Please consult the certification file here.

Yes, thanks to its plug-and-play design, the SolarFlow 2400 AC is designed for easy installation by the user.

SolarFlow 2400 AC supports charging the battery from the home grid, making it ideal for two household scenarios:

1. Homes with installed balcony or rooftop PV systems but without storage batteries.
SolarFlow 2400 AC stores solar energy generated during the day for later use, reducing electricity costs.

2. Dynamic electricity pricing scenarios.
The battery charges during low-tariff periods and discharges during peak hours, enabling self-sufficient energy use and reducing grid electricity purchases.

No, SolarFlow 2400 AC cannot connect to PV panels but can be used as a storage system for existing PV system.

Yes, SolarFlow 2400 AC requires a smart meter to monitor household power usage in real time and determine its charging/discharging status and power. Example: If the smart meter detects that your existing PV system is exporting power to the grid, charging will be activated.
If 800W of excess energy is detected, SolarFlow 2400 AC will charge at 800W.

When the SolarFlow 2400 AC System detects that the household requires grid power and the battery has sufficient charge, it will automatically initiate discharge.
Example: If 600W is needed, SolarFlow 2400 AC will discharge at 600W to meet the household demand.
Supported smart meter models:  Zendure Smart Meter 3CT, Zendure Smart Meter D0 (Germany), Zendure Smart Meter P1 (Netherlands), Shelly Pro 3EM, Shelly 3EM.

Yes, SolarFlow 800 Pro’s plug-and-play design makes installation easy for users.

SolarFlow 800 Pro optimizes your home energy usage with a combination of high-performance hardware and an AI-powered HEMS (Home Energy Management System), making your energy consumption smarter and more cost-efficient.

High-Performance Hardware: Equipped with a 2640W (4×660W) MPPT controller and a 1000W bidirectional inverter (1000W input & off-grid output, 800W grid-tied output), SolarFlow 800 Pro efficiently stores excess solar energy during the day (when paired with a battery) and supplies power to your home at night, reducing overall energy costs.

AI-Powered HEMS: Utilizing advanced AI algorithms, SolarFlow 800 Pro analyzes your solar generation, consumption patterns, weather forecasts, and electricity price fluctuations to dynamically adjust daily charging and discharging schedules. It charges at lower rates during off-peak hours (e.g., nighttime) and switches to battery power during peak hours, optimizing energy use and achieving up to 42% energy cost savings.*

*This data is based on Zendure lab tests under a dynamic electricity pricing model. Actual savings may vary depending on local electricity rates, system configuration, and household energy consumption habits.

1. Calculate annual energy generation: Select your location and the installed capacity of the solar system on the map. Combine the solar altitude angle, azimuth angle, and the tilt angle of the solar system to get the annual energy generation of the system.

2. Save on electricity bills: Annual savings (kWh/year) = Annual energy generation (kWh/year) × self-consumption rate × electricity price in Germany.
For example, using SolarFlow 800 Pro in Southern Germany with 2000W PV module and a smart meter:
Annual savings = 2260 kWh/year × 98% × 0.4€/kWh = 880€

Electricity prices vary by region and time, and our estimated electricity price may not reflect your actual cost. This may affect the final electricity cost calculation.

Grid safety requirements: Maintaining grid monitoring and protection functions

The grid-tied inverter must continuously monitor the grid status to comply with international and national safety standards (e.g., VDE-AR-N 4105 in Germany and UL 1741 in the United States).

Even when the inverter stops supplying power to the grid, it needs to remain in a low-power standby mode to monitor the grid’s status and detect when it becomes stable again. Once the grid is stable, the inverter can automatically restart and synchronize with the grid.

If the inverter were to completely power off, it would not be able to detect the grid status, potentially leading to delays in grid reconnection or incorrect operation when the grid recovers.

It uses a "striped housing" design for rapid heat dissipation, and its aluminum casing makes it lighter and more resistant to corrosion.

With a total 1200W MPPT controller and an 800W bidirectional inverter, SolarFlow 800 stores surplus solar energy (when a battery is installed) during the daytime and powers your home at night, reducing overall energy costs.

With time-of-use pricing, SolarFlow 800 automatically switches to battery power during peak-rate periods and recharges the battery during off-peak hours (such as overnight) to enable self-powered operation during high-demand daytime hours. This dual approach ensures continuous savings while maintaining energy independence.

1. Calculate annual energy generation: Select your location and the installed capacity of the solar system on the map. Combine the solar altitude angle, azimuth angle, and the tilt angle of the solar system to get the annual energy generation of the system.

2. Save on electricity bills: Annual savings (kWh/year) = Annual energy generation (kWh/year) × self-consumption rate × electricity price in Germany.
For example, using SolarFlow 800 in Southern Germany with 1000W PV module, one AB2000S battery, and a smart meter:
Annual savings = 1130 kWh/year × 98% × 0.4€/kWh = 440€

3. Save CO2: Saving 1 kWh of electricity = saving 0.997 kg of CO2.
The results may vary from actual usage due to factors such as weather, daytime hours, installation location of the modules, and others, which may lead to different results. Electricity prices vary by region and time, and our estimated electricity price may not reflect your actual cost. This may affect the final electricity cost calculation.
