Sigenergy is the battery system we recommend most. SigenStor is a modular, all-in-one battery and hybrid inverter built around Sigenergy's own smart energy controller.
SigenStor pairs a Sigen Energy Controller (the inverter and brains of the system) with one or more stackable Sigen Battery modules — the controller manages solar, battery and grid in real time through a built-in energy management system.
One energy controller runs the solar, battery, backup and (if you want it) EV charging as a single system, instead of several separate boxes talking to each other. It's tidy to install, easy to live with through the mySigen app, and it's what Tom and Joy from Ludicrous Feed had us put in for their 40kWh setup. Want the whole house to stay on in a blackout? Add the Sigenergy backup gateway.
For most Sydney homes on a single-phase supply — the Energy Controller and battery modules scale to the household's usage.
For larger homes on a three-phase supply, or bigger loads like EV charging, heat pumps and larger air conditioning.
Sigenergy models are CEC-approved on a model-by-model basis — we confirm the exact configuration and current CEC/STC eligibility on site. We don't put prices online. Every job is quoted in person, on site.
