See the Renogy P2 2000W 12V Inverter connection points and wiring example. Open the diagram in Crimp to add your equipment and plan the cables between them.
Open this example as a new project. Use your own parts and cable lengths to make the plan yours.
Use the diagram as a starting point for your installation. Replace the example equipment and cable lengths with your own, and check the connections against your exact model's instructions.
10 ft one way
12 V system
Sized against ABYC E-11. The design current is a catalog planning estimate for inverter operation at nominal battery voltage, not a measured draw. Actual current changes with load, battery voltage and efficiency. Check the exact model's cable, fuse and installation requirements. The length is one way; voltage drop includes an equal-length return.
The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.
The DC example uses Renogy's 250 A battery fuse. Its 196.1 A design demand is calculated from 2000 W at 12 V and 85% efficiency, not a measured draw. Lower battery voltage increases demand. Check actual cable length, battery/BMS capability, DC connections and the manual's installation requirements; AC outlets, protective earth and appliance starting loads need separate review.

Guidance for this model, with sources linked beside the relevant advice.

The US P2 2000 W produces 115 V / 60 Hz AC from a 12 V battery and offers a 4000 W, one-second AC surge. It has no charger or shore-transfer input. Do not use wiring instructions for Renogy’s PUH/UPS or inverter-charger models.
Manual pages 29–30 list 166.6 A battery current, exactly 2000 W ÷ 12 V, while separately specifying greater than 85% full-load efficiency. That current row omits conversion losses. The catalog therefore uses a labeled 196.1 A planning estimate: 2000 ÷ (12 × 0.85). Actual current depends on battery voltage and load; lower voltage requires more current. No independent terminal ampacity or DC surge is inferred from the fuse.
Connect the battery through an external disconnect and the manual’s 250 A battery fuse, checking conductor ampacity and route. Printed page 21 gives 14 ±0.5 Nm at the DC terminals. Connect the chassis grounding point and wire AC loads only to the AC output; receptacles and terminal-block loads share the same total rating.
Start with AC loads switched off, energize the inverter, then add loads while checking battery voltage at its terminals. Set the switch to REM when using the wired remote. A low-voltage alarm under load can indicate cable drop even when resting battery voltage looks healthy. Keep ventilation clear and isolate both sides before servicing: the off switch does not discharge internal capacitors immediately.
Build it out
Add RNG-INVT-2000-12V-P2-US to your diagram, then connect your batteries, chargers and loads. Crimp calculates cable sizes and checks the connections as you draw.
Every cable you draw there is sized against ABYC E-11, from the same tables as the reference on this page.
Technical reference
Check the model, ratings and connection points against your own unit before choosing installation hardware.
Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.
Catalog connection points, current direction and planning limits. Check the manufacturer's pinout and connector ratings before installation.

Method & provenance
Manufacturer specifications describe the equipment. Crimp calculates cable results from the circuit and assumptions you enter.
From the maker
Manufacturer, model, ratings and which terminal does what come from the catalog. A newer revision, or the nameplate on the unit in your hand, can say something different — when it does, the nameplate wins.
ABYC E-11
Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The run length and the current above are what drive the result. Crimp doesn't know how warm your space gets; draw the cable inside an engine-bay zone on the canvas and it sizes for the heat.
