  • Page 3 Battery Safety Use only sealed lead-acid, flooded, gel or lithium batteries which must be deep cycle. Explosive battery gases may be present while charging. Be certain there is enough ventilation to release the gases. Be careful when working with large lead acid batteries. Wear eye protection and have fresh water available in case there is contact with the battery acid.

  • Page 5: General Information

    General Information The Rover Series charge controllers are suitable for various off-grid solar applications. It protects the battery from being over-charged by the solar modules and over-discharged by the loads. The controller features a smart tracking algorithm that maximizes the energy from the solar PV module (s) and charge the battery.
  • Page 6 Therefore, assuming 100% efficiency: Power In = Power Out Volts In * Amps In = Volts out * Amps out Although MPPT controllers are not 100% efficient, they are very close at about 92-95% efficient. Therefore, when the user has a solar system whose Vmp is greater than the battery bank voltage, then that potential difference is proportional to the current boost.
  • Page 7 Four Charging Stages The Rover MPPT charge controller has a 4-stage battery charging algorithm for a rapid, efficient, and safe battery charging. They include: Bulk Charge, Boost Charge, Float Charge, and Equalization*. Battery Voltage Constant Charging Bulk Charging Float Charging Equalize Boost Boost...
  • Page 8 The purpose for this is to offset the power consumption while maintaining a full battery storage capacity. In the event that a load drawn from the battery exceeds the charge current, the controller will no longer be able to maintain the battery to a Float set point and the controller will end the float charge stage and refer back to bulk charging.

    RS232 or RS485 port and is used to pair charge controllers with the Renogy DC Home App. After pairing is done you can monitor your system and change parameters directly from you cell phone or tablet. No more wondering how your system is performing, now you can see performance in real time without the need of checking on the controller’s LCD.
