About iStore
iStore makes home solar systems built around a hybrid inverter and a modular battery. It suits homeowners who want one brand where the parts are designed to work together. Matching backup and EV charging options can be added later.
The battery scales from 5 kWh to 60 kWh, so you can start smaller and add capacity as your use grows. Everything is managed through one app, Univers EMS. We check compatibility with your switchboard before we quote.
Which iStore product do you need?
Here’s a quick way to think about it:
- If you want to store your solar and have the option of blackout backup, the iStore Battery scales from 5 kWh to 60 kWh so you can size it to your overnight usage.
Warranty and local support
To keep the warranty valid, keep your proof of purchase, install the battery within 31 days of purchase and keep it connected to Univers EMS. Claims go through us as your installer, and we handle the paperwork with you.

Things to know before you buy
Pros
One brand covers the whole system. The inverter, battery, backup gateway and EV charger are all managed through the Univers EMS app.
The battery grows with your needs. The modular battery scales from 5 kWh to 60 kWh, so you can start smaller and add capacity later.
Long warranty terms on key parts. The inverter has a 10-year warranty and the S1 battery modules have a 15-year warranty.
Things to consider
Backup needs a separate gateway, not just a battery. An iStore battery on its own will not power your home in a blackout, so you need to add the iStore backup gateway, which powers selected essential circuits such as lighting, fridge, communications and security.
The battery only works with an iStore hybrid inverter. If your existing inverter is a different brand, adding an iStore battery usually means changing the inverter at the same time. We check this during the switchboard and compatibility assessment.
Warranty depends on monitoring staying connected. It is a condition of the battery warranty that the unit stays connected to the Univers EMS platform. If your internet drops out for long periods, you need to reconnect it, and you need to keep your proof of purchase.
Battery must be installed within 31 days of purchase. iStore requires the battery to be installed within 31 days of purchase to keep warranty terms intact. We book the install date before the hardware is ordered.
Lightning and surge damage is excluded from warranty. Damage caused by lightning or power surges is not covered. In Perth storm season, surge protection on the switchboard is worth discussing at the quote.
What an iStore installation involves
Site assessment and switchboard check
We visit the property to inspect the existing solar system, the switchboard and the space where the inverter, battery or EV charger would go. We check condition, available space and distance from the proposed equipment location, and flag any switchboard upgrade needed.
Compatibility and sizing
We confirm whether your existing inverter can run an iStore battery or whether an iStore hybrid inverter is needed, and we size the system around your actual usage pattern. If you’re planning an EV charger, we factor that in now.
Backup wiring decision
If you want blackout backup, we talk through which circuits you want kept live (typically fridge, lights, communications, a couple of power points) and quote the iStore backup gateway with the appropriate wiring.
Installation day
Our technicians mount the inverter and battery in a shaded, ventilated position, install the isolators, route the cabling between the array, inverter, battery, backup gateway and switchboard, and tidy and label everything to standard.
Network approval and commissioning
The installation is documented and connected to meet Australian standards and Western Power’s network requirements, with Synergy as the retailer. Commissioning for the battery is done to AS/NZS 5139, with charge and discharge settings configured and the monitoring connected.
App walkthrough and aftercare
Before we leave, we show you how to read the Univers EMS app and run through simple aftercare: keep the unit clear of obstructions, keep the monitoring connected (it’s a warranty condition), and book occasional health checks.
iStore Perth questions we get asked
Is iStore a good brand?
iStore is a credible choice if you want a single-vendor system where the inverter, battery, backup gateway and EV charger are designed to work together. The main thing to be aware of is that blackout backup needs a separate backup gateway, and the battery only works with a compatible iStore hybrid inverter.
How does iStore work?
An iStore hybrid inverter sits between your solar panels, your switchboard and (optionally) an iStore battery, running the house from solar by day and the battery by night. If you add the iStore backup gateway, it isolates from the grid in a blackout and powers selected circuits.
Is iStore made in Australia?
Support and warranty are run from Australia.
Does the iStore 270 have WiFi?
For the iStore solar range, the single-phase hybrid inverter has built-in WLAN connectivity and the EV charger supports both Wi-Fi and Ethernet.
