Solar Solutions

Goshen Engineering provides custom design-build power solutions for your solar project. We specialize in custom balance of systems designs to meet your specific project specifications. Some of our products include skid-mounted virtual central string inverter power skids that also include switchboards and close-coupled medium voltage transformers (MVT). We also provide a rack mounted option in ½ MW and 1 MW distributed string inverter rack clusters, custom central inverter/MVT skids, and UL 891 800Vac and 600Vacswitchboards. We focus our design and integration efforts to provide our solar EPC customers with a fully integrated plug-and-play field solution. Our systems are mounted, pre-wired, tested, and shipped to minimize field wiring and connections.

We take pride in delivering products and solutions that you can trust. Our solar solutions meet or exceed industry standards in design, construction and innovation. Our team will work with you to design and build a cost-effective and reliable balance of systems for your solar project.

  • Designed by licensed professional engineers
  • Wind, snow, and seismic structural calculations
  • Full design submittals for your project including drawings, calculations, and installation manuals
  • Fully integrated for quick and easy field installation
  • Designed, built, and integrated in the U.S.A.

Virtual Central Power Blocks

Skid Mounted String Inverter Solutions

Goshen Engineering provides a complete line of skid-mounted string inverter virtual central power blocks. These systems include an array of pre-wired string inverters which are fed back through a switchboard close-coupled to a skid mounted medium voltage transformer. These power blocks are prewired, tested, and shipped complete to your job-site to offer easy installation with minimal time on-site. Our systems are designed to accept all major string inverter brands. These systems are portable, self-contained units that offer unmatched flexibility and are available in a variety configurations using half-megawatt increments. Key product features include:

  • 600Vac and 800Vac designs
  • 600Vac systems offered in ½ MW up to 3 MW options
  • Double ended 600Vac options allow up to 5 MW in a single power center
  • 800Vac systems offered in ½ MW up to 3 MW options
  • Double ended 800Vac options allow up to 5 MW in a single power center
  • Skids manufactured using standard c-channel, featuring anti-slip walking surfaces
  • Available battery back-up redundancy
  • Available auxiliary transformer for specified power systems

Distributed Rack Clusters

Rack Mounted String Inverter Systems

Rack-mounted string inverters are flexible and compact. Our rack mounted string inverter power centers are flexible and can be mounted on a concrete pad, a metal skid, or can be attached to driven piles. Rack mounted systems are more compact than skid mounted string inverter power centers. Rack systems are more adaptable to many different site conditions and easily distributed throughout the solar field. Our rack systems include the following features:

  • Designed to accept all major string inverter brands
  • 600Vac and 800Vac options
  • Standard rack systems can handle up to 8 string inverters with up to two switchboards
  • Compact rack systems can mount up 4 string inverters with up to two switchboards

Testimonials

“Jason and his team are experts with designing and assembling custom solutions. If deliverables were not what was expected, as happens with all custom solutions in first iterations, Jason and his team were willing to adapt at a cost for the work to design or install to meet the expectations for the delivery. They were successful in taking an idea for a centralized string inverter and AC collection from inception to full delivery with good collaboration with our teams of engineers and field installers.” – Josh Fausset, Project Engineer, NextEra Energy Resources

“Goshen Engineering has been instrumental in the design and production of an AC combiner cabinet to use with our string inverters. From the UL approval, to special 800V considerations, to detailed shop drawings, they have done a great job with on-time delivery. They have also remained flexible and implemented customized options when required.” – Christina Keller, Project Manager/Engineer, FIMER USA

“Jason and his team at Goshen Engineering have been a fantastic partner for EPEC Solution’s solar business. Their expertise in electrical engineering (switchboard design), mechanical engineering (skid design), and product construction (complete skid integration) has enabled EPEC so provide custom engineered, innovative and cost effective solutions to the solar industry.” – Mark Sauls, EPEC Solutions, Inc.
