Sigenergy SigenStor Specs: Sizes, Warranty and Datasheets (2026)

This is the one-page specification reference for the Sigenergy SigenStor in Australia: the single-phase SP and three-phase TP variants, the 2026 Neo modules, warranty throughput, and the physical numbers that matter when you are sizing a system. For the full verdict and the November 2025 recall detail, see our Sigenergy SigenStor review; for pricing, the Sigenergy price list.

SigenStor SP vs TP: core specs

The SigenStor is an all-in-one tower: a hybrid inverter (the energy controller), stackable LFP battery modules, an optional backup gateway, and an optional DC EV charger. The two mainstream variants differ mainly in phase and output.

Spec	SigenStor SP 16	SigenStor TP 16
Phase	Single-phase	Three-phase
Usable capacity	15.6 kWh	15.6 kWh
Continuous power	5 kW	10 kW
Peak power	10 kW	15 kW
Coupling	AC + DC	AC + DC
Chemistry	LFP	LFP
IP rating	IP66	IP66
Modular	Yes	Yes
V2H ready	Optional	Optional
Warranty	10 years	10 years
Affected by 2025 recall	Some units	No

The IP66 rating (full dust protection plus resistance to powerful water jets) is a step above the IP55 of many rivals for exposed coastal or tropical installs. AC + DC coupling means the SigenStor suits both retrofits onto existing solar and new solar-plus-battery builds, covered in our Sigenergy retrofit guide.

Battery modules and tower capacity

You reach your target capacity by stacking modules on a single energy controller. Two module families exist in 2026.

Module	Size	Depth of discharge	Notes
Original block	5 kWh	High	Entry building block
Original block	8 kWh	High	Better value per kWh than the 5kWh
Neo module (2026)	6.0 kWh	100%	314Ah cells, up to 10,000 cycles
Neo module (2026)	10.0 kWh	100%	314Ah cells, up to 10,000 cycles

• Single-tower range: about 8 kWh up to 48 kWh of usable capacity.
• With the DC EV charger module fitted: maximum battery capacity in that tower is 40 kWh.
• Per-module optimisers: each module manages itself, so you can mix modules of different ages in one stack without dropping to the weakest module's level.

Warranty and throughput

The SigenStor battery and energy controller carry a 10-year warranty to at least 70 percent capacity retention, or a defined energy throughput, whichever comes first.

Component	Warranty	Throughput allowance
5 kWh battery module	10 years / 70%	~15.85 MWh
8 kWh battery module	10 years / 70%	~23.77 MWh
Energy controller	10 years	–
EV charger module	3 years	–
Accessories	2 years	–

For a household cycling once a day, the 10-year time limit is the binding constraint rather than throughput, so most owners will not reach the energy cap.

Optional modules

• Backup gateway: disconnects your home from the grid in a blackout so the battery can keep running (about $890 to $1,990). See the backup gateway explained.
• DC EV charger: a 25kW bidirectional module (around $6,000) that fast-charges an EV and supports vehicle-to-home. See the Sigenergy EV charger review.
• AI energy management: weather-aware dispatch through the mySigen app, standard across the range.

Which variant for your home

• Single-phase home: the SP 16 (or a smaller SP stack). Confirm the controller has the updated AC connector from the 2025 recall remedy.
• Three-phase home: the TP, for 10kW output and balanced three-phase backup; not affected by the recall.
