Regulation capability
Charge controller is uniquely capable of driving alternator output based on a combination of three primary criteria: voltage, current, and temperature goals / limits – making it possible to configure charging to specific battery manufacturer recommendations.
Voltage: Yes – Via sense wires included in wiring harness.
Current: Yes – Via amp shunt. Can be calibrated to support most shunts. 500A / 50mV is default.
Temperature: Yes – Via alternator and battery temperature sensors. Real-time variable charging output based on ambient alternator and battery temperature.
Battery Temperature and/or current may optionally be supplied via CAN when used with suitable BMS.

Regulator display
Onboard LED: operational and troubleshooting/ fault data via built-in USB connector.
Remote Display: via CAN to remote displays using commonly-accepted marine and RV protocols.
Adaptive idle technology
Allows charge controller to dynamically reduce alternator output to prevent stalling, sluggish performance and match engine power curves at lower RPMs.
White space
Customizable alternator loading vs. RPMs to match available engine power, optimizing alternator output while preventing engine overloading
Zero output technology
Enables charge controller to use current monitoring capability to limit output to match house loads only when batteries are fully charged.
Advanced configuration
Multi-Engine Applications: Allows multiple charge controllers to communicate via the CAN to ensure balanced output and charging efficiency when supporting a single, large battery bank. Device hierarchy establishes master / support relationship between charge sources.

Temperature sensing
Alternator Temperature Sensing: Sensor included in wiring harness. Active regulation based on ambient alternator temperature, ensures optimal output and alternator safety, versus simple capping typical of most voltage dependent regulator models.
Battery Temperature Sensing: Battery temperature monitoring protects the battery from over / under temperature situations, as well as adjust voltage targets based on temperature. Temperature sensor enables the regulator to adjust charging voltage to compensate for changes in battery temperature.
Internal Temperature Sensing: Protects charge controller’s internal circuitry from damage due to out-of-range values.
