-===== Solar and wind priority =====
+[[solar-and-wind-priority|moved here]]
-NOTE: this is a new feature that is being rolled out in steps:
-  - VE.Bus Firmware, implement float-only feature - done per version 26/27xx504
-  - VEConfigure, add float-only config option - pending. Expected late June 2023.
-  - VictronConnect, add float-only setting & add user control to override it in case a full charge from shore is needed - pending
-  - Venus OS, add user control to override it in case a full charge from shore is needed - pending
-  - VRM Dashboard controls, same - pending.
-In other words, per late June 2023, it is possible to use this feature. A while later, hopefully already in July, we’ll have added the user option to - temporarily - override it for moments when a full charge from shore is required.
-==== 1. Feature description ====
-In VEConfigure, there is a new setting, “limit internal charger to prioritize other energy sources”.
-Enabling that will make the inverter/charger use mains/shore power to charge up to the configured float voltage only. Instead of up to the, higher, configured  absorption voltage.
-This charges the battery enough to prevent premature ageing, while at the same time leaving the rest of the charge up to renewable sources, such as wind or solar.
-When after seven days the battery still isn’t fully charged, the inverter/charger will complete one charge cycle. These seven days are configurable, it is the repeated absorption interval setting.
-The intended application is boats, campers, and so forth that want their solar charger to take care of most of charging when connected to shore power; both while traveling but also when back home.
-For systems with a Quattro, the charge-to-float will only be applied to AC-in-2, the input where we recommend to wire shore. When charging from AC-in-1, recommended to wire the generator, it will make for a full charge. This AC input selection is not configurable. To prioritize solar over charging from the generator, look at options to start the generator early.
-==== 2. Config instructions ====
-TO BE COMPLETED
-Step 1 Requirements
-- update VE.Bus firmware to 504 or higher.
-===
-- if the Storage setting is enabled, then after 12 hours of float, the system will go to storage
-==== 3. Alternative: disconnect from shore automatically ====
-Mostly applicable for larger systems, where the size of the installed inverter is sufficient to power all the loads, there is an alternative solution.
-By using the “Conditonal AC input control” / “Ignore AC input” feature, the Multi or Quattro can be configured to remain disconnected from the shore connection completely. This is described in detail in [[https://panbo.com/maximizing-solar-production-with-victron-gx/ |this blogpost on Panbo.com]]
