Find the right type of solar component before replacing a rooftop Y-connector, inline fuse or array disconnect. A Go Power 67049 branch, a Renogy 0022121 fuse and an AIMS 1005959 switch are not substitutes for each other: they connect, protect and isolate different parts of the solar circuit.
Where each kind of connector belongs
When multiple compatible PV modules are wired in parallel, correctly matched branch connectors bring their output together. Any required string overcurrent protection and DC-rated disconnection must be selected for that array. The controller then manages battery charging according to its own input limits.
Combines parallel panel currents. The SC-BC-1M2F and SC-BC-1F2M differ in connector gender and work on opposite polarity sides of an approved arrangement.
An inline 20A solar fuse is not universal. Its rating must match conductor protection, the PV module's maximum series fuse rating and array design.
A DC-rated switch permits array isolation when properly installed. Voltage, current, poles and circuit configuration must match the actual PV system.
Model-number reference
| Exact component | Identification | Role |
|---|---|---|
| Go Power SC-BC-1M2F / 67049 | 1 male / 2 female | A branch connector of one polarity orientation |
| Go Power SC-BC-1F2M / 67050 | 1 female / 2 male | The matching opposite-polarity branch |
| Battle Born BBCBL-47 | 4-to-1 connector pair | For combining parallel solar leads, where approved |
| Renogy 0022121 | 20A inline fuse assembly | String overcurrent protection when specified |
| AIMS DC1200V32A / 1005959 | PV-rated DC disconnect | Isolation equipment; must match actual array conditions |
| AIMS DC1600V32A2IO / 1004532 | Dual-input/output DC disconnect | Different model and connection arrangement |
Connector housings that appear to fit are not automatically approved mating pairs. Check connector manufacturer, rating and contact compatibility. The number and direction of branches must be determined from the solar panel and controller installation instructions, not from connector appearance.
