SustainSolar hospital
The hospital extension is equipped with a solar modular configuration with battery storage by SustainSolar, using the Siemens Sicam microgrid controller to provide the hospital with clean energy 24/7.

Mid-February this year, SustainSolar expanded its footprint electrifying health services by adding yet another hospital project to its portfolio, this time in its home country of South Africa – a first for the company.

SustainSolar delivered a solar PV and battery backup solution to a joint initiative to build a modular treatment facility at the Cecilia Makiwane Hospital in East London.

Sponsored by Siemens South Africa together with the Solidarity Fund, Siemens Healthineers, Siemens Caring Hands, the GIZ and Aspen Pharmacare, this project aims to ease the burden on strained hospital space as the third wave of COVID-19 infections looms.

The Sustain Storage system from SustainSolar.

With a 100-bed capacity, the separate facility provides the main hospital with a desperately-needed addition of ten new intensive care beds, 90 ward beds, diagnostics services, and a pharmacy store. The extension ensures access to modern, efficient and superior-high-quality equipment.

SustainSolar’s premium quality containerised 20-foot system is equipped with 60kWp of photovoltaic (PV) capacity, 222kWh of Lithium-Ion battery and incorporates the Siemens Microgrid Controller, a power management system for utilities and microgrids. This project is the first deployment of SustainSolar’s newest product range addition, the SustainStorage.  

A fully integrated, AC-connected containerised battery energy storage system (BESS) – with optional PV integration – the Sustain Storage product has been designed for demanding energy storage applications such as emergency backup, load shifting and peak shaving. 

Using Solar MD batteries and SMA inverters, this new product comes in different sizes from 222kWh to 414kWh and is ideally suited for projects with large power requirements or wherever integration of an existing PV or diesel generator is needed. SustainSolar is currently developing larger configurations which will be launched in the next few months.
