MC4 & Tyco Preassembled Cables / PV Panel Connectors

These cables have the newer, snap-together Multi-Contact hard plastic connectors on each end. Use these output cables between PV arrays with Multi-Contact cable outputs, and junction boxes or grid-tie inverters. They the PV wire have a male connector on one end and a female connector on the other end. Use them to extend module output cables or cut anywhere along the wire to obtain the needed length of male and female cable to run from the ends of a module string to a combiner box or to an inverter. For example, if you need a 30' male and a 20' female, order a 50' cable. These cable connectors are fully waterproof when connected, touch-protected but cannot be safely disconnected under load. Due to the lack of a standard for connector geometry, a myriad of varying brands and styles of connectors are used by solar manufacturers, and most of them are not interchangeable. The cable assemblies presented here feature the most commonly used connectors. Made with black #10 AWG USE-2 sunlight resistant cable.

battery cableWhy Use Larger Cable? Low-voltage solar systems with inverters can have very high current (amps) through the cables that connect the inverter to the batteries. Large AC loads like microwave ovens, toasters, irons, and washers can cause an inverter operating on a 12 VDC battery system to draw over 100 A. Large motors may draw 300 to 500 A during startup. When cables between batteries, and from the battery bank to the inverter, are too small, the current available to the inverter is limited and it may fail to supply larger loads. Properly sized cables also impose less resistance and thereby help maximize your solar systems efficiency.

 

Inverter Battery Cables with Lugs

Use these cables between a battery bank and inverter, fuse or power center, or battery bank to connect one battery to another in parallel or series. They have flexible stranded UL Listed copper wire and 3/8" diameter lugs. Lug barrels are covered with glue-filled heat-shrink tubing. Cables are marked in red heat-shrink tubing specify red or black.

battery cableUse these cables between individual battery cells or between battery banks. Circuits protected by 250-amp breakers or 400-amp fuses should use 4/0 cables. Use 2/0 cables for 175-amp breakers and 200-amp fuses. Use #2 cables for 110-amp or smaller fuses or breakers. NEC code requires battery cables to be listed for hard service use and mosture resistant. NEC 400 also requires that battery cables be flexible. Flexible cables put less stress on battery terminal connections.

 

Battery Interconnects

Use these cables between individual battery cells or between battery banks. Circuits protected by 250 A breakers or 400 A fuses should use 4/0 cables. Use 2/0 cables for 175 A breakers and 200 A fuses.
