## Customer Reviews

### ⭐⭐⭐⭐⭐ good quality
*by M***S on April 15, 2024*

I used this with my off-grid solar array, and it works great. It arrived quickly and undamaged, installed easily, and so far works flawlessly (over a year so far). A little pricey, but worth it.

### ⭐⭐⭐⭐⭐ Excelente
*by L***S on April 23, 2025*

Excelente producto si estas haciendo algún trabajo eléctrico en casa y lo necesitas.

### ⭐⭐⭐⭐ Works well for solar panel strings.
*by D***C on September 4, 2024*

Works well for solar panel strings. Cannot be used for solar batteries as current flows in different directions on charge vs discharge, so an AC breaker is required.
