DC Connection
When two or three battery systems are connected, the positive power cable length of all the
battery systems should be approximately equal, and so are the negative power cables. A
junction box or Y-Bridge connectors are needed to combine these cables. You can refer to
Battery-Box Premium HV Combiner Box Basic Technical Requirement, which is available at our
website. Please also follow the local, state, provincial, federal, or national laws, regulations, and
instructions from the inverter manufacturer to choose the right junction box or Y-Bridge
connectors.
Additionally required mounting material (not included in the scope of delivery):
Two DC power cables
Cable requirements:
•
Conductor cross-section: 6 to16 mm
²
. The diameter of the cable should be between 4 mm
to 9 mm. Follow the requirements of the inverter manufacturer.
•
Insulation stripping length: 16-18 mm
•
Maximum cable length: 20 m
Procedure
1.
Take off the nut of the cable glands d
and e.
