XLP USE is a cross-linked polyethylene insulated single conductor stranded or solid bare copper wire. It is similar to XHHW building wire except this product is rated for direct burial applications. This product is also referred to as RHH/RHW meaning it meets the UL standard 854 for service entrance cable.

Battery Cables

Copper 6AWG is rated to carry 100 amps (https://www.powerstream.com/Wire_Size.htm). 100 amps at nominal 24v is 2400w.

"100A / 24V with a 2-3Kw Inverter should be using 2/0 wire and something "fine" like high grade Welding Wire which is extremely flexible, strong, chemical & wear resistant." (source: diysolarforum.com)

Connectors

Anderson (SB, Powerpole/PP)

SB 50 - UL Rated for Hot Plugging up to 50 Amps. Allows UL rated currents up to 120 amps.

SB 120 - New extended range contacts expand wire size up to #1 AWG (42.4 mm²). Allows UL rated currents up to 240 amps

SB 175 - Standard Housing uses up to 1/0 (50mm2) wire and allows currents up to 280 amps, SB 2/0 housing allow s use of 2/0 (70mm2) wire and handles up to 340 amps, UL rated for Hot Plugging up to 100 amps

PP75 - up to 120 Amps, 6-16 AWG

PP120 - up to 240 Amps, 1/0 (50 mm²) to 8 AWG

XT-60 - Will Prowse' favorite. Rated to 65A, but tested to 180A with 12 AWG. 10 AWG won't fit.

XT-90 - Can handle higher amps than XT-60 (rated 90A). Can fit 10 AWG.
