Start From Your Site, Not From a Datasheet

Four Product Lines, One Specification

Built to Our Specification, Released Against Our Test Protocol

We write the bill of materials, the process specification and the acceptance criteria. Production runs at qualified partner factories, and no unit leaves without a factory acceptance test against that protocol. The test report travels with the goods, serial number by serial number.

• Certification you can verify. Every SKU ships with CE, IEC 62619, UN38.3 and MSDS documentation. Certificate numbers are provided for independent verification.
• One specification, four lines. Residential, C&I, container and telecom are built to the same process specification and pass the same QA gates. The factory changes with the product; the specification does not.
• OEM from 1 × 20 ft container. Your logo, your manual, your packaging. MOQ starts at one container for residential lines.
• Engineering, not just quoting. We size the array, the battery and the generator for your load profile before we send a price.

Certified, Documented, and Clear About the Details

Every unit ships CE marked (LVD, EMC, RoHS) with IEC 62619, UN38.3 and MSDS documentation, so it can be sold and installed legally across the EU and UK.

Where a project needs a national grid-code certificate — EN 50549, VDE-AR-N 4105, G99, CEI 0-21 — we confirm the certificate package for your country before we quote, and we tell you in writing which route gets your site commissioned fastest.

Most of our volume goes into off-grid, backup, weak-grid, telecom and behind-the-meter sites, where CE plus IEC 62619 is exactly what the authority having jurisdiction asks for.

Technical Notes

How we size systems, what the standards actually require, and where the numbers come from. Written from site experience, not from datasheets.

• What Size Battery Cabinet Does a Factory Actually Need? — three numbers decide it, and none of them is annual kWh.
• Diesel vs Solar-Hybrid at an Off-Grid Telecom Site — fuel is only 40% of what a diesel site costs over ten years.
• Lead-Acid to Lithium: What Actually Changes on Site — the charger, not the battery, decides whether the retrofit works.
• The Five Documents That Decide Whether a Battery Container Clears Customs — missing one stops the shipment, not slows it.
