Hello,
I would like to charge a 12V lead acid battery from a 24V supply net. Victron has Chargers design for this purpose. However, they all have the problem that there is no current limit configurable.
In my use case, I need to limit the input current to about 1.5A. This is not possible with the Orion TR and others.
However, it is possible with the smart solar chargers by limiting the output current, which is configurable.
But there is the following note in the data sheet:
My 24V source is able to deliver more than 20A of current for a few seconds.
In another version of the data sheet I found that:
datenblatt-1924460-victron-energy-scc075015060r-laderegler-mppt-12-v-24-v-15-a.pdf
In english: A higher short circuit current can damage the controller in case of reverse polarity of the solar modules.
Reverse polarity is not problem in my use case.
What are your thougths? Can I do this or do you have better ideas?
