-====== Generator auto start/stop on CCGX and Venus GX ======
+====== GX - Generator auto start/stop ======
-===== Introduction =====
+===== 1. Introduction =====
-An internal relay on the CCGX/Venus GX can be used to automatically start and stop a generator. This relay - or switch - can be 'tripped' by a number of user-defined conditions. This manual will explain what conditions are available to you; and it will guide you through the steps required to set-up this useful functionality.
+An internal relay on a [[venus-os:start|GX device]] (eg [[https://www.victronenergy.com/panel-systems-remote-monitoring/color-control|CCGX]]/[[https://www.victronenergy.com/panel-systems-remote-monitoring/venus-gx|Venus GX]]) can be used to automatically start and stop a generator. This relay - or switch - can be 'tripped' by a number of user-defined conditions. This manual will explain what conditions are available to you; and it will guide you through the steps required to set-up this useful functionality.
+This is one of the available options to automatically start and stop a generator. See the [[auto-generator-start-stop:start|]] document for an overview of all options. More general information about  using a generator in combination with Victron is available [[:multiplus_faq|here]].
+===== 2. Wiring =====
 Firstly, wire the relay to a genset. The relay is located on the back of the CCGX - marked //Relay//. If using a Venus GX, two relays will be seen at the bottom of the unit - only //Relay 1// can be used for the generator automatic start/stop functionality.

 Besides driving the internal relay, the auto start/stop functionality can be also enabled to directly control supported Fischer Panda generators. For more information on how to connect Fischer Panda generators, see [[ccgx:fischer_panda|]].
-===== Enabling the start/stop function =====
+There are many variations on the generator side for wiring and you should also consult your generator manual or supplier regarding their remote wire start configuration.

-==== Relays triggered by Battery Voltage ====
+=== Relays triggered by Battery SOC ===
+  ***Use Battery SOC value to start/stop:** Toggle this feature on or off.
+  ***Start when Battery SOC is lower than:** Set the depletion level for auto-start.
+  ***Start value during quiet hours:** During [[#Quiet hours|Quiet hours]] it may be desirable to delay an auto-start until it really can't be avoided. If //Quiet hours// has been defined, set a lower, more critical, autostart level.
+  ***Stop when Battery SOC is higher than:** Set the recharge level for auto-stop.
+  ***Stop value during quiet hours:** If [[#Quiet hours|Quiet hours]] has been defined, set a lower auto-stop level to achieve a shorter generator run-time.
+=== Relays triggered by Battery Current ===
+  ***Use Battery current value to start/stop:** Toggle this feature on or off.
+  ***Start when Battery current is higher than:** When a high AC demand is experienced which will soon exhaust the battery, the generator can be auto-started to assist in meeting that demand. Set the current-level at which this will occur.
+  ***Start value during quiet hours:** If [[#Quiet hours|Quiet hours]] has been defined, set a higher, more critical current value.
+  ***Start after condition is reached for:** Set a delay before auto-start. Some AC device will draw a short-term, high-peak current on start-up. Instigating a delay before auto-start will avoid starting the generator unnecessarily.
+  ***Stop when battery current is lower than:** Set the current for auto-stop.

+  * **Start value during quiet hours**: If [[#Quiet_hours|Quiet hours]] has been defined enter a lower (more critical) value to ensure the generator will only auto-start when absolutely necessary.
-  * ** Start after the condition is reached for**: Some values like AC load can vary suddenly due to a consumption peak and go back to a normal value in a few seconds. In this kind of situations the start of the generator is usually not desired. This option will delay the generator start until the start value is reached for a minimum amount time.
+  * ** Start after the condition is reached for**: This function allows the user to build-in a delay between the auto-start condition being met and an auto-start being triggered. The importance of this is that a sudden but temporary high AC demand will cause an equally sudden drop in battery voltage. This drop //may// be temporary - in which case a generator start is not required. But if the condition endures for a longer period of time than the value entered here, the generator will be started.
-  * **Stop when "condition" is higher than**: The same than above but for stop value.
+  * **Stop when battery voltage is higher than**:  When battery voltage rises above the value entered the relay will stop the generator.
-  * **Stop value during quiet hours**: The same than above but for stop value.
+  * **Stop value during quiet hours**: During [[#Quiet hours|Quiet hours]] it may be desirable to auto-stop the generator sooner. Enter a lower battery voltage value than the one above.
-  * ** Stop after the condition is reached for**: The same than above but for stop value.
+  * ** Stop after the condition is reached for**: This feature builds in a delay before stopping the generator after the 'stop' value has been reached. This is to make sure that the voltage rise is stable.
-* Higher/lower value depends on the type of condition.

-  * **Inverter AC out highest phase**
+=== Relays triggered by Inverter High temperature ===
+  ***Start on high temperature warning:** Toggle this feature on or off.
+  ***Start when warning is active for:** Set a delay to avoid temperature rises which are temporary, caused by brief high AC demands.
+  ***When warning is cleared stop after:** Set a delay to ensure that a reduction in inverter temperature - usually caused by lower power demand - is stable.
+=== Relays triggered by Inverter overload ===
+  ***Start on overload warning:** Toggle this feature on or off.
+  ***Start when warning is active for:** Set a delay to ensure that the inverter overload warning has not been triggered by a high-demand of AC power of only short duration.
+  ***When warning is cleared stop after:** Set a delay to ensure that the reduction in AC power demand is stable.

-==== Manual start ===
-Use the manual start to directly start the generator. If the generator is already running you can use this option to make sure that the generator won't stop automatically when the active condition becomes inactive.
+=== Manual-Start Feature ===
+Use the //Manual start// feature to remotely start the generator. You can also press Start when the generator is already running - doing so will ensure that the generator won't automatically stop when the condition which caused it to start has been satisfied. In other words, the //Manual start// feature will override the auto-stop parameters.
 There are two ways to start the generator manually:
-  * **Using menu**: Go to Generator start and stop -> Manual start and use the switch to start the generator.
+  * **Using the Manual start menu**: Go to: Generator start and stop -> Manual start; and then toggle the graphic to start the generator.
-  * **Using generator page**: Press the top-left button to show the generator page. Once in the generator page press the center button, when pressed you will be asked how to stop the generator, manually or using a timer. Once selected the stop mode a countdown of five seconds will start, you can abort the manual start by pressing the center button.
+  * **Using the GX 'Home page' Generator graphic**: Press the top-left button on the CCGX, or Venus GX remote console and engage the //Generator// page. Then press the center button. You must first choose how you wish to //stop// the generator - manually, or by entering a run-time. Once you've made your selection a five-second countdown will begin during which you can //abort//  the manual-start by pressing the center button.

-===== Quiet hours =====
+=== Quiet hours ===
 {{:ccgx:startstop-quiethours.png?300|}}
-Quiet hours allows you to set a time zone for nighttime with values that make the generator start only when is really necessary.
+//Quiet hours// allows you to define a period during which the noise from a running generator would be a nuisance; and to set different values to the conditions which would cause an auto-start during this period - thus ensuring that the generator will only start during a quiet period when it is absolutely necessary.
-When the "Quiet hours" mode is active, the conditions will use the related start/stop values.
+From the main menu go to: Settings -> Generator start/stop -> Settings; and then
+toggle-on the //Quiet hours// feature. Define the //Quiet hours// start- and end- times in the boxes which appear below.
-To enable it go to the settings menu and set the "Enable quiet hours" switch on.
+//Quiet hours// will become the permanent condition (when enabled) if the defined 'start' and 'stop' times are the same.
-Once enabled start and end time settings will become visible.
-You can make the "Quiet hours" mode to be permanently active(when enabled) setting both start and stop time to the same value.
+=== Using "Quiet hours" as a tool to define two sets of user-preferences ===
+Alternatively, the "Quiet hours" feature can be used to define how you wish your system to respond to different circumstances - for example:
-=== Using "Quiet hours" to define two time zones ===
+  * **Early morning/low SOC**: Battery SOC is often lowest in the morning. Couple this with cloudy weather first thing - or panels which have a westerly bias, and which tend to do better in the afternoon; and you have a circumstance where the generator may auto-start in the morning triggered by a low battery SOC condition - yet later on when the day brightens the solar energy is wasted because the work has already been done by the generator. Setting the //Quiet hours// feature to cover this period, together with lower auto-start conditions, will help to avoid unnecessary generator auto-starts.
-Besides the main purpose of the "Quiet hours" mode you can also use it to define two time zones over the day.
-Examples of the use of different time zones:
+  * **Holiday home**: Holiday homes which are only inhabited part-time experience much deeper power-draws when they are in use. The //Quiet hours// feature can be used to set much lower auto-start parameters when the house is in use, than when it is empty. Quiet hours should be set to be the //permanent condition// (See above) during occupation; and the //Quiet hours// feature can be toggled 'off' whenever the house is empty.
+===== 7. Troubleshooting =====
+=== Fischer Panda: Generator does not start and "Remote switch control disabled" error is shown ===
-  * **Solar system**: A cloudy morning may cause the generator to start by a low SOC condition, then two hours after the clouds go away. In this case your batteries are charged and your solar system wasting free energy. To avoid this situation you can set a time zone for daytime with a lower start value for the SOC condition.
+Enable the "AutoStart" function in the Fischer Panda control panel.
-  * **Away mode**: Some holiday houses are only inhabited on weekends during which power consumption is larger and the generator has to take care of keep batteries in good condfition. The rest of the week the battery SOC level can be lower waiting to be charged by solar energy. With time zones you can set a secondary time zone for the whole day and only enable/disable it when the house is uninhabited.
