Hi, I recently obtained 2 x Blue Nova 108Ah Lithium batteries for off the grid camping, Fitted a Victron Smart Shunt and working with a MPPT and 300W Solar panel.
In bright sun the current into the shunt is only 7,5A (half it should be), I have also tested a different 300W Solar panel, same current. Then I connected the 2 Panels in parallel and the current were 15A, still half it should be
Today I connected the Batteries on my Victron blue power 12v 15 A and the charge changes almost immediately from bulk to absorb. Why? the batteries are 50% SOC.
