Power and communication connections between batteries and HV-BOX
For a new system, we do not recommend installing a mixed solution with mixed 5K3 and 5K3XP batteries.
When using 5k3 and 5k3XP batteries, it is mandatory to:
- Install an
XP HV-BOX
;
- Install
at least one 5k3XP battery
(the 5k3 XP batteries must be installed just below the XP HV BOX, while the 5k3 batteries must be
inserted last).
Channel configuration:
Configure the inverter channels according to the number of HV-BOXES connected to the inverter (see previous paragraphs).
