Solar Controllers, Connectors and Wire

Our controllers are designed for charging battery banks. We offer MPPT DuoRacer Dual Output Series and Victron MPPT Controllers.
(*MPPT  = Maximum Power Point Tracking)

MPPT DuoRacer Series Dual Output Marine Controllers:
The DuoRacer marine series solar controllers are the first MPPT controllers designed with dual output. The DuoRacer controller can charge two battery banks simultaneously.  The bulk of solar power is used to charge the primary or main house battery bank (batt1) while a lesser amount of solar power is used to trickle charge the secondary battery bank (batt2) which is typically the start battery.  The battery banks do not have to be of the same battery type so the primary bank can be LiFePO4 batteries and the secondary bank can be AGM or lead acid.  DuoRacer controllers support Sealed, Gel, Flooded, AGM, LiFePO4 and Li-NiCoMn battery types.

Victron MPPT Controllers:
Victron Energy's Top-Rated MPPT Solar ControllersVictron Energy is renowned for its extensive range of high-quality PWM and MPPT solar controllers.

All Victron SmartSolar controllers come equipped with advanced features, including built-in Bluetooth capability. This enables seamless programming and monitoring through multiple devices:
  • Bluetooth Connectivity: Easily program and monitor your solar controller with the free VictronConnect app, available for both Apple and Android devices. The app provides real-time data on your solar system's performance.
  • Optional Remote Display Meter: Enhance your system with the MPPT Control meter, which allows for comprehensive programming and monitoring.
  • Versatile Programming Options: Program your SmartSolar controller using the MPPT Control meter, a Windows 10 PC with an optional USB cable, or directly through Bluetooth on a smartphone or tablet.

Components of a Complete Victron Solar Controller System
For a fully functional solar controller system, consider the following components:
  • SmartSolar Controller: The core of your solar power management.
  • MPPT Control Meter: An optional but highly recommended accessory for enhanced monitoring and programming.
  • VE.Direct Cable: Necessary for connecting your MPPT Control meter to the SmartSolar controller.
  • Smart Battery Sense: If your battery bank is lead acid or AGM and your solar array exceeds 200 watts, this temperature sensor is essential for optimal performance.​
