DC generator installed in a clean white vessel engine room

Projects

The engineering record.

Delivered systems with the documentation to prove it. Full case studies are being cleared for publication with each customer.

DC generator installed in a clean white vessel engine room

Delivered

Marine DC generator, full engineering chain

An autonomous, state-of-charge dispatched marine genset with cloud telemetry: scope, interface control document, control logic, state diagram, fault tree, CAN specification, software requirements, software-in-the-loop testing, and factory test plan, all revision-controlled.

Dual-monitor workstation with code and a CAN trace

Platform capability

The genset CAN protocol standard

One protocol from 14 kW to several hundred kilowatts, with a single master controller implementation across the range. The best proof that Envoltz thinks in platforms.

Containerized battery energy storage system with medium-voltage skid alongside

Delivered

Multi-megawatt mobile BESS at 13.8 kV

The biggest power number in the building, delivered with FMEA, protection coordination, a grounding study, and multi-vendor integration.

Compact DC-link power control enclosure with lid off

Delivered

Frac skid redesign and the DC-link PCU

480 VAC eliminated in favor of an 800 VDC bus, plus a platform-agnostic DC-link control unit on custom firmware.

Bench hardware-in-the-loop rig with controller and instruments

Ongoing program

OEM fleet software program

Versioned firmware with published release notes, field telemetry, and program verification: sustained software ownership of a deployed fleet.

High-current starter battery system with heavy copper busbar

Demonstration

2400 A starter system

A high-current starter system for a multi-thousand-horsepower engine, designed for cold weather to -30 C with self-heating packs. Phase one is a demonstration unit.

Row of finished battery packs on a pallet rack awaiting test

Ongoing program

LTO pack line and serialized fleet lifecycle

Hundreds of serialized packs with per-serial birth-to-refurbishment history: manufacturing scale plus lifecycle service.

Electro-hydraulic drive skid mounted in a truck body

Delivered

Hybrid wireline electro-hydraulic skid

Shipped hardware with schematics maintained under revision control and a published field guide. Delivered and supported.

Vessel engine control room with screens and inverter cabinets

Delivered

Multi-unit marine DC genset integration

International project with master-to-master controller integration alongside a third-party integrator, proving the CAN standard on a second platform.

Variable-speed industrial DC genset trailer at golden hour

In development

1 MW DC generation trailer

The roadmap headline: a megawatt of variable-speed DC generation on one trailer. In development.
