var DataFaq = {"FaqItems":[{"SubCategory":29,"Question":"","Answer":""},{"SubCategory":47,"Question":"","Answer":""},{"SubCategory":34,"Question":"","Answer":""},{"SubCategory":39,"Question":"Are additional components required to install a VARTA storage system?","Answer":"

Our AC systems are complete systems that do not require additional components. Make sure that components such as circuit breakers, residual current devices, or connecting cables are available on site to connect the device. Our VARTA.wall DC system requires a compatible photovoltaic inverter and all on-site components to which it is connected. The list of compatible inverter manufacturers<\/a> can be found in our downloads in the B2B area.<\/p>"},{"SubCategory":34,"Question":"Are system errors displayed in the online portal?","Answer":"

System errors are displayed as a status message in the portal and the app, provided the storage system is online.<\/p>"},{"SubCategory":45,"Question":"Are the generation system\u2019s data displayed in the online portal?","Answer":"

To display the generation system\u2019s data in the online portal, a PV sensor or a SunSpec connection is required. All compatible manufacturers can be found in the compatibility list for the respective storage system.<\/p>"},{"SubCategory":51,"Question":"Are VARTA batteries environmentally friendly?","Answer":"

In addition to collecting and recycling old batteries, VARTA continuously works to improve product development and manufacturing processes. This includes sustainable waste management, efficient production, reduction of greenhouse gases, high energy efficiency of products, short delivery routes, and a low carbon footprint of our company buildings.<\/p>"},{"SubCategory":28,"Question":"Are VARTA energy storage systems smart systems?","Answer":"

Yes, integrating EMS (Energy Management System) and BMS (Battery Management System) makes VARTA energy storage systems smart. The charging strategy and safety are controlled by the storage system. It can also be connected to a wide range of smart home applications to further optimize self-consumption and self-sufficiency. The VARTA.wall can be used for self-consumption optimization and other smart home applications within the compatibility and functionality scope of the respective inverter. You can check compatibility in the corresponding download area<\/a>.<\/p>"},{"SubCategory":42,"Question":"Can anyone install or make changes to a VARTA energy storage system?","Answer":"

To ensure the safety of our systems, installation, commissioning, maintenance, and any other work on the VARTA energy storage system may only be carried out by registered VARTA specialist partners. To become a specialist partner, training as an electrical specialist in accordance with DGUV Regulation A3 is required.<\/p>"},{"SubCategory":41,"Question":"Can I connect other generators to my VARTA storage system?","Answer":"

Connecting energy sources other than photovoltaic systems is conditionally possible, depending on the technical circumstances and the applicable VARTA warranty conditions.<\/p>"},{"SubCategory":25,"Question":"Can I continue installing VARTA storage systems if my certified employee has left the company?","Answer":"

Yes, the general certification requirement for VARTA energy storage systems has now been removed. After registering as a VARTA installation partner, you can install VARTA energy storage systems directly.<\/p>"},{"SubCategory":59,"Question":"Can I control other electrical devices via the VARTA storage system?","Answer":"

With VARTA.iq, you have full control over your integrated devices. Define the power source, timing, duration, and amount of energy used to charge integrated devices such as heat pumps and wallboxes. The VARTA.iq.link is compatible with more than 700 devices in the Pro package and more than 300 devices in the Basic package.

You can monitor the values of your VARTA battery storage system via our web interface, our online portal, or the mobile app.<\/p>"},{"SubCategory":28,"Question":"Can I use the VARTA storage system in stand-alone mode?","Answer":"

VARTA AC energy storage systems are not designed for island operation. The VARTA element S5 and VARTA one models offer a limited backup power function. The VARTA.wall can provide both island and backup power capability, depending on the hybrid inverter used.<\/p>"},{"SubCategory":30,"Question":"Can two or more VARTA energy storage systems be connected together?","Answer":"

The VARTA pulse neo can be cascaded with up to five additional AC storage systems (VARTA pulse, VARTA element) and used as a cascade master. Cascading the VARTA.wall or linking AC and DC storage systems is currently not possible.<\/p>"},{"SubCategory":55,"Question":"Can VARTA energy storage systems benefit from KfW subsidies?","Answer":"

Yes, VARTA energy storage systems are eligible for KfW subsidies. The required blocking function can be implemented using a data logger or a SunSpec connection.<\/p>"},{"SubCategory":41,"Question":"Do I still need the inverter for my photovoltaic system?","Answer":"

Our AC backup systems VARTA pulse neo and VARTA element require a photovoltaic inverter. This makes installation much easier and more flexible, as no changes need to be made to the existing system. An external inverter is essential for the VARTA.wall DC storage system, as it is a DC storage system. You can use a hybrid inverter (connecting PV system and battery storage to a single inverter) or a separate battery inverter. Only if you want to replace an existing PV inverter with a hybrid inverter as part of the installation will you no longer need the existing PV inverter.<\/p>"},{"SubCategory":28,"Question":"Do VARTA energy storage systems have true three-phase capability?","Answer":"

The VARTA element and VARTA one storage models are true three\u2011phase systems. VARTA one and element backup also support three\u2011phase operation in backup mode. Only the VARTA pulse operates single\u2011phase. The VARTA.wall supports both single\u2011phase and three\u2011phase hybrid inverters. Compatible models are listed in the compatibility<\/a> overview.<\/p>"},{"SubCategory":28,"Question":"Does the Battery Management System (BMS) independently control charging and discharging?","Answer":"

No, charging and discharging of the energy storage system are controlled by the specially developed VARTA Energy Management System (EMS VS-Pro). The BMS handles safety monitoring of the battery cells and manages balancing when cells are connected in series.<\/p>"},{"SubCategory":41,"Question":"Does the generation system have to be three-phase?","Answer":"

No, the generation system can also be unbalanced (e.g., single-phase), as the current sensor balances the generation and consumption power.<\/p>"},{"SubCategory":28,"Question":"For which operating modes are the VARTA energy storage systems designed?","Answer":"

VARTA AG energy storage systems are designed for multiple operating modes to optimize both self\u2011consumption and supply security:<\/p>\r\n
