Sigenergy SigenStor EC 3.0 SP Hybrid Inverter 3 kW Single-Phase
The SigenStor EC 3.0 SP is the inverter unit (Energy Controller) of the modular SigenStor system in the 3 kW single-phase version. It integrates photovoltaic inverter, battery inverter and energy management in a single body and stacks with the SigenStor BAT battery modules (1 to 6 modules per controller, battery voltage 300-600 V).
It accepts up to 6,000 W of photovoltaic power across 2 MPPTs, with a maximum DC voltage of 600 V and an MPPT range of 50-550 V: a configuration suited to small residential systems. Maximum efficiency is 98.0%, backup switchover is 0 ms and off-grid peak power reaches 2 times the rated value for 10 seconds. Natural convection cooling (silent operation) and IP66 protection rating.
Key features
Modular SigenStor systemFrom 1 to 6 SigenStor BAT battery modules stackable beneath the Energy Controller: storage can be expanded over time without changing the inverter.
Silent operationNatural convection cooling, with no fans: also suitable for installations close to residential areas.
0 ms backupThe backup switch changes over in 0 ms and off-grid peak power reaches twice the rated value for 10 seconds.
2 MPPT trackersTwo MPPTs with 16 A per tracker and a 50-550 V range make it possible to manage two roof pitches with different orientations.
Outdoor installationIP66 protection rating and operating temperature from -30 to +60 °C.
Built-in monitoringWi-Fi, Fast Ethernet and RS485 as standard; 4G/3G/2G connectivity with the optional Sigen CommMod module.
