====== Solar and wind priority ====== | ====== Solar and wind priority ====== | ||
- | + | The old Solar and Wind Priority manual | |
- | ===== 1. Introduction | + | |
- | + | ||
- | Solar & wind priority gets to work when plugged into shore. It then ensures that solar & wind power are used to charge the battery, while the shore power is only used to prevent the battery from becoming too deeply discharged. | + | |
- | + | ||
- | It stays in this mode, called Sustain, for seven days; and if by that time there has not been enough solar or wind, it will run a full charge cycle, charging the batteries to 100%. This will make sure they stay in an optimal condition as well as be ready for a next use. | + | |
- | + | ||
- | After those seven days, the system will not go back into sustain mode. Instead it will keep the batteries fully charged; and, where and when possible, during the day prioritise solar over shore power to power DC loads such as pumps and alarm systems. | + | |
- | + | ||
- | The intended applications for Solar and wind priority are boats, campers and other systems that connect hook up to shore power. | + | |
- | + | ||
- | For systems with a permanent utility connection, such as houses, farms and other stationary systems, we have a different solution: [[https:// | + | |

- | ===== 2. Details and requirements ===== | + | |
- | + | ||
- | Requirements: | + | |
- | + | ||
- | * Victron inverter/ | + | |
- | * Solar, preferably a Victron solar charger, but not necessarily. Or a wind generator with a designated charger. Note that Victron does not supply charge regulators for wind generators. | + | |
- | * To use the " | + | |

- | Further details and specifications: | + | |
- | * While in sustain mode, the inverter/ | + | |
- | * For charging the battery, as well as powering DC loads, solar and wind are prioritised. For AC loads that is not the case, shore power will be used to power them. Which in many systems is not really an issue, since they are small - or the available and solar and wind won't be sufficient. In case you do prefer to also power AC loads from the battery, solar and wind - then look into our Ignore AC input options, in VictronConnect available as the " | + | |
- | * The feature works purely on voltage, making it simple, robust and effective. It does not require an integration with battery monitors, GX devices or central control mechanisms such as DVCC. | + | |
- | * Generator support: the system will automatically detect that a generator is running; and then charge at full power as usual. For Quattros, it requires the generator to be wired to the AC-in-1 input. And in case of Multis with an external transfer switch wired in front of it, the GX device | + | |
- | * On a Quattro AC-in-2 should be used for the shore power connection. | + | |
- | * The Solar and Wind priority mode works both for systems with a managed battery, where a BMS is managing the charge process (DVCC), as well as systems using lead batteries, or Lithium drop-ins, where the inverter/ | + | |

- | ===== 3. Configuration instructions ===== | + | |
- | + | ||
- | WARNING: updating the firmware of this product range, as well as making configuration changes, is strongly advised to be carried out by trained personnel only. Doing the update will cause all settings to be reset to their default: we therefor advise to save the settings before updating and after updating reinstall the configuration. | + | |
- | + | ||
- | ==== Step 1. Install required firmware versions ==== | + | |
- | + | ||
- | * Update the inverter/ | + | |
- | * Systems with a GX device: update to v3.10 or later. See user manual for instructions. | + | |
- | * Systems with a VE.Bus Smart dongle: update to v1.16 or later, using the VictronConnect App. | + | |
- | ==== Step 2. Configuration ==== | + | |
- | + | ||
- | The required setting is in the inverter/ | + | |
- | + | ||
- | === When using our VictronConnect software: === | + | |
- | + | ||
- | The setting is available in VictronConnect in the advanced tab of the settings: | + | |
- | + | ||
- | {{ : | + | |
- | + | ||
- | === When using the VEConfigure software: === | + | |
- | + | ||
- | The setting is enabled in VEConfigure, | + | |
- | + | ||
- | {{ : | + | |
- | + | ||
- | These are the recommended sustain voltages: | + | |
- | + | ||
- | ^ System voltage ^ LiFePO4 ^ Lead (AGM, Gel) ^ | + | |
- | | 12V | 13.0V | Float minus 0.2V | | + | |
- | | 24V | 26.0V | Float minus 0.3V| | + | |
- | | 48V | 52.0V | Float minus 0.4V| | + | |
- | + | ||
- | For Lithium, setting Sustain to 13.0V, which equals 3.25V per cell, makes the system maintain a minimum state of charge of approximately 30%. | + | |
- | + | ||
- | === Other related settings === | + | |
- | + | ||
- | * __Storage mode__: this setting works as usual. When enabled, the inverter/ | + | |
- | + | ||
- | * __Repeated absorption interval__: with Solar and wind priority enabled, this setting controls both the duration of the initial Sustain mode, as well as the repeated absorption interval. Increase this setting in case it is preferred to keep the system in Sustain for a longer time - allowing more days for solar and wind to charge the battery before falling back to shore. | + | |
