Sigenergy SigenStor EC 25.0 TP Hybrid Inverter 25 kW Three-Phase
The SigenStor EC 25.0 TP is the inverter unit (Energy Controller) of Sigenergy's modular SigenStor system: a three-phase hybrid inverter of 25 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 40,000 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.
Key features
Modular SigenStor systemThe Energy Controller pairs with 1 to 6 stackable SigenStor BAT battery modules, so storage can be sized over time without replacing the inverter.
Uninterrupted backupThe changeover time of the backup switch is 0 ms and off-grid peak power reaches twice the rated value for 10 seconds.
4 MPPT trackersWith 4 MPPTs, 16 A per tracker and a 160-1,000 V range, roof sections with different orientations and tilts are easily managed.
High efficiencyMaximum efficiency 98.3% and European efficiency 98% on the photovoltaic-to-grid conversion.
Outdoor installationIP66 protection rating, intelligent air cooling and operating temperature from -30 to +60 °C.
Integrated monitoringWi-Fi, Fast Ethernet and RS485 as standard; 4G/3G/2G connectivity available with the optional Sigen CommMod module.
