-===== 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.
-  - 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 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 float voltage only. Instead of up to the usual 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.
-By using shore power to charge up to the configured float voltage, the battery is charged sufficiently to prevent premature ageing by leaving it in a discharged state. In case there is not enough solar in the system. The inverter/charger will finish the charge in the next repeated absorption interval, which by default is configured to occur every 7 days.
-Target: boats, campers, and so forth that want their solar charger to take care of most of charging when connected to shore power; either while travelling but also when back home.
-And that want the Multi to be there as a backup to make sure batteries are not left alone in case there is no or not enough charger; and want an option in their enduser-controls to force a charge whenever they need it.
-Details:
-- for a Quattro, this will only work when connected to AC-in-2, since AC-in-1 is where a generator is connected and while that is running you want to charge with full power.
-- if storage is enabled in its settings, then after a hardcoded 12 hours go to storage
