If you have lived in South Africa for more than a year, you already know the routine: the TV goes black, the router lights die and the match carries on without you. Load shedding IPTV planning is simply about making sure the three or four small devices that carry your stream stay powered when the grid does not. In this guide, the IPTV South Africa Tech Desk shares the power budgets we measured with a plug-in energy meter, the runtime maths we use to size batteries, and the setups we trust in our own homes in Randburg, Centurion and Durbanville.
Load shedding in 2026: the honest picture
Let us be accurate. Eskom's scheduled load shedding was largely suspended through much of 2024 and 2025, and many households have gone months without checking EskomSePush. That is real progress. But the power still goes off, and for reasons that have nothing to do with national stages:
- Load reduction — targeted cuts in some areas where the network is overloaded, often in the evening peak.
- Municipal faults — tripped substations and failed transformers, especially after heatwaves in Gauteng or heavy rain in KZN.
- Cable theft and vandalism — an outage that can last a day or more while cables are replaced.
- Storms — Highveld lightning season regularly takes out supply.
So the question is not whether Stage 6 will return (nobody can promise either way) but whether your IPTV South Africa subscription survives the next two-hour blackout. A small investment of a few hundred Rand covers the internet side; a bigger one covers the TV too.
Does fibre work during a power outage?
Fibre is passive glass between your house and the street, but the active equipment in between needs power. Fibre network operators such as Openserve, Vumatel, MetroFibre, Frogfoot and Octotel generally fit battery backup in their cabinets and nodes. In our experience, fibre very often stays up for roughly 2 to 4 hours into an outage, then drops when the cabinet batteries are flat. It varies a lot: some areas run all evening, while some estates drop within minutes because a building switch has no backup.
What almost always fails first is your own equipment: the ONT (the small fibre box on the wall) and the Wi-Fi router. Keep those two alive and, more often than not, your line keeps working. For a deeper look at how each network behaves, see our comparison of IPTV on Openserve, Vumatel, Vodacom and MTN fibre.
During the next outage, plug your router into a power bank or mini-UPS and note how long the fibre light stays green. Write it down. That number, not a forum post, tells you how much backup you actually need at your address.
Your load shedding IPTV power budget
Every backup decision starts with watts. We measured typical devices on a plug-in energy meter while streaming a live FHD sports channel. Your own numbers will differ by model, so treat these as realistic ranges:
| Device | Typical draw while streaming | Power input |
|---|---|---|
| Fibre ONT | ~5–10 W | 12 V DC (usually) |
| Wi-Fi router | ~8–15 W | 12 V DC (some 9 V) |
| Fire TV Stick 4K | ~3–5 W | 5 V USB |
| Android TV box | ~8–12 W | 5 V or 12 V DC |
| 43" LED TV | ~50–80 W | 230 V AC |
| 55" 4K TV | ~90–140 W | 230 V AC |
The runtime formula
We use one simple formula, with 0.85 accounting for conversion losses and the battery you should not fully drain:
Runtime (hours) = Battery capacity (Wh) / Load (W) x 0.85If a battery is labelled only in mAh, convert first: Wh = mAh x cell voltage / 1000. Most power banks and mini-UPS units rate capacity at 3.7 V, so a "10 400 mAh" unit holds roughly 38 Wh.
Worked examples
- Internet only: ONT 6 W + router 10 W = 16 W. A 38 Wh mini-UPS gives 38 / 16 x 0.85 = about 2.0 hours.
- Internet + Fire TV Stick + 43" TV: 6 + 10 + 4 + 65 = 85 W. A 512 Wh portable power station gives 512 / 85 x 0.85 = about 5.1 hours.
- Internet + Android box + 55" 4K TV: 6 + 10 + 10 + 115 = 141 W. A 1 024 Wh LiFePO4 battery on an inverter gives 1 024 / 141 x 0.85 = about 6.2 hours (slightly less once you add the inverter's own idle draw).
Backup power options compared
There is no single best option; it depends on whether you want just the internet alive (to watch on a phone or laptop) or the full lounge experience. Prices below are rough South African retail ranges and change often.
| Option | Powers | Typical capacity | Approx. price | Best for |
|---|---|---|---|---|
| DC mini-UPS (12 V/9 V dual output) | ONT + router | 30–60 Wh | ~R500–R1 200 | Most homes; keeps Wi-Fi alive 2–4 h |
| Router UPS / power bank with DC out | Router (sometimes ONT) | 20–40 Wh | ~R300–R800 | Single-box setups (router with built-in ONT) |
| Line-interactive UPS | Router, box, small TV | Short runtime, usually under 30 min at TV load | ~R1 500–R4 000 | Bridging short dips, protecting electronics |
| Inverter + LiFePO4 battery | Whole TV corner or more | 1–5 kWh | From roughly R10 000 | Frequent or long outages |
| Portable power station | TV, box, router | 250–1 000 Wh | ~R3 000–R15 000 | Renters; move it between rooms |
| Solar + battery | Household loads | Varies widely | Significant installed cost | Long-term resilience, daytime charging |
For most viewers, a DC mini-UPS is the single best value purchase. It switches in milliseconds (no router reboot), runs silently and costs less than a couple of months of DStv. Add a portable power station only if you want the big screen during long outages. Avoid cheap line-interactive UPS units for TVs: their small lead-acid batteries last minutes at 100 W, not hours.

How to check your ONT and router voltage and amps
Buying the wrong mini-UPS is the most common mistake we see. Spend two minutes on this before you order:
- Read the adapter label. Each power brick shows an output line such as
OUTPUT: 12V ⎓ 1.5A. Note the voltage (V) and current (A) for both the ONT and the router. - Calculate the maximum watts. Multiply V x A: 12 V x 1.5 A = 18 W maximum. Real draw is usually half that, but size for the label.
- Match the outputs. If the ONT is 12 V and the router is 9 V, buy a mini-UPS with both 12 V and 9 V DC ports. Plugging a 9 V router into a 12 V port can damage it.
- Check the barrel plug. Most use 5.5 x 2.1 mm plugs; good mini-UPS units ship with adapters.
- Confirm the total current. The mini-UPS should supply at least the combined amps, e.g. 1 A (ONT) + 1.5 A (router) = 2.5 A on the 12 V side.
A router that silently refuses to boot after an outage is often a 12 V port feeding a 9 V device, or a 5 V USB lead on a 12 V router. Always match the label exactly.
Switching to LTE or 5G backup during outages
When the fibre cabinet batteries finally give up, cellular is your fallback. Towers have backup too, though on long outages we have seen mobile speeds dip as everyone switches at once. Options, from simplest to most automatic:
- Phone hotspot: Share your phone's data to the TV box. Quick, but drains the phone and your bundle.
- LTE/5G router as backup: An MTN Home, Vodacom or Rain 5G router on a small UPS, joined to your TV box when the fibre drops.
- Dual-WAN router: Some routers accept a USB modem or second WAN line and fail over automatically. More setup, zero fuss during the match.
Data use matters on mobile: in our measurements an FHD sports stream used roughly 3–4 GB per hour, and SD around 1 GB. The bandwidth estimator on our homepage shows what each ISP and quality setting needs, and our network page explains why local edge nodes in Johannesburg and Cape Town keep latency low on cellular too.
Scenario: streaming a Springbok test through a 2-hour outage
Here is a realistic Saturday, based on a test we ran at home in Centurion on a 50 Mbps Vumatel line. Kick-off is 17:10 SAST; the municipal supply trips at 17:00 and comes back at 19:00.
- 17:00 — Power cuts. The DC mini-UPS (38 Wh) takes over the ONT and router instantly; Wi-Fi never drops. The TV goes dark.
- 17:02 — We switch the 43" TV and Fire TV Stick to a 512 Wh portable power station. Total load around 85 W.
- 17:10 — Kick-off on SuperSport Rugby in FHD, no buffering.
- 18:10 — Half-time check: the mini-UPS shows roughly half charge, the power station about 80%.
- 18:50 — Final whistle. The mini-UPS is close to empty after almost two hours, exactly as the formula predicted.
- 19:00 — Power returns. Nothing needed rebooting.

A word on generators
Petrol generators work but need care. Never run one indoors, in a garage or near windows: carbon monoxide kills. Cheaper open-frame units produce rough voltage that can upset sensitive electronics, so prefer an inverter generator, or put a UPS between the generator and your TV.
When power returns: reboot order and IPTV app tips
Most issues after an outage come from devices starting in the wrong order. If something is not working, follow this sequence:
- ONT first. Wait until the PON or fibre light is solid, usually 1–2 minutes.
- Router second. Wait for the internet light and confirm on a phone that browsing works.
- IPTV box or TV last. Open the app only once the network is stable.
Other habits that help:
- Cached EPG: apps like TiviMate keep the programme guide locally, so the guide still loads even if the refresh fails at first. Force an EPG update once the line is stable.
- Catch-up: on channels with catch-up, scroll back in the EPG to replay the minutes you missed during the switchover.
- Surge protection: a surge-protected plug for the TV and box is cheap insurance against spikes when power returns.
If the app shows a login error after a long outage, re-check your Xtream Codes details using our interactive setup tabs or the full TiviMate and Smarters setup guide.

Load shedding IPTV FAQ
Does load shedding still affect IPTV in South Africa?
Eskom load shedding was largely suspended through much of 2024 and 2025, but power still goes off because of load reduction in some areas, municipal substation faults, cable theft and storms. Any outage kills your router and TV, so a small backup setup remains worthwhile for load shedding IPTV viewing.
Will my fibre keep working when the power goes off?
Often, but not always. Many fibre network operators have battery backup in their street cabinets and nodes, and in our experience fibre frequently stays up for roughly 2 to 4 hours of an outage. It varies by area and by how old the batteries are, so test it during your next outage.
What size UPS do I need for my router and ONT?
Add up the wattage of your ONT and router (typically 13 to 25 W together), then use runtime = battery Wh / load W x 0.85. A DC mini-UPS of around 35 to 60 Wh usually gives 2 to 4 hours for the ONT and router alone.
Can a router UPS also run my TV?
No. DC mini-UPS units only output 5, 9 or 12 V for network gear. To run a TV and IPTV box you need an AC source such as an inverter with a LiFePO4 battery, a portable power station or a line-interactive UPS sized for the TV's wattage.
Can I watch IPTV on my phone over LTE or 5G during an outage?
Yes. Our IPTV South Africa subscription works on mobile data. HD streams use roughly 3 to 4 GB per hour, so lower the quality in the app if your data bundle is limited. Your single connection can be used on the phone while the TV is off.
Can I test streaming on backup power without a free trial?
There is no free trial. Instead every plan comes with a 30-day money-back guarantee, which gives you time to test the service on your own fibre, LTE or backup setup.
