Built for serious backup and EV charging. Ready for heavy loads, backup power, and smart energy setup that looks good too.
Summary
This Ballarat project shows where residential energy systems are heading. The install combines a 25kW three-phase Sigenergy inverter, four battery modules, 30kW of solar and a 25kW DC EV charger in one clean garage-based setup. Instead of treating solar, storage, backup and EV charging as separate systems, this platform brings them together in a single DC-coupled architecture designed for higher-demand homes that want real backup performance and future-ready charging capability.
Serious Sigenergy residential setup in Ballarat
A 25kW three-phase inverter, four stacked battery modules, 30kW of solar, and a 25kW DC EV charger, all installed neatly in the garage and fully commissioned for day-one use.
The hardware stands out here with max capability packed into one system. Sigenergy’s platform is built as an integrated home energy system, combining inverter, battery storage, energy management and the DC EV charging in the one architecture. Rather than stitching multiple brands together you get one coordinated system.
It covers solar production, home backup and EV charging, all in one – a big advantage when the loads are high and reliability matters. It also opens the door to vehicle-to-home backup, where the EV can act as another battery reserve for the house when that capability is enabled.
The 25kW three-phase inverter puts this well beyond a light-duty home battery install.
It’s sized for a property that wants to run without tiptoing around power use.
Three-phase capacity becomes important if you’ve got a larger household loads or workshop circuits. On the solar side, 30kW of panels gives the system strong daytime generation to run the house, refill storage and support EV charging.
We installed Sigenergy’s official three-phase 25kW model, and its DC EV charging module which supports up to 25kW bidirectional charging with direct DC-coupled charging from solar. Sigenergy’s battery modules are available in 5.38kWh and 8.06kWh sizes and stack in a modular format.
The system was fast to commission by our friends at SMA Electrical. It was installed clean and compact in the garage. The stackable installation and a DC-coupled design kept PV, storage and EV charging all in the same energy path. The home owners have less system clutter, a neater install, and a setup that feels like purpose-built infrastructure, plus it looks good.
