Involtis is the general importer of Easyway Energy for Austria and brings the UNIV storage systems to the Austrian market directly, without intermediaries. For inverters, we are specialists in Deye – advice and service from a single source. More about our brands

Our Easyway battery storage systems are compatible with most common inverter brands, particularly models with CAN or RS485 communication – with more than 20 inverter models, including the entire Deye LV hybrid series SG05LP3 (6–20 kW). We will gladly confirm which models work together in your specific project; we send the compatibility list on request.

According to the datasheet, our LiFePO4 batteries of the UNIV series support a depth of discharge of up to 90 % DOD.

According to the datasheet, the Easyway UNIV storage systems are designed for more than 8,000 charge cycles (at 25 °C and 80 % depth of discharge). Read more about the technology in our knowledge article LiFePO4 battery storage.

Yes – in combination with a hybrid-capable inverter and a battery storage system, our systems provide an emergency power supply (backup function) in the event of a grid failure.

For a typical single-family home we recommend a storage capacity of 10 to 15 kWh – depending on electricity consumption and the size of the PV system. We will gladly advise you on sizing for your specific project.

The Easyway UNIV-16kWh battery storage systems are tested and certified to IEC 62619:2022; in addition there is CE conformity, UL 1973 (cell), UN38.3 and the manufacturer’s ISO 9001:2015, among others. The Deye inverters carry CE marking (EU declaration of conformity) and meet the grid connection standards listed in the Deye datasheet, including OVE guideline R25. Details can be found on the product pages under “Certifications”, e.g. for the UNIV 16 kWh. We hold all certificates and test reports in the original, and they can be inspected on request.

Our UNIV battery storage systems meet the requirements of OIB Guideline 2 (fire protection, 2023 edition): the passed safety test and proven thermal runaway protection are documented. This allows an installation with up to 100 kWh total capacity in living areas without a separate fire protection room. We recommend always coordinating the specific installation with the locally responsible authorities – we will gladly support you with this.

You will find the datasheets (PDF, in German) directly on the respective product pages in the “Downloads” section – for the Deye inverters also the EU declaration of conformity. We send further documents such as the compatibility list on request.

Deye inverters: according to the manufacturer’s datasheet, 5 years or up to 10 years, depending on the country and conditions of installation – details on request.
Easyway battery storage (UNIV): 10 years according to the manufacturer’s datasheet – the exact warranty conditions are available on request.
Manufacturer warranties are subject to the warranty conditions of the respective manufacturer.

Get in touch with us – ideally via the contact form (subject “Service / warranty”), by phone or via WhatsApp. In a warranty case we analyse the affected device – whether inverter or battery – thoroughly and specifically, with the aim of a rapid fault diagnosis. Our service centre is located at our warehouse in Landscha an der Mur; our regional service team in Styria is quickly on hand if problems arise.

Contact us directly via our contact page, by phone or via WhatsApp – the Involtis team helps quickly and without fuss. We support you with commissioning, firmware questions and system optimisation, and also take care of inverter software updates.

You monitor Deye inverters with Deye Cloud, Deye’s official monitoring platform – in the browser or as an app for iOS and Android. This gives you access to performance data and system status at any time. We will gladly help you with the setup. More about service & Deye Cloud
