I have a 5kva Multiplus connected to a 48v 300Ah lead acid battery bank. There is a roughly 0.8v drop between what battery voltage the inverter sees as displayed on VeConfigure and actual battery voltage. E.g Multi reads 49v whereas battery reads 49.8v when measured with a multimeter at battery and inverter terminals.
I have connected the Voltage sense cables to the appropriate terminals but these seem to have no effect on the Multiplus' voltage readings. I even restarted the Multiplus a few times and no improvement in its voltage readings (still off)
The voltage sense terminals that fit into the Multiplus have ferrules about half inch long crimped on them - I am beginning to think I need longer ferrules?
There is no GX device or BMV in this config as it is a simple backup system. I need a reliable means to read the correct voltage as the low battery cutoff and absorb and float setpoints absolutely need an accurate reading.
