plug 99 will be at the distal relative to accessory module 90 end of wire connector 98 for output 97 and proximal end of wire connector 98 for input 96 in this orientation the proximal end of wire connector 98 is u201c hard wired u201d into accessory module 90 for output 97 alternatively it is possible to employ wire plug 99 and wire connectors 98 at both ends of wire connector 96 also it is possible to employ a wire with a wire plug 99 or wire connector 98 and a bulkhead connector molded into the accessory module also it is possible to have the input 96 and output 97 both be molded in connectors allowing the customer to control the wire length preferably wire plug 99 is mc4 from multi contact of windsor calif in use one could either purchase solar panel 70 with junction box 10 already mounted or retrofit existing solar panel 70 by affixing junction box 10 with junction box 10 in position module 90 is engaged with engagement platform of junction box 10 the same is performed for other solar panels 70 in string 65 the specific modules 90 selected for each panel 70 depends on the particular circumstances for example a panel which is often in the shade might benefit from a boost controller part number stg mlm2 4 from tigo energy while a panel that requires monitoring or switching capability might benefit from a mppt accessory module part number spm1258a s from solar power technologies furthermore a panel that requires ac output.
