There are many portable power stations on the market today. They all look a bit similar. But the LANPWR 2400 PRO represents an interesting advancement in this field: it's not just a backup battery, but a true balcony solar system with an integrated microinverter. The LANPWR 2400 PRO stands out from other power stations due to its ability to feed stored electricity directly into your home network. This is where its uniqueness lies! Unlike traditional systems that require an external microinverter, this one is integrated directly into the station. This all-in-one approach considerably simplifies installation and reduces overall costs. I've had the opportunity to test this product for several months now, and it's time to share my impressions of this solution that promises to save on your electricity bills while providing you with energy autonomy. Unboxing the LANPWR 2400 PRO The packaging leaves no mystery about the product, which is clearly labeled: LANPWR 2400 PRO The back highlights the various uses: As soon as you open the box, you're struck by the device's impressive dimensions. The LANPWR 2400 PRO measures approximately 46 x 26 x 30 cm and weighs 23 kg. It's far from lightweight, but the two sturdy handles make it easy to transport over short distances.
In the box, you'll find:
The LANPWR 2400 PRO power station
An MC4 adapter cable for connecting solar panels
An MC4 adapter for connecting up to four solar panels
A cable for charging via the cigarette lighter
- Two user manuals (one for the station and one for the app)
- The station's design is understated and functional, with a predominantly beige color that blends discreetly into any interior. The build quality appears solid, even though the device isn't tropicalized and should therefore not be exposed to humidity or the elements.
- The front panel is particularly well-designed, with a central LCD screen clearly displaying essential information: battery level, input and output power, remaining usage time, and activated outputs. On either side of this screen are the various ports and control buttons.
- On the left, the USB ports include two QuickCharge 3.0-compatible USB-A ports and two USB-C ports (27W and 100W).
- In the center, we find the DC outputs with a 12V cigarette lighter port and two 12V jack outputs.
- On the right, three Schuko power outlets (German standard, compatible with 99% of our devices) deliver 230V at 50Hz. The most interesting button is undoubtedly the one marked “MIG-OFF-GRID,” which activates the power reinjection function into the home grid. This is the flagship feature of this station, and it's accessible with a simple press.
There are large vents on each side, and two handles for easier carrying of the battery.
It's always nice to be able to easily carry this type of equipment, because 23kg can be felt :)
On the right side, we find the power socket, which will also be used for reinjection, as well as an input for the solar panels.
Be careful, as you can see, the power socket here is a bit unusual; it's not the standard cord usually found on this type of equipment:
So be careful not to lose it!
Installing the LANPWR 2400 PRO
Installing the LANPWR 2400 PRO is disconcertingly simple, and this is one of its main advantages. No need for an electrician or complex work – it's true plug-and-play!
For basic use as a portable energy station, simply charge it fully before first use. To take full advantage of all its features, including electricity reinjection, you must install the Wonderfree mobile application, available for free on iOS and Android.
After creating your account, simply ask to add a device. The application will scan surrounding devices.
We enter the WiFi network, and the battery is added to our account, and accessible even remotely.
The application allows you to monitor the status of the station in real time, schedule charging and discharging periods, and adjust the reinjection power. The connection is via Wi-Fi (2.4 GHz only), and the pairing process is quick and easy. The interface is correctly translated into French, which is appreciated.
From the interface it is possible to activate the outputs (230V, Usb, etc.), or on the contrary start charging the battery from the sector, even indicating at what power. Even the LED lighting can be controlled from the interface.
For use with solar panels, two configurations are possible:
Use the LANPWR 2400 PRO as a complement to an existing balcony solar panel system. In this case, the station charges via the mains socket which already receives electricity from your panels, then can return it as needed. This is the type of operation that we were able to see in particular with the
Zendure Hyper 2000
.
Connect solar panels directly to the station using the provided MC4 adapters. This method is more efficient because it avoids an additional conversion, but requires a slightly more complex installation with a window feed-through for the cables.
The station accepts solar input voltages from 18 to 145V, allowing for different panel configurations. The manual suggests several possible combinations, such as four 30V/180W panels (two in parallel and two in series) or two 36V/550W panels in series.
In Use: Impressive Versatility
- I tested the LANPWR 2400 PRO in a variety of situations, and it performed well in all of them. Let's start with its primary use: solar energy storage and reinjection. Solar Balcony ModeThe integrated microinverter feature is what really sets this station apart from others. I configured the station to charge during the day via my solar panels, then reinject the stored electricity in the evening, when my consumption is higher but the panels are no longer producing.
- The reinjection power can be adjusted in 50W increments, between 100 and 800W, which offers significant flexibility. For example, I scheduled a 300W reinjection between 6 p.m. and 10 p.m., a time when we use several devices simultaneously. The app allows you to create custom scenarios and program precise time slots, down to the minute.
A particularly interesting feature: the station can be configured to only start reinjecting when the battery reaches 95% charge, and to stop when it drops to 10%. These thresholds can be modified in the app, allowing you to optimize usage according to your specific needs.
In terms of savings, I noticed a significant reduction in my grid electricity consumption. On a sunny day, the station can store up to 2kWh of energy, which is then used when needed rather than being “given” to the grid for free.
Emergency Mode
The LANPWR 2400 PRO also excels as a backup solution in the event of a power outage. With its 2200W of continuous power, it can power most essential appliances: refrigerator, lighting, medical equipment, etc.
I simulated a power outage by disconnecting the main circuit breaker, and the transition was seamless. The devices connected to the station continued to operate without interruption. With its 2040Wh capacity, it can power a refrigerator for over 29 hours, an internet box for over 85 hours, or charge a smartphone approximately 174 times!
1866 Wh, no worries! An important detail: in the event of a power outage, the reinjection function automatically stops for safety reasons, but the station continues to power the devices directly connected to it. If you want to power the entire house, there will be no other choice but to use a power inverter, as we have seen for other models. Unfortunately, there's no alternative; it's a safety measure.
Camping/Outdoor Mode
I also tested the LANPWR 2400 PRO during a camping weekend. Its ability to simultaneously power multiple devices (electric cooler, lighting, phone and laptop charging) makes it a valuable travel companion for those who don't want to give up electrical convenience.
The presence of an integrated LED light with an SOS function is a welcome addition for outdoor use. The noise level is remarkably low for a station of this power—at less than 400W of load, it's practically inaudible. It's only above 600W that the fan noise becomes truly noticeable.
I particularly appreciated the pass-through charging feature, which allows the station to be used while charging. This came in handy when I connected a small portable solar panel during the day while continuing to use the station to power my devices.
The Wonderfree App
The timer programming works perfectly, allowing you to set charging and discharging periods according to your needs. For example, the station can be programmed to charge during off-peak hours and reinject during peak hours, maximizing savings, even without solar panels. These programming options make it very useful for Tempo red days, when peak hours are prohibitively expensive: it's possible to program the battery to charge during off-peak hours, then to release this electricity during peak hours. Example here: activate “AC Charge” from 10 pm to 6 am, with a power output of 400 W, which will charge the battery overnight during off-peak hours. Then activate the “MIG Timer” option from 6:10 am to 9:55 pm, with a power output of 250 W. The battery will therefore reinject 250 W into the home circuit during peak hours (which roughly corresponds to my consumption benchmark). The “magical” thing about this battery is that you simply plug it into a standard electrical outlet at home. Once the timers are set in the app, it charges and discharges automatically without any intervention. The system works so well that I used it not only on peak days, but every day this winter, which allowed me to live almost exclusively during off-peak hours despite the terrible weather we've been having.
You can set it in a corner and forget about it once it's programmed.
The app also provides statistics on the energy produced, stored, and reinjected, allowing you to track the system's efficiency over time. The French translation is accurate, although some technical terms are sometimes in English.
One small drawback: the app requires an internet connection to work, even if the station is connected to local Wi-Fi. It would have been nice to be able to use it in offline mode for camping or internet outages. Performance and Battery Life
In terms of performance, the LANPWR 2400 PRO delivers. The 2040Wh capacity provides a comfortable battery life for most household uses. Here are some concrete battery life examples:
70-inch LED TV: over 11 hours
Refrigerator: over 29 hours
Microwave (1100W): approximately 1.5 hours
Laptop: 34 full charges
LED lighting: 174 hours
Charging is also fast: in boost mode (1500W), the battery fully charges in 1.5 to 2 hours. In normal mode, it takes 4 to 5 hours, and in eco mode, 6 to 7 hours. With 1200W solar panels on sunny days, the station can reach 80% charge in just 2 hours.
One point to note: like all batteries, the LANPWR 2400 PRO's performance is affected by extreme temperatures. It operates optimally between 0°C and 40°C when charging, and between -10°C and 40°C when discharging. For winter use, it's therefore best to keep it indoors. However, it's not designed for sleeping outside.
Conclusion: An innovative solution that delivers on its promises
The LANPWR 2400 PRO represents a truly exciting advancement in the field of portable power stations. Its integrated microinverter sets it apart from the competition and makes it a particularly attractive solution for those looking to optimize their solar energy consumption (or not) without complex installation. Typically, you need a battery, which is connected to a microinverter, as we saw, for example, between an Ecoflow Delta Pro 3 battery and a Powerstream. There's no complicated assembly here; just plug in a simple electrical outlet, and that's it. And in practice, it's a small revolution!
- Its strengths are undeniable: plug-and-play installation without an electrician, generous storage capacity, high output power, and, above all, the ability to feed electricity back into the home grid. The well-designed mobile app allows for precise energy management according to your specific needs.
- A few areas could be improved, such as the lack of weatherproofing (it's not suitable for permanent outdoor use), the significant weight that limits its portability, and the reliance on the app for certain advanced settings. Another notable drawback is the lack of wireless charging for smartphones, a feature that has become commonplace on high-end stations.
- In terms of value for money, the LANPWR 2400 PRO is well-positioned on the market. Its price of
- approximately €1,080 (using the discount code
- NNNFRLP22PP
)
may seem high for a portable power station, but considering the integration of the microinverter (which would cost several hundred euros separately), it's a very competitive offering. Furthermore, the savings on the electricity bill will help recoup this investment in the long run. In short, the LANPWR 2400 PRO is, for me, a versatile solution that meets several needs: optimizing solar self-consumption, providing backup power in the event of a power outage, and providing a portable power source for outdoor activities. If you're looking for an all-in-one solution for these different uses, it's certainly worth your consideration. In any case, it's a model I really like, and it's easy to wonder why all the competitors don't integrate this microinverter component into their batteries!
Note that the battery is also available in a pack with one or two 400W solar panels, which will allow for relatively self-sufficient electricity:
