ESS (Energy Storage System) (size:978)
*) System uses LiFePo4 with other type BMS
(This can be either a BMS connected via CAN bus or a BMS system in which the
batteries are protected from high/low cell voltages by external equipment.)
*) The battery capacity of the system is 200 Ah.
*) Sustain voltage 48.00 V.
*) Cut off voltage for a discharge current of:
0.005 C= 46.00 V
0.25 C= 46.00 V
0.7 C= 46.00 V
2 C= 46.00 V
*) Inverting is allowed again when voltage rises 1.20 V above cut-off(0).
*) Relevant VEConfigure settings:
- Battery capacity 200 Ah.
- PowerAssist unchecked
- Lithium batteries checked
- Dynamic current limiter unchecked
- Storage mode unchecked
Total size of all assistants including the required
(hidden) system assistants is: 1037

h3. ESPhome *ESPhome grid meter
meter*
Using the the following extra software on the GX device to enable mqtt devices to connect to the victron GX and be used as a grid meter:
https://github.com/freakent/dbus-mqtt-devices
Using the following ESPHome alternate P1 meter configuration to send P1 data to the GX device AND to home assistant:
after updating the firmware you seem to need to run the setup.sh script again.
[[esphome p1meter victron version]]
h3. GX *GX to Home Assistant Assistant*
To get information from the GX device into home assistant you can use the following HACS addon: https://github.com/sfstar/hass-victron
To get the battery input/output into the energy dashboard you need to split the sensor.victron_system_battery_power into two values with template sensors and add two cummulative entries with the integration platform.

h3. GX *GX Venus OS Large Large*
You can update the firmware with a Venus OS Large version. This version includes Node-RED. In the Remote Console, this can be enabled and you can finde node-red on https://venus:1881/
when installing Venus OS Large, you better run
/opt/victronenergy/swupdate-scripts/resize2fs.sh
