Owning an electric car in NSW can feel like a win for your wallet and the planet. You skip the petrol station, you drive on clean energy, and you know you are part of the future.
The flip side is the surprise on your electricity bill after a few weeks of home charging. If you have solar panels, you may also know the frustration of exporting excess energy to the grid for cents and then buying it back at peak prices.
At PSC Energy, we’re installing a system that changes that. The SigenStor solar battery and energy management system from Sigenergy stores your excess solar or energy imported from the grid. It feeds it to your EV when you choose. We’re here today to show you how.
In this article, you’ll learn about the following:
- Use More of Your Own Solar Power
- Future-Proof Your Setup
- Energy Security
- Smart Control from Your Phone
Here are the top five reasons homeowners in NSW are pairing SigenStor with their EVs and why you might want to join them.
1. Use More of Your Own Solar Power
The Problem
Midday sunshine pours onto your panels when you are at work. You cannot use it all, so you send it to the grid. Your feed-in tariff might be around 5 to 10 cents per kWh. When you come home and plug in your EV, you repurchase power for 38 cents per kWh. That gap costs you money every single day.
How SigenStor Helps
A SigenStor stores your excess solar for later. When the sun goes down, you use the stored solar energy to charge your EV overnight. You avoid peak rates, and you keep your EV running on your own clean energy.
- Single-phase homes can still store plenty of energy for overnight charging.
- Three-phase homes can charge faster and handle more load.
Quick Takeaway
- Keep more of the energy you generate.
- Charge your EV on your own solar instead of grid power.
- Reduce your reliance on your electricity retailer.

2. Future-Proof Your Setup
The Problem
Energy prices, EV models and government rules are changing fast. What works today might feel outdated in just a few years. Many homeowners worry about locking themselves into a system that cannot keep up with new technology or future needs.
How SigenStor Helps
SigenStor is designed to grow with you. If you buy another EV, you can expand your battery storage by adding more modules instead of replacing the whole system. It supports both AC and DC charging, so you can adapt as EVs evolve. If your EV brand offers bidirectional charging in the future, SigenStor is ready to manage V2H and V2G flows if your car supports these features.
Quick Takeaway
- Add battery capacity as your energy use grows.
- Stay compatible with new EV brands and charging types.
- Keep your system relevant as tariffs and technology change.

3. Energy Security
The Problem
NSW blackouts happen during summer heatwaves and storms. If your EV is low and the grid goes down, you are stuck in one place.
How SigenStor Helps
If you set up your SigenStor for backup power, it can send stored energy to your EV even when the grid is down. You can also run essential household loads.
Bidirectional charging takes this further:
- V2H (Vehicle-to-Home) lets your EV act like a giant battery for your house.
- V2G (Vehicle-to-Grid) enables you to sell power back when the grid needs it most.
These features depend on your EV model and charging gear, but the SigenStor can manage them when compatible.
Quick Takeaway
- Charge your EV during blackouts if the system is set up for backup.
- Use your EV to power your home with V2H.
- Earn extra by selling back to the grid with V2G.

4. Smart Control from Your Phone
The Problem
Old-school energy management meant turning lights off or using timers. It was easy to forget where or what was drawing electricity.
How SigenStor Helps
The SigenStor mySigen App shows:
- How much energy is in your battery.
- Where it is going.
- What it is costing you when you pull energy from the grid.
You can:
- Schedule your EV charging for solar hours, off-peak times, or both.
- Set priorities so your home or EV gets power first.
- Adjust settings from anywhere.
The app is clean and straightforward. If you can browse social media, you can run your SigenStor.
If you’re still unconvinced, here’s another component to the mySigen App: it can run on AI. It uses ChatGPT to learn your energy habits. It can take over charging and discharging your battery and provide all the above insights with simple and straightforward charts and stats.
Quick Takeaway
- Manage your energy from anywhere.
- Match charging to your solar production or off-peak rates.
- Avoid manual work and still save money.
