Closed Loop Communication with POWERSYNC Batteries and Sol-Ark Inverters

Closed Loop Communications: What is that?

POWERSYNC Energy Solutions continues to form solid partnerships with power conversion companies, including Sol-Ark. Through CANBus, the POWERSYNC LiFePO4 Lithium Modular Storage and Sol-Ark 15K, 12K and 8K Hybrid All-In-One inverter systems communicate in a closed-loop state.

In addition to remote reporting of state-of-charge (SOC) and system-level status through Sol-Ark’s web monitoring services, Sol-Ark’s closed-loop communication enables the POWERSYNC battery management system (BMS) to optimize Sol-Ark’s charge parameters to extend battery cycle life and reduce recharge times.

A true system solution can now be offered by solar installers to their customers, demonstrating the potential for advanced lithium energy storage to be used in grid-connected and off-grid applications. By reducing generator use, saving money on diesel fuel, and increasing the useable power from any solar array, we can improve cycle efficiency times by 25% over other lithium batteries of the same capacity.

Sol-Ark’s networked hardware is able to read and react to accurate SOC, historical and real-time status information through the POWERSYNC BMS. The BMS is also capable of taking over and controlling all aspects of charging as needed.

Verified Closed Loop communication creates better remote monitoring and enhanced cycle efficiency.

Accurate state-of-charge (SOC) reporting is a key variable in energy storage system monitoring and maintenance. Not having accurate real-time access to a systems SOC could lead to balance issues along with alarm and protection events with lithium battery management systems (BMS)

Voltage, current and temperature are also communicated to the Sol-Ark inverter to better optimize charging and discharging parameters as well as creating additional safety redundancy.
