Solar BOS accessories

Balance of system: everything in a solar plant other than the panels and the inverter. It is the part nobody photographs and the part that decides how long the plant lasts.

Solar balance of system accessories including mounting rails, MC4 connectors and cable

Where most rooftop problems actually start

Panels and inverters are usually chosen carefully. Structures, cable, connectors and protection are where corners get cut — and where a plant starts failing three monsoons later.

We supply BOS material for our own installations and to customers who are doing their own work and want components that are correctly rated rather than merely available.

What we supply

Rated for outdoor solar use, not general-purpose electrical work.

Module mounting structures

Galvanised structures for RCC, sheet and sloping roofs, designed for the wind conditions of the site.

DC & AC cable

UV-resistant solar DC cable and correctly sized AC cable, cut and terminated on site.

MC4 connectors

Solar-grade connectors, crimped with the right tool rather than twisted and taped.

ACDB & DCDB boxes

Combiner and distribution boxes with the fuses, isolators and enclosure rating the system needs.

SPDs & protection

Surge protection devices, MCBs and isolators selected for the array and inverter rating.

Earthing kits

Earthing electrodes, strips and lightning arrestor arrangements for the plant.

Why rating matters more than brand

  • Cable rated for continuous outdoor UV exposure, not indoor wiring
  • Structures sized for wind loading, not just for holding panels flat
  • Connectors from a single matched system, never mixed makes
  • Protection devices chosen for DC, which does not behave like AC
  • Earthing installed and tested, not assumed

Supplying material only?

Tell us the array size, module make and inverter rating, and we can put together a BOS list that actually matches the plant.
