Why SustainStorage?

SustainStorage offers turn-key, fully integrated and modular, containerised battery energy storage systems (BESS) with optional PV integration. Designed together with our technology partners, our product range is applicable to both off-grid and grid-tied energy storage applications such as back-up, peak shaving, energy shifting and frequency regulation. Where required, the SUSTAINSTORAGETM BESS range can be pre-commissioned with an energy management system (EMS), black start capability and diesel generator integration.

Turn-key solution

Containerised BESS

SUSTAINSTORAGETM BESS containers are turn-key solutions designed for commercial and industrial (C&I) clients, providing much needed power back-up during loadshedding

Container-Diagram

Hybrid or PCS inverter choice for required storage application (back-up, peak shaving, etc.) which can be paralleled for increased capacity

24/7 real time remote monitoring of key equipment (convenient for parameter setting and maintenance), and accessible for ease of operation

Custom-built container, with insulated walls and configured with unistruts to secure wall-mounted equipment

In-house engineering and selection of BESS technology package (i.e., integration of various inverter and battery brands & battery chemistry) 

Battery modules can be connected in series to reach required inverter voltage range 

Flexible HV battery racks which can be connected in parallel for large scale BESS requirements

Partitioned air-conditioned and dust proof battery room with fire suppression system (FSS)

Customised ISO shipping containers to client specifications (e.g., windows and doors for site offices, burglar proofing or alarms, etc.)
