Choose Heiwit's new 10 kWh sodium ion batteries for your photovoltaic system: efficiency, sustainability and zero worries

Introduction

Do you already have a photovoltaic system and are looking for a way to make the most of all the energy you produce? Heiwit's new 10 kWh sodium-ion batteries are the ideal solution for maximising self-consumption and further reducing energy costs. Thanks to their state-of-the-art technology, these batteries offer safety, sustainability and high performance without the limitations of conventional lithium systems. Discover all the benefits of adding a storage system to your system and how Heiwit can simplify the installation process.

1. Why choose a storage system for your photovoltaic system?

• Maximise self-consumption and reduce your bill: A storage system allows you to store the energy produced by your photovoltaic system during sunny hours and use it when you need it most, such as in the evenings or during consumption peaks. By doing so, you minimise the need to purchase energy from the grid and optimise your energy independence.
• Protection against blackouts: In the event of a grid outage, if the system has a Heiwit inverter with a backup output, the batteries keep powering the loads connected to that line, within the output's power rating (up to 5 kW) and as long as the battery has charge available.
• Contribution to environmental sustainabilityA storage system allows you to make the most of the renewable energy you produce, reducing your carbon footprint and contributing to the fight against climate change.

2. Heiwit sodium-ion batteries: lithium-free and with reduced thermal risk

• Lithium-free, no compromise: Heiwit's sodium ion batteries do not contain lithium, a material that is increasingly difficult to source and presents environmental problems related to its extraction. With our batteries, you opt for a solution that does not depend on lithium.
• No memory effectUnlike older storage technologies, Heiwit sodium ion batteries do not suffer from the memory effect. This means that they can be recharged and discharged freely, maintaining their capacity over time.
• Recyclability: Heiwit batteries are designed to facilitate the recovery and recycling of materials at the end of their life cycle.
• Long life: Thanks to their robust construction and advanced technology, Heiwit batteries are designed for a long service life: over 6,500 estimated cycles at 90% DoD with 70% residual capacity (NA-48V210Ah), allowing you to enjoy the benefits of energy storage for a long time.

3. Compatibility with your photovoltaic system: what you need to know

• Compatibility Requirements: In order to install our 10 kWh sodium ion batteries, it is important that your photovoltaic system is not incentivised by the First Energy Account. This limitation is necessary in order to comply with the incentive rules in force. However, there is no problem for installations benefiting from the Second, Third, Fourth or Fifth Conto Energia, as well as for those not incentivised.
• Simple and transparent installation: Connecting Heiwit batteries to your existing system is a process that requires the involvement of a specialist installer. Heiwit batteries only work with a Heiwit inverter, not with inverters from other brands. The Heiwit hybrid inverter is connected on the AC line, alongside the existing inverter, which stays where it is.
• Bureaucratic compliance: To install Heiwit batteries, you need to notify the GSE (Gestore dei Servizi Energetici) and E-Distribuzione, the entity that manages the electricity distribution network. Your trusted installer will be able to support you in this paperwork, or, if you prefer, the Heiwit team is available to assist you.

4. The economic advantages of a Heiwit storage system

• Immediate and long-term savings: By adding Heiwit batteries to your photovoltaic system, you can reduce your dependence on the electricity grid even further and save even more on energy costs. The 10 kWh capacity allows you to cover a significant part of your daily consumption, especially during times when the system is not producing.
• An investment for the future: Although the initial investment for installing batteries may seem significant, the long-term benefits are considerable. The long service life of our batteries helps pay back the investment over time, on a timescale that depends on consumption and energy prices, turning your photovoltaic system into your own personal power station.
• Take advantage of our discount coupon: To celebrate the launch of the new batteries, Heiwit is offering a discount coupon worth €2,000 on the installation of the 10 kWh batteries. Contact us now to find out how you can get the discount and add an efficient and sustainable storage system to your installation.

5. How does the Heiwit battery installation process work?

• Step 1: Evaluation of the installation: Contact your trusted installer to check that our batteries are compatible with your photovoltaic system. If you do not have a regular installer, Heiwit can put you in touch with an installer from the Heiwit network.
• Step 2: Choosing the Heiwit inverter: A Heiwit inverter is required, because the batteries do not work with inverters from other brands. The Heiwit inverter is connected on the AC line and sits alongside the existing one, which stays in place.
• Step 3: Communication to the GSE and E-Distribuzione: The installer will notify the GSE and E-Distribuzione of the intervention, ensuring that everything complies with the regulations.
• Step 4: Install batteriesOnce the paperwork is completed, Heiwit batteries will be installed and connected to your system, ready to improve the energy efficiency of your home or business.
