Flagship Sigenergy products we install

The Sigenergy line-up is modular — three core components that slot together into the configuration your home actually needs.

SigenStor EC (Hybrid Inverter + Battery Stack)

5 / 8 / 10 kW single-phase · 5–48 kWh modular LFP

The heart of the system. Hybrid inverter and battery modules stack vertically as one unit — start with one battery module and add more as budget or demand grows. This is what most of our Sigenergy customers install.

SigenStor DC EV Charger

Up to 25 kW DC bi-directional · V2X-ready

Directly DC-coupled to the SigenStor — no AC conversion losses when charging your EV from solar. V2X-ready firmware means your car can one day power your house during peak tariffs or grid outages.

Gateway & mySigen App

0 ms backup switchover · AI energy optimisation

The Sigen Gateway provides whole-home backup with genuinely seamless switchover. The app handles scheduling, tariff optimisation, remote diagnostics, and software updates — we've yet to meet a customer who's found it lacking.
