We took a closer look at the three-phase version of the Sigenergy SigenStor to explain how it differs from the standard single-phase setup – and what it means for homeowners with a three-phase supply or commercial clients looking for serious storage capacity.
In this video, we cover the different inverter ratings available – from 5kW all the way up to 25kW – and the increased MPPT flexibility that gives you more options when designing your solar system. We also explain how the system can scale up to 2.4MWh of storage, and break down the full range of three-phase gateways, from the Home Max to commercial units capable of delivering up to 1.2 megawatts of output.
If you’re planning a larger installation – whether for a three-phase home, estate, or commercial property – this video will help you understand what the three-phase SigenStor can do, and why it might be the right solution for your energy needs.
