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 600Vac switchboards. 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.

Engineering Services


Goshen Engineering is a licensed Engineering Services firm with on-staff Professional Engineers. Our engineering process begins with a thorough understanding of your needs through single line diagrams and project specifications. Our typical projects include custom design based on your site requirements. We can provide structural analysis for wind, snow, and seismic loads including Finite Element Analysis and hand calculations.

Our team can utilize existing specifications to integrate with your legacy power system, or we can work together to develop a custom design that meets your project needs. With more than a decade of experience designing, manufacturing and maintaining world-class automation systems, we’re using tried and tested strategies to deliver results.

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

Integrated Power Block

Skid Mounted Central Inverter

Our skid-mounted central inverter solution is a stand-alone, plug and play option that utilizes a compact, rugged design. We offer fully integrated central inverter and medium voltage transformer power blocks. We also offer custom designed skids that can be field integrated. All of our Central Inverter power centers can be custom designed to fit your specific central inverter and MVT options.


UL891 Switchboards

We offer multiple tested designs for solar switchboards. All of our switchboards are designed and tested according to UL891 standards. Our switchboard options include:

  • 800Vac 2500A switchboard standard option up to 13 breakers (35kAic)
  • 800Vac 2500A switchgear compact option up to 8 breakers (35kAic)
  • 600Vac 4000A switchboard with main breaker or main lug only, can include up to 30 feeder breakers (50kAic@600V, 65kAic@480V)
  • 600Vac 3000A switchboard with main breaker or main lug only, can include up to 20 breakers (accepts 250Ato 600A frame breakers) (50kAic@600V, 65kAic@480V)
  • 600Vac 2000A switchboard with or main lug only, can include up to 8 breakers (accepts 250A and 600A frame breakers) (65kAic@600V, 50kAic@480V)
  • 600Vac 1600A switchboard with main breaker or main lug only, can include up to 30 breakers (accepts 250A and 600A frame breakers) (50kAic@600V, 65kAic@480V)
  • 600vac 1200A wall mount switchboard with main breaker and up to (8) feeders, accepts up to 250A feeders, 50kAIC @ 600VAC, 65kAIC @ 480VAC


“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.
