Capabilities
What our teams do on site.
Field services delivered by Tenax engineers in Bangladesh and Myanmar, from installation through to after-sales.
Telecom Power Installation
DC power systems installed, tested and commissioned: rectifiers, DC distribution, and lithium and VRLA battery banks.
LFP After-Sales Support
Health checks, BMS diagnostics and settings, warranty claims and module replacement for installed lithium (LFP) battery systems.
LFP Refurbishment
Testing and refurbishing lithium battery modules so serviceable capacity goes back into the network instead of to scrap.
Rectifier & Controller Repair
Repair of rectifier modules and controllers, in and out of warranty, with technical support for site teams.
Generator Installation & Service
Diesel generator installation, commissioning and scheduled maintenance at telecom and industrial sites.
Solar EPC
Rooftop and hybrid solar with battery storage: survey, design, supply, installation, net-metering application and O&M.
Remote Monitoring (RMS)
RMS installation so site power, fuel and battery status can be watched and acted on remotely.
Fiber Network ITC
Planning, installation, testing and commissioning of short and long-haul fiber networks.
Telecom ITC
BTS and microwave installation, commissioning, dismantling and swap.
Civil Works & Foundations
Tower, generator and shelter foundation design, earthing, fencing and cable trenching.
High-Voltage Systems
HV generators, switchgear, transformers and grid interconnection.
Project Management
A named project manager, an agreed schedule and regular progress reporting from survey to handover.
Rooftop solar, built to the rules.
Every Tenax solar installation follows our own Solar Installation Guideline, written around Bangladesh net-metering rules and the national building code. We are also registered for government e-tendering (e-GP).
- Designed to SREDA Net Energy Metering (NEM-2025) requirements
- Structural and electrical work to BNBC and IEC practice
- Hybrid systems with battery storage for backup and peak shaving
- Current work includes an 88.66 kWp rooftop and a 28.52 kWp hybrid system with 64 kWh storage in Dhaka
What we supply.

Optical Fiber
OTDR, fusion splicers, power meters, optical cable and modules, VFL, patch cords and fiber tool kits.
IT & Datacenter
L2/L3 switches, IP surveillance, IP PBX, racks and cabinets, UPS, precision cooling, raised floor and fire systems.
Passive Equipment
ODF racks, smart PDUs, DCDB panels, SFP modules, alarm sensors and fire-retardant doors.
Towers & Civil
Tower supply and erection, shelters and DG rooms, earthing and fencing materials.
A second life for lead-acid batteries.
A regeneration technology from Japan, recognised by the ITU, that restores capacity in sulfated lead-acid batteries. It saves replacement cost and keeps batteries out of scrap.
- Extends battery life by up to 10 years in normally functioning batteries
- Adds 1–2 years to batteries deteriorated by sulfation
- Batteries at 20–30% remaining capacity can return to 60–90%
- Can be repeated, unlike methods that damage the lead plates
Safety first, on every site.
Work at height
Trained crews, harnesses and rescue planning for tower and rooftop work.
Electrical safety
Isolation and testing before any DC or AC work begins.
Risk assessment
Site hazards reviewed and controls agreed before work starts.
Protective equipment
The right PPE for every task, issued and checked.
