Product Overview

The RS-2/0A1F3 cable set is designed for customers who need a heavier-duty wiring solution for battery-based DC systems. It is useful for replacing worn cable, upgrading undersized wiring, connecting batteries to inverters, wiring battery banks to busbars, adding grounding connections, or building cleaner DC power layouts.

Because each option includes a matching red and black cable pair with 3/8" lugs, customers can choose the length that best fits their equipment layout without separately sourcing positive and negative cables.

Made for High-Demand DC Power Wiring

2/0 AWG cable is commonly selected for higher-current battery and inverter applications where cable sizing, voltage drop, cable routing, and connection quality matter. These cables are a strong fit for RVs, campers, travel trailers, solar systems, inverter connections, golf carts, car audio power, grounding, and other DC wiring applications.

PVC insulation, moisture resistance, ROHS compliance, UL approval, and a voltage rating up to 600 volts make this cable set a practical option for properly designed DC power systems.

Choose the Right Cable Length

The RS-2/0A1F3 is available in multiple length options so customers can match the cable set to their battery, inverter, busbar, fuse, shunt, or grounding layout. Shorter cables help reduce clutter and voltage drop when equipment is close together, while longer options give more room for routing through compartments and equipment bays.

1ft–2ft Lengths Best for short battery-to-busbar, battery-to-battery, fuse, shunt, or nearby inverter connections.
3ft–4ft Lengths Useful for routing through battery compartments, inverter bays, RV storage areas, and compact DC distribution layouts.
5ft–6ft Lengths Better for longer cable paths where the battery, inverter, busbar, grounding point, or DC accessory is mounted farther away.
Cleaner Install Planning Selecting the correct length helps avoid excess slack, sharp bends, tight cable pulls, and awkward routing.

Built for Battery, Inverter, Solar, and Vehicle DC Systems

These cables are best for customers who need a heavy-duty red and black cable set for power transfer between batteries and DC equipment. They are especially useful when replacing old cables, upgrading battery wiring, or building cleaner battery-to-inverter, battery-to-busbar, grounding, automotive, or solar system connections.

RV & Camper Wiring A heavy-duty cable set for RVs, campers, travel trailers, and mobile power builds that need dependable DC wiring.
Solar Battery Systems Useful for battery-bank wiring, busbar connections, inverter wiring, and off-grid solar power projects.
Automotive & Motorcycle Use Built for replacing or upgrading DC wiring in cars, motorcycles, car audio systems, and grounding applications.
Golf Carts & DC Accessories A strong fit for golf carts, auxiliary power systems, and other battery-powered DC applications.

Key Features That Matter

🛡️
PVC Insulation Protection

Polyvinyl chloride insulation helps protect the cable during everyday DC power use in vehicles, RVs, solar systems, inverter setups, and battery projects.

✅
UL Approved & ROHS Compliant

UL approval, ROHS compliance, VW-1 rating, and moisture resistance give customers added confidence when choosing cables for battery upgrades and DC electrical projects.

Insulation and Protection Details

The RS-2/0A1F3 cable set uses polyvinyl chloride insulation with a voltage rating up to 600 volts. It is listed as VW-1 and moisture resistant, helping support dependable use in battery, inverter, solar, vehicle, and DC wiring environments when installed properly.

The page also lists heat-shrink related specifications including an approximate 3:1 shrink ratio at 194°F, an operating temperature range from -67°F to +275°F, dielectric strength of 500 V/mil, volume resistivity of 10¹⁴ ohm-cm, and tensile strength of 1500 psi.

Designed for Practical DC Upgrades

These cables are useful when customers are upgrading a battery bank, adding a power inverter, improving grounding, replacing older wiring, or building a cleaner connection between batteries and DC equipment.

As with any high-current DC wiring, the cable gauge, fuse or breaker size, lug fitment, routing, protection, and terminal torque should be matched to the system design before installation.

Frequently Asked Questions

Clear answers to common questions about this product, setup, compatibility, and use.

What hardware must match the 3/8-inch lugs on the 2/0 battery cables? Both cable ends use 3/8-inch ring lugs. Check that the battery, busbar, fuse holder, shunt, or inverter studs accept that opening and can clamp the lug fully at the specified torque without washers or adjacent terminals interfering. What cable-run choices are available for the RICH SOLAR 2/0 AWG pair? The product is offered in 1-foot, 2-foot, 3-foot, 4-foot, 5-foot, and 6-foot lengths. Because a DC circuit includes both directions of current flow, include the complete positive and negative path when evaluating voltage drop. Is upgrading to 2/0 cable enough to cure inverter low-voltage shutdown? Not by itself. Larger cable can reduce conductor loss, but shutdown may also come from battery voltage sag, a restrictive BMS, loose lugs, undersized fuses or busbars, excessive length, or inadequate bank capacity. Diagnose voltage at the inverter while the load is operating. How broad is the stated operating-temperature range for these 2/0 cables? RICH SOLAR publishes -67°F to 275°F for the cable assembly and identifies the PVC insulation as moisture resistant. Installation near heat sources, moving parts, sharp metal, or corrosive battery vapors still requires suitable protection and support. What protection belongs in a high-current circuit using 2/0 battery cable? Use a fuse or breaker sized to protect the conductor and permitted by the connected equipment, installed close to the source as applicable. The 600V cable rating and large conductor size do not eliminate the need for overcurrent protection, secure routing, insulated terminals, and a safe disconnect.
