Our read of the datasheet
The SigenStor EC 6.0 SP is the 6 kW single-phase energy controller that sits on a SigenStor battery stack. It takes 12 kW of PV, a 2.0 DC/AC ratio, on two MPPTs. The single-phase range runs from 5 kW to 12 kW, with the 8 kW and larger models adding a third or fourth MPPT.
Backup output is 6 kW, with a 9 kW peak for 10 seconds. The zero-millisecond switchover figure applies only when a Sigen Energy Gateway is installed with the controller and battery, so include it in the quote if you want uninterrupted backup. The controller takes one to six SigenStor BAT 5.0 or 8.0 modules.
Peak efficiency is 98.0% and European efficiency 97.4%. Sigenergy's Australian warranty covers the Energy Controller for 10 years, but the warranty document says the full term may not be honoured if the system stays offline for an extended period, with five years always provided.
We have not tested this inverter. This summary follows from the manufacturer's published specifications, checked 23 September 2026.
