Alpha Outback SPC Monitoring
You can monitor and configure your inverter locally using the WatchPower software supplied on the inverter CD. For this you need an RS-232 port on the PC and the RS-232 adapter cable. Please note that none of the SPC's RJ45 ports are intended for Ethernet connections. If required, you can monitor the inverter locally using a USB-to-RS232 adapter. For internet-based monitoring of the SPC, you can use the WiFi Box, GPRS Box or SNMP Box.

BYD | BCU Not Responding | LED Does Not Light Up
The LEDs do not light even though the circuit breaker is latched.
Check the number of modules Make sure the minimum number of modules is installed: HVS requires at least 2 modules and HVM at least 3 modules.
Voltage measurement Remove the BCU and measure the tower voltage at the top module.
Note: The nominal tower voltage should be approximately the number of modules multiplied by 100 V for HVS or by 50 V for HVM. Examples: 3 HVS modules ≈ 300 V; 5 HVM modules ≈ 250 V.
Correct startup sequence Important: Switch on the battery first and only then the inverter. Otherwise the BCU may not respond, with no LED and no Wi-Fi.
Switch off the battery by holding the power button for 5 seconds.
Switch off the inverter DC switch.
Switch off the inverter AC circuit breaker.
Kostal only: disconnect the PV strings from the inverter.
Remove the BCU from the tower and reinstall it after 5 minutes. Keep the inverter switched off during this time.
Switch on the battery by moving the breaker lever up. The LED should light.
Kostal only: reconnect the PV strings.
Switch on the inverter AC circuit breaker.
Switch on the inverter DC switch.
Only the LED is off? Check whether the Battery-Box Wi-Fi access point is available. If Wi-Fi is present, only the LED itself may be inactive and commissioning can still be possible. In this case, check that the internal LED cable is connected correctly.

BYD | BCU Circuit Breaker Will Not Latch | LED Stays On
The circuit-breaker lever does not latch, immediately drops again, or the LED remains on even though the lever is down.
Close the cover Close the BCU connection-area cover correctly. Important: For safety reasons the battery cannot be switched on while the connection area is open.
The circuit breaker was pulled down manually If the switch was pulled down/switched off manually, it cannot be pushed back up and reactivated for approximately 10 minutes. Refer to the instructions for the correct shutdown procedure.
Continuously blue LED / EC 102? EC 102 is indicated by 1x white and 2x blue flashes. Try to shut down the BCU correctly by holding the button for 5 seconds.
If the LED goes out: check the DC wiring, make sure the battery configuration in the app/BCP was completed correctly, including module type and number, and restart the system in the correct sequence.
If the LED remains on continuously blue or flashing EC 102: remove the BCU from the tower to prevent deep discharge, measure the voltage and contact a service partner.

BYD | Firmware Update Problems | App Configuration | Wi-Fi
The BCU consists of two components: the BMU and the BMS. A firmware update from the app first updates the BMU, which then updates the BMS. The BMS update starts only when communication between the battery and inverter is established or directly after app configuration. It can take up to approximately 20 minutes for the BMS firmware to update.
Correct app and firmware Make sure the latest app version and latest Battery-Box firmware are available on the mobile device before connecting the app to the battery Wi-Fi. If the app cannot be installed or other general app problems occur:
Try a different mobile device.
Uninstall and reinstall the app.
Alternatively use the Be Connect Plus (BCP) PC tool.
Wi-Fi not found / Wi-Fi unstable The battery Wi-Fi switches off approximately 5 hours after battery startup. To reactivate it, press the LED button for about 1 second or restart the system. To reset the Wi-Fi, press the LED button three times for about 1 second each within 6 seconds.
If the problem continues:
Remove the LAN cable during configuration. Reconnect the BCU to the internet only after the battery has been configured correctly.
Check whether other mobile devices are connected to the same Wi-Fi.
Try a different mobile device.
BMS version does not update The app updates the BMU; the BMU then updates the BMS. Once the BMU is updated and inverter communication is stable, or directly after configuration is completed, the BMS update can take around 20 minutes. If the BMS version has still not updated after 20 minutes with stable inverter communication:
Update the firmware again through the app.
Restart the system:
Switch off the inverter first and then the battery by holding the LED button for 5 seconds.
Wait 30 seconds.
Switch on the battery first and then the inverter.
Wait 20 minutes.
Check the BMS firmware version again in the app. If the version is still incorrect, repeat the update process, if possible using a different mobile device.

Initial SOC on commissioning New HVS/HVM modules always have a state of charge of approx. 30% on delivery. However, when commissioning a new storage system, the BCU usually displays an incorrect state of charge at the beginning (usually 50%/30%/0%). However, this is only to be understood as a placeholder value. During a new installation, the BCU simply does not yet know what the charge status of the modules is. As soon as the memory starts to charge, the SOC detection is corrected step by step. The SOC calibration is completed at the latest after a full cycle (charge to 100% and subsequent discharge to max. discharge depth).
SOC jumps The state of charge of an LFP battery cannot be measured. It is a calculated value. In general, the state of charge of a battery is calculated via the voltage, but other factors such as temperature, current flow and charging behavior also play a role. The calculation of the state of charge is generally more accurate if the battery regularly sees full cycles. Again & in very clear terms: The SOC is only calculated approximately and can deviate from the real value by several percentage points. Corrections occur from time to time. This is normal.

This manual is suitable for both hybrid and string inverters. See page 7 for battery inverters.
Once this has been completed successfully, review VictronConnect and the Remote Console, including all settings. Detailed instructions and explanations are available for each item.
You should also update the firmware on all devices, excluding beta versions, and then configure the VEConfigure file. In VictronConnect, this can be found under Devices.
If these buttons are not visible, enable two-way communication in the Remote Console.
Next, configure the settings in VEConfigure. This includes loading the ESS Assistant and, for Pylontech batteries, applying the settings provided here:
If the information supplied by inutec and the manufacturer is insufficient, you can also book a paid one-hour setup session for €75 net.

How do I find the right Victron MPPT charge controller for my modules?

How do I find the right Victron MPPT charge controller for my modules?
To design and select a Victron charge controller, it is best to use the Victron tool MPPT charge controller calculation, which you can download here:
You can create your selected modulethere by entering the current and voltage data of your module there and creating everything under the name of your module. Now you can see, for example, whether you can place more than 8 modules per string on the MPPT 450/100 Tr.
In terms of power, this MPPT can process around 6 kWp (5.8 kW max. charging power). Now you would have to divide the modules accordingly.
