### ⭐⭐⭐⭐⭐ Work great
*by B***N on 15 November 2025*

Using these bus bars to connect 3 x 12.5kwh solar batteries to my Sunsynk inverter. Easy to install, well made and work great.

### ⭐⭐⭐⭐⭐ Does the job I want it for
*by S***T on 7 September 2025*

Quality product , no problems , would use again

### ⭐⭐⭐⭐ Superb bits of kit but surely overpriced
*by A***R on 24 August 2019*

Solid: these ooze quality and inspire confidence. Good chunky plastic base (with decent quality mounting screws supplied) supports a solidly fashioned bar and impressive terminals, with reassuringly thick sprung washers and nuts. Readily holding the welding cable I was attaching for an off-grid solar setup. I'd have to query the price though, for what they are.
