- | ====== Generator | + | ====== |
- | There are many ways to automatically start and stop a generator using Victron equipment: | + | ==== 1. Which relay and control to use? ==== |
- | - potential free relay in a BMV-700. Start the generator on low battery voltage and/or low battery state of charge. See the [[http:// | + | |
- | - potential free relay in our Inverters, Multis | + | |
- | - potential free relay(s) in our Inverters, Multis and Quattros, using the [[assistants: | + | |
- | - (Expected in October 2015) [[ccgx: | + | |
- | It is also possible | + | Various Victron products have functions |
- | ===== Starting a genset with three-wire interface ===== | ||
- | To start such a genset, our 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. | ||
- | Note that this solution should only be used on generators | + | === Option 1: GX device like CCGX or Venus GX === |
+ | When there is a [[venus-os: | ||
+ | |||
+ | === 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:// | ||
+ | |||
+ | === Option 3: Using the relay in the Multis or Quattros === | ||
+ | The Multis, MultiPlus-IIs, | ||
+ | |||
+ | - [[ve.bus: | ||
+ | - [[assistants: | ||
+ | |||
+ | === 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. | ||
+ | |||
+ | ==== 2. How to wire generators with a three-wire interface ==== | ||
+ | |||
+ | 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/ | ||
+ | |||
+ | 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. | ||

+ | === Alternative using Assistants === | ||
+ | |||
+ | (provided by Thierry Cortasa) | ||
+ | |||
+ | hi | ||
+ | |||
+ | just for information, | ||
+ | i use k1 and k2 relais and relai programmable assistant | ||
+ | |||
+ | first to close k1 if voltage under 24v (for exemple) | ||
+ | segond to open k1 if ac1 avalable | ||
+ | third to close k2 if voltage uper 27v (for exemple) | ||
+ | last to open k2 if ac1 not avalable | ||
+ | |||
+ | in this case you have a three-wire system with out any think more needed ! | ||
+ | |||
+ | i have some systeme using this solution and all looks ok | ||
