About BOS

BOS Is the Backbone of Every 25-Year Solar Plant

BOS (Balance of Systems) covers every electrical and mechanical component between your PV modules and the inverter (DC side), and between the inverter and your home or grid (AC side). A well-engineered BOS means a 25-year plant; a bad one means nuisance trips, fire risk and warranty claims.

Arsiga Solar keeps the complete BOS range in ready stock across our 5 North India warehouses — factory-tested, datasheets and BIS/ISI marking for every component.

  • Factory-tested panels with verifiable serial numbers
  • IP-65 polycarbonate enclosures for outdoor use
  • Type-2 SPD for lightning & surge protection
  • BIS / ISI marking on every component
