Soltaro AIO2: Smarter Solar & EV Charging

For many homeowners with solar panels and an EV charger, there’s a frustrating gap between when energy is produced and when it’s actually needed.

Solar generation peaks during the day, right when most people are out of the house. Meanwhile energy demand ramps up in the evening, especially with electric vehicle (EV) charging. This mismatch often leads to wasted solar potential and higher energy bills than expected. That’s where the Soltaro AIO2 battery steps in, offering a smarter, more flexible solution designed around real-life usage.

Make it Count – Excess Solar, your EV and the AIO2

One of the standout benefits of the Soltaro AIO2 is its ability to support dual charging. In simple terms, this means you can charge your battery both from excess solar during the day and from the grid overnight using a low-cost tariff. While that might sound obvious, many competing batteries don’t allow this. Some systems restrict grid charging altogether or impose limitations that can even affect warranty coverage if you try to use both charging methods. That leaves homeowners stuck choosing between capturing solar energy or taking advantage of cheaper overnight electricity—when really, you should be able to do both.

Frustrated about missing out on free solar with your EV?

The Soltaro AIO2 is specifically designed to remove that compromise. It actively encourages dual charging because that’s exactly how modern households use energy. During the day, your solar panels can fill the battery with clean, renewable energy that would otherwise be exported back to the grid for minimal return. Then overnight, when electricity rates drop, you can top up the battery again at a lower cost. There are no warranty concerns, no hidden restrictions. Just full flexibility.

This becomes even more valuable when you introduce an EV into the picture. Around 10–30% of solar panel owners now have an electric vehicle, and that number is only growing. EVs typically require significant charging overnight, as that’s when they’re parked at home. However, without a battery that supports dual charging, you may end up relying heavily on grid electricity at standard rates, missing out on the benefits of your own solar system.

With the Soltaro AIO2, your setup works in harmony.

Your solar panels generate energy during the day and store it in the battery instead of sending it away. Then, overnight, you can charge your EV using a mix of stored solar energy and low-cost grid electricity. It’s a much more efficient way to power your home and your vehicle. This maximises savings while reducing reliance on expensive peak-time energy.

Another key advantage is peace of mind. Because the system is designed for this kind of flexible use. Moreover, you don’t have to second-guess how or when you charge your battery. Many other systems come with fine print that can leave users hesitant, worried about voiding warranties or damaging their investment. Soltaro removes that uncertainty by building a product that matches how people actually live.

Ultimately, the goal of installing solar panels is to make the most of the energy you generate. Without the right battery, a large portion of that “free” daytime energy can go unused, especially if you’re not home to benefit from it. The Soltaro AIO2 changes that by capturing and redistributing energy when you need it most, while also taking advantage of cheaper overnight rates.

If you want your solar system to truly work for you. Powering your home, supporting your EV, and delivering real savings, the ability to charge your battery twice isn’t just a bonus. It’s essential. And that’s exactly what the Soltaro AIO2 was built to do.
