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.

Each MPPT input supports a maximum power of 660W, with an open circuit voltage (Voc) below 55V. Since solar panel output can vary significantly depending on weather conditions, it is recommended to connect solar panels with a power rating up to 1.5 times the MPPT's nominal power to ensure optimal performance.

Yes, as long as the operating voltage is between 14V and 55V. Do not exceed 55V to avoid permanent damage.

Yes, you can connect 2-3 panels (100W-350W each) in parallel on each solar connector. Ensure that the voltage of the panel array is between 14V and 55V.

It supports Zendure AB1000/AB2000/AB1000S/AB2000S/AB2000X batteries. You can mix AB1000 and AB2000 series batteries, with up to 5 additional stacked units, for a total capacity of up to 11,520Wh.

No, AB1000/AB1000S/AB1000X/AB2000/AB2000S/AB2000X are not compatible with AB3000X.

Yes, the SolarFlow 800 Pro system automatically schedules AC charging during off-peak hours via the Zendure APP for cost savings. Moreover, it auto-switches to AC charging mode using grid power when battery levels are critically low with poor PV generation, preventing potential battery damage.

Yes, it has one off-grid socket, with a peak power of 1200W (10s) and a stable maximum output of 1000W. The off-grid function must first be enabled in the app. Once activated, SolarFlow 800 Pro can seamlessly switch to battery power within 15ms during a grid outage, ensuring continuous operation of devices connected to the off-grid interface.

According to EU safety regulations, the SolarFlow 800 Pro will stop supplying power to the grid during a power outage.

However, you can use the off-grid outlet during power outage with max 1000W power.

Yes, it supports simultaneous use of off-grid and grid-tied functions, with a total power output not exceeding 1000W.

When using only the off-grid function, the off-grid AC interface has a maximum discharge power of 1000W.

Thanks to third-generation GaN semiconductor technology, energy loss is significantly reduced, enhancing overall energy storage efficiency.

On rainy or foggy days, solar power generation is significantly reduced, but the solar panels will continue to operate at a much lower efficiency. With batteries, you can store excess solar energy or charge them cheaply during off-peak hours to ensure uninterrupted power supply. This smart energy management system helps maintain cost savings even when sunlight is limited.

IP65.

It can adjust power output based on real-time load data from smart meters or smart plugs (e.g., Zendure Smart Meter 3CT/D0/P1, Zendure Smart Plug, Shelly Pro 3EM, Shelly 3EM, Shelly Plus Plug S, everHome EcoTracker, everHome EcoTracker IR) and dynamic electricity pricing. This ensures efficient energy management and reduces energy waste, helping lower electricity bills

It can also charge or discharge based on fixed power settings for different times of the day, storing excess solar power during daylight hours.

Yes, it features intelligent discharge protection, keeping the battery charge above 5% (this lower discharge limit can be set by the user) and switches to AC or solar power when available to preserve battery life.

In the Zendure app, you can view real-time power generation data, historical statistics, battery charge state (SOC), charge/discharge power, and the energy consumed by the SolarFlow 800 Pro system.

It supports Wi-Fi (2.4GHz) and Bluetooth.

Yes, it is normal for the device to heat up slightly during use and will not affect performance. SolarFlow 800 Pro has overheat protection. Keep children and pets away from the device.

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.
