Freedom XC PRO 3000 (818-3010)
See the Xantrex Freedom XC PRO 3000 120V 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.
4.6 ft one way
12 V system
Sized against ABYC E-11. The design current is the part's continuous draw. 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 example covers only the 12 V battery connection for standard model 818-3010. It uses the manual's 4/0 AWG minimum (120 mm² in this catalog), a 350 A Class T fuse and 1.4 m conductors each way, below the manual's 1.5 m limit. The 304 A value is published nominal full-load DC input. Verify actual battery/BMS capability and the complete AC, grounding, transfer and installation requirements separately.

Guidance for this model, with sources linked beside the relevant advice.
Verified against the manufacturer's documentation (rev. 975-0799-01-01 Rev G; standard 818-3010 3000W / 150A column), checked 2026-10-01. Manufacturer documentation →
This entry is the standard Freedom XC PRO 3000, 818-3010, with 12 V battery input, 3000 W continuous AC output and 150 A charging. The Rev G specifications publish 304 A nominal DC input at full inverter load. Marine variants and the non-PRO Freedom XC must not inherit this model’s details indiscriminately.
Printed page 21 calls for 4/0 AWG, each one-way battery cable under 1.5 m / 5 ft, and a 350 A maximum battery fuse. Use a correctly rated battery disconnect and fuse close to the positive source. DC stud torque is 8–10 Nm; the chassis grounding lug has its own lower 2.6 Nm requirement.
Separate AC IN from AC OUT; never backfeed the output from another source. The transfer relay is rated 50 A with 40 A continuous service. AC neutral/earth switching and GFCI compatibility must follow the manual’s application diagram. The 3000 W inverter rating does not mean its DC terminals carry 25 A: that figure belongs to 120 V AC output.
Set battery chemistry, charging current, low-battery behavior and available AC input current. Confirm the battery/BMS can support inverter demand and accept charging. Test both shore-powered charging and loss-of-shore transfer with a suitable load. Preserve ventilation and use the additional drip-protection installation requirements when fitting the standard model in a marine application.
Build it out
Add Freedom XC PRO 3000 (818-3010) 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.
