Unpack Batteries + 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 of the next lowest battery, turn it on too. Proceed until all batteries are

turned on and at the same voltage level. If the batteries are below 51V, keep

charging amperages below 10A per battery.

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

voltage batteries as a group will raise the lowest voltage. Then, all the batteries can

be turned on within a 0.5/V difference.

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

Schneider Monitoring w/Fortress

Schneider has an online monitoring system called the Insight Local and the Insight Cloud.

Two steps are needed to share your system with Fortress:

1) Register the site to the Insight cloud and then share the plant including full admin/manager

permissions with techsupport@fortresspower.com.

While batteries are off. Install the battery-battery communication cables.

Note: TheRJ45 pin-out converter is not a simple female-female RJ45 connector! It includes a terminating resistor similar to the other end of the battery communication circuit, but also passes through the inverter communication. Running on 1 eFlex Running any Schneider Inverter with 1 eFlex is not compliant with Fortress minimum sizing standards.

3. Install a ethernet cable into one end of the battery communication circuit to land on the RJ45 pinout converter. The cable on the other side of the RJ45 pinout converter will need to be cut and modified before connecting to the Schneider Insight Home/Gateway. If not using a battery-inverter communication circuit, install an IP65 Bus Terminator instead. 4. User will need an extra LAN Ethernet cable to make connection. Cut and strip the green, brown-white, and brown cables.

Battery- Battery Connection The eVault MAX uses canbus to communicate from battery to battery. This occurs over the COM_Parallel ports. The ports are bidirectional. Canbus communication requires resistor termination to function without blips. Fortunately, the eVault MAX has internal canbus resistors! Terminate these resistors by using the dipswitches in the upper service cabinet within the battery. The dip switches should be in the ON position for the batteries at the end of the communication circuit.

Turn the terminator switch to 120ohms and place the communication cable into the RS485 port. Finally switch to protocol 5. 1. When paralleling multiple batteries, choose which battery will be the master 2. 3. 4. 5. and which will be the slave. You can do this by Setting the Master battery ID to 1 and set the rest in chronological order.

After the battery unsticks, power down and then power back up the battery banks using the push button if convenient.

Follow these steps to successfully integrate the battery’s BMS to the XW PRO. Note: You can integrate the battery's BMS with other Schneider Models using a Gateway or an Insight Home/Facility but will not achieve Closed Loop. Note: Choose a 19200 BAUD Rate for the eVault Max. Otherwise use a 9600 BAUD Rate for the eFlex and the eVault Classic.

Important Note Please Note, that these are recommended parameters for specific Mode Settings. Modes such as Off Grid and Back up require other additional modification aside from this document. Please reference XW Pro Commissioning Guide - Schneider Electric Solar (schneider-electric.com) under Select System type. Make sure that you program the correct Region Settings on your inverter. Finally state the correct Time Zone settings under the Setup section.

Generator Settings Generator Settings (Applicable to all Mode Settings) 20% state of charge is approximately 51.2V-51.4V. 95% charge is approximately 53.7V. A 100% charge 54.4V. NOTE: Voltages are assuming an open circuit resting measurement. The settings that would discharge the battery down to 49V, are too low for Fortress batteries. Fortress batteries should only be intentionally discharged down to 20% SoC or 51.4V and then be recharged by available charging sources.

Firmware updates are rarely needed. Most firmware updates solve a minor issue - major firmware updates typically are adding compatibility with new-to-market hardware or to accommodate developments in battery-inverter communication. Most of our installers use the firmware update tool to confirm proper system commissioning or unlock batteries from their protective modes during a deep discharge. To update the battery firmware, please visit https://www.fortresspower.com/firmware.
