From the incoming power supply to the last outlet on the production line, under one technical responsibility.
An industrial facility is not simply one large electrical project. It is a group of designs that must work together: a substation sized for the real load, machine control panels, grounding that protects people and equipment, the SPDA required by standards, and lighting that meets the illuminance level of every area.
When these systems are designed separately, problems surface during construction—and corrections on site always cost more than solving them on paper.
We design the complete system with one engineer accountable for it.
Generating your own energy solves half the problem. The other half is what happens during an outage or during peak tariff hours.
A battery energy storage system stores daytime surplus and supplies it when it matters, while keeping critical processes operating through an interruption. We design the complete arrangement: generation, storage, transfer and the exact loads that remain energized when the grid fails.
Where flammable vapor, combustible dust or gas is present, electrical installations follow different standards and equipment criteria. It is not the same project with extra care; it is a different project.
We classify the area under NBR IEC 60079-10, specify Ex equipment for each zone and issue the documentation required by inspectors and insurers. This is a specialized method that few regional engineering firms provide.

NBR 5410, NBR 14039, NBR 5419, NBR IEC 61439, NBR IEC 60079, NBR ISO/CIE 8995-1, NR-10, NR-12 and NR-18.
Describe what you need through the form or WhatsApp, including size and deadline. Attaching a drawing speeds up the process.
We reply within one business day for a short technical conversation to define scope and verify applicable requirements.
We send a proposal stating inclusions, exclusions, price and schedule.
We deliver with the ART issued.
Every project and technical report issued by Maccari is signed by a qualified professional registered with the appropriate professional council, with an ART or TRT duly filed. You know who is technically accountable before hiring us and after delivery.
The technical team includes electrical engineers, occupational safety engineers and electrotechnical technicians, with consolidated experience in 15, 25 and 35 kV networks.
From survey to commissioning, responsibility is registered in the name of the professional who performed the work.
