Application scenarios

1.Residential Rooftop Solar

Perfect for single-string home arrays where roof area is limited. The DC 1000V 1 in 1 out combiner box with surge protective device, fuse holders and miniature circuit breakers gives householders safe surge-proof DC collection and a quick way to isolate for cleaning or service.

2.Small-Scale Commercial Rooftop

Built for workshops and offices with a single-string array on each roof facet. The IP66 box slips into tight corners, and its built-in breaker lets electricians isolate the circuit in seconds for inverter swaps or routine maintenance.

3.Off-Grid Cabins & Pumping Stations

A pocket-size guard for remote cabins, livestock pumps and micro-grids. One string in, one string out, 1000 V rated—protects controllers from lightning surges and cable faults, yet flips off with a single toggle when the site is unattended.

4.Telecom Towers & Remote Equipment

Slides easily into battery huts or pole-mount racks to feed 48 V rectifiers from a single high-volt string. SPD absorbs strikes, fuses isolate faults, and the MCB gives tower crews a visible break-point before climbing.

5.Distributed Solar Street Lighting

Mounts unseen behind the panel of stand-alone or grid-tied lamp posts. The 1-string box guards LED drivers from surges, melts faults safely in the fuse, and lets maintenance staff cut power at the pole without returning to the control room.
