SOLAR SETUP TO CHARGE LITHIUM ION BATTERIES (24v 11a)
I want to start a new project. I am completely new in this field. My only concern is that the charging current should not exceed 4 amps in any manner. I have even heard that the voltage should not exceed 30 volts.
Kindly provide me inputs on the same especially about the solar panel rating and mppt charge controller ratings which I should use.
Thanks

@Sanat Rath, all of Victron's SmartSolar MPPTs have completely customizable charge profiles, including voltage as well as max charge current. So, as an example, you could easily hook 2 or 300 watts of PV input into a SmartSolar MPPT 75/15; when you connect it to your battery bank, the MPPT will auto-range to your battery voltage at 24v nominal (which will typically leave you charging at around 27-28v) and you can use the VictronConnect app to set the MPPT max charge current to 4A as desired, rather than the 15A default charge rate.
