Quattro max charging voltage?

Hi

In the charging settings the VE config the highest voltage possible to be set is 64.4 volt. Is this the upper limit? I would need 65.6 volt if possible. The Quattro accepts 66 volt in the DC inputs.

Have three 15 kVa units.

Merry Christmas!

As I know 64V is the limit and cant be changed.
Why you need such a high voltage?

My battery bank is 65.5 volts (16s8p). When i connected and started up everything i had 2 of the "banks" relays not connected properly and the rest of the pack was used down. In order to be able to connect the two remaining i must get them up to 65.5 volt so i avoid current rush between them. Total capacity is 185 kWh....

Hi @Arke

Maybe you can discharge the other bank?
