Sigenergy
An integrated solar and storage platform: hybrid inverters, stackable SigenStack batteries and a gateway that run as one system.
Established in 2018, with a team bringing over a decade of energy experience. We deliver Power, Water & Connectivity services to businesses, landlords and estates, from our head office in Randburg, Johannesburg.
Northlands Energy is a national independent power producer and EPC, and a specialist utility company, headquartered in Randburg, Johannesburg. We generate energy with state-of-the-art solar and battery storage, managed by the Northlands Energy EMS, powered by world-leading AI. We meter and bill it on billing-grade meters, with both STS prepaid and virtual prepaid. As water specialists, we install water backup with precision metering, and run billing-grade sub-metering for multi-tenant property. And through Utility Connect, our connectivity business, we connect buildings with an ISP powered by renewable energy.
Northlands Energy is a national independent power producer and EPC specialist. We design, build and manage solar, battery storage and smart metering for commercial, industrial and property developments, from engineering and procurement through construction to ongoing support. Systems run from rooftop solar to containerised battery plant, tailored to the property. You can purchase outright, take a structured lease or choose a long-term power purchase agreement.
“With deep local knowledge and proven technical expertise, we don’t just install systems: we build energy ecosystems tailored for South African conditions.”
We are not installers who disappear after commissioning. As an independent power producer we fund, own and maintain many of the plants we build, so our commercial interests stay aligned with yours for the life of the system.
On a PPA we stay for the full term: we operate the plant, maintain it and bill for the power it makes.
Free site assessment: your load profile, roof, tariffs and goals.
Engineering for your site: solar, high-voltage batteries, generators and smart metering as needed.
Installed, commissioned and supported by Northlands, with a 12-month workmanship guarantee.
Support after commissioning, with optional maintenance, metering and service-level agreements.

An integrated solar and storage platform: hybrid inverters, stackable SigenStack batteries and a gateway that run as one system.

Commercial hybrid and battery inverters that move power between solar, batteries, the grid and generators.

Power optimisers on the panels, so faults show up at panel level, not just at the inverter.

Lithium battery storage, from light-commercial racks to containerised systems.
