ALL-IN-ONE, 10 KWH
Full 5 kW output and ten kilowatt-hours, 16 cm deep
The Huawei Power-M 10kWh is a complete home backup system in one cabinet: a 5 kW hybrid inverter, a built-in solar charge controller and two 5 kWh lithium iron phosphate battery modules on a single floor base. It stands about 1.09 m tall, 70 cm wide and only 16 cm deep, roughly the footprint of a slim hall table.
Two batteries is the point at which the Power-M delivers its full 5 kW. With one battery Huawei limits output to 2.5 kW; the second module doubles both the storage and what you can run at once, which is why we recommend it as the starting point for most homes.
It is sized for a family that wants the essentials to carry on through load-shedding, load reduction and municipal outages, and it grows to 15 kWh with one more battery whenever you want more hours.
I installed the Huawei Power-M at my house in 2022 when we had regular stage 6 load shedding. Having started with one battery, I later upgraded to two batteries, then added solar panels, and eventually a third battery. With the current setup, which includes eight solar panels, my house is virtually off grid. The system is installed in my dining and music room. It’s virtually silent and looks great.

HOW IT GROWS
One power module, up to three batteries a tower
The Power-M is modular. The power module on top holds the inverter, the charger and the controls, and each battery module below it adds 5 kWh. The 10kWh configuration carries two batteries, leaving room in the same tower for a third.
Adding that third battery takes the system to the Power-M 15kWh with nothing else to replace: your installer fits the Power-M 5kWh battery module under the other two, connects it and adds it in the app. Huawei allows up to six batteries on one power module, so the system can grow into a second stack later.
For more output as well as more storage, two power modules can run in parallel, as in our 10kW / 20kWh system.
QUIET ENOUGH FOR THE LOUNGE
Built to live in the room, not hidden from it
Most inverter and battery combinations end up in a garage because of how they look and sound. The Power-M was designed the other way round: a matt white aluminium enclosure only 16 cm deep, rounded corners, no visible cabling once installed, and a single round status display with a green LED ring.
Huawei rates it at 40 dBA or less at one metre, about the level of a quiet library, and it relies on natural heat dissipation rather than a fan that runs all evening. In our director’s house the Power-M shares a dining and music room with a piano, and guests rarely notice it until they ask what it is.
The modules carry an IP66 rating on Huawei’s specification sheet, so the cabinet can also go on a sheltered patio or in a garage if that suits your wiring better. It mounts on the supplied floor base or on a wall.
WHERE IT LIVES
At home in a study, a lounge or a passage
Because it is slim and quiet, the Power-M can go where your distribution board is easiest to reach, rather than where the noise and the look can be hidden. Passages, studies, dining rooms and open-plan living areas are all common.
The first two pictures show the 10kWh in typical South African rooms. The last two are our director’s own system: as it started in 2022 with one battery, and as it stands today with three.
Plan for 70 cm of wall, a little clearance at the sides for cabling, and a spot out of direct sun. Your installer will confirm the exact position against your distribution board.
SOLAR WHEN YOU’RE READY
Add panels on day one or a year later
The Power-M is a hybrid system: the solar charge controller is built into the power module, so panels connect directly with no extra hardware. Huawei rates the input at up to 5.5 kWp across two strings on one MPPT, which suits most residential roofs.
Without panels it works as a backup system, charging from the grid between outages. With panels, the sun runs the house during the day and refills the batteries for the evening, and the grid becomes the fallback rather than the main supply. Our director added panels to his own Power-M after the batteries, which is exactly how the system is designed to be used.
Everything is visible in Huawei’s FusionSolar app: battery level, solar production, what the house is drawing and where the power is coming from, at home or remotely.
MADE FOR SOUTH AFRICAN POWER
Load-shedding, load reduction and municipal outages
When the grid drops, the Power-M takes over the backed-up circuits automatically, and Huawei quotes the switchover at 0.02 seconds. Clocks don’t reset, the Wi-Fi stays up and the TV keeps playing. When supply returns it switches back and recharges.
The 5 kW output, with a 6 kW bypass, covers far more than the essentials. Our director’s 15kWh, with eight solar panels, runs everything in his house except the geyser, including the 1.1 kW pump on a 12 m lap pool. The geyser is the one load most owners leave on the grid. With solar panels up, a household that doesn’t use much electricity can fit a 2 kW PTC element on a daytime timer and let the panels heat the water through the Power-M. Without panels it isn’t worth it: the batteries would only be storing grid power to heat water.
This is Huawei’s 220 to 240 V single-phase model, supplied through Huawei’s South African distribution with a local 10-year warranty. Grey imports and on-demand overseas listings do not carry that warranty, and some are built for other markets.
What the Power-M 10kWh will run, and for how long
Two numbers decide what a backup system does for you: its output, which limits what can run at the same time, and its storage, which decides how long it lasts. The Power-M 10kWh delivers up to 5 kW from 10 kWh of usable storage. The tables below use typical South African household figures; check the rating plate on your own appliances, and your installer will size the backed-up circuits with you.
How long it lasts
| Average load | What that looks like | Runtime on 10 kWh |
|---|---|---|
| 300 W | a light essentials load: lights, Wi-Fi, TV, laptops | about 30 hours |
| 500 W | typical essentials, adding the fridge-freezer, gate and alarm | about 18 hours |
| 1 000 W | a larger home with most plugs and lights backed up | about 9 hours |
| 2 000 W | essentials plus regular kettle, microwave and appliance use | about 4½ hours |
Runtimes allow about 10% for conversion losses. If the system has had no solar input for 24 hours, Huawei keeps a 15% reserve to protect the cells, so expect a little less after a long overcast spell. With solar panels connected, the batteries refill during the day.
What it will run
| Appliance | Typical draw | On the Power-M 10kWh |
|---|---|---|
| LED lights, ten bulbs | 100 W | Yes |
| Wi-Fi router and fibre box | 20 W | Yes |
| TV and decoder | 150 W | Yes |
| Laptop | 60 W | Yes |
| Fridge-freezer (average over a day) | 150 W | Yes |
| Gate motor and alarm (average) | 50 W | Yes |
| Microwave | 1 200 W | Yes, alongside the essentials |
| Air fryer | 1 500 W | Yes, alongside the essentials |
| Kettle | 2 200 W | Yes, alongside the essentials |
| Hair dryer | 2 000 W | Yes, alongside the essentials |
| Pool or borehole pump | 1 100 W | Yes; best run in daylight on solar, since 8 hours at 1.1 kW uses 8.8 kWh |
| Oven or stove plate | 2 500 W | It can, but it draws the batteries down fast |
| Geyser element | 3 000 W | Usually left on the grid; with solar panels, a 2 kW PTC element on a daytime timer suits a low-usage home |
Most families back up the whole house on the 10kWh apart from the geyser, which is the one load that drains a battery quickly. A pool pump is fine on the 5 kW output, best run in daylight with solar panels connected, because 8 hours at 1.1 kW uses 8.8 kWh. At a typical 500 W essentials load, a 4-hour load-shedding slot uses about a fifth of the storage.

How the Power-M 10kWh sits against the alternatives
Within the range, the Power-M 15kWh has the same 5 kW output and a third battery, for long outages or a home that runs mostly on solar. The Power-M 5kWh uses the same power module with one battery, but its output is limited to 2.5 kW until a second battery is added, so for most homes the 10kWh is the sensible starting point.
The EcoFlow PowerOcean 6kW is the closest alternative we stock: also modular, in 5, 10 and 15 kWh configurations, with a 6 kW inverter against the Power-M’s 5 kW. It is the better choice if you need the extra kilowatt of output. The Power-M’s case is its slim 16 cm profile, its very quiet running and a track record in South African homes going back to 2022.
The Midea HICONICS 5kW matches the Power-M on output and adds a second MPPT for panels on two roof faces; Midea quotes 10,000 cycles at 90% depth of discharge for its CATL cells against Huawei’s 6,000 at 80%. For a small flat or a few essential circuits, the Sunsynk Powerlynk X is a compact 3.6 kW unit with 3.84 kWh of storage.
Questions we are asked about the Power-M 10kWh
Divide the capacity by what you are running and allow about 10% for conversion losses. Essentials for a typical family (lights, Wi-Fi, TVs, laptops, fridge and freezer, gate motor and alarm) average around 500 W, so 10 kWh lasts roughly 18 hours. A four-hour load-shedding slot at that load uses about 2.2 kWh, a little over a fifth of the battery.
Huawei rates each battery module at 5 kWh usable. If the system has had no solar input for 24 hours it keeps a 15% reserve to protect the cells, so plan on about 8.5 kWh in that situation.
The kettle, microwave, air fryer and a pool pump, yes. Our director’s 15kWh, with eight solar panels, runs his whole house, including the 1.1 kW pump on a 12 m lap pool; the only thing he leaves on the grid is the geyser. A standard 3 kW geyser element would empty 10 kWh in a little over three hours, so it usually stays on the grid side. If you have solar panels up and the household doesn’t use much electricity, a 2 kW PTC element on a daytime timer lets the panels heat the water through the Power-M. Without solar it isn’t worth it, because the batteries would only be storing grid power to heat water. Two Power-M units in parallel (10 kW) run a standard 3 kW element comfortably, again with the panels doing the work. An oven works, but it draws the batteries down quickly.
Yes. The solar charge controller is built into the power module, so panels connect straight to it with no separate charger. Huawei rates the input at up to 5.5 kWp across two strings on one MPPT, within a 90 to 420 V DC window, and it supports up to eight Huawei optimisers. In practice that is roughly eight to ten modern panels per power module, depending on their wattage and how your installer strings them.
Plenty of owners start with backup only and add panels a year later. Nothing on the Power-M changes when you do; your installer runs the cables to the PV input and enables solar in the app.
Yes. The tower has room for a third Power-M 5kWh battery module, which takes the system to 15 kWh with the same 5 kW output. Huawei allows up to six batteries on one power module; beyond three, a second stack starts beside the first. Your installer fits and connects the new module and adds it in the app.
Yes. It is wired into your distribution board, so it must be installed by a qualified electrician who issues a Certificate of Compliance. We supply the equipment and refer you to experienced Power-M installers in most areas of South Africa; the installer quotes and carries out the work, and is responsible for it.
You can also use your own installer. They supply the cabling, isolators, changeover switch and earth leakage, then commission the system and connect it to your Wi-Fi through Huawei’s FusionSolar app.
Huawei rates the modules IP66 (its 2021 brochure says IP65), and the cabinet is approved for indoor or sheltered outdoor installation, on the floor or on a wall. It runs between 0 and 45 °C. Huawei’s South African installation guide asks for a spot out of direct sun and rain, away from taps, drains and sprinklers, and rules out outdoor installation within 500 m of the sea, where salt air corrodes the enclosure. Indoors, at the coast, is fine.
Because it is rated at 40 dBA or less at one metre, most owners put it inside: a passage, a study, a dining room or the garage.
Fast enough that lights, TVs, Wi-Fi and laptops carry on without a flicker in normal use. Huawei’s own marketing material quotes 0.02 seconds. Its published specification sheet does not list a transfer time, so we give that figure as Huawei’s rather than our own measurement. If you run something that cannot tolerate any interruption at all, such as a server, keep a small UPS in front of it as well.
The Power-M carries Huawei’s 10-year warranty, supported in South Africa through Huawei’s local distributor. If a module develops a fault, contact us with your order number: we log the claim, follow it up and keep you informed until it is resolved.
The warranty covers the equipment. Faults caused by the installation itself, such as wiring or protection errors, are the installer’s workmanship and are taken up with them, which is one reason a Certificate of Compliance matters.
Fake online stores have advertised the Power-M at prices no genuine seller can match, then disappeared with the payment. EcoHub has sold Huawei backup systems since the Power-M arrived in South Africa in 2022 and has traded as an online store since 2012. Our stock comes through Huawei’s South African distribution, which is what makes the local warranty valid. If a price looks too good to be true, check the seller’s history before you pay.
Yes. You can collect from our Kempton Park warehouse or have it delivered; choose at checkout and the delivery cost is shown before you pay. Each battery module weighs about 50 kg and the power module about 17 kg, so this system weighs about 119 kg before packaging. Bring a second person, or have your installer collect it.
