These enclosures are rated for inside and outside use. They have applications in hydro and solar PV. They accept standard DIN rail breakers. We also sell 1-pole and 2-pole DC breakers. For example a 4 way enclosure will accept 4 x 1-pole or 2 x 2-pole breakers.

If using them outside make sure cables enter and leave from the underside with suitable cable glands to maintain the IP65 rating.
They can also be used for mounting large bus bars as might be needed in your system. Bus bars are often needed to gang common +/-/earth connections together. On larger off-grid system these bars may need 250, 500 or higher amp ratings.
Note: if wiring your own system in NZ, you can do so for voltages up to 120 VDC (ELV) if you have suitable knowledge and experience. For LV systems (>120 VDC) this is prescribed electrical work and it must be done by a licenced electrician.
