Cable size verification for a cluster composed by 5 or more Battery Modules connected to the inverter with 2 sets
of cables (50mm² each) for a total of 100 mm² each terminal (positive and negative).
When more than one battery is connected in parallel we suggest to use a capacity reduction factor of 2% to
calculate the Cluster Capacity at the first installation.
When used in Cluster the Initial Capacity is calculated in 5.2kWh per Module.

ATTENTION
The Battery Terminal Block can support max 50/75mm² on each connection point (two each pole).
It is compulsory to set the maximum inverter current in accordance with the output cables
capabilities.
Cable sizing need to be performed by a local electrical engineer
ATTENTION
Cable sizing must be calculated by a qualified technician/engineer, based on local regulations,
and in accordance with overall system design.
