Technical FAQs
Do you provide service and support for the Besst AIO?
Yes. Every Besst AIO comes with a dedicated service and maintenance package – covering remote monitoring, firmware updates, and timely technical support.
What warranty do I get, and how long will the battery last?
We offer a full 10-year warranty on the Besst AIO system, including batteries. With proper usage – regular maintenance and optimal charging – the batteries are designed to retain at least 80% capacity after 10 years, ensuring long-term performance.
Do you help with installation and setup?
Absolutely. We coordinate with certified installers, provide a clear installation checklist, and offer post-installation commissioning to ensure your Besst AIO is configured correctly and integrated seamlessly with your system.
Do I need a grid connection?
Yes. A grid connection is essential. Before connecting your Besst AIO, you need to confirm and approve the installation with your local DSO (distribution system operator). A dual-way meter must also be installed by the DSO.
Do I need solar panels (PV) to install the battery?
No. Besst AIO batteries operate independently without PV. However, adding PV panels can significantly improve your household savings and earnings. You can order an optimal PV system directly from our website.
If I have solar panels, is it possible to use them with Besst AIO?
Yes. No matter what inverter you already have, Besst AIO units come with brand-new DEYE hybrid inverters, equipped with integrated MPPT controllers for PV connection. You can keep your existing inverter setup and simply connect Besst AIO to the grid. For details, please download the relevant Besst AIO manual.
Can I track how my system is performing?
Yes. Our online portal and mobile app give you real-time visibility into your savings, earnings, battery status, solar input, and grid flows – with easy-to-read charts and insights.
Can I expand or relocate my system later?
Yes. The Besst AIO is modular and can be expanded with additional units as needed. If you move, the system can be professionally de-installed and reinstalled at a new site – so your investment stays with you.
How long does the installation take?
Do I need special permits for the installation?
Will the battery work during a power outage?
What maintenance is required?
Our battery systems require minimal maintenance. Regular checks by our team, usually annually, ensure your system continues to perform optimally. We remotely follow the battery status via our app.
