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.

2500KVA Inverter Powerblock Composite

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 auxiliary transformer for specified power systems

PV Unit Substations

Skid Mounted PV Unit Substations

Skid Mounted PV Unit substations provide an all in one integrated solution for utility scale solar Balance of Systems. We design, build, pre-wire, and integrate these units at our facility. All that remains when these units remain on site is to anchor the skid and make outbound field connections. These systems are more compact than our virtual central power blocks and allow for remote field mounted string inverters.

  • 600V and 800V options
  • 1MW up to 3 MW options
  • Typical system includes Medium Voltage Transformer and UL891 Switchboard,
  • Additional options include Auxiliary Transformer, Auxiliary Power Panel, SCADA, Grounding Transformers,
  • Custom cable mounting options available wire termination
  • Skids manufactured using standard c-channel, featuring anti-slip walking surfaces

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
