Solar and battery installation work by Flash J Mechatronics Tech

Energy Solutions

Power systems engineered around how you actually use energy.

Solar, LiFePO₄ battery, and inverter systems, assessed, designed, assembled, installed, and supported by engineers. Not shelf-picked. Engineered.

The System

One system, four engineered parts.

We work with the whole chain, not a single box. Every part is selected, sized, and integrated for the others.

Solar generation

Panels sized to your site and sun exposure

LiFePO₄ storage

Battery packs designed and assembled in-house

Inverter conversion

Matched to your loads and programming modes

Your loads

The real equipment the system must carry

The Problem

The problems we engineer against, every day.

Most power problems are not a lack of equipment, they are a lack of engineering. Wrong sizing. Wrong integration. No commissioning. No support after handover.

We start by listening to what actually happens at your site, then we design against the failure, not against a brochure.

01

Unreliable power

Frequent outages force you to plan life around the grid, or around generator runs.

02

Poorly designed systems

Systems sized without measuring your real loads fail under pressure, undervoltage, overload, undersized storage.

03

Existing systems underperforming

A solar, battery, or inverter system that used to work but no longer delivers, or was never commissioned properly.

04

Rising power costs

Generator fuel and grid bills keep climbing, and nobody has measured what you actually consume.

Engineering Approach

We don’t start with a product. We start with the requirement.

Every engagement follows the same engineering sequence, from the first site visit to long after handover.

  1. 01

    Assess

    We study the site, measure the real loads, and understand how and when you use power.

  2. 02

    Design

    The system is designed around actual usage, with a clear, itemised proposal before anything is ordered.

  3. 03

    Assemble

    Where applicable, battery packs are assembled and prepared in-house, LiFePO₄ cells, BMS integration, load testing.

  4. 04

    Install

    Panels, batteries, and inverters are installed by our own technicians and integrated properly.

  5. 05

    Commission

    Every circuit is tested and configured, and you receive a handover walkthrough of how the system works.

  6. 06

    Support

    Maintenance, troubleshooting, and upgrades, we stay with the system after handover.

Signature Capability

LiFePO₄ battery engineering, designed, assembled, and tested in-house.

Most installers fit batteries made by other companies. We design and assemble our own LiFePO₄ packs, sized to your loads, matched to your inverter, and load-tested before they reach your site.

Build Sequence, Lithium Battery Systems

  1. 01

    Design

    A LiFePO₄ battery sized and specified for your loads and inverter.

  2. 02

    Assemble

    Cells configured and packs assembled in-house, with BMS integration.

  3. 03

    Test

    Packs are load-tested before they leave the workshop.

  4. 04

    Integrate

    Installed and wired into the complete system, solar, inverter, and loads.

  5. 05

    Support

    Maintenance, diagnostics, and upgrades for the life of the battery.

Which System Do I Need?

Find your starting point.

Match your situation below. This is honest guidance, the real sizing happens in the assessment, where your actual loads are measured.

01

“I need power from the sun during the day”

A solar system, panels, mounting, and integration designed and installed for your site.

02

“I need backup power at night or during outages”

A battery + inverter combination, storage sized to carry your priority loads through the night.

03

“I already have solar but need more storage”

A battery design, assembly, and integration project, extending what you already have.

04

“My existing system isn't performing correctly”

Troubleshooting, diagnosis, repair, and upgrades, including systems installed by other companies.

05

“I don't know what system I need”

An energy assessment, we measure your loads and recommend what fits, honestly.

Not sure where you fit?

Every project starts with a free energy assessment, no obligation.

Who We Design For

Homes, businesses, and industry.

The engineering is the same, the systems are not. We design for the site, its loads, and the way it operates, whatever its size.

01

Residential

Homes and estates

  • Whole-home hybrid systems and quiet backup
  • Systems that grow with you, panels and storage later
  • Installation planned around your daily life
02

Commercial

Offices, shops, hotels, businesses, and facilities

  • Backup and full systems for business continuity
  • Load engineering across working hours
  • Professional documentation for procurement
03

Industrial

Factories and larger operational environments

  • Power systems engineered to operational loads
  • Earthing, distribution, and integration handled by engineers
  • Systems sized for equipment, not guesses

Engineer-led design and installation across Abuja and Lagos, backed by 13+ years of combined hands-on experience in battery design, solar and inverter systems, and power electronics.

Maintenance & Support

Installation is the start of the relationship, not the end.

Systems degrade when nobody owns them. We stay with the systems we build, and we rescue systems other companies left behind.

  1. Install
  2. Commission
  3. Maintain
  4. Upgrade
  5. Support

What we actually do

  • Troubleshooting and fault diagnosis, including systems installed by other companies
  • Repairs and component replacement
  • Preventive maintenance visits and scheduled plans
  • System upgrades, more panels, more storage, reconfiguration
  • Inverter programming and configuration
  • Battery system maintenance and integration support
