About ONSA Plus

Not just boxes. A partnership.

ONSA Plus is a European B2B wholesale distributor of solar PV, battery storage, heat pumps and EV chargers, supplying professional installers in all 27 EU countries, whether you fit one system a month or run a busy crew. We hold 1,500+ products from 25+ brands including Huawei, Solis, SolaX and Dyness in our three EU warehouses. In-stock items are dispatched within 24 hours, to your premises or straight to the installation site.

We are not only a trading house. We design and install energy systems ourselves, so questions about sizing and compatibility are answered by a dedicated specialist who knows the setup from practice, not a ticket in a queue. And there is no minimum order, so you buy what the job needs. We sell what we install ourselves. Frequently asked questions
