750kW engineered for Warehouses in Ermelo
High Eskom tariffs and power instability directly affect warehouses operations across Ermelo, Gert Sibande. Reyds provides engineered, three-phase commercial solar PV and battery storage systems tailored for daytime load shifting and peak demand clipping. Sites in Ermelo sit on the N2 and N17 corridor, where vast unused roof area and rising fixed demand charges make generation on site the lowest-risk hedge available.
Steel-frame ground arrays for sites with spare yard or land, optimised tilt for maximum winter yield. 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 Msukaligwa Municipality account entirely.

Questions from Ermelo operators
How long does a 750kW installation in Ermelo take?
A 750kW plant on a warehouse in Ermelo typically takes 4 to 10 weeks from signed order, including structural assessment, Msukaligwa Municipality SSEG paperwork and commissioning.
Do we need approval from Msukaligwa Municipality?
Yes. Any grid-connected embedded generation in Ermelo, Gert Sibande 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.
