 +==== 1. Which relay and control to use? ====
  
 Various Victron products have functions to automatically signal when to start and stop a generator. Here is advice on when to use which product and method. Various Victron products have functions to automatically signal when to start and stop a generator.

 +=== Option 1: Venus-device like CCGX or Venus GX ===
 When there is a [[venus-os:​start|Venus-device]] (CCGX, Venus GX, or other) in the system, the best option is to use its [[ccgx:​generator_start_stop|Generator Start Stop mechanism]]. Its the most feature-rich generator start/stop system that we have to offer. It provides for basic functions as starting and stopping on Battery State of Charge, Battery voltage as well as High load situations. And also has many advanced features, including automatic test runs and silent times. When there is a [[venus-os:​start|Venus-device]] (CCGX, Venus GX, or other) in the system, the best option is to use its [[ccgx:​generator_start_stop|Generator Start Stop mechanism]].

 +=== Option 2: BMV Battery Monitor ===
 The next most used option is a BMV-700 Battery Monitor or similar model. It can start the generator on low battery voltage and/or low battery state of charge. See the [[https://​www.victronenergy.com/​battery-monitors/​bmv-700#​manual|BMV-700 manual]] for configuration. The next most used option is a BMV-700 Battery Monitor or similar model.

-Also the VE.Bus ​Inverters, Multis and Quattros offer a Generator start/​stop ​mechanismThey have the relatively easy to configure ​and quite flexible Generator Start/stop function of the Virtual Switch, or the more advanced [[assistants:overview_of_available_assistants#​generator_start_and_stop|Generator start/stop Assistant]]+=== Option 3: Using the relay in the Multis or Quattros === 
 +The Multis, MultiPlus-IIs,​ Quattros, EasySolars and the rest of the VE.Bus ​family also have Generator start/​stop ​feature with a relayThere are two different ways to configure ​them:
  
 +  - [[ve.bus:​virtual-switch-generator-start-stop|Generator Start/stop function of the Virtual Switch]] (recommended)
 +  - [[assistants:​overview_of_available_assistants#​generator_start_and_stop|Generator start/stop Assistant]] (more advanced / complex)

 +=== Combining the options ===
 Lastly, its of course also possible to combine above mentioned methods, by wiring the open contacts in parallel to each other, or in series, to the Generator. Lastly, its of course also possible to combine above mentioned methods, by wiring the open contacts in parallel to each other, or in series, to the Generator.
  
-===== Starting a genset ​with three-wire interface ​=====+==== 2. How to wire generators ​with three-wire interface ====
  
-For example Cummins/​Onan gensets, ​that need a start pulse and a stop pulse.+All above Victron products and devices have a single relay; which will close when the generator needs to starts; and then expect the generator to then keep running until the relay is opened again. Or the other way around. 
 + 
 +When having a generator ​that requires ​a start pulse and a stop pulse, such as for example Cummins/​Onan generators; additional wiring is required.
  
 To start such a genset, the open/close contact needs to be converted into a start and stop pulse. Below solution, using standard available timing relays, does exactly that: when the open/close contact closes it generates the start pulse, and when the open/close contact opens again it generates the stop pulse. ​ To start such a genset, the open/close contact needs to be converted into a start and stop pulse.
