Visit CalculatorThe Windynation 4/0 Gauge (AWG) Battery Cable Set is a premium ultra heavy-duty wiring solution engineered for maximum power transfer in demanding DC electrical systems. Ideal for large solar battery banks, inverter installations, RV systems, marine applications, automotive power systems, backup energy setups, and industrial DC applications, these cables deliver exceptional conductivity, flexibility, and durability for extremely high-current environments.
Manufactured in the USA using highly flexible industrial-grade copper cable, each assembly is precision cut and stripped using automated robotic cable processing equipment. Pure copper tin-coated ring terminals are permanently attached using a powerful 6-ton pneumatic crimping system, creating ultra-secure, low-resistance electrical connections. Adhesive-lined polyolefin heat shrink tubing is applied after crimping to help protect the lug-to-cable interface from moisture, corrosion, and chemical exposure.
Rated for up to 600 volts and engineered to withstand temperatures ranging from -58°F to +221°F, the Windynation 4/0 AWG battery cable set is ideal for inverter wiring, large-capacity battery banks, grounding systems, backup power systems, and renewable energy installations requiring dependable high-current power transfer.

Pure Copper Tin-Coated Lugs - Heavy-duty ring terminals are constructed from pure copper with corrosion-resistant tin plating to help minimize oxidation and extend cable life.
Highly Flexible Industrial Cable - Flexible 4/0 AWG cable simplifies installation and routing in battery compartments, inverter cabinets, RV systems, marine applications, and large backup systems.
Professional 6-Ton Pneumatic Crimping - Cable lugs are permanently attached using a high-pressure pneumatic crimping process for superior durability and low electrical resistance.
Moisture-Resistant Heat Shrink Protection -Adhesive-lined polyolefin heat shrink tubing helps seal the lug connection point against moisture and chemical exposure.
600V Rated Cable - Approved for up to 600 volts, making these cables suitable for a wide variety of DC electrical and energy storage applications.
Extreme Temperature Durability - Designed for harsh environments with an operating temperature range from -58°F to +221°F (-50°C to +105°C).

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.

I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!

I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
