# Sigenergy Battery Systems in Townsville

Barra Solar Power installs Sigenergy batteries in Townsville and across North Queensland.
We design and fit Sigenergy home battery systems for local homes, starting with 
how your household actually uses power: [your existing solar](https://www.barrasolarpower.com.au/add-battery-to-existing-solar/),
your switchboard, single or three phase supply, and what you want the battery to
do. Then we design a system to suit.

Sigenergy’s SigenStor is a modular system. The energy controller, battery modules
and optional EV charging stack together into one unit, so a system can start at 
a size that makes sense now and grow later. Our local team handles the design, the
installation and the paperwork, and we’re here for support after the job is done.**
Our team of Sigenergy-trained electricians** designs, installs and supports every
system.

## The Sigenergy home energy range

Sigenergy makes a connected set of products that can be combined to suit the home:

### 5-in-One SigenStor

 * **SigenStor EC**: energy controller for solar plus energy storage
 * **SigenStor BAT**: modular battery (BESS)
 * **SigenStor EVDC**: bi-directional DC EV charger

### Hybrid Inverter

 * **Sigen Hybrid Inverter**: a slim wall-mounted hybrid inverter
 * **SigenStor BC**: battery controller that connects Sigen Battery modules to the
   Sigen Hybrid Inverter

### Energy Gateway & chargers

 * **Sigen Gateway**: the home energy hub, used for backup switching
 * **Sigen EVAC Charger**: AC EV charger
 * **SigenMicro Inverter**: microinverter for rooftop solar

### App & Cloud

 * **mySigen App**: monitoring and energy management for homeowners
 * **Sigen Cloud**: Sigenergy’s platform for device lifecycle management

## SigenStor Energy Controller

The Sigen Energy Controller (SigenStor EC) is the core of a SigenStor system. It
manages solar, battery and household loads together.

 * **5.0–12.0 kW** single phase models and **5.0–30.0 kW** three phase models
 * Built-in energy management system (EMS) for precise control
 * Up to 2.0 DC/AC ratio on single phase models, so more solar panels can be connected
   relative to inverter size
 * Unbalanced three-phase output on three phase models
 * 150% peak output power in off-grid mode (for 10 seconds, per Sigenergy’s datasheet)
   for appliances with a high start-up draw
 * Up to 4 MPP trackers, useful for roofs with panels facing different directions
 * Connects 1 to 6 SigenStor BAT modules (5.0 or 8.0 models) per controller
 * IP66 rated, with an operating range of −30 °C to 60 °C

07-18-at-10.53.18-am-scaled-1.jpeg "Sigenergy Battery Systems | Barra Solar Power")

## Sigen Battery (SigenStor BAT)

 * Lithium iron phosphate (LFP) cells, 280 Ah
 * Rated to 10,000 cycles*
 * 100% depth of discharge, so the full usable capacity can be used
 * Pack-level battery optimisation: modules can be mixed and matched, and the system
   upgraded later
 * Higher energy density for a compact footprint
 * Five layers of battery safety protection (below)

*Cycle figure provided by the battery cell manufacturer, based on cell test conditions
of 25 ± 2 °C, 0.5C charge and discharge rate and SOH = 60%.

## Battery safety: five layers of protection

Sigenergy builds several layers of protection into each battery module:

 1. Cell-level temperature monitoring
 2. Internal fire extinguishing kit
 3. High-temperature-resistant insulated pads
 4. Aerogel insulated pads
 5. Decompression valve

Battery status can be checked in real time in the mySigen App.

## Backup power and switching

With the right equipment, a SigenStor system can switch between energy sources (
grid, solar, battery, generator and a compatible EV) without interrupting the home.
Sigenergy specifies a **0 ms load-side disruption time** for its backup switch. 
That figure applies when a Sigen Energy Gateway is installed with the Sigen Energy
Controller and Sigen Battery, and when the controller’s nominal power is higher 
than the total load in the home at the time.

What stays on in a blackout depends on how the system is configured: which circuits
are backed up, the size of the battery and inverter, and the state of charge when
the grid goes down. We’ll talk this through with you during design.

## Sigen Hybrid Inverter

![White Sigenergy hybrid inverter with a slim profile](https://www.barrasolarpower.
com.au/wp-content/uploads/2026/09/sigen-hybrid-inverter-1.jpg "Sigenergy Battery
Systems | Barra Solar Power")

For homes that suit a wall-mounted inverter, the Sigen Hybrid Inverter connects 
to Sigen Battery modules through the SigenStor BC battery controller.

 * 99 mm ultra-slim design
 * 25 dB operating noise
 * IP66 rated, with an operating range of −30 °C to 60 °C
 * Up to 99.0% maximum efficiency
 * 200% peak output power while off-grid (three phase models, 10 seconds)
 * 200% DC/AC ratio for higher solar yield

## EV charging: SigenStor EVDC

The Sigen EV DC Charging Module is part of the SigenStor stack, so the battery system
and a DC EV charger share one unit.

 * 25 kW bi-directional DC charging
 * 150–1000 V charging voltage range
 * IP66 rated
 * Can charge your EV from your own solar
 * V2X-integrated: Sigenergy describes it as the world’s first V2X-integrated all-
   in-one home energy system. V2X depends on the vehicle’s own capabilities, so 
   we’ll check your EV before you rely on it.

An AC option, the Sigen EVAC Charger, is also available.

¹ Load-side disruption time. Requires a Sigen Energy Gateway used together with 
the Sigen Energy Controller and Sigen Battery. Test conditions: grid in open-circuit
state, with the controller’s nominal power higher than the total power of the home
loads.
² Optional feature, only supported on certain models.³ Sigenergy publishes
the full certificate list on its website.Source: Sigenergy, Sigen Energy Controller
datasheet (Australia), version 20251107. Specifications can change, so we confirm
the current datasheet for your chosen model in your quote.

## Warranty

Sigenergy’s product warranty terms for your chosen controller, battery modules and
accessories are set out in your quote. Our installation work is backed by Barra 
Solar Power’s 10-year workmanship guarantee.

## Is Sigenergy right for your home?

Sigenergy is often a good fit if you:

 *     want a battery system you can expand later by adding modules
 *     have, or plan to add, a reasonable amount of solar and want to use more of
   it at night
 *     are thinking about an EV now or down the track, and like the idea of DC charging
   built into the same system
 *     want clear monitoring and control from an app
 *     have single or three phase power (there are controller models for both)

It may not be the best choice for every home. Space, switchboard condition, existing
inverters, your supply type and your budget all come into it. If another brand suits
you better, we’ll say so. We also install Tesla Powerwall 3, Sungrow and SolaX, 
and BYD on some existing systems. See all our [battery systems](https://www.barrasolarpower.com.au/battery-systems/).

Frequently asked questions

## Sigenergy FAQs

01Can I add more battery capacity later?

Yes, within limits. Each Sigen Energy Controller supports 1 to 6 SigenStor BAT modules(
5.0, 8.0 or 10.0 models). If you expect your usage to grow, for example with an 
EV or a pool, we can plan for that in the initial design.

02Will a Sigenergy battery keep my power on in a blackout?

It can, for a Townsville blackout, when the system is set up for backup. Seamless
switching needs a Sigen Energy Gateway. We do not promise whole-home backup by default—
what stays on depends on which circuits are backed up, inverter size and battery
charge. We'll explain what's realistic for your home before you decide. More on 
[will a home battery work during a Townsville blackout](https://www.barrasolarpower.com.au/battery-systems/#blackout-backup).

03Do I need single phase or three phase?

That's set by your home's electricity supply. Sigenergy makes single phase controllers
from 5.0 to 12.0 kW and three phase controllers from 5.0 to 30.0 kW. We check your
supply and switchboard as part of the site assessment.

04Will it work on the Ergon Energy network?

Yes. Ergon must approve it before we connect it, even if it won't export. On a single-
phase home, the SigenStor's inverter counts toward Ergon's 10 kVA limit, and export
is usually capped at 5 kW per phase on a basic connection. Read more about [solar and batteries on Ergon in Townsville](https://www.barrasolarpower.com.au/ergon-solar-townsville/).
