The original Go Power GP-IC-2000-12 and GP-IC-3000-12 inverter/chargers share the same series of controls and terminals, but require different high-current battery cabling. This parts-reference guide identifies all 17 factory-numbered features, explains the ports and connects them to matching catalog items.
Find the AC, DC and control connections
Use the numbered group locator to distinguish the AC cable access, high-current battery posts, remote cable port and battery-temperature sensor socket. The actual connection locations are shown on Go Power's original numbered factory drawing.
All 17 factory-numbered unit references
| No. | Feature / port | What it does |
|---|---|---|
| 1 | AC cable entry/exit | Separate cable passages and strain relief for input and inverter output wiring |
| 2 | DC chassis ground | The inverter/charger housing's protective DC grounding point |
| 3 | Remote control port | Port for the matching GP-ICR-50 remote cable |
| 4 | Battery temperature sensor port | Socket marked BATTERY TEMP for the included BTS cable |
| 5 | Mounting flange | Secures the housing to an approved installation surface |
| 6 | Negative DC terminal | Connects to battery negative with the specified high-current cable |
| 7 | Positive DC terminal | Battery positive connection, protected by an external DC fuse or breaker |
| 8 | Intake vents | Supplies cooling airflow; keep the openings clear |
| 9 | Status indicator | Light used to indicate operating and fault conditions |
| 10 | Inverter/charger mode indicator | Shows whether inverter or charging operation is selected |
| 11 | Power on/off button | Controls operation but does not isolate battery or incoming AC |
| 12 | DIP switch bank | Reserved on the referenced IC series hardware; not a user wiring connection |
| 13 | Exhaust vents | Rear cooling outlet that must remain unobstructed |
| 14 | Serial/model label | Model, serial and manufacturer rating reference |
| 15 | CB1 / CB2 input breakers | Protect the unit's AC input/transfer circuitry; not branch circuit breakers |
| 16 | AC terminal access cover | Service cover for the hardwired AC terminal block |
| 17 | Built-in handles | Lifting and handling points for mounting or removal |
IC-2000 versus IC-3000: the critical specifications
| Model | Inverter | AC battery charger | AC pass-through | Factory DC protection | Go Power cable kit |
|---|---|---|---|---|---|
| GP-IC-2000-12 | 2000W | 100A | 2 × 50A | 2/0 AWG, 300A Class-T | GP-DC-KIT4 |
| GP-IC-3000-12 | 3000W | 125A | 2 × 50A | 4/0 AWG, 400A Class-T | GP-DC-KIT5 |
Both models use a 12V battery system and have a built-in automatic AC transfer function. The 50A legs describe external AC pass-through—not 50A of battery-powered inverter output on each leg. The controller and remote settings must be matched to the unit's exact production revision.
Go Power's IC manual specifies short battery cable runs with an external DC fuse or breaker and disconnect. Cable sizing and cable-length limits for the installed unit take priority over a generic inverter-kit wattage chart.
Matching inverter, solar system and DC parts
These are exact-number catalog listings. A complete inverter/charger package or boxed solar system may already contain the control accessories; the DC cable kits are separate installation products.
