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.

+ | 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. The BMV uses a dry contact, voltage free relay. See the [[https:// | ||

- | + | Use k1 and k2 relays | |

- | i use k1 and k2 relais | + | |
- | + | ||
- | 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 ! | + | |
