• Product description

  • PWM solar charge controllers connect solar panels directly to the battery being charged and, once the battery reaches a specific terminal voltage, charging is regulated by pulse current limiting. 
  • They are therefore suitable for panels with the same nominal system voltage as the battery; otherwise mismatches in the panel V–A characteristic will waste part of the available power.
  • More sophisticated controllers allow configuration of operating parameters or selection of the battery type, while simple regulators have fixed settings optimized for the most common lead‑acid batteries.
  • The Win300 regulator belongs to the group of PWM solar charge controllers and allows selection of the battery type (Pb AGM, Pb GEL, Pb WET, Pb Calcium, LiFePO4, Li‑Ion, LTO).
  • This defines the corresponding operating parameters. 
  • The Win300-NBT model is additionally equipped with Bluetooth technology for wireless setup from a mobile phone. 
  • These controllers are primarily intended for use in mobile installations, e.g. caravans or boats.
  • Specifications:
  • Battery voltage range for active charging: 9–14V.
  • Battery types: Pb AGM, Pb GEL, Pb WET, Pb Calcium, LiFePO4, Li‑Ion, LTO.
