Modular Energy Systems is a sister company to OCON Energy Consulting. We build fully-integrated off grid energy storage system with lithium-ion batteries providing long-lasting energy and high power for air conditioners, pumps, and power tools. It’s plug-n-play design is easy to install, making it ideal for your independent, off grid lifestyle.


Product Design

  • Iterative Design: Host Design Reviews to set a plan to rework and improve the product.
  • Manufacturing/Production Ready Model: Guaranteed to be manufacturable with well defined models and drawings. Parts will include draft for tool release and details for tool parting lines. 
  • Detailed GD&T Drawing: Fully dimensioned manufacturing drawings to meet UL requirements. GD&T dimensioned drawings for tolerance and critical dimensions.
  • Manufacturing Due Diligence: Facilitate DFM from manufacturer.  Assist in tooling design. Manage First Article Inspections and product inspection plan.  Manage quality plan for sustaining production

Solar Engineering

OCON has worked with building departments in over 20 states dealing with high wind zones, high snow loads, and high seismic zones.  We have an in-depth understanding of the ASCE 7-05 and 7-10 building code and are able to provide final building documentation for building department review.
