AC Solar With DC Solar

Hope somebody can assist me I am new to using Victron however I am a qualified electrician, and I have recently bought a house with an existing installation, I have an grid fed Multiplus 48/5000 70-100 together with an SMA Sunnyboy providing Solar AC, I have recently upgraded my battery bank to a big Lithium ion pack but now the problem I am sitting with is that the solar array isn't sufficient enough to recharge the batteries during the day so I would like to add an Victron MPPT with a few extra panels. I have an Colour Gx in the system, now my question is do I just install the MPPT and connect it to the DC side of the Multiplus ? and connect the comms to the VE.direct ? is there anything else I must do beforehand?

Other than programming the mppt for your battery bank, you will be all set.

There is also a channel on YouTube with instructional videos if you are more of a video person.


Adding a DC mppt should have been done in any case, its just good practice.

If you have not purchased anything yet a good place to check on sizing is the below linked page.
