling also allow outdoor installation.
