30kW engineered for Warehouses in Durban
High Eskom tariffs and power instability directly affect warehouses operations across Durban, eThekwini. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Durban sit on the N3 Durban to Gauteng corridor, where vast unused roof area and rising fixed demand charges make generation on site the lowest-risk hedge available.
Synchronising existing gensets with PV and storage so diesel becomes a last resort instead of a monthly cost centre. Warehouses carry a load profile dominated by daytime lighting, forklift charging and dock equipment, which is exactly where solar generation overlaps hardest with your billing peaks.
Pair your cooling, refrigeration and commercial aircon systems directly with solar PV generation to cut high peak-demand electrical charges. Thermal pre-cooling during peak irradiance hours shifts chiller demand off the eThekwini Metro account entirely.

Questions from Durban operators
How long does a 30kW installation in Durban take?
A 30kW plant on a warehouse in Durban typically takes 4 to 10 weeks from signed order, including structural assessment, eThekwini Metro SSEG paperwork and commissioning.
Do we need approval from eThekwini Metro?
Yes. Any grid-connected embedded generation in Durban, eThekwini must be registered as SSEG. Reyds handles the full application, professional engineer sign-off and NRS 097-2-1 compliance documentation.
Can the system run our aircon and refrigeration during load shedding?
With hybrid inverters and LFP storage, cooling, refrigeration and commercial aircon can be carried through outages while also clipping peak-demand charges on your warehouse account.
