+====== Victron & Exide =====
+**This combination depends on Venus OS v2.90 or above, which is scheduled to be released later in 2022. Or the latest beta (see [[ccgx:beta-testing|]]).**
 The combination of Victron products with the Exide battery has been tested and certified by the R&D departments. The combination is actively supported by both companies.
 Compatible models:
-  * LIBM0480050-G01 as of firmware v1.10
+  * Sonnenschein Module Pro LIBM0480050-G01 as of firmware v1.10

 ==== 1. Introduction ====

 === 1.1 Compatible Victron products ===
 All 48V Multis and Quattros. And always a [[venus-os:start|GX device]] is necessary in the system, since that has the canbus port which is used for the (required!) communication between the ESS battery and the Victron system.
-=== 1.2 Notes ===
-=== 1.3 System diagram ===
 ==== 2. GX device needed ====
-To use the Exide ESS in Victron system, it is necessary to use a Color Control GX or Venus GX. On first commissioning an external power supply (Not the 48V from the Exide-Battery) is needed. The GX device sends a keep alive signal to the Exide ESS via canbus. This will only be send once the canbus baud rate is changed (see 5. [[venus-os:start|GX device]] Configuration). Without it, the battery will have a communication fault and shut down after 10sec.
+To use the Exide ESS in Victron system, it is necessary to use a GX-device such as a Color Control GX, a Venus GX or a Cerbo GX. The GX device needs to run at least firmware v2.90. It is recommended to always use the latest Firmware version for the GX device.
 ==== 3. Wiring of communication cables ====
-Use the //VE.Can to CAN-bus BMS type B Cable//, part number ASS030720018. Plug the side which is labeled Battery BMS into the Exide BMS. Plug the side labeled Victron VE.Can into the [[venus-os:start|GX device]].
+A cable for the CAN-bus connection ships with the battery. This cable has only CAN-L and CAN-H connections and no ground wire. The side of the cable with pins 7 and 8 should be plugged into the
+[[venus-os:start|GX device]], and the side with pins 1 (CAN-L) and 2 (CAN-H) goes to the battery.
-Then, plug a [[https://www.victronenergy.com/accessories/ve-can-rj45-terminator|VE.Can terminator]] in the other VE.Can socket on the [[venus-os:start|GX device]]. Two VE.Can terminators are included with the package of the GX device as an accessory, only one is used. Keep the other one as a spare.
+Exide batteries come with a CAN-bus terminator already installed/supplied. When assembling the battery from individual modules, remember to terminate the CAN-bus on the last module, using the supplied terminator. In most cases, this is already done in the factory.
-More information about the cable can be found in [[battery_compatibility:can-bus_bms-cable|its manual]].
 Without properly connecting this cable, the battery will stop charging/discharging after several minutes. Also, the battery will not show up on the display of the [[venus-os:start|GX device]].
 ==== 4. VEConfigure settings ====
+=== 4.1 General tab ===
+  * Check the "Enable battery monitor" function
+  * Set the battery capacity to the total capacity of the battery: the Ah capacity per module multiplied by the number of battery modules.
+  * The other parameters ("State of charge when bulk finished" and "Charge efficiency") can be left to their default setting: They have no effect in this type of installation.
+=== 4.2 Charge Settings ===
+=== Charger tab ===
+^ Parameter              ^ Setting ^
+| Battery type           | Lithium |
+| Charge curve           | Fixed   |
+| Absorption voltage     | 51.0 V  |
+| Float voltage          | 50.8 V  |
+| Absorption time        | 1 Hr    |
+Note: make sure to double check the float voltage after completing Assistants, and if necessary set it back to 50.8 V.
+=== 4.3 Inverter Settings ===
+In the Inverter tab of VEConfigure
+^VEConfigure Inverter Parameter              ^Setting^
+|DC input low shut-down | 42V|
+|DC input low restart   | 45V|
+|DC input low pre-alarm* | 45V|
+* The pre-alarm setting is dependent on your preference and on site specific requirements. You may wish for this to be activated earlier in an off grid situation to allow time to start a backup generator.
+=== 4.4 ESS System Settings ===
+If you are using the battery as part of a [[ess:start|grid connected ESS system]], please review the [[ess:quick-installation-guide|ESS Quickstart guide]] and [[ess:design-installation-manual|Design and Installation Manual]].
+The settings that are specific to the EXIDE battery in the VEConfigure ESS Assistant are below:
+Select the externally managed Lithium battery option
+{{:battery_compatibility:ess-battery-system-selection.png?nolink|}}
+^ ESS Parameter ^ Settings ^
+|Sustain voltage.       | 45V|
+|Dynamic cut-off values | set all values to 43.5V.|
+|Restart offset:        |1.2V (Default)|
+Due to the reliability of the grid supply and the behaviour of the sustain voltage threshold in ESS; you may wish to suppress the low voltage pre-alarm warning so that it does not trigger every day on its regular deep cycle. See [[https://www.victronenergy.com/live/ess:design-installation-manual#faq|ESS FAQ Q5]] - about suppressing the low-voltage alarm.
