Before replacing a Go Power inverter/charger, check the unit's rating label and connector arrangement. The legacy IC2000 and IC3000 models have familiar-looking ports, but their DC protection and inverter wattage differ. Use the manufacturer's numbered component identification below to locate the original equipment.
How to recognize the original IC-series housing
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.
Original IC-series component identification
| 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 |
Which size of IC inverter/charger do you have?
| 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.
