How to choose the right solar battery for your self-consumption system?
In a context of accelerated energy transition, more and more households are opting to install solar panels to generate their own energy. But true energy independence is not achieved through generation alone: storage is the key. Choosing the right solar battery can make the difference between an efficient system and a limited one. At IONLY, as a European manufacturer specializing in lithium-ion batteries for solar storage, we want to help you make an informed decision.
What to consider when buying a solar home battery
Before choosing a battery for your self-consumption installation, it is important to be clear about several key criteria:
Chemical technology
Lithium-ion batteries – especially those based on LiFePO₄ (lithium iron phosphate) technology – offer greater safety, longer service life and a better useful discharge rate than other technologies such as lead-acid. At IONLY we rely exclusively on LiFePO₄ for its advantages in efficiency, thermal safety and sustainability.
2. Usable capacity and scalability
It is important that the battery is sized according to your consumption and generation habits. But just as important is that it can be easily scaled if your needs change. Our solutions are modular, so you can start with a minimum capacity and expand in the future without changing the entire system.
3. Compatibility and integration
A good battery must be compatible with your inverter and your energy management system (EMS). IONLY solutions are open and easily integrated, compatible with the main inverters on the market.
4. Real life cycles
Don’t just go by the theoretical figures. Ask how many real cycles the battery offers and under what conditions. Our batteries are designed for more than 6,000 real cycles at 80% DoD, with a slow and stable degradation curve.
5. After-sales service and warranty
Who will give you support if there is a problem? Where are the batteries manufactured? Does the company have traceability of each module? In IONLY we give real warranty from Europe, with direct technical support from the manufacturer.
Advantages of batteries “Made in Europe” versus “Made in China”.
The market is saturated with inexpensive imported batteries, but there are key differences you should be aware of:
- Manufacturing quality and control: European batteries, such as IONLY’s, are assembled under the highest quality standards, with full traceability of each cell and each BMS.
- Local technical support: If you buy from a distributor that imports Asian products, the support will depend on the intermediary. We provide direct support from the manufacturer, without intermediaries.
- Regulatory compliance: Europe is raising the regulatory bar with regulations such as EU 2023/1542, which requires sustainability, traceability, reparability and a digital battery passport. At IONLY, we are ahead of the regulation with products 100% designed for the European framework.
- Carbon footprint and sustainability: A battery manufactured and distributed locally has less environmental impact than one transported from Asia. In addition, IONLY is committed to eco-design and repairability to extend the life cycle of each system.
Why IONLY?
At IONLY we don’t sell batteries, we manufacture smart storage solutions designed to last. We focus exclusively on lithium-ion batteries for solar storage because we believe in energy independence as a driver of change.
- We design modular, scalable and repairable batteries.
- We assemble in Europe under technical and ethical standards.
- We are committed to transparency: every technical specification is justified, every component is traced.
- We accompany installers and professionals with clear documentation, agile support and training.
- We do not compete with our customers: we do not sell to the end user. We are a brand 100% oriented to the professional channel.
