Boost MPPT Solar Charge Controller for High-Voltage Battery Charging in Compact Solar Systems

This boost MPPT solar charge controller is built for charging higher-voltage battery banks from lower-voltage solar arrays, making it suitable for installations where available panel space is limited. It uses Maximum Power Point Tracking to optimise energy harvesting and supports multiple battery chemistries with configurable charging profiles. Integrated system monitoring, electronic protection functions, communication interfaces and optional Bluetooth connectivity support controlled charging and system management across mobile, off-grid and specialised solar applications.

Key Features

  • Boost charging architecture: Allows a lower-voltage solar array to charge a higher-voltage battery bank.
  • Automatic system recognition: Detects supported lead-acid battery system voltage for simplified configuration.
  • Advanced MPPT charging: Tracks the solar array operating point to maximise available charging energy.
  • Multiple battery profiles: Supports AGM, gel, flooded, lithium iron phosphate and user-configurable battery charging.
  • Multi-stage battery management: Uses staged charging to manage battery replenishment and maintenance.
  • System status indication: Integrated LEDs provide operating information and assist with identifying faults.
  • Comprehensive electronic protection: Includes protection against battery and solar polarity faults, overcharging, excessive discharge, short circuits, excessive current and temperature conditions.
  • Remote monitoring ready: Supports an optional Bluetooth module for use with Renogy's monitoring application.
  • System communication: Integrated serial and CAN connectivity supports monitoring and controller integration.
  • Parallel controller support: CAN communication allows compatible controllers to operate together within a system.

The controller combines boost conversion, MPPT regulation and configurable battery charging in a compact enclosure. Its monitoring and protection functions support installation in space-constrained solar charging systems.
