• When sunlight is sufficient, photovoltaic power is used to supply power to the household according to the set power, and the excess power is charged and stored in the battery. When the battery is fully charged or is not charging due to low temperature, photovoltaic power will be fully output through the microinverter to supply power to the household.
• When sunlight is insufficient, if the conditions for switching photovoltaic discharge to battery discharge are met, the photovoltaic power supply will be switched to the battery power supply, and the battery will power the household according to the set power. If the conditions are not met, the photovoltaic power supply continues. In this condition, the output power of the microinverter may not meet the household power demand. There are two conditions for switching the photovoltaic power supply to the battery power supply: The first condition is that, when the photovoltaic input power is less than 20 W (with a duration of more than 10 minutes), or when the photovoltaic input power is less than 100 W and the set "Family Load" power is 100 W greater than the actual photovoltaic input power (with a duration of more than 10 minutes), the switchover occurs.
• The other condition is that, when sunlight is insufficient and photovoltaic panels are not generating electricity, the battery will power the household according to the desired power.

• If the power consumption demand at noon is 100 W and the generated photovoltaic power is 600 W, since the generated photovoltaic power (600 W) is much greater than the power consumption demand (100 W), Solarbank E1600 will simultaneously supply 100 W of power to the household through the microinverter and store 500 W in the battery.
• If the power consumption demand in the evening is 600 W and the generated photovoltaic power is 50 W, since the generated photovoltaic power (50 W) is far less than the power consumption demand (600 W), the battery will supply 600 W of power to the household.
• If the power consumption demand in the evening is 600 W and the generated photovoltaic power is 10 W, since the generated photovoltaic power is less than 20 W, the battery will supply 600 W of power to the household.
• If the power consumption demand in the morning is 150 W and the generated photovoltaic power is 80 W, in order to make better use of the generated photovoltaic power, Solarbank E1600 outputs 80 W through the microinverter to the grid, and the battery does not supply any power.

• When the Solarbank E1600 battery is being charged: the microinverter operates stably at the maximum power before it starts to adjust the charging power of the battery. Therefore, during the startup process of the microinverter, the output power will transiently exceed the power set in the "Family Load Setting".
• When the Solarbank E1600 battery is almost full: in order to protect the battery, it is charged at a low power. In this situation, the charging power decreases and the output power of the microinverter increases and exceeds the power set in the "Family Load Setting".

• When the light intensity changes and the output power of the microinverter approaches the lower limit for stable microinverter operation (about 150 W), the output becomes unstable.
• When the light intensity is stable and the set power in the "Family Load Setting" approaches the lower limit for stable microinverter operation, the output becomes unstable (note that the minimum power for the stable operation of certain third-party microinverters is much greater than 150 W, such as for Deye microinverters.)

• Before the microinverter is successfully started, the battery is charged at a power of about 35 W to reserve sufficient power for the microinverter to be started. After the microinverter operates stably, the charging power of the battery will increase. (Some third-party microinverters take up to 7 minutes to start up, and therefore please wait patiently for the startup to complete.)
• If you are using the MI80 microinverter, the battery will be charged at a power of about 35 W when the MI80 microinverter fails to start. In this situation, please check that the Wi-Fi connection status of Solarbank E1600 or the MI80 microinverter is normal.
• When a municipal power outage occurs or the AC cable of the microinverter is disconnected.

• The version of the app or Solarbank E1600 is relatively old: If this is the case, upgrade the app to the latest version, and then upgrade the Solarbank firmware to the latest version.
• The photovoltaic panel is operating improperly: Only connect Solarbank E1600 to the photovoltaic panel and not to the microinverter. Then, press and hold both buttons on Solarbank E1600 for 15 seconds to restart it until the indicator flashes.

• The photovoltaic input remains less than 20 W for more than 10 minutes.
• The photovoltaic input power remains less than 100 W and the power set in the "Family Load Setting" remains 100-W higher than the actual photovoltaic input power for more than 10 minutes.

• Check that the router is communicating with Solarbank E1600 at 2.4 GHz, because Solarbank E1600 does not support Wi-Fi communications at 5 GHz.
• Relocate the device to a position that is within 10 meters of the router. Also, ensure that few obstacles and walls (if possible) exist between them to ensure that there is a strong Wi-Fi signal. Alternatively, add more repeaters to enhance the signal.
• Check whether the number of devices connected to the Wi-Fi network has reached the upper limit. If it has, disconnect some devices.
• Check whether the "IOT Status LED" is flashing green. When it flashes green, the connection is being reestablished. In this situation, you can use your cell phone to establish a Bluetooth connection with Solarbank E1600, and then reconfigure the Wi-Fi connection.
• Upgrade both the app and firmware to their latest versions.

• The conditions for the photovoltaic panel to swap to battery discharge are as follows:
• The household load has a demand for power, and the power set in the "Family Load Setting" is not 0 W in the Anker app.
• The light intensity is high, and the system has determined that the battery can be charged, but the battery is already fully charged; or, the temperature is around 0 °C and the battery cannot be charged.
• The light intensity is low, but the photovoltaic panel and battery cannot supply power at the same time, and the conditions for the photovoltaic panel to swap to battery discharge have not been met. As a result, the battery does not discharge, and the system displays Standby.
• No light is available, and the power in the "Family Load Setting" is set to 0 W. Therefore, the battery does not discharge and the system displays Standby.

• The photovoltaic input remains less than 20 W for more than 10 minutes.
• The photovoltaic input power remains less than 100 W and the power set in the "Family Load Setting" remains 100-W higher than the actual photovoltaic input power for more than 10 minutes.

• You can only set the total output power of the two Solarbank E1600 units to 0 W, but cannot set one of them to 0 W and not set the other to 0 W.
• When the total output power is not 0 W, by default, both Solarbank E1600 units distribute the power equally according to the set power. You can also set the output power of each Solarbank E1600 unit in "Advanced settings" as needed, and their output power values can be different.
• When the Wi-Fi connections between both Solarbank E1600 units and the MI80 microinverter are normal, if one of the units has reached the minimum power and cannot supply power, the other unit will continue to supply power to the household.

1. If the indicator flashes red, wait for 30 seconds to see whether the fault will be corrected automatically. If it is corrected, then no further action is required.
2. If it is not corrected, then press the power button once to manually correct the fault.
3. If this does not correct the fault, remove the input and output cables of Solarbank E1600 and turn it off and then on again. Next, troubleshoot based on the following possible conditions:

• If the indicator still flashes red after the restart, the fault may stem from Solarbank E1600.
• If the indicator no longer flashes red after the restart, the fault may stem from the photovoltaic panels or the microinverter. To determine the exact cause, connect Solarbank E1600 to only the microinverter or only the photovoltaic panels, and check if the indicator still flashes red to identify whether the fault is coming from the photovoltaic panels or the microinverter.

• If the Bluetooth connection between the 0W switch and Solarbank E1600 is normal initially but disconnected later, the indicator of the 0W switch flashes white once, indicating that it is waiting for Bluetooth connection to be repaired. In this condition, the state of the 0W switch is grayed out (offline) on the Solarbank page of the Anker app.
• When there is no sunlight, the "Family Load Setting" is set to 0. In this condition, the 0W switch is not powered and its indicator is off. On the Solarbank page of the Anker app, the 0W switch is grayed out (offline), which is normal.

• Tap "Device" > "MI80 Microinverter".
• Tap the Setting icon in the upper right corner.
• Check the "Maximum Output Power". If the value is 800 W, it means that the maximum output power of MI80 has been upgraded to 800 W. If the value remains 600 W, please provide us with your "SN", and we will upgrade MI80 for you.
