- Unpack Batteries and Check Voltage
- 1. Unpack the batteries and turn each battery on by itself.
- 2. Note the voltage of each battery and serial number. The serial numbers are useful during warranty submittal.
- 3. The batteries must be within +/-0.5V of each other before commissioning. Groups of 4 batteries or more may require a narrower voltage range to commission properly.
- 4. Turn off the batteries and install them in parallel. Notes
- If the battery voltages are significantly different, one technique is to finish battery installation and only turn on the lowest voltage battery using the pushbutton. Charge the battery, and when the charging voltage is ~0.2V above the resting voltage...
- If the batteries are slightly more than +/-0.5V from each other, turning on the highest voltage batteries only will reduce their voltages, and turning on the lowest voltage batteries only will lower the highest voltage. Likewise, turning on the lowest...
- Use of the Fortress firmware update tool can help speed up commissioning times. Fortress installers should request a firmware update tool by filling out a support ticket at https://support.fortresspower.com
- Wiring Diagram
- Sunny Island(s):
- Plug the batteries into the COM Synch In port. Put the SMA canbus terminator into the COM Sync Out port on the last inverter in the communication chain. eFlex 5.4kWh LFP
- eVault Max 18.5kWh LFP
- eVaultMAX Battery Touchscreen
- Inverter Settings
Number each battery 1,2,3,4,5.... until the end of the battery circuit.
Except, if only installing one eVault MAX, number the battery "0".
Protocol ID
1 = Sol-Ark / Any inverter
2 = SMA
3 = Reserved
4 - Victron
5 = Schneider
Inverter Settings
The settings that are to be used to program the SMA inverter are provided in
the table below (Table 1). For detailed information on how to commission the SMA
inverter and navigate through its settings menu, follow the URL
link, https://www.youtube.com/watch?v=n0cYWfk8wXQ, which takes one to the
SMA's tutorial video for SMA 6048-US.
Note: Please make sure to update Sunny Island Firmware to version 7.3.04 or
better
SMA Settings for Closed Loop Operation
All unspecified settings will remain at factory values
Password for SMAe inverter is the Sum of AH in the Password Menu
Ex. 105 Ah Total = 1 + 0 + 5 = 6
