Keep the till and the fridge on.
When load-shedding hits, a small shop loses more than the lights: refrigeration stock warms, the point-of-sale terminal drops and the day's takings stop. Real South African inquiries — a "5kva home backup system that is removeable/mobile" and a "Hybrid Solar system to rent" — show the demand for affordable, relocatable backup that also cuts the peak-time bill through arbitrage.
Four costs of a dark shop.
Outages, spoilage, peak tariffs and the need to relocate are the four pressures a small business battery has to answer.
| Pain point | What the data says |
|---|---|
| Load-shedding | Real South African inquiries include a "5kva home backup system that is removeable/mobile" and a "Hybrid Solar system to rent" (EMS-ESS inquiry allocation sheet). |
| Cold-chain risk | Fridges, tills and lighting must run continuously through outages; EMS-ESS switches in 10 ms (UPS, VDE) so refrigeration and point-of-sale never drop. |
| Peak tariffs | Peak shaving with battery storage targets demand charges, and time-of-use arbitrage shifts load off peak-price hours (Redaptive; Dynapower). |
| Relocatable demand | Buyers ask for units they can move or lease; the system rides universal wheels rated 150 kg and installs in about 5 minutes (EMS-ESS product line). |
One unit covers outage and peak.
A 5 kW single-phase system or a 51.2 V 100 Ah rack-cabinet battery holds the store's critical loads — refrigeration, checkout, security and lighting — and switches to battery in 10 ms when the grid fails, so the freezer never notices. Between outages, the same unit arbitrages the tariff: it charges on cheap or solar power and discharges during the peak-price window, trimming the demand charge that peaks when compressors and tills run together.
- 10 ms switchover keeps tills and fridges running through load-shedding
- Universal wheels rated 150 kg make the unit easy to relocate or lease out
- 5.12 kWh modules stack to 40.96 kWh as the shop grows
- Peak-valley arbitrage and demand-charge peak shaving scheduling
How shop requirements map to EMS-ESS.
Every shop-floor constraint maps to a certified, install-ready product parameter.
