Question & Answer
Q&A about Zendure Solarflow
Can I install the SolarFlow 800 Pro myself?
Yes, thanks to the user-friendly plug-and-play design, installing the SolarFlow 800 Pro is straightforward and requires no special technical knowledge. So you can get your system up and running quickly and safely.
How does the SolarFlow 800 Pro help reduce electricity costs?
The SolarFlow 800 Pro combines powerful hardware with an AI-based Home Energy Management System (HEMS) to efficiently optimize energy consumption in your home. Excess solar energy is stored and intelligently used when needed, resulting in noticeable cost savings.
Powerful hardware: Equipped with a 2640W MPPT controller (4 × 660W) and a 1000W bidirectional inverter, the system enables the storage and on-demand use of solar energy – day and night.
AI-supported energy management: Through continuous analysis of generation, consumption, weather data, and electricity prices, the system dynamically adjusts charging and discharging times to, for example, make optimal use of low-tariff periods and reduce energy costs by up to 42%*.
*Based on Zendure lab tests under dynamic electricity pricing model. Actual savings may vary.
How do I choose suitable solar modules for the SolarFlow 800 Pro?
Each of the four MPPT inputs supports solar modules with up to 660 W nominal power and a maximum open circuit voltage of 55 V. For optimal performance, we recommend modules with up to 1,5 times the nominal power per MPPT to ensure maximum yield even in less than optimal weather conditions.
Is the SolarFlow 800 Pro compatible with solar modules from other manufacturers?
Yes, the SolarFlow 800 Pro supports solar modules from other brands, provided their operating voltage is between 14 V and 55 V. The maximum input voltage of 55 V must not be exceeded to avoid damage.
Can I also use less powerful modules?
Which batteries are compatible and what is the maximum capacity?
The SolarFlow 800 Pro supports Zendure batteries from the AB1000, AB2000, AB1000S, AB2000S, and AB2000X series. Multiple battery modules can be combined to achieve a total capacity of up to 11.520 Wh.
Can the battery be charged via the mains?
Yes, the system enables smart charging via the household AC grid, controlled via the Zendure app, for example, to take advantage of low-cost tariff times. When the battery level is low, it automatically switches to mains power to prevent damage.
Does the SolarFlow 800 Pro supply household appliances during a power outage?
Yes, the off-grid socket can power devices with up to 1000 W, with short-term peaks of up to 1200 W. Switching to battery operation occurs within 15 ms, ensuring an uninterrupted power supply.
Can the system operate both on-grid and off-grid at the same time?
Yes, the SolarFlow 800 Pro supports simultaneous use of grid and off-grid operation, with the maximum power in off-grid mode not exceeding 1000 W.
How does the SolarFlow 800 Pro improve energy conversion?
By using third-generation GaN (gallium nitride) technology, conversion losses are significantly reduced, increasing overall efficiency and making more solar energy available for household use.
Does the SolarFlow 800 Pro also work in bad weather?
Yes, even in cloudy or foggy conditions, the modules generate electricity, albeit with lower efficiency. Excess energy is stored or charged from the grid when tariffs are favorable, ensuring a continuous supply.
Does the SolarFlow 800 Pro have special battery management technology?
Yes, the SolarFlow 800 Pro is equipped with an intelligent battery management system that ensures effective discharge protection. The system prevents the battery level from falling below 5% – this limit can be flexibly adjusted via the Zendure app. When needed, the system automatically switches between grid power (AC) and solar power to conserve battery life and maximize battery life. This ensures safe and efficient operation around the clock.
What data can I view in the app?
The Zendure app offers comprehensive transparency and control. You get real-time insights into the SolarFlow 800 Pro's performance data, historical statistics on energy generation and usage, the current battery state of charge (SOC), charging and discharging rates, and the system's total energy consumption – all clearly displayed and accessible at any time.
Why does the SolarFlow 800 Pro start automatically when connected to the grid and cannot be turned off manually?
For safety reasons, the grid-connected inverter must continuously monitor the grid status to comply with national and international standards such as VDE-AR-N 4105 (Germany) and UL 1741 (USA). Even in standby mode, the device remains active to check the grid status at any time. Manual shutdown is not possible, as this would interrupt grid monitoring and could cause delays or malfunctions during restart. The SolarFlow 800 Pro thus ensures seamless and safe grid integration.
How does the SolarFlow 800 Pro protect itself in high temperatures?
The SolarFlow 800 Pro features an innovative "striped housing" design that ensures efficient heat dissipation. Additionally, the housing uses corrosion-resistant aluminum, which not only reduces weight but also increases heat resistance. This ensures the system remains reliable and durable even under demanding conditions.
