Battery storage, sized for every scale.
Small BESS buffers
5 to 15 kWh units for homes, clinics, offices and hotels — locally assembled, installed and serviced.
Containerized BESS
500–1000 kVA stations coupled to modular 2,088 kWh containers — stack them in parallel as demand grows.
Solar energy systems
Photovoltaic supply, installation and maintenance — standalone or paired with a Helios BESS.
Not a machine sale. An energy partnership.
We combine Swiss engineering rigor with a deep understanding of African operating conditions — and unlike one-shot importers, our founder is committed to a lasting presence on the continent, with local service, training and accountability.
We act as sole contractor from A to Z: engineering study, direct factory sourcing from Tier‑1 partners, international logistics, installation, and local after-sales support.
Three pillars, one platform
Small BESS Systems
Assembly, sale, installation and after-sales support of 5–15 kWh units for homes, SMEs, clinics and hotels.
Engineering & Large-Scale BESS
Consulting, sourcing, importation, installation and SAV for projects up to 1,000 kVA and multi-MW storage.
Solar Energy Solutions
Supply, installation and maintenance of photovoltaic systems, standalone or combined with BESS.
Our name carries our roadmap. Helios Hydrogen began with a portable hydrogen generator prototype, the H2‑I400. Today we focus on the storage and solar systems Africa needs now — with hydrogen production as part of our long-term technology roadmap.
Building West Africa's first local BESS assembly line.
A locally assembled, serviceable alternative to fragile imports — and a platform for Tier‑1 manufacturers to enter West Africa without local risk.
From the field
Helios Hydrogen SARL is officially registered in Abidjan
Our legal entity, capital and RCCM registration are in place — the foundation for our BESS and solar engineering practice in Côte d'Ivoire.
Our first prototype: the H2‑I400 hydrogen generator
The build that gave us our name and our engineering credibility — now part of our long-term technology roadmap.
