Battery System Design Service

Battery Energy Storage System (BESS) Design & Configuration Service

This service is charged on an hourly basis. Please contact us to obtain a total cost estimate for your specific requirements.

This service provides bespoke system design and configuration support for domestic and light-industrial battery energy storage systems. It can be applied to both new installations and upgrades to existing systems, covering a wide range of low-voltage (LV) and high-voltage (HV) battery architectures.

Systems may be grid-connected, off-grid, or hybrid, and can include:

• All-in-one hybrid inverters

• AC-coupled battery systems operating alongside grid-tied inverters

• Modular LV battery stacks

• HV battery strings with dedicated BMS and control units

• Systems based on platforms such as Victron and comparable inverter ecosystems

What’s included

• Review of power requirements, load profiles, and energy usage

• Assessment of solar PV sizing and battery capacity

• Guidance on LV vs HV architecture selection and system topology

• Recommended battery configuration, including series/parallel arrangements where applicable

• Guidance on BMS communication architecture (CAN / RS485 or equivalent)

• Advice on parallel connection limits, current sharing, balancing, and protection considerations

• Recommended inverter-side configuration settings (battery type, charge and discharge limits, control modes)

What you’ll receive

• Clear system architecture and layout diagrams

• Recommended cable sizes, protection devices, and connector pin-outs where relevant

• Step-by-step configuration guidance for control and communications

• A concise written design and configuration summary, suitable for installer handover or future reference

What this service does NOT include

• On-site installation or site visits

• Electrical installation, testing, or commissioning

• Firmware development or modification of batteries, BMS, or inverters

• Responsibility for third-party installer workmanship or regulatory sign-off

Important notes

• LV and HV battery systems vary significantly by manufacturer and inverter platform. This service documents a best-practice engineering approach based on real-world integration experience but does not replace manufacturer documentation, certifications, or warranties.

• Final responsibility for compliance with local electrical regulations, grid codes, and safety standards remains with the installer or system owner.

Required information (requested after purchase)

• Inverter make and model

• Battery type (LV or HV), quantities, and configuration

• Intended communication method (CAN, RS485, or vendor-specific interface)

• Any known constraints, site limitations, or existing system issues
