- | + | ||
- | NOTE: this is a new feature that is being rolled out in steps, and currently in beta. We'll be testing this over the summer period; and once stable announce it officially. | + | |
- | + | ||
- | Status of the roll-out is that its usable with beta versions. In detail: | + | |

- | ===== 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. | + | |
- | * 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 | + | |
- | * 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 more traditional systems 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. Installation of beta versions and firmware ==== | + | |
- | + | ||
- | * Download VictronConnect beta version v5.92, or later, | + | |
- | * Use that version of VictronConnect to update the inverter/ | + | |
- | * Alternatively update remote using the VRM Portal - TODO ADD BETA DOWNLOAD LINK. For now, VictronConnect beta is the only source for the new 506 firmware, therefor the firmware update through VRM option is not possible at the moment. See [[https:// | + | |
- | * To update the GX device to a beta version, see here: https:// | + | |
- | * In case you need to use VEConfigure (in most cases not necessary, use VictronConnect instead), the install it using these instructions: | + | |
- | + | ||
- | + | ||
- | ==== Step 2. Configuration ==== | + | |
- | === VictronConnect === | + | |
- | + | ||
- | The setting is available in VictronConnect in the advanced tab of the settings: | + | |
- | + | ||
- | {{ : | + | |
- | + | ||
- | === VEConfigure === | + | |
- | + | ||
- | 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%. | + | |
- | + | ||
- | For Lead ... ? | + | |
- | + | ||
- | === Step 3 - Check further settings === | + | |
- | + | ||
- | - if the Storage setting is enabled, then after 12 hours of float, the system will go to storage as usual | + | |
- | + | ||
- | - repeated absorption interval, defaults to seven days. | + | |
