One Point of Responsibility
You work with a single accountable partner instead of managing multiple suppliers. This removes disputes, clarifies responsibilities, and keeps all decisions aligned with your project goals.
We Are Integrator
Volthein – Your Single Point of System Responsibility.
Battery Energy Storage Systems (BESS) are not just technology products — they are complex engineering projects. From grid approvals and system design to procurement, installation, and commissioning, every step must work in perfect alignment. That’s why successful delivery requires a trusted system integrator.
Integrator
We are integrator.
Unlike manufacturers, we’re not limited to a single solution. We provide tailored integrations that truly fit your needs
-
PRECISION EXECUTION
with the right components. The perfect configuration. -
LONG-TERM RELIABILITY & ROI System that works, scales and lasts decade -
ON-TiME & COMPLIANT follow regulations, streamline certification and guarantee smooth approvals from day one. -
PERFORMANCE integration that meets all technical requirements, secures permits and passes certifications effortlessly.
Everything changes
The Power of Integration.
With Volthein as your integrator, you get.
Cost and Risk Reduction
Centralized responsibility reduces scope gaps, unexpected change orders, and overruns. With predictable planning and integrated risk management, projects remain on budget and schedule.
Unified Technical Approach
Civil, electrical, and software disciplines are coordinated under one design framework. This prevents mismatched documentation, ensures compliance, and secures reliable system performance.
Transparent Communication
Clear reporting and single-point communication simplify decision-making. You have constant visibility into project status, milestones, and risks, with no hidden surprises.
Optimized Project Timelines
Parallel planning across permits, procurement, and engineering shortens delivery time. Integration reduces bottlenecks, streamlines approvals, and keeps projects moving without delays.
Reliable Operations Beyond Delivery
Integration continues after handover. Through maintenance, monitoring, and service support, we ensure long-term reliability and keep your system efficient throughout its lifecycle.
Why it Matters
Without an integrator, delivery becomes fragmented.
Multiple vendors, disconnected documentation, regulatory gaps and coordination issues often lead to delays, rework, and increased costs.
1. Permits & Grid Approvals
We manage the permitting process and coordinate with grid operators (DSO/TSO), ensuring compliance with local regulations and securing the required interconnection approvals.
4. Civil & Electrical Works
Execution includes site preparation, foundations, cabling, lightning protection, and all civil and electrical infrastructure necessary for reliable BESS operation.
2. Technical Documentation & Design
Our team prepares full technical documentation, from electrical schematics to control logic. Designs are optimized for safety, compliance, and long-term system performance.
5. Installation & Integration
We assemble, connect, and integrate mechanical, electrical, and digital systems, ensuring that all subsystems work together as a single operational unit.
3. Procurement of Technology Packages
We source and supply key system components, batteries, PCS (inverters), transformers, switchgear, and control systems, exclusively from verified and bankable suppliers.
6. Commissioning & After-Sales Support
The system undergoes full commissioning, grid compliance testing, and performance validation. After handover, we provide technical support, maintenance, and service packages.
