Sigenergy SigenStor EC 3.6 SP hybrid inverter

SigenStor EC 3.6 SP is a hybrid inverter designed for single-phase installations, combining operation with PV and batteries. This model offers a rated output power of 3680 W and supports input voltage up to 600 V, allowing flexible adaptation to different PV arrays. The device has a built-in energy management system (EMS) which optimises the use of generated energy.

The inverter enables off-grid operation with a short-term peak up to 150% of rated power, providing immediate power reserve for demanding loads. SigenStor EC 3.6 SP supports multiple MPPT (3 MPPT trackers in this model) for better extraction of energy from PV modules and communication via WLAN, Ethernet and RS485. The design is adapted to harsh conditions (IP66 protection rating).
