Battery Diagnostics, UPS & Marine Power Bank Systems
Efficient. Reliable. Built for Harsh Marine Conditions.
Stay Powered – Anywhere at Sea
When you’re operating at sea, a stable and uninterrupted power supply is non-negotiable. Whether it’s for life-saving navigation equipment, automation, communications, or critical control systems – failure is not an option.
At Delta Marine Sweden, we provide advanced diagnostics, equipment delivery, installation, and commissioning of:
- Marine battery systems (Lithium-ion, AGM, Lead-Acid)
- UPS (Uninterruptible Power Supply) units
- Marine-grade power banks and energy storage modules
We support both new builds and retrofit projects – ensuring your energy systems are reliable, efficient, and compliant with international marine standards.
Complete Marine Battery Services
Our approach to energy storage and backup is systematic, scalable, and safety-driven.
Battery Diagnostics & Efficiency Testing (Expanded)
- Measurement of battery charge/discharge efficiency
- Testing for internal resistance, heat buildup, and voltage irregularities
- Full-cycle simulation to determine backup capacity under operational load
- SOH (State of Health) reporting for classification and preventive maintenance
We use calibrated testing tools and generate reports that comply with DNV, BV, and SOLAS audit requirements.
If a system is underperforming or nearing end-of-life, we help you plan a cost-effective and technically sound upgrade path.
UPS Testing, Monitoring & Maintenance
UPS failures are one of the most common causes of system shutdowns at sea.
Delta Marine offers:
- Complete load simulation under emergency conditions
- Switchover timing tests to check response latency
- System firmware verification
- Replacement of failed battery banks or degraded control modules
- Periodic load balancing and maintenance schedules
All diagnostics are conducted under live vessel conditions or dock-side – with minimal disruption to ship operations.
Delivery, Integration & Commissioning (Extended)
From sourcing to installation – we take care of:
- Delivery of certified marine UPS units, lithium batteries, and rack-mount power modules
- System engineering support to design power bank layout and redundancy options
- Installation onboard (HV/LV cabling, environmental protection, grounding)
- Control system integration (with SCADA, BMS, Bridge Systems)
- Full commissioning with test certificates and handover reports
We collaborate with shipyards, naval engineers, and onboard personnel to ensure safe and efficient installation on:
- Engine rooms
- Communication hubs
- Bridge panels
- Emergency zones
System Compatibility & Technologies
We work with all major battery chemistries and UPS architectures, including:
- Lithium-Ion (LiFePO4, NMC)
- Valve-Regulated Lead Acid (VRLA)
- AGM Batteries
- Nickel-Cadmium and Hybrid Systems
Our systems are compatible with:
- Hybrid propulsion systems
- Energy recovery setups
- Diesel generator peak shaving applications
- Solar & wind-assisted installations
We also offer thermal monitoring, remote system diagnostics, and marine BMS (Battery Management System) integration support.
Applications & Use Cases
We provide diagnostics and backup power systems for:
- Commercial vessels (cargo, bulk carriers, tankers)
- Passenger ferries and Ro-Ro ships
- Offshore platforms (oil & gas, wind, research)
- Naval units and government fleet
- Port and drydock installations requiring static power backups
Example Project
We provide full-scope solutions tailored for the maritime environment:
Project Highlight: Baltic Research Ship Retrofit – 2024
Delta Marine was tasked with upgrading the complete battery and UPS system of a research vessel operating in the Baltic.
Key objectives:
- Improve emergency power uptime
- Reduce energy loss from inefficient cells
- Minimise weight and space usage
Our team:
- Replaced 20x old lead-acid units with a compact lithium solution
- Installed a new 12kVA UPS with marine BMS integration
- Reduced physical space used by 42%
- Extended battery backup window from 15 to 35 minutes
Result: successful commissioning, immediate operational gains, and full classification sign-off.
FAQ
Yes – our tools are non-invasive, and our team is trained for live-system testing.
No problem. We’ll assess it onsite and provide a recommendation for continued use, repair, or replacement.
Absolutely. Our engineering team will design a system based on your load profile, operational patterns, and available space.
You’ll receive: test reports, configuration files, maintenance recommendations, and class documentation (if required).
