Recently I installed some solar panels to my narrowboat. I have a Lithium system with a multiplus 3000. I recently added 8 solar panels and a MPPT 150/100. Since then, whenever the state of charge drops to around 70%, the lithium voltage drops to 11.9ish and the whole system cuts out. I changed my settings in my BMV to 14.4V for charged voltage as I read online. Anyone know what is happening?
Thank you.
