Installing a battery combiner box involves connecting the positive and negative wires from each solar panel to busbars within the box, securing connections with double lugs or studs, and testing the system for proper functioning. What are Battery Combiner Boxes?
Battery combiner boxes are essential components in battery storage systems that allow for the connection and distribution of power between multiple batteries. They serve to efficiently combine the positive and negative wires from individual batteries into a single output, ensuring safe and convenient operation.
Loosen the waterproof terminal nuts at the bottom of the combiner box. Thread positive strings through white cable glands and negative strings through black ones, allowing extra cable length for bending and secure attachment inside the box. Use a wire stripper to expose about 12mm of the copper core.
Ground the combiner box by connecting it to the inverter. Use the grounding points marked with the Open the combiner box cover. Install conduits, as required by local regulations. Maximum supported conduit diameter - 32 mm. Connect the DC cables from the combiner box to the inverter.
1. Choose a suitable location for the combiner box near your solar panels. 2. Ensure that the area is well-ventilated and protected from rain and other elements. 3. Connect the positive and negative wires from each solar panel to the corresponding busbars in the combiner box. 4. Use double lugs or studs to secure the connections for added safety.
Connecting the DC Cables BYD recommends using bootlace ferrules for connecting the DC cables to the blocks. • Moisture can penetrate the Combiner Box through unsealed cable glands. Attach the cables to an external cable support rail. Cut the cables to length and strip 25 mm off the insulation.
