Sigenergy SigenStor. Five systems, one.

The Sigenergy SigenStor is called a 5-in-1 system because it combines five functions that Australian homes usually buy as separate products into one modular stack — a hybrid solar inverter, an LFP battery, the battery power conversion system (PCS), an optional bi-directional EV DC charger and an AI-driven energy management system. In a conventional setup, each of these is its own wall-mounted box wired together on install day, which means more cabling, more brands to warrant and more points of failure. SigenStor instead delivers generation, storage, EV charging and optimisation as a single integrated unit that shares one control platform. For an Australian household, that means the same hardware can capture rooftop solar, store it for evening use, feed a compatible EV and shift energy around time-of-use tariffs, with less clutter on the wall and one system to manage rather than several.

A SigenStor is built from safe, long-life LFP (lithium iron phosphate) battery modules of 5kWh or 8kWh each, so you size storage to your actual usage rather than a fixed block. You can stack up to six modules for as much as 48kWh per stack, and parallel multiple stacks together for larger homes or small businesses that need more capacity. On the power side, inverter models range from around 5kW single-phase, which suits most suburban Australian homes, up to 25kW three-phase for bigger properties or three-phase supply. The optional EV DC charger adds fast charging at up to 12.5kW or 25kW. Because storage, inverter power and EV charging all scale independently, a household can start with a modest configuration and add modules later as budget, an EV purchase or higher energy needs arrive, without replacing the core system.

Yes, the Sigenergy SigenStor is covered by a substantial warranty package. Sigenergy provides a 10-year product warranty on the battery, and the system is warranted to retain at least 70% of its usable capacity at year 10 — so it should still hold a meaningful share of its original storage a decade in, not just remain functional. The gateway carries a 5-year warranty that can be extended, and optional modules such as the EV charger are covered under their own manufacturer terms. For Australian buyers, these manufacturer warranties sit alongside your rights under Australian Consumer Law, which apply regardless of what a warranty states. It's a modern, well-backed package from a fast-growing premium brand, and Mission Green handles the installation so the workmanship and the equipment warranties are clearly accounted for.
