ONESUN: Delivering the Best All-in-One Solar + Inverter Solutions for B2B Clients in Nigeria

As Nigeria continues to face electricity supply challenges, the demand for reliable solar energy and energy-storage solutions is higher than ever. For B2B customers — including commercial facilities, small and medium-sized enterprises (SMEs), factories, telecom base stations, and community microgrids — ONESUN emerges as an ideal partner, offering a full, integrated solar energy solution tailored for the Nigerian market.

Founded in 2014, ONESUN specializes in designing and manufacturing integrated photovoltaic (PV) energy storage systems, combining lithium-ion batteries, hybrid inverters, and other components in a vertically integrated supply chain.

Why ONESUN is a Good Fit for Nigeria

* Localized readiness & regulatory compliance: In 2025, ONESUN’s PV systems passed SONCAP certification — a crucial approval for selling and deploying solar equipment in Nigeria.
* Global experience + proven reliability: The company has exported its integrated solar solutions to more than 70 countries.
* Strong technical foundations: ONESUN’s R&D team includes former automotive-grade battery and BMS engineers (from companies such as BYD), applying automotive-grade battery management safety and longevity standards to stationary energy storage. 

What ONESUN Offers: Integrated All-In-One Systems

ONESUN’s core product portfolio includes “all-in-one” solar energy storage systems that integrate:

* Hybrid inverters (3 kW to 10 kW and above),
* LiFePO₄-based lithium-ion batteries (5.12 kWh to 10 kWh or greater),
* Built-in MPPT charge controllers, and
* Smart BMS (battery management system) for safety and long battery life.

Thanks to this integration, ONESUN’s units are compact, easy to install (floor-standing or wall-mounted), and can operate both off-grid and grid-tied — ideal for Nigeria, where grid stability can be unpredictable. 

Such integrated systems greatly simplify logistics and installation for B2B customers: instead of sourcing separate inverters, batteries, charge controllers, and accessories, businesses receive a plug-and-play solution — reducing complexity, installation time, and integration risk.

ONESUN’s Strategy for Nigeria & West Africa

Recognizing the huge potential in Nigeria and surrounding regions, ONESUN is pursuing a localization strategy. The company aims to establish joint manufacturing and service facilities in Nigeria in cooperation with local partners. 

This localized presence would bring multiple benefits to B2B clients: faster supply chains, lower costs, local after-sales service and maintenance, easier access to spare parts — all improving the long-term viability and reliability of solar installations in Nigeria.

Moreover, ONESUN offers flexible business models such as “PayGo” (pay-as-you-go) financing, enabling businesses and communities to adopt solar systems without prohibitive upfront investment.

Why B2B Clients in Nigeria Should Consider ONESUN

For enterprises, industrial users, telecom operators, and community energy projects in Nigeria, ONESUN offers a compelling value proposition:

* A complete turnkey solution — inverter + battery + controls — simplifying procurement and deployment.
* Solutions certified for Nigeria, complying with local regulations (e.g. SONCAP).
* Robust, automotive-grade battery and BMS technology to ensure safety and long lifespan even in challenging environments.
* Flexibility: off-grid or grid-tied, scalable capacity, floor or wall installation, suitable for offices, factories, telecom sites, or remote communities.
* Local-market strategy and support, including potential local manufacturing and financing models — promising better cost efficiency, reliability, and maintenance support.

Conclusion: A Strategic Solar-Energy Partner for Nigeria’s B2B Sector

As Nigeria seeks sustainable, stable, and affordable power solutions, ONESUN stands out as a trusted international brand offering end-to-end, integrated solar + storage systems optimized for local conditions. By combining advanced inverter and battery technology, regulatory compliance, and a clear commitment to localization, ONESUN provides what many Nigerian businesses and project developers are looking for: a reliable, plug-and-play solar energy solution — scalable, cost-effective, and future-proof.

For B2B clients in Nigeria — from SME offices to telecom towers to community electrification projects — partnering with ONESUN offers a strong path toward energy independence, reduced operating costs, and sustainable power infrastructure.
