Generator auto start/stop on CCGX and

Venus GX

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.

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.

Wiring between the CCGX/Venus GX needs to be 'permanent' in order for the generator to keep

running; and also to allow automatic 'Stop' when the parameters for auto-stop have been met.

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 GX - Fischer Panda generators.

Enabling the start/stop function

Go to: Setttings → Relay and set the Function options to “Generator start/stop”

Relay

Now that has been enabled, all the settings pertaining to the Automatic Generator Start/Stop function

will be found in the main Menu under: Settings → Generator start and stop.

Enable the “AutoStart” function in the Fischer Panda generator control panel.1.

Go to the Fischer Panda genset page and set the Mode setting to “Auto start/stop”2.

Once the Mode is set, all settings will become available under the Auto start/stop menu entry at the

bottom of the page.

Conditions: See Conditions

Minimum runtime: Once started the generator should run for a minimum amount of time, for

manual start this setting is ignored.

Detect generator at AC input: After starting the generator, it monitors the Multi (or Quattro),

to see if it connects to the generator. In case it does not it will cause an alarm. This function

catches a wide array of possible problems, like a simple no fuel situation, but also a tripped fuse

or other problem between the generator and the Quattro. This functionality is not available for

VE.Can connected Multi/Quattro.

Quiet hours: See Quiet hours

Reset daily run time counters: Reset the last 30 days run time counters.

Generator total run time: Sets the total run time counter.

* Battery monitor: Select which battery monitor will be used for DC related conditions.

* On loss of communication: Deﬁnes the behavior when the datalink between the CCGX/Venus GX

and the selected battery monitor and/or vebus inverter/charger is lost. Options are:

Stop the generator: If the generator is running and the datalink is lost, the generator will be

stopped. (default)

Start the generator: If the datalink is lost and one or more conditions depends on it the

generator will be started.

Keep running: If the generator was already running before the datalink loss this setting will

keep it running, but will not start it if was not running previously.

* Do not run genset when AC 1 is in use: It is intended for backup systems, with a Quattro, having

mains on AC in 1, and Genset on AC in 2. When this option is enabled, the Genset will only be started

after a mains failure. And in case of a mains failure, the Genset will automatically be stopped again as

soon as the mains is restored. This functionality is not available for VE.Can connected Quattros.

The following conditions are available to auto start/stop a generator:

Manual

State of charge (SOC)

AC load*

Battery current

Battery voltage

Inverter high temperature

Inverter overload

Periodic test run

* The measured value is the system total AC consumption.

Conditions are evaluated in the order shown above and when multiple conditions are reached only the

top one will be shown as active condition. All enabled conditions are evaluated even if the generator

is already started so when the active conditions ends, the next reached condition will keep the

generator running.

Condition settings

Use “condition” value to start/stop: Enables or disables the condition

Start when “condition” is higher/lower* than: When the value set here is reached, the

relay is closed to start the generator.

Start value during quiet hours: The same that above but when the “Quiet hours” mode is

active.

Start after the condition is reached for: Some values like AC load can vary suddenly due to

Victron Energy - https://www.victronenergy.com/live/

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.

Stop when “condition” is higher than: The same than above but for stop value.

Stop value during quiet hours: The same than above but for stop value.

Stop after the condition is reached for: The same than above but for stop value.

* Higher/lower value depends on the type of condition.

AC load condition

AC load condition works like the rest of conditions but has the “Measurement” extra setting.

The “Measurement” setting is available on ﬁrmware v2.0 and onwards and has three possible values:

Total consumption (Default option)

Inverter total AC out

Inverter AC out highest phase

Test run condition

Allows you to program a periodical test run.

Test run interval: Test run will be performed periodically based on this setting

Skip test run if has been running for: The test will be skipped if during the test run interval

the generator was running at least the number of hours set on this setting.

Test interval start date: The interval count will start based on this date, this setting can be

set in the future and the interval will be ignored till the set date is reached.

Start time: Time of day in which the generator will start

Test duration: Duration of the test

Run until battery is fully charged: Stops the generator after the battery is fully charged

instead of a ﬁxed amount of time

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.

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 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.

Victron Energy - https://www.victronenergy.com/live/

WARNING: If the generator is manually started without a stop timer, won't stop until the user set to

oﬀ the manual start option.

In both options the use of a stop timer is available, use the timer to program the generator stop.

Manually stop the generator is only possible if no other condition is active. In the case that you want

to force the stop you should disable the active condition or disable the generator start and stop

function.

Quiet hours

Quiet hours allows you to set a time zone for nighttime with values that make the generator start only

when is really necessary.

When the “Quiet hours” mode is active, the conditions will use the related start/stop values.

To enable it go to the settings menu and set the “Enable quiet hours” switch on. 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" to deﬁne two time zones

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:

Solar system: A cloudy morning may cause the generator to start by a low SOC condition, then

Last update: 2018-03-21 12:57 ccgx:generator_start_stop https://www.victronenergy.com/live/ccgx:generator_start_stop?rev=1521633420

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.

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.

Troubleshooting

Fischer Panda: Generator does not start and "Remote switch control

disabled" error is shown

Enable the “AutoStart” function in the Fischer Panda control panel.

Fischer Panda: Auto start/stop function stopped working after an error

Make sure that the issue is solved and clear the error to make the auto start/stop function work again.
