1. Why Do More and More Households Need “Flexible” Energy Storage Devices Now?
Recently, when I talked to friends about home energy storage, I found that everyone shares the same pain points: some think traditional energy storage boxes take up too much space—balconies are already small, and after placing a washing machine, there’s no room left for drying clothes if you add a large device; others complain about complicated installation—you have to find an electrician, wait for the schedule, and even drill holes in the wall for wiring, which is a shame for newly decorated houses; still, some worry about “not understanding the status”—not knowing if the stored electricity is enough, or failing to spot equipment issues in time.
In fact, these problems stem from the fact that traditional energy storage devices are “not well-adapted to home scenarios”. It wasn’t until I came across this “dual-purpose floor-standing & wall-mounted all-in-one home energy storage inverter” that I realized home energy storage could be “flexible, hassle-free, and trouble-free”. Today, from a practical user perspective, I’ll talk about how this device solves these problems, and how ordinary households can choose and use it.
2. Core Advantage 1: Dual-Purpose (Floor-Standing & Wall-Mounted) – Even Small Apartments Can “Squeeze Out” Space for Energy Storage
For most households, “space” is the first hurdle when choosing energy storage devices. My neighbor lives in a typical old and small apartment, with a balcony only 1.5 meters wide. The floor-standing energy storage device he looked at earlier was nearly 1 meter wide—after placing it, there was no space left for the robot vacuum. On the other hand, pure wall-mounted devices have too small capacity to power the air conditioner at night.
This all-in-one unit hits the “flexibility” sweet spot: its body is designed to be compact, only 18cm thick. When mounted on the balcony wall, it doesn’t block window light at all; if you have a garage or storage room, placing it on the floor in the corner also takes up no space—my cousin placed his next to the tool cabinet in the garage, and you barely notice it unless you look closely.
What’s more thoughtful is that its wall-mounted bracket uses a hole-free design, fixed with strong adhesive and expansion screws. No need to drill large holes in the wall, so even renters can install it (you can take it down when moving). Whether it’s floor-standing or wall-mounted, there’s no need to reserve “operation space” specially. The side of the body has heat dissipation holes, so normal ventilation is enough for it to work. Small spaces like balconies, corridors, and garage corners are all suitable.
The key point is “no capacity compromise”—despite its small size, its energy storage capacity ranges from 10kWh to 20kWh. A 10kWh unit is enough for an average family of three: store solar energy during the day, and use it to power the air conditioner, TV, and charge phones at night. If you need to emergency charge an electric vehicle at home, a unit with 15kWh or more can meet that demand.
3. Core Advantage 2: Integrated Energy Storage & Inverter – Save Money and Reduce Malfunctions
Many people are confused by the two terms “energy storage battery” and “inverter” when choosing energy storage devices for the first time. Simply put, an energy storage battery is for “storing electricity”, and an inverter is for “converting the stored DC power into AC power usable by home appliances”. Traditional devices require separate purchase and installation, which not only costs extra money but also risks “incompatibility” between the two.
This all-in-one unit integrates both functions directly—equivalent to “buying one device and getting two functions”. I did the math for a friend: buying a 10kWh energy storage battery and a 3kW inverter separately costs about 2,000 yuan more; the price of this all-in-one unit is roughly 20% lower than the total of the two separate devices, and you also save the labor cost for wiring.
More importantly, it’s “highly reliable”. My cousin, who repairs home appliances, told me that the most error-prone part of traditional separate systems is the “wiring connections”—oxidation or looseness can cause power outages or even equipment burnout. However, this all-in-one unit is pre-adjusted by the manufacturer, with internal wiring sealed. No post-installation wiring is needed, reducing the malfunction risk by at least half.
I also noticed that its shell is made of flame-retardant ABS material. Even when the balcony temperature exceeds 35°C in summer, the body only feels slightly warm, not hot like some devices with plastic shells. It also has internal overcharge, over-discharge, and short-circuit protection—even if you accidentally touch the power cord, there’s no safety hazard, which is crucial for families with children.
4. Core Advantage 3: Real-Time LCD Monitoring – Even Elderly Family Members Can Understand “Device Status”
“I don’t know if the device is working” or “if the stored electricity is enough”—these were my mom’s biggest worries before. Traditional energy storage devices either have no display screen or require connecting to a mobile app to check. Elderly people who aren’t familiar with smartphones can only “guess”.
This all-in-one unit has a 5-inch LCD screen on the front. No internet connection is needed—you can see real-time data as soon as it’s turned on: the left side shows “remaining power” (displayed with a percentage and icon, as intuitive as a phone’s battery), the middle shows “current output power” (e.g., 1.5kW when the air conditioner is on), and the right side shows “operation status” (a green light for normal operation, a red light plus prompt text for issues, such as “unstable voltage”).
Now my mom checks it every morning: if the remaining power is over 70%, she knows she can use the air conditioner freely at night; if she sees a red light, she calls me, and I can solve the problem by consulting customer service remotely—no need to call a technician for on-site inspection, saving a lot of trouble.
Another thoughtful detail: the screen brightness adjusts automatically—it gets brighter in strong sunlight during the day and doesn’t glare at night, so placing it near the bedroom door won’t affect sleep. Unlike some devices whose screens are either unreadable due to reflection during the day or as bright as a small desk lamp at night.
5. Core Advantage 4: Plug-and-Play Installation – Set It Up Yourself in Half an Hour
“Complicated installation” is the main reason many people give up on energy storage devices. I once helped a colleague install a traditional energy storage system—it took 3 days just to wait for the electrician. During installation, we had to disassemble the balcony socket and rewire, making the house dusty, and finally paid 500 yuan for labor.
This all-in-one unit features a “plug-and-play” design. I tried installing it at home myself, and it took less than half an hour from unpacking to using it: Step 1, fix the bracket (for floor-standing or wall-mounted use); Step 2, snap the device onto the bracket; Step 3, plug in the power cord (as simple as plugging in a washing machine); Step 4, connect it to the home’s main socket—done.
No need to modify the circuit, no complicated wiring, and you don’t even need to read a circuit diagram. The instructions have step-by-step pictures and text, such as “Step 1: Unscrew the bracket screws” and “Step 2: Plug in the blue power cord”. Even my dad, who can’t use a smartphone, can install it by following the instructions.
If you’re really unsure, the manufacturer also provides “remote guidance”—make a call, and the customer service will send a video tutorial to guide you step by step. No need to pay for a technician. My friend, who rents an apartment, took his device down when moving and reinstalled it in the new home in 20 minutes. His landlord even praised him for “choosing a good device that doesn’t damage the wall”.
6. Core Advantage 5: Customizable Design – Not Only Practical but Also “Good-Looking”
Traditional energy storage devices only come in black or gray, which look very out of place at home—my neighbor’s previous black device looked like a “patch” on his white wall. This all-in-one unit is different: it offers customizable colors, such as white, beige, and light gray, and can even match the color of your home walls.
For small businesses like convenience stores or small supermarkets, you can even print your brand logo on the body—there’s a convenience store downstairs from my house that installed one with its store name printed on it. It’s both practical and serves as advertising, killing two birds with one stone.
Capacity customization is also flexible: you’re not limited to fixed options like 10kWh or 15kWh. Instead, you can adjust it based on your electricity needs. For example, my uncle in his hometown only uses electricity for the refrigerator, lights, and router. The manufacturer customized an 8kWh unit for him, which is 1,000 yuan cheaper than the standard model. My colleague, whose family has two air conditioners and a washing machine, got a 20kWh customized unit—it can power the entire family for 3 days during summer power outages.
The customization process is also simple: tell the manufacturer’s customer service your needs (color, capacity, logo), they will send a design draft, and after confirmation, the product will be shipped in about a week—no delay in use.
7. Practical Use Cases: How Do Different Households Use It?
1. Small Urban Apartment (Family of Three)
My colleague Xiao Li lives in a small 60-square-meter apartment with a 1.2-meter-wide balcony. He chose the 10kWh wall-mounted model in white, installing it next to the washing machine on the balcony. He stores solar energy during the day and uses it to power a 1.5-ton air conditioner, TV, and charge phones at night. The remaining power is about 30%, which is enough for the next morning. His monthly electricity bill is nearly 100 yuan lower than before, and during power outages, the router and lights still work—no more sitting in the dark.
2. Rural Self-Built House (Family of Five)
My cousin lives in a rural self-built house where power outages are common. He chose the 15kWh floor-standing model, placing it in the garage. He stores solar energy on a daily basis, and during power outages, it can power the refrigerator, washing machine, and rice cooker—even for emergency charging of electric bikes. Last summer, there was a 2-day power outage, and his family still cooked and watched TV as usual. Neighbors even came to borrow electricity—the best part is, there’s no need to buy a generator like before, which is noisy and uses fuel.
3. Renter (Single Person)
My friend Xiao Zhang rents an apartment. He chose the 8kWh wall-mounted model with a hole-free installation. He usually uses it to charge his laptop and phone, and power a desk lamp and router at night. His monthly electricity bill is over 50 yuan lower. He took it down when moving and reinstalled it in the new home in 20 minutes. His landlord praised him for “choosing a great device that doesn’t damage the wall”.
8. Buying Tips: Don’t Just Focus on Advantages – Avoid These 3 Pitfalls
1. Don’t Blindly Choose a Large Capacity
Bigger capacity isn’t always better—it depends on your home’s electricity usage: a 10kWh unit is enough for basic needs (lights, TV, phones); choose 15kWh or more if you have an air conditioner, washing machine, or water heater; and at least 20kWh if you need to charge an electric vehicle. A too-large capacity wastes money, while a too-small one won’t meet your needs.
2. Always Check Safety Certifications
Genuine products must have 3C certification (for China) or CE certification (for exports). Avoid “three-no products” (no brand, no certification, no manufacturer). A friend of mine once bought an uncertified device to save money—it had an overcharge issue after 6 months. Fortunately, he noticed it in time, avoiding a safety accident.
3. After-Sales Service Matters
Energy storage devices are used long-term, so choose a manufacturer with good after-sales service: look for a warranty period (preferably 5 years or more), 24/7 customer service, and on-site repair services. If the device has a problem, you can get it fixed promptly without dealing with it alone.
