+==== **6.** **BlueNova Energy battery setup with DVCC enabled**
+       (DVCC - Distributed Voltage and Current Control) ====
+Introduction and features
+Enabling DVCC in a setup containing a BlueNova Energy battery,  changes the GX device from a passive monitor into an active controller.
+The GX device  receives the Charge Voltage Limit (CVL), Charge Current Limit (CCL), Discharge Current Limit (DCL) as  well  as  the  Battery  Low  Voltage   from the battery and relays that to the connected inverter/chargers and solar chargers. These then disable their internal charge algorithms and simply do what they're told by the battery. There is no need to set-up charge voltages or choose the charge algorithm type.

+Shared Voltage Sense (SVS)
+Works with VE.Bus devices and VE.Direct Solar Chargers.
+The system automatically selects the best available voltage measurement. It will use the voltage from the BlueNova Energy  battery  BMS or a BMV battery monitor, if possible, otherwise it will use the battery voltage reported by the VE.Bus system.
+The voltage displayed on the GUI reﬂects the same voltage measurement.
+**Shared Voltage Sense** (SVS) is by default enabled when DVCC is enabled. It can be disabled with a switch in the Settings → System Setup menu.
+**Limit charge current**  -
+This is a user-conﬁgurable maximum charge current setting and can, in majority of cases, be   disabled for BlueNova Energy batteries.  It works across the whole system. MPPT Solar Chargers are automatically prioritized over the mains/generator.
+To enable or disable DVCC, see Settings → System Setup in the menus.
+**DVCC Requirements :**
+Battery compatilibity  -
+DVCC has extensively been tested on BlueNova Energy batteries and is therefore fully supported .
+**Firmware versions :**
+Do not use DVCC in cases where these requirements(Victron) are not met. In all cases we recommend to install the latest available ﬁrmware during commissioning. Once running well, there is no need to pro- actively update ﬁrmware without reason. In case of diﬃculty, the ﬁrst action is to update ﬁrmware.
+**Required minimum ﬁrmware versions:**
+BlueNova Energy  123SmartBMS : v5.12
+BlueNova Energy BMMC : V3.5
+Multi/Quattro: 422
+MultiGrid: 424
+CCGX / Venus GX: v2.12 VE.Direct MPPTs: v1.29
+VE.Can MPPT Solar Chargers cannot be used: they do not yet support the new control mechanisms.
+Lynx Ion + Shunt: v2.04 Lynx BMS: v1.09
+In case of an ESS System, the ESS Assistant needs to be version 164 or later (Released in November 2017).
+==== 7. Configure MPPT ====
