Hello All,
I am updating my RV power system to lithiums. I am thinking to use Phoenix Smart IP43 Charger to replace my old stock one. I need some help to understand the basic setting:
Will IP43 charger "Automatically" change its status from "Charger" to "Power Supply" after battery is fully charged and RV does have loads running (like camping)?
Thank you!
cztexas. I have been using the same charger, and remember the following. If you leave the charger "ON", it will charge the batteries. Now, when you put load on the batteries, the charger will continue to provide power to the batteries, as long as the current draw from the charger is not higher than it's maximum rating. If it reaches it's maximum rating, it will turn off.
Thank you for your response. While what I want to know is IP43 have two working states: Power Supply and Charging. You can manually change it in Victron Connect App. But is there anyway that we can let IP43 switch it automatically (like detecting there is load connecting the system)?
Since you have been using this, how do you like this charger? comparing with other popular ones like progressive dynamics?
Thank you!
Switching is controlled by rebulk offset setting in the battery settings expert mode.
P.s. If there is load on the batteries, the voltage drops. This gives the charger the trigger to start charging "bulk", which is essentially a power supply parallel to your batteries.
Thank you!
It would be a good feature to Auto turn from Charger to Power Supply mode after its fully charged the batteries, this will stop micro cycling the batteries! i.e. if you are using a Charger and Separate Inverter to power your boats AC (as i will be) the charger is effectively powering the Inverter and that's what you want! but if batteries are full they will drain off before the charger kicks back in again. An option maybe to set a slightly higher Storage mode voltage to limit this and allow the Charger to take over as soon as the inverter draws a load before it has to come from the batteries.
