Sigen Battery 9 kWh module

No. The Sigen Battery needs a Sigen Energy Controller to operate. The module is one part of a SigenStor stack: the Energy Controller is the inverter, battery management and energy management in one unit, and the battery will not run without it. A Sigen Energy Gateway is added when you want blackout protection. This is worth understanding before comparing headline prices against an all-in-one battery, because the quoted battery module is not the whole system. The [SigenStor datasheet](/media/2024/05/Datasheet-SigenStor-Home.pdf) shows how the parts fit together.

9kWh per module, up to 52kWh usable in a single tower. You start at 9kWh and add modules as your needs change, which suits a household that expects to add an electric vehicle or a pool later. For rebate purposes the size past a point stops mattering: the WA Residential Battery Scheme caps at $1,300 for Synergy customers, reached at 10kWh usable, and the federal Cheaper Home Batteries Program pays its full STC factor only on the first 14kWh, then tapers. Past roughly 14kWh you are buying capacity on its merits, not for the rebate.

It covers three single-phase Energy Controller models, not the battery modules. Sigenergy issued a voluntary recall on its 8kW, 10kW and 12kW single-phase Energy Controllers after isolated reports of damaged AC plugs. The cause was traced to installation practice rather than a cell or product defect: the original plug design needed ferrules and crimping, and those steps were sometimes skipped. Sigenergy redesigned the plug, pushed a firmware update, and is replacing affected inverters free of charge with a two-year warranty extension. We would rather you read the detail than the headline, so here is [the full account and the next steps](/learn/sigenergy-voluntary-product-recall-australia).

Bidirectional DC vehicle charging, from the same stack. Adding the [Sigen EV DC Charging Module](/product/sigen-ev-dc-charging-module) gives the system vehicle-to-home capability, so a compatible car becomes a second battery during an outage. That is a genuine capability difference rather than a specification one, and it is the main reason a household picks this platform over a sealed all-in-one. Our review of the platform is in [SigenStor defines a new digital battery era](/learn/sigenstor-by-sigenergy-defines-a-new-digital-battery-era).

10 years on the battery, installed by a Sigenergy Gold Certified Installer. PSW Energy holds Sigenergy Gold Certified Installer status in WA, and the installation and service cover runs alongside the manufacturer term. The claim conditions are in the [SigenStor warranty document](/media/2025/10/Sigenergy-SigenStor-warranty-Australia-20251006.pdf). Installation is by a WA licensed electrical contractor with SAA accredited installers, and [PSW Life Support](/psw-life-support) covers the years after commissioning.
