Upgrading my 75/15 mppt

Hi ! I have a keystone travel trailer with the solarflex package. I have a 200 watts panel on the roof with the 75/15 mppt controller. I also have 6 volts battery of 215amp / hours I want to add a 200 watts panel. Is the 100/30a is the right choice for me ? Thanks !

Victron MPPTs are for 12 and 24V systems, with some suitable for 48 V systems.

There isn't a 6V model.

Maybe you are thinking of 2 6V batteries wired for 12V?

Use the MPPT Calculator with the actual values of your panels.

It's possible that you can use a second panel 2S1P or 1S2P without a new MPPT. That depends on your modules.

It appears that their MPPT calculator allows only "Victron solar modules: " data

Not true. You can enter non Victron panels in.
