Why distributors source balcony storage from SunoraX
Factory-direct, container pricing. Minimum order is one 40HQ container and models can be mixed, so a first balcony-storage order can share the container with portable power stations or home batteries.
OEM / ODM programme. Logo, colour, socket standard, packaging and app branding for private-label channels.
Production control. 15-step in-production inspection and in-house reliability testing (climate, vibration, aging) before shipment.
Documentation for the EU channel. CE, UN38.3, IEC battery safety reports, MSDS and a VDE-AR-N 4105 report are available on request; the one-page datasheet can be downloaded from the product page.
European warehouse. Active partners can replenish from EU stock between container orders.

Plug-in rules differ by country
Plug-in balcony systems are regulated at national level: the permitted feed-in limit, registration steps and meter requirements differ between Germany, the Netherlands, Belgium, Austria, Italy and Spain. Tell us the destination country in your enquiry and we will confirm the configuration (feed-in setting, plug type, meter) that applies. A battery description alone does not confirm that the complete installation is compliant; the installer of record should check local requirements.

What to include in a balcony storage wholesale enquiry
