Multi-Brand BESS Integration: One Integrator, Multiple Technologies, One System
Solunar provides multi-brand BESS integration for developers, EPCC contractors, asset owners and commercial clients who need flexibility — connecting batteries, PCS, EMS, inverters, SCADA and grid systems from different providers into one working solution.

What is multi-brand BESS integration?
Multi-brand integration means designing and integrating a BESS project using components from different technology providers, while ensuring the complete system works safely, efficiently and reliably.
The challenge is not buying the equipment — it is making everything communicate, operate and perform as one system. That is exactly where Solunar comes in.
A single project may combine
Real projects rarely use one brand end to end. A BESS may involve:
- Battery from one manufacturer
- PCS from another manufacturer
- EMS from a third-party platform
- Solar inverter from another brand
- SCADA from the client’s existing system
- MV switchgear from a local supplier
- Transformer from a Malaysian manufacturer
- Fire suppression from a specialist contractor
- Monitoring software from another provider

Why multi-brand integration matters
Energy storage is not one-size-fits-all. Flexibility lets clients:
- Choose the best battery for the project
- Optimise cost and performance
- Avoid dependence on a single supplier
- Match equipment to local grid requirements
- Use existing solar or electrical infrastructure
- Improve procurement flexibility
- Reduce project delivery risk
- Support future expansion
- Improve bankability with recognised brands
- Customise the EMS strategy for the business case
The integration risk we manage
Different brands do not automatically work together. Common problems include:
- Battery and PCS mismatch
- EMS cannot read complete battery data
- Solar inverter and BESS not communicating
- Different Modbus or communication mapping
- SCADA integration failure
- Unclear alarm hierarchy
- Grid protection not coordinated
- Poor remote-monitoring visibility
- Responsibility gaps between suppliers
- Warranty disputes between providers
Brands & technologies we can support
Depending on project requirements, Solunar can integrate:
- BYD BESS
- EVE BESS
- GoodWe BESS and inverters
- Utility-scale and C&I PCS
- Third-party EMS
- Solar PV and hybrid inverters
- AC-coupled and DC-coupled systems
- Transformer-based systems
- Containerised and cabinet-based ESS
- Microgrid controllers
- SCADA and monitoring platforms
Multi-brand integration by segment
The brand matters, but the outcome matters more:
For solar developers
Integrate batteries into LSS, CRESS, corporate PPA, solar farms and ESS-farm opportunities.
For EPCC contractors
Battery sizing, PCS selection, EMS strategy, integration drawings and commissioning support.
For funds & asset owners
Optimise cost while managing technology risk, availability, O&M and lifecycle replacement.
For C&I clients
Peak shaving, power expansion, self-consumption, backup and power-quality support.
Frequently Asked Questions
Not when it is engineered properly. Solunar coordinates the battery, PCS and EMS into one monitored system and provides single-point support, regardless of the underlying brands.
We weigh capacity, discharge duration, safety, space, cooling, warranty, bankability, budget, timeline and grid requirements — then recommend and integrate the most suitable platform.
Solar developers, EPCC contractors, infrastructure funds, asset owners, factories, commercial buildings, data centres and utilities that want flexibility, cost optimisation and project-specific design.
