Stage Zero inverters added to Cape Town’s approved PV list

Stage Zero’s Gilbert 48V hybrid PV inverter series has been added to the City of Cape Town’s Approved Photovoltaic (PV) Inverter List, a step that signals compliance with recognised grid‑connection standards. The listing covers the 3kVA, 5kVA, 6kVA and 8kVA grid‑tied models.

The City’s list is widely used in South Africa’s small‑scale embedded generation (SSEG) processes as a baseline for inverter compliance.

It identifies equipment tested against requirements such as NRS 097‑2‑1, ensuring safe connection to municipal electricity networks.

Investment

Stage Zero said the approval reflects its investment in building systems that meet technical and regulatory expectations.

“Solar decisions are no longer only about panels, batteries, and backup. Customers also need confidence that the system installed at their home or business is safe, compliant, and supported over time,” said Peter Westerman, Chief Operations Officer.

“The addition of the Gilbert Series reflects the investment we have made in product development, testing, regulatory readiness, and long‑term customer confidence.”

Gilbert series

The Gilbert Series is part of Stage Zero’s locally developed technology, supported by in‑house research and development.

The company says this allows it to adapt systems to South African conditions, including rising electricity costs, grid instability, affordability, and the need for reliable after‑sales support.

Westerman noted that approval is not automatic.

“Getting equipment onto the City’s approved list requires time, resources, and a clear commitment to meeting the standards expected of safe, grid‑tied PV installations.

“This is part of building solutions that are not only financially accessible, but appropriate for the realities South African customers face every day.”

Electricity

Stage Zero operates a subscription‑based model aimed at lowering upfront costs. For Cape Town customers, the inclusion of the Gilbert Series means installations can proceed with recognised equipment under the City’s compliance framework.

“As electricity becomes more expensive and harder to plan around, customers need more than a system that works on day one. They need a solution that is compliant, monitored, supported, and built around long-term performance,” said Westerman.
