Visual Description: Diagram shows the inverter charger being mounted with screws through its mounting holes. A measurement indicates 0.27 inches (7mm) clearance.
Step 3. Remove the Cover
First, ensure the On/Off/Remote Power Switch is in the OFF position. Then, turn the two cover screws counterclockwise (by hand or with a Phillips screwdriver) and remove the cover.
Visual Description: Diagram shows the On/Off/Remote switch and the process of unscrewing and removing the top cover.
Step 4. Ground the Inverter Charger
Connect the grounding wire (6 AWG bare wire, M4 terminal) to the grounding point on the inverter charger.
Visual Description: Diagram shows the grounding connection point on the inverter charger and the bare wire being attached.
Step 5. Install a Wired Remote Control
Use the Wired Remote Control to power the inverter charger on or off remotely. Connect it to the COM Port using the RJ12 cable, routing the cable through the grommet.
Visual Description: Diagram shows the RJ12 cable connecting from the remote control to the COM port on the inverter, passing through a rubber grommet.
Step 6. Install a Battery Voltage Sensor
The Battery Voltage Sensor (BVS) measures battery voltage at the terminal to compensate for voltage drops across cables, ensuring accurate battery status readings. Connect it to the BVS port via the COM port grommet.
Battery Scenario A: REGO Battery Kit
Visual Description: Diagram shows the BVS sensor connected to the BVS port on the inverter. It also shows the sensor wires connecting to the battery terminals (positive and negative) via two steps of screw connections.
Battery Scenario B: Normal Battery Kit
Visual Description: Similar to Scenario A, showing the BVS sensor connected to the inverter and then to the battery terminals.
Step 7. Install a Battery Temperature Sensor
The temperature sensor (BTS) measures ambient battery temperature to adjust floating charge voltage. Connect it to the BTS port via the COM port grommet. Mount the sensor securely near the battery.
Do not use the temperature sensor on a LiFePO4 (LFP) battery with a built-in Battery Management System (BMS).
Visual Description: Diagram shows the BTS sensor connected to the BTS port on the inverter and mounted near the battery.
Step 8. Connect the Inverter Charger to a Battery
Battery Scenario A: REGO Battery Kit
Recommended components include the REGO 12V 400Ah Lithium Iron Phosphate Battery, REGO 4 Ports 400A System Combiner Box, NH2 Fuse (400A), and Anderson Adapter Cable (4/0 AWG). These are available on renogy.com.
Steps:
- Install the cable on the Inverter Charger (connect M8 terminals to Battery Positive and Negative Ports).
- Install an NH2 Fuse (400A).
- Install the cable on the System Combiner Box.
Visual Description: Diagrams show the connection sequence from the inverter to the battery via the combiner box and Anderson adapter cable, including fuse installation.
Battery Scenario B: Normal Battery Kit
Recommended components include a 12V Battery, ANL Fuse (400A), Battery Adapter Cables (4/0 AWG x 2), and Fuse Cable (4/0 AWG).
Compatibility: The inverter charger can connect to deep-cycle gel-sealed (GEL), flooded lead-acid (FLD), sealed lead-acid (SLD/AGM), or lithium iron phosphate (LI) batteries.
Steps:
- Install the cables on the Inverter Charger (connect M8 terminals to Battery Positive and Negative Ports).
- Install an ANL Fuse (400A).
- Install the cables on the Battery (connect to battery terminals).
Visual Description: Diagrams show the connection sequence from the inverter to a standard 12V battery via adapter cables and an ANL fuse.
Step 9. Connect the Inverter Charger to AC Loads (Appliances)
Recommended Cable Size:
- 0-10 ft: 6 AWG
- 11-20 ft: 4 to 6 AWG
- 21-30 ft: 4 AWG
Recommended GFCI Spec:
- Unavailable: ≥25A@120V / ≥50A@120V / ≥25A@240V
- Available: (Specific ratings depend on grid power)
Total Load Power:
- Unavailable: ≤3000W @120V
- Available: ≤6000W @120V/240V
Steps:
- Install bare wires on the Inverter Charger's AC Output Port (L1, L2, N terminals).
- Install a GFCI (Ground Fault Circuit Interrupter) and connect it to the AC Loads.
For split-phase 120V/240V grid systems using AC IN L1, L2, and N:
- Output is 240V when connected to L1, L2, and N.
- Output is 120V when connected to L1 and N.
For single-phase 120V grid systems or when no grid power is available, the output is 120V.
Visual Description: Diagrams show bare wires being connected to the AC output terminals of the inverter and then to a GFCI and AC loads.
Step 10. Connect the Inverter Charger to the Grid (Optional)
Recommended Cable Size: Same as for AC Loads (6 AWG, 4-6 AWG, 4 AWG).
Connection Types: AC Generator, Grid Power (Single-phase 120V or Split-phase 120V/240V).
Risk of electric shock! Ensure the grid or AC generator is turned off before connecting.
AC IN port connections vary by grid system type. Single-phase 120V uses L1 and N. Split-phase 120V/240V uses L1, L2, and N.
If no grid contact is available, connect the ground bare wire to the N bare wire. Failure to do so may cause charging/discharging issues and fault alarms.
Steps:
- Install bare wires on the Inverter Charger's AC Input Port (L1, L2, N terminals).
- Install bare wires on the Grid (L1, L2, N, PE terminals).
Visual Description: Diagrams show bare wires being connected to the AC input terminals of the inverter and then to the grid power source.
