Zendure SolarFlow 2400 AC Solar Battery: Smart Power and Everyday Security
From the very first installation, the Zendure SolarFlow 2400 AC is easy to set up, but what's really striking is the finesse of its technical design. Every detail seems designed for modern, demanding residential use.
There's a grounding port, a Wi-Fi 5 antenna for a reliable connection, and even Bluetooth for flexible control. A small jack allows you to connect an external fan, although honestly, the integrated fins are more than enough to keep the module cool.
A word of warning for the curious: despite its IP65 certification, which protects the battery from rain and dust, direct heat remains its enemy. Installing the case in the shade, with a distance of about 15 cm from a wall and free ventilation, guarantees optimal dissipation and extends its lifespan.
Winter is no problem: the battery is self-heating. As with electric vehicles, cold weather can reduce the capacity of lithium batteries, but the built-in heating function helps maintain stable performance even in harsh weather.
When it comes to safety, Zendure leaves nothing to chance. An aerosol protection system activates in the event of thermal runaway, providing reassuring passive safety for home use.
The small, simple but effective front display shows at a glance the charge level, Wi-Fi status and system notifications, making daily monitoring easy.
With an individual capacity of 2.88 kWh per AB3000X module, expandable up to 17 kWh by stacking six units, the SolarFlow can even scale up to 51.8 kWh with three complete kits. Enough to power an entire household or an off-grid installation for several days, without compromise.
The only limitation is the lack of an RJ45 port. You will therefore need to ensure solid Wi-Fi coverage to fully exploit the management application.
In summary, the Zendure SolarFlow 2400 AC combines intelligence, robustness and flexibility , with particular attention to safety and performance, winter and summer. A complete solution for anyone who wants reliable and scalable solar storage.
Zendure SolarFlow 2400 AC Solar Battery Immersive Test: Express Installation and Smart Energy Management
From the moment you unbox it, you can tell that Zendure has thought through the user experience down to the smallest detail. Installation is surprisingly simple: there's no need to modify your existing panels, regardless of their number or power. Once plugged in, the SolarFlow 2400 AC automatically detects excess energy or the home's needs, as if it "guessed" your habits.
Two impressive energy management modes
1. Shelly Smart Meter
During our test, we connected the SolarFlow to a Shelly meter on the main circuit breaker. Thanks to its current clamp, the battery receives consumption data in real time. The result: a 1,050 W excess instantly triggers a 1,000 W charge. The responsiveness is impressive. Installation remains simple and compatibility with other equipment is complete, a real plus for homes already equipped.
2. Zenki Mode (proprietary Zendure algorithm)
Zenki, the in-house artificial intelligence, continuously analyzes consumption, household habits, weather conditions, and even variations in electricity prices. In our test scenario, an excess production of 1,000 W was detected. When the pool pump started, the battery took over immediately. A few minutes later, the oven was activated (2,600 W): the SolarFlow injected up to 1,200 W, the rest being supplemented by the EDF network. This perfectly orchestrated ballet between solar production, consumption, and the network illustrates the sophistication of the system. The icing on the cake: Zenki will remain free, although it was initially planned as a paid option.
Some limitations to be aware of
During rapid changes, such as a cloud passing in front of the sun or the sudden switching on of a very energy-intensive device, Zenki can exhibit a slight inertia. This can result in brief exports to EDF or a small recourse to the grid before the battery adjusts the flow. Nothing critical, but it shows that, like any intelligence, the system takes a moment to “think.”
Precise monitoring and control
The Zendure app perfectly complements the system. Its dashboard offers detailed monitoring: charge and discharge cycles, grid inputs, self-consumption share, etc. Everything can be viewed daily, weekly, monthly, or even annually. You truly feel in control of your energy, with precise and intuitive control.
Advanced features for customized management of the SolarFlow 2400 AC battery
Thanks to its direct connection to an electrical outlet, the SolarFlow 2400 AC is perfectly suited to electricity contracts with peak/off-peak hours (such as Tempo or traditional offers). You can schedule charging during off-peak hours (for example, from midnight to 6 a.m.), then redistribute this energy in the morning, a period often requiring electricity. This function is accessible via the charge and discharge settings of the Zendure application.
The SolarFlow 2400 AC battery also stands out in off-grid . Its electrical outlet allows it to be recharged directly from a microinverter connected to a solar panel, without going through the grid. During our test, a single panel injected 316W into the battery, confirming its ability to operate in complete autonomy. A small downside: when the battery is fully charged, it automatically disconnects from the grid and requires manual reactivation via the app to continue powering devices.
This off-grid outlet offers an interesting dual functionality: it can both power appliances and receive electricity from your microinverter. We tested a 1,000W heater plugged into the battery powered by a solar panel. The heater operated without interruption, with the power coming partly from the solar panel and partly from the battery. Even with a 2,000W load, the battery held up without difficulty, absorbing consumption spikes. This is a nice surprise that underlines the SolarFlow battery's ability to simultaneously manage on-grid and off-grid operation.
Additional operating modes
“Smart plug” mode : Paired with a connected plug, the battery detects the consumption of a connected device (e.g. television) and automatically powers this device.
“Manual” Mode : For users who want total control, this mode allows you to manually set the charging and discharging time slots.
“Electricity Tariff” mode : Currently under development, this mode is intended to exploit price variations between peak and off-peak hours. Currently, it only allows you to define high and low tariffs, without yet managing the specific ranges of Tempo contracts, an improvement expected by Zendure.
Our ideal scenario
For optimal management, the objective would be to:
Recharge the battery at night, during off-peak hours, at a competitive rate
Use the battery in the early morning, before sunrise
Automatic switch to solar panels during the day, storing surplus power
Then draw on the battery to power energy-consuming devices (e.g. swimming pool pump) in the evening
Profitability: a long-term strategic investment with the SolarFlow 2400 AC battery
Profitability depends on many factors, but let's take a concrete example. For a configuration with a single AB3000X (2.88 kWh) combined with the complete kit with Shelly and the SolarFlow 2400 AC battery, the cost is around €1,500 .
Considering a useful use of 90% of the capacity (i.e. approximately 2.59 kWh to preserve the battery) and an average EDF tariff of €0.21/kWh, we can estimate a daily saving of approximately €0.50 . Over a year (365 days), this represents approximately €182 in savings .
With a lifespan of around 16 years (6,000 cycles, assuming one cycle per day thanks to off-peak management), the total savings would reach almost €2,700 , thus largely covering the initial cost. The return on investment would therefore be around 8 to 9 years . This figure is typical for energy storage solutions, even if the SolarFlow 2400 AC battery is not specifically optimized for small installations.
Optimizing profitability with multiple batteries
The full potential of the SolarFlow battery is further revealed by adding additional batteries and having a significant solar production. For example, with six batteries , the total cost of the system would be approximately €5,500 , but the estimated lifetime savings would reach €16,400 .
This brings profitability down to a 5-year , which is significantly more advantageous.
For smaller installations, the SolarFlow 800 may be a more suitable alternative.
Tips for optimal sizing
It's essential to accurately assess your annual energy needs and take your geographic area into account, as solar production varies greatly between the North and South of France. This analysis will help you choose the ideal size for your SolarFlow battery installation.
Simplified installation: Quick and easy assembly.
Complete and scalable kit: Add batteries for more autonomy.
