Solar energy company Sun King has expanded its PowerHub solar inverter range to 30 kilowatts and introduced a solar-powered freezer as part of efforts to provide households and businesses in Nigeria with alternatives to unreliable electricity and the rising cost of generator use.
The company unveiled the new products at a ceremony attended by customers, business partners and government representatives, where stakeholders discussed the growing role of solar energy in meeting the power needs of Nigerian homes and businesses.
The expansion increases Sun King’s inverter offering from its existing 2.2kW and 3.3kW systems to include 5kW, 10kW, 15kW and 30kW models.
According to the company, the expanded range is designed to allow customers to begin with a system that matches their immediate electricity needs and increase their capacity as their energy requirements grow.
Sun King’s Country Business Leader in Nigeria, Lisbon Ogunsammi, said the systems were designed with scalability in mind, allowing customers to add battery storage and solar panels without having to replace the inverter system they initially purchased.
“Our rooftop solar range now runs from a hyper-affordable solar home system all the way to 30kW of inverter power. Customers can start where their budget is, expand as they grow, and stay with one company throughout. That is big energy: power that keeps up with your ambitions, whatever their scale,” he stated.
The company said the expanded PowerHub range is intended to serve a broad customer base, from households requiring basic backup power to larger homes and businesses with significantly higher electricity demands.
Beyond power generation and storage, Sun King also unveiled PowerFreeze, a solar-powered freezer targeted at households and small businesses that depend on refrigeration to preserve food and other perishable goods.
The introduction of the freezer comes against the backdrop of persistent electricity challenges, which have increased the dependence of many businesses and households on petrol and diesel-powered generators.
According to the company, PowerFreeze is designed to reduce the impact of power interruptions on food preservation while offering an alternative to conventional generator-powered refrigeration.
Vice President, Sales – West and Central Africa, Omoyemi Tuga, said the 210-litre unit could function either as a refrigerator or freezer and was built with heavy insulation and five integrated ice batteries.
The batteries, she explained, are designed to retain cold temperatures overnight and during periods of reduced sunlight, including overcast weather.
The PowerFreeze package comprises the freezer, solar panels, a control unit and battery. The energy control unit can also be charged from the national grid when solar energy is insufficient.
In addition to supporting the freezer, the control unit can be used to charge mobile phones and laptops and power energy-efficient lighting, giving households and small businesses access to multiple uses from the same solar system.
Tuga said the product was already demonstrating benefits among food vendors and households using it, particularly those facing losses from food spoilage during prolonged power outages.
“PowerFreeze has shown clear value for the food vendors and households in Nigeria who are already using it, particularly those dealing with food spoilage caused by unreliable power.
“For small businesses, avoiding diesel generators can materially improve margins. For families, it means less food wasted and more predictable household costs,” Tuga added.
The latest product launches reflect the growing demand for distributed energy solutions in Nigeria, where households and businesses frequently combine grid electricity with alternative sources such as solar systems and generators.
By extending its inverter capacity to 30kW and adding refrigeration to its solar-powered product portfolio, Sun King is positioning its offerings to cover a wider range of residential and commercial electricity needs.
