 +===== Settings =====
 +
 +Before we can go into operation, we still have to setup the BMS and the inverter.
 +
 +=== JKBMS ===
 +
 +The basic setting can be easily made via the app and at first the battery type LiFePo<sub>4</sub> is selected. The other parameters should then be adjusted to the characteristics of the battery. For me, the most important parameters look like this:
 +
 +<code>
 +Balance starting voltage               3.00 V
 +Balance trigger voltage                0.01 V
 +Cell count                             16
 +Cell voltage overvoltage protection    3.60 V
 +Cell voltage overvoltage recovery      3.45 V
 +Cell voltage undervoltage protection   2.60 V
 +Cell voltage undervoltage recovery.    3.00 V
 +Max balance current                    2.00 A
 +Max charge current                     62.0 A
 +Max discharge current                  100 A
 +Power off voltage                      2.50 V
 +Total battery capacity                 310Ah
 +</code>
 +
 +=== GROWATT SPF5000ES ===
 +
 +The inverter can be set directly at the device via the control panel or via the Growatt server. I have listed the most important parameters below:
 +
 +<code>
 +Program Setting Option       Description
 +----------------------------------------------------------------------------------------------
 +1 SBU (SBU priority).   Output source priority: To configure load power source priority
 +2 62A               Maximum charging current: set total charging current for solar and utility chargers. 
 +3 APL (Appliance)       AC input voltage range
 +4 DIS (disabled)       Power saving mode enable/disable
 +5 US2 (user-defined 2)  Battery type
 +6 DIS (disabled)       Auto restart when overload occurs
 +7 DIS (disabled)       Auto restart when over temperature occurs
 +8 230V               Output voltage
 +9 50Hz               Output frequency
 +10 16               Number of series batteries connected
 +11 30A               Maximum utility charging current
 +12 48.0V (3.0V x 16).    Setting voltage point back to utility source when selecting “SBU priority” or “Solar first” in program 01
 +13 54.4V (3.4V x 16).    Setting voltage point back to battery mode when selecting “SBU priority” or “Solar first” in program 01
 +14 CSO (solar first).    Charger source priority: To configure charger source priority
 +15 ON               Alarm control
 +16 ON               Backlight control
 +17 ON               Beeps while primary source is interrupted
 +18 ENA (enabled)       Overload bypass
 +19 56.8V (3.55V x 16).   C.V. charging voltage.
 +20 54.0V (3.375V x 16)   Floating charging voltage. If self-defined is selected in program 5, this program can be set up
 +21 44.0V               Low DC cut-off voltage.
 +</code>
 +
 +
 +===== Integration in Home Assistant =====
 +
 +As mentioned above, there is a handy app for the BMS for live data and settings. It runs via Bluetooth on iOS and Android. But in order to access it via Home Assistant, we needed a Bluetooth gateway.
 +
 +:!: Warning: It must support Bluetooth 4.2 to be able to use frame lengths of more than 20 bytes. The 300 bytes of live data are sent in three notification frames.
 +
 +A simple solution can again be achieved with an ESP32 module and ESPHome. You can find the software description [[https://github.com/syssi/esphome-jk-bms|here]].
 +My setup can be found in the attachment for reference.
