2/0 AWG DLO Inverter Battery Cable Set

Built for serious power delivery and durability, this pair of 2/0 AWG DLO battery interconnects uses highly flexible, tinned copper conductors with rugged insulation. Both cables are black for a clean, uniform look, with one red-tagged for positive. Each end is terminated with CSA-listed 3/8 in tinned copper lugs. Rated 195 A continuous and engineered to resist ozone, sunlight, oil, grease, weather, chemicals, and abrasion, this set is ready for inverter to battery hookups and battery bank interconnects.

How this set works with inverters and batteries

Primary inverter leads

• Connect one cable from the inverter’s DC positive to your battery bank positive (through a properly sized Class-T fuse or breaker), and the second cable from inverter DC negative to battery bank negative or a negative busbar. The 3/8 in lugs fit most 48 V inverter and rack battery studs.

Battery bank interconnects

• Use as series or parallel jumpers between batteries and busbars for low-resistance links. The flexible DLO construction reduces strain on battery studs and helps with tidy routing in tight racks.

System voltages and typical sizes

• 2/0 AWG at 195 A continuous is well suited for many 48 V inverter installs up to about 6 kW continuous, and up to roughly 8 kW when cable runs are short and protection is sized correctly. Larger inverters or long DC runs usually require 4/0 AWG. Example 6,000 W at 48 V and 90 percent efficiency draws about 139 A.

Voltage drop and length

• The listed lengths are chosen to keep DC voltage drop low on typical inverter placements near the battery rack. Shorter is always better. If your inverter is more than a few feet from the battery bank, consider upsizing to 4/0 or relocating components.

Use cases

• 48 V inverter to battery connections for cabins, cottages, shops, and off-grid homes

• Parallel links from rack batteries to common busbars

• Upgrades from automotive cable to true DLO for better flexibility and heat performance

Compatibility and fit

• Works with most 48 V inverters using 3/8 in DC studs including EG4, Victron, Magnum, Samlex, and similar

• Fits common server rack batteries that use 3/8 in studs including EG4 LL-S and comparable units

• For very high power inverters such as many 10 to 12 kW models, check the manual. 4/0 AWG is typically recommended for the main DC leads

Key features

• 2/0 AWG flexible DLO tinned copper for low resistance and high strand flexibility

• 195 A current rating suitable for robust inverter and battery bank connections

• Dual black cables with one red-tagged positive for clean, professional routing

• CSA-listed 3/8 in tinned copper lugs, professionally crimped and heat-shrink sealed

• Tough, weather-resistant construction that stands up to sun, oil, chemicals, and abrasion

What you get

• 2 × pre-terminated 2/0 AWG DLO battery cables in your selected length

• Factory-crimped 3/8 in tinned copper lugs on each end

• One cable red-tagged for positive identification

Installation notes

• Always use a properly sized Class-T fuse or DC breaker on the positive lead near the battery bank. For 2/0 AWG protection, a 200 A device is a common choice when appropriate for your inverter and wire ampacity.

• Torque all lugs to the inverter and battery manufacturer’s specs and recheck after initial thermal cycles.

• Keep DC runs as short and straight as practical. Use busbars for multi-battery layouts to ensure even current sharing.

• If your inverter continuous rating or cable length pushes beyond 2/0 limits, step up to 4/0 AWG.
