Two expensive windows a day
In the high-demand season (June to August) the weekday peaks run 06:00–08:00 and 17:00–20:00; for the rest of the year 07:00–09:00 and 18:00–21:00 (Eskom Megaflex and Miniflex, 2026/27).

Battery storage for manufacturing.
For a factory, electricity is both a cost line and a production risk. Storage lowers the first and removes much of the second, and pairs naturally with the solar array on the roof.
01 · The problem
What the site
is up against.
Demand
NMD set by one bad half-hour
A shift change or a start-up after an outage can set the monthly demand charge on its own.
Quality
Power factor and interruptions
Poor power factor attracts reactive-energy charges, and a short interruption can scrap a batch.
02 · What storage does
What the battery
does about it.
- 01Peak shiftingMoves energy bought in the peak windows to off-peak or to stored solar.
- 02Demand ceilingHolds the half-hour demand under a set limit, every month.
- 03Power factor correctionFour-quadrant conversion supplies reactive power locally, even when the battery is idle.
- 04Solar self-consumptionStores midday surplus instead of exporting it below the price you buy at.
- 05Ride-throughWith a static transfer switch, the plant islands in under 10 ms and keeps critical lines running.
03 · Typical configuration
Indicative,
before the load study.
| Systems | A200 to A400, or A100 blocks in 1 MWh steps |
| Connection | 400 V for integrated units, or MV through a skid |
| Duration | 2 hours for peak shifting; 4 hours where the evening peak is long |
| Pairs with | Rooftop or ground-mount PV, existing gensets |
| Commercial model | Purchase with bank finance, PPA, or hybrid with an owned solar array |
Every configuration is sized from the site's own interval data and tariff; this is a starting point, not a quote.
04 · Questions
Asked by manufacturing
buyers.
What size of battery does a typical factory need?
It depends on how much energy the site uses in the peak windows and how high the demand ceiling is. The free load study sizes it from twelve months of interval data; the Savings Studio gives a first answer from your bill.
Can the battery correct our power factor?
Yes. The conversion is four-quadrant, so it supplies reactive power locally across its capability curve, with power factor adjustable from −1 to +1.
Will it work with our existing solar?
Yes. Solaris dispatches solar, storage, grid and generator together, so surplus that would be exported or curtailed charges the battery instead.
