New Firmware Update for InteliNeo 530 BESS Controller: Smarter and More Flexible Operation

InteliNeo 530 BESS, ComAp’s controller for battery energy storage systems, has been upgraded with firmware version 2.1.0, bringing significant enhancements, especially for multi-BESS sites and simple hybrid set-ups with BESS and a single gen-set. Among the most important features is State of Charge (SOC) Balancing, which coordinates energy distribution across multiple BESS units. The update also makes the system easier to use at rental sites, allowing sites with one BESS and one gen-set to run in parallel even if the gen-set does not have its own synchronisation features—the InteliNeo 530 BESS can handle that automatically. 

State of Charge Energy Equalisation
The new SOC Balancing, also referred to as SOC Energy Equalisation, is a coordinated control function for sites with multiple BESS units. It provides dynamic management of active power distribution across multiple InteliNeo 530 controllers to ensure the SOC of all units converges and remains synchronised during charging and discharging cycles. By balancing the SOC based on nominal capacities and target control limits of all units, the system prevents unequal degradation and ensures no single BESS is overused or underutilised.

Simple hybrid set-ups made easier 
The update also brings greater flexibility through a set of improved functions designed for simple integration at rental sites, specifically for “One gen-set – One BESS” configurations. New functions such as refined Control of BCB Opening, Gen P Optimal Control and Smooth Power Transitions allow the system to run with a gen-set in parallel without the necessity for the gen-set itself to have synchronising capability, benefiting solely from the InteliNeo 530 BESS smart control.

Key advantages of the new InteliNeo 530 BESS release:

• Optimised battery longevity and efficiency – thanks to SOC Balancing, energy is distributed and utilised evenly across multiple BESS units to optimise battery longevity and economic efficiency.
• Stronger built-in safety – thanks to advanced voltage protection ANSI 51C (voltage controlled) and ANSI 51V (voltage restrained), the system detects and reacts to overcurrent issues more reliably.
• Flexible Voltage Ratio Management – users can now set charging limits not only based on SOC percentages but also on the actual voltage of the energy storage system.
• Smarter Load Shedding – during the island operation, the controller can now set the number of load-shedding stages based on sophisticated evaluation of SOC, frequency, and kVA.
• Monitoring for DC-coupled PV - the controller can now read information from DC solar communication devices.

Other key improvements include:

• Gen P Optimal Control – ensures a gen-set works at its most efficient point by adjusting power limits it provides while running in parallel with BESS.
• Evaluation of BESS Cycles – a new algorithm that tracks battery life by counting cycles based on the depth of discharge.
• Switchable ECU CAN Speed - selectable baud rates (250 or 500 kbps) for seamless integration across diverse power conversion (PCS) and battery management (BMS) system hardware.
• Smooth Power Transitions – the system gradually reduces its power output to zero, so the BESS powers down smoothly, without any sudden changes.  

This firmware version 2.1.0 is fully compatible with InteliConfig version 2.62.3.0 (or newer) and its new State Decode function.
