Advanced Solar PCU with CAN Communication & TOD Control

Our latest Solar PCU now integrates CAN communication for intelligent lithium battery
management and a powerful Time-of-Day (TOD) control feature for optimized energy
usage.
1. CAN Communication with Lithium Battery BMS
The Solar PCU seamlessly interfaces with the Battery Management System (BMS) via the
CAN Bus protocol, enabling real-time data exchange for enhanced performance and safety.
It continuously monitors key battery parameters such as:
 State of Charge (SOC)
 State of Health (SOH)
 Battery Temperature
Based on this live data, the system makes intelligent operational decisions including:
Battery full cutoff
Battery low warning & cutoff
Transitioning between solar and mains mode
Solar re-connection based on SOC thresholds
This ensures optimal battery usage, extended battery life, and precise energy control
tailored to lithium chemistry.
2. Time-of-Day (TOD) Energy Management
The TOD feature allows users to define up to three discharge time slots and three charging
block time slots. This enables strategic energy scheduling to align with tariff rates, load
demands, or solar availability.
Each time slot includes:
 Customizable time duration for discharge.
 Customizable time duration for mains charger ON/OFF
 User-defined depth of discharge (DoD)
Battery Protection Override:
If the battery voltage or SOC drops below the user-defined minimum during a discharge
period, the system automatically overrides the TOD schedule and reconnects to the mains.
This ensures the battery is never over-discharged, protecting the system at all times.
