Tomzn 18-2-2-1000V Solar PV Combiner Box Protection and Configuration
The dual input output configuration consolidates two separate photovoltaic arrays into a single monitored circuit, simplifying system design while maintaining independent branch protection through individual MCB switches. Integrated lightning protection with surge protection devices (SPD) dissipates transient overvoltages before they reach your inverter or battery storage, a critical safeguard in installations exposed to thunderstorm risk. The IP65 waterproof enclosure rating ensures no moisture penetration during heavy rain or washdown cleaning, protecting internal 1000V DC rated components and reducing maintenance downtime. Eighteen DIN-rail mounting positions accommodate fuses, circuit breakers, contactors, and monitoring devices across a single compact box, eliminating the need for multiple separate enclosures. This consolidated approach cuts installation labor while delivering reliable photovoltaic system monitoring and fault isolation that electricians and solar installers depend on.

The seller was not good. To begin with, he gave me an incorrect tracking code for the package. Then, he did not meet the deadlines and exceeded them by more than 15 days. He asked me to wait longer, which I did. The due date arrived, and still no package. I was refunded, but this is my last purchase from your store.

The parcel went on for a long time, the dimensions of the box are too large, for some reason not indicated by the seller. It is better to take the components separately and under them a box
