The mySigen app, often searched as the Sigenergy app, is Sigenergy’s free app for monitoring and controlling SigenStor solar and battery systems. It is called “mySigen” in the Apple App Store and Google Play. As at November 2026, Australian owners normally get access when their installer registers the system with the owner’s email: Sigenergy’s cloud then sends a verification email from “sigencloud” and the owner sets a password.
This guide is independent desk research from Sigenergy’s manuals and store listings. Solar Cobber did not test the app on a live system, has no relationship with Sigenergy and was not paid. Nothing here asks you to open equipment.
Key facts
- The mySigen app is Sigenergy Technology Co., Ltd.'s free app for SigenStor and related systems, listed on the Apple App Store (version 4.2.0 dated 27 October, per the listing read in November 2026) and on Google Play.
- Sigenergy’s mySigen App User Manual (version 01, 15 September 2023) says the owner gives the installer an email address, and after setup the server sends a verification email from the “sigencloud” account to set the initial password.
- The same manual lists three operating modes: Sigen AI Mode (which it recommends), Self-Consumption Mode and Fully Fed to Grid.
- The App Store listing for mySigen says version 4.2.0 added a Free Electricity Mode in Australia.
- Sigenergy’s alarm list (version 03, 29 March 2024) groups SigenStor alarms into series: 1001 to 1026 for the inverter and grid side, 2001 to 2008 for energy storage, 3001 onward for temperature, battery voltage and grid faults, 4001 to 4004 for communication and 5001 onward for the EV charger.
How do I log in to the mySigen app?
You log in with the email your installer registered and the password you set from the “sigencloud” verification email. The manual says to give your email to the installer, wait for that email, then enter the account and password and tap “Log in”. If the email never arrives, the manual says to check junk mail for the “sigencloud” account and ask for it to be sent again.
Forgotten passwords are handled with “Forgot Password” on the login screen. We found a Plico Energy help page that points Sigenergy owners to app-aus.sigencloud.com for registration, and Sigenergy’s installer manual describes a browser version reached from the Sigenergy website under the mySigen App menu, with a Chromium-based browser recommended. We could not open Sigenergy’s own mySigen page (its site blocked our requests), so confirm the current web address with your installer.
The App Store listing says Australian and New Zealand users were moved to a local server. If an old login fails, ask your installer whether your account was migrated.
How do I set up a new SigenStor in the app?
The installer does the commissioning, and the owner then adds preferences such as operating mode and backup reserve. Sigenergy publishes a separate installer manual for the app, and the owner manual contains no step for creating a system yourself.
The owner-side steps in the manual are short:
- Give your installer an email address you can access.
- Set your password from the “sigencloud” email and log in.
- Check the Home screen and Device screen show your equipment.
- Choose an operating mode (Home, then Mode, or Setting, then Operational Mode).
- If you have a Sigen Energy Gateway, set a backup reserve under Setting, then Backup Reserve.
What internet connection does the system need?
The manual recommends Ethernet and advises against changing network type when the network is stable or joining an unencrypted wireless network. An Australian distributor (SolarHub) says the system needs a 2.4 GHz Wi-Fi network, as a 5 GHz-only connection will not work.
The SolarHub steps for rejoining Wi-Fi involve removing the unit’s covers to reach a QR code. We do not recommend that: ask your installer or support provider to reconnect it. Connectivity matters because the review of the Sigenergy SigenStor notes the warranty requires the system to stay online, and cover drops to five years if it is offline for over a year.
How do I read the mySigen dashboard?
The Home screen shows the station’s status (diagnosis, notices, current mode, safety and lighting), and the Device screen lists each connected device. The terms below are the ones owners most often misread.
| Term | What it means | Where to watch for trouble |
|---|---|---|
| Solar (PV) power | Power from the panels right now, in kW | Zero on a clear day suggests a fault |
| Load or consumption | What the home is using | Includes backed-up and non-backed-up circuits only if the meter sees them |
| Grid import | Power bought from the grid | High at night is normal with a small battery |
| Grid export | Power sold to the grid | Capped if an export limit is set |
| Battery state of charge (SOC) | Percentage of usable battery energy | Stops falling at your backup reserve |
| Backup reserve | SOC kept for blackouts (needs a Gateway) | Raising it lowers daily savings |
| Self-consumption | Share of solar used at home | Rises with a battery |
Table: dashboard terms, based on Sigenergy’s mySigen App User Manual (version 01, September 2023) and general usage. Screens differ by app version.
What are the mySigen operating modes, and what is Sigen AI mode?
Sigen AI Mode learns your consumption pattern and local electricity prices over a period and builds a plan to maximise savings, according to Sigenergy’s manual. The manual recommends it, but it is Sigenergy’s own description and we found no independent test of the savings.
| Mode | What Sigenergy’s manual says | Suits |
|---|---|---|
| Sigen AI Mode | Learns consumption peaks and troughs and local prices, then plans automatically | Owners wanting hands-off control |
| Self-Consumption Mode | Stores excess solar, and releases battery power when solar is short or at night | Flat or low export tariffs |
| Fully Fed to Grid | Maximises output sold to the grid; surplus above inverter capacity goes to the battery, and the battery discharges to keep output at maximum | Specific export arrangements |
Table: operating modes in mySigen App User Manual version 01 (15 September 2023). Newer app versions have added modes, including a Free Electricity Mode in Australia in 4.2.0.
Sigenergy’s App Store listing describes version 4.0 as adding energy forecasts, a “How System Works” view, energy strategies you describe in plain language and an AI assistant. Sigen AI Mode was extended to the EV DC charger in 4.1.x. Sigenergy’s own 3-minute video below shows the version 4.0 changes.
Sigenergy’s official channel also has a short video on setting the operating mode in the app (video id rnJoOtc-mrE, “How to set operation mode on mySigen App?”), which is about two years old and may not match the current screens.
Check your tariff before picking a mode. Time-of-use windows are covered in peak and off-peak electricity times in Australia.
Common mySigen problems and fixes
Most problems are an offline system, a stale reading or a locked-out login, and most have a safe first check. None of the steps below involve opening the controller or switchboard.
| Symptom | Likely cause | What an owner can safely do | When to call the installer |
|---|---|---|---|
| App shows system offline or no data | Home internet down, router changed, or Wi-Fi password changed | Check the router and 2.4 GHz network; allow up to 24 hours after reconnecting (SolarHub) | Still offline after your router is working |
| No verification email | Wrong address, or email in junk | Check junk folder for “sigencloud”, resend, use “Forgot Password” | Installer registered a different address |
| Cannot log in after an app update or region change | Account on another server | Reset the password, update the app | Account was never created |
| Battery will not discharge below a level | Backup reserve is set | Lower the reserve under Setting, Backup Reserve | Reserve is low yet battery stops |
| Export is lower than panels suggest | Export limit set by installer | Check Advanced Settings, Export Limitation (manual says set per local rules and grid agreement) | You need the limit changed |
| Alarm in Notice or Service | See code table | Note the code and photograph the screen | Any repeated or battery code |
| Totals look wrong | Meter or time zone setting | Compare with your retailer bill after a full month | Persistent mismatch |
Table: symptoms and safe owner actions from Sigenergy’s user manual and SolarHub’s knowledge base, checked November 2026.
What do Sigenergy alarm and fault codes mean?
An alarm code is a four digit number with a fault ID, shown in the app under Home, Notice or the Service tab. Many grid codes clear on their own. The selection below is from Sigenergy’s alarm list, version 03, released 29 March 2024, and the full list is longer.
| Code | Fault | What Sigenergy says |
|---|---|---|
| 1002 | Low insulation resistance | PV string short to earth or damp; wiring check by a qualified person; may clear in dry weather |
| 1003 | Inverter over-temperature | Check ventilation and direct sun on the unit |
| 1010 | Grid power outage | Usually reconnects when the grid returns; check the AC switch is on |
| 1011 to 1014 | Grid over or under voltage and frequency | Usually reconnects; repeated faults go to the grid operator and installer |
| 1017 | Leakage current out of limit | Often transient and recovers; frequent repeats go to service |
| 1018, 1019 | Communication faults (4G or internal CAN) | Check 4G data and the dongle; otherwise service |
| 2002 | Storage module low insulation resistance | Shut down from the app, wait, restart; if it persists, service |
| 2003 | Storage over-temperature | Check ventilation and direct sun |
| 3001, 3002 | Under-temperature | Wait for ambient temperature to rise; the unit resumes itself |
| 4001 to 4004 | Gateway or meter communication faults | Check port connections and that the Gateway breaker is on, which is installer work |
Table: selected alarm codes from Sigenergy Alarm List version 03 (29 March 2024), as hosted by Current Generation (NZ). Newer firmware may differ; the app shows the current corrective text.
Several remedies involve DC or AC switches, cabling or Gateway breakers, which are work for a qualified installer, not an owner. If a code repeats, photograph it and contact your installer.
Is the mySigen app free, and how long is data kept?
The App Store and Google Play listings show the app as free. We found no published subscription fee for owners and no published data retention period or export format in the documents we could open, so ask your installer before assuming you can download history. The App Store listing says the developer does not collect data, a claim we cannot verify.
What should my Sigenergy system’s output look like?
Compare your daily solar yield with these per kilowatt figures, which let you judge a 6.6 kW or 20 kW array alike. Output is lower in winter in every capital except Darwin, so judge a month against the same month, not one cloudy day.
- Summer
- Winter
View the data as a table
| Summer | Winter | |
|---|---|---|
| Perth | 6.9 kWh | 2.6 kWh |
| Adelaide | 6.5 kWh | 2.2 kWh |
| Canberra | 6.2 kWh | 2.4 kWh |
| Melbourne | 5.9 kWh | 1.9 kWh |
| Hobart | 5.7 kWh | 1.6 kWh |
| Sydney | 5.4 kWh | 2.6 kWh |
| Brisbane | 5.4 kWh | 3.2 kWh |
| Darwin | 4.2 kWh | 4.6 kWh |
Hobart’s winter output is about 27% of its summer output, while Darwin produces more in winter than summer.
Solar Cobber calculation: multiply by your array size. A 10 kW array in Sydney should give roughly 54 kWh on an average summer day and 26 kWh on an average winter day.
Sigenergy controllers accept panels up to twice their AC rating (a DC/AC ratio of 2), according to the manufacturer datasheet summarised in our review, so a 10 kW controller can carry a larger array, and the app’s output may flatten at the controller’s limit on sunny days. That flat top is not a fault.
The Clean Energy Regulator publishes a conservative, deemed output for each postcode zone. Reading the app against it gives a floor.
Source: Clean Energy Regulator postcode zone ratings; division by 365 is a Solar Cobber calculation.
View the data as a table
| Deemed output | |
|---|---|
| Zone 1 (1.622) | 4.44 kWh |
| Zone 2 (1.536) | 4.21 kWh |
| Zone 3 (1.382) | 3.79 kWh |
| Zone 4 (1.185) | 3.25 kWh |
A system in zone 3 (including Sydney, Brisbane, Perth, Adelaide and Canberra postcodes) is deemed to produce about 3.79 kWh per kW per day, and persistent output well below that on clear days with clean panels is worth raising with your installer.
How much battery throughput does the app use up?
The mySigen app shows battery charge and discharge, and the warranty counts that energy. In the Australian warranty summarised in our review, a BAT 5.0 module has a minimum throughput of 15.84 MWh and a BAT 8.0 module 23.77 MWh, alongside the 10 year term.
View the data as a table
| Throughput per year | |
|---|---|
| BAT 5.0 | 1.58 MWh |
| BAT 8.0 | 2.38 MWh |
Solar Cobber calculation: 15,840 kWh divided by 5.2 kWh usable is about 3,046 full cycles, which is 0.83 cycles a day over 3,650 days. The BAT 8.0 works out the same (23,770 divided by 7.8 is about 3,047). A home that fully cycles its battery daily stays inside the cap, but one that also cycles for VPP events or very cheap tariffs, as AI modes may, can approach it before year 10. Watching the app’s battery totals once a year lets you spot this early. See how long solar batteries last.
Can I connect mySigen to Amber, a VPP or Home Assistant?
Yes in some cases, but only as documented by the other party. Amber has a help centre article titled “Enrolling your Sigenergy system to Amber for Batteries”, which we could not open, so check Amber’s current terms and our Amber Electric review. A retailer or VPP you authorise may override your own settings, so ask about reserve and opt-out rules; see what a VPP is.
For Home Assistant, the community project Sigenergy Local Modbus on GitHub reads the system over Modbus TCP, which the installer must switch on in the commissioning app, and its controls are read-only until you enable them. It is unofficial. Any use of a community integration alongside a retailer’s battery control should be checked with the retailer first, since two controllers can conflict.
When should I call my installer?
Call your installer for any repeated alarm, a battery or storage code, a Gateway or meter communication fault, wrong export limits, a system offline for more than a day after your internet is fixed, or any smell, noise or heat from the unit. Sigenergy recalled some 8, 10 and 12 kW single-phase controllers in November 2025, so check whether yours is affected (details in our SigenStor review).
If your installer has closed, read our tracker of solar company failures and find a local company in our installer directory. Pricing context is in our Sigenergy battery price guide, the brand overview is Sigenergy in Australia, and comparisons are in Sigenergy vs Sungrow and Tesla Powerwall 3 vs Sigenergy. For another brand’s app, see our iSolarCloud guide and Fronius Solar.web guide. Three phase owners should read single vs three phase power for solar.
FAQ
What is the mySigen app?
The mySigen app is Sigenergy’s free monitoring and control app for SigenStor solar and battery systems. It shows solar, battery, grid and home energy flow, alarms and the operating mode. It is on the Apple App Store and Google Play.
How do I log in to mySigen?
Log in with the email your installer registered and the password you set from the verification email sent by “sigencloud”. If you forgot it, tap “Forgot Password” on the login screen. If no email arrives, check junk mail and ask your installer to confirm the address.
What is Sigen AI mode?
Sigen AI Mode is Sigenergy’s automatic operating mode that learns your usage pattern and local electricity prices to plan battery charging and discharging. The manual recommends it. We found no independent savings test, so compare it with Self-Consumption on your own bills.
Why is my Sigenergy app not working or offline?
The usual cause is a lost home internet connection, often after a router or Wi-Fi password change. The system needs a 2.4 GHz network. Reconnecting may need access to the unit, so ask your installer or support provider, and allow up to 24 hours for data to catch up.
What do Sigenergy fault codes mean?
Each four digit code is an alarm in Sigenergy’s alarm list, such as 1010 for a grid outage or 2003 for storage over-temperature. Many clear when the grid or temperature recovers. Repeated insulation, storage or communication codes should go to your installer.
Can I use mySigen without a Gateway?
Yes for monitoring and modes, but backup reserve needs a Gateway. The manual says to skip the Backup Reserve setup if no Gateway is installed.
Does the mySigen app cost anything?
No fee is shown on the store listings and we found no published owner subscription. Confirm with your installer or retailer, since a VPP or retailer plan may have its own terms.
