Who We Serve

Built for projects that need real engineering depth

X10 is not a generic solar installer. We support projects where design, commissioning, controls, diagnostics, and operational reliability actually matter.

  • Developers and owners who need engineering support from concept through commissioning
  • Facilities and campuses deploying solar + storage or resilient backup systems
  • Microgrid operators managing multiple power sources, loads, and monitoring devices
  • Battery storage asset owners needing specialized Megapack and Powerpack expertise
Why X10

Field-proven, controls-savvy, and built for the hard stuff

  • Engineering, commissioning, and monitoring across the full project lifecycle
  • Deep experience with Tesla storage systems, diagnostics, firmware workflows, and custom programming
  • Industrial controls, PLC programming, SCADA integration, and remote monitoring expertise
  • GridBrain platform for hardware-agnostic microgrid visibility, predictive analytics, and automated control
What We Do

Engineering, commissioning, controls, and diagnostics

We help clients design, deploy, validate, and optimize renewable energy systems that have to perform reliably in the real world.

How We Work

From assessment to long-term performance

Whether the need is design, commissioning, diagnostics, or controls, X10 supports the full operating lifecycle of renewable energy systems.

01

Assess

Review the site, system, project constraints, and operational goals to define the right technical path.

02

Engineer

Develop the design, controls strategy, documentation, and implementation plan required for execution.

03

Commission

Validate installation quality, system behavior, integration logic, and performance before handoff.

04

Optimize

Monitor, troubleshoot, and improve long-term system operation through controls, analytics, and diagnostics.
