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.

Each MPPT input supports a maximum power of 600W, 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 batteries. You can mix AB1000 and AB2000 series batteries, with up to 6 stacked units, for a total capacity of up to 11,520Wh.

Yes, the SolarFlow 800 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.

Rainy or foggy days cut solar power, and solar panels still work at reduced efficiency. With batteries, store extra solar energy or charge cheaply during low-rate hours for uninterrupted power. This smart energy management maintains cost savings even when sunlight is scarce.

IP67. SolarFlow 800 provides a higher level of protection than products with only "water-resistant" IP65 or IP66 ratings.

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

2.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 system.

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

No, according to EU safety regulations, the SolarFlow 800 will stop supplying power during a power outage and cannot be used as a backup power system.

Yes, it is normal for the device to heat up slightly during use and will not affect performance. SolarFlow 800 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.

No, SolarFlow 800 is not compatible with Ace 1500. It's not recommended to do that for a better experience.

No.
