Every building is now a power system. We engineer it like one.
Grid, solar, inverter, generator — your building runs four sources. MEPESOL designs and builds the distribution board that makes them hand over safely: engineered, factory-built, tested and warrantied as one product.
ENGINEERING DESIGNEvery circuit drawn before it's built
The group delivers to — including OEMs who compete with us
SHT 01Why now
The utility grid got a second act — inside your walls.
We spent seventeen years engineering protection and control for utilities and OEMs. Buildings now face a smaller version of the same problem — and they are being served far worse.
What changed
Four sources per home
Every new build runs grid, solar, inverter and generator. That is a source-changeover problem — precisely the discipline of switchgear engineering.
What's missing
Boards improvised on site
Residential distribution boards are assembled loose on site from mixed parts. No design, no testing, no warranty — and nobody accountable when it fails.
What we bring
Switchgear discipline
Designed assemblies at building scale: engineered from the room schedule, built and tested before dispatch, documented at handover.
The group already builds panels that protect substations up to 500 kV. MEPESOL builds the same quality of assembly for the buildings people actually live and work in.
SHT 02The offering
Nine offerings on one live wire.
From the first drawing to the commissioning certificate — every stage below is ours, on one circuit, with one party accountable end to end.

09DELIVERY
Installation, testing & commissioning

YOU RECEIVECommissioning certificate
SCOPE
Site survey against as-built conditions
Board mounting, cabling and terminations
Insulation, continuity and polarity tests
Earth-loop impedance and RCD trip times
Changeover proven live across all sources
Test records, warranty and walkthrough
In-house — electrical, end to end
Design & drawings · boards & panels · solar integration · installation · testing & certification. This is our own bench, and it is the core of what we sell.
Coordinated partners
Mechanical, plumbing and architecture are delivered through established partners under our coordination — one team, one programme, one contract, and we say so up front.
SHT 03The board range
The board is the product — and it can see.
From a 5 marla house to a hospital LT panel. Pick a segment and a component tier, then switch on EN-SENSE — a current transformer on every breaker that turns the board into a live energy meter for the whole building.
Standard range
Engineered PROJECT SCALE
Component tier
Energy monitoring
Our standard tier. Breakers and busbar chassis from one certified maker, so the assembly keeps its type-test validity — and the cost advantage shrinks the price premium over loose parts.

03App & desktopYou see consumption per appliance, per floor or per tenant — live draw, monthly cost, and alerts when something starts drawing more than it should.
Standard-range circuit counts are design-engine outputs for representative houses; the 10 marla figure is indicative pending a full room schedule. Engineered segments are sized against the project's own drawings and load study — board count, ratings and essential/non-essential segregation follow the design, not a catalogue page. Breakers are illustrative representations, not manufacturer product photography; brand names denote component tiers only. Send us your drawings for a scoped quotation.
SHT 04The design engine
Room list in. Drawing set out.
Every MEPESOL board starts as data, not as a sketch. A deterministic rules engine — engineering standards as code — turns the plan into schedules, schematics and a priced bill of materials.
AI-ASSISTED
STAGE 1
Read the plan
Room list and source configuration extracted from the architectural drawing. A human confirms before anything is generated.
DETERMINISTIC
STAGE 2
Apply the rules
Circuit schedule, breaker selection, DB sizing, changeover template and list of apparatus — engineering rules as code, not guesswork.
CAD
STAGE 3
Render the drawings
Structured output drives the drawing set: general arrangement, schematics, truth-tables, apparatus list.
LICENSED
STAGE 4
Engineer signs off
The non-standard remainder is flagged for review. A licensed engineer checks and stamps every issued set.
