Renewable Energy & Microgrid Test Solutions
NH Research (NHR) provides power test solutions across the microgrid for testing new power management systems, solar (PV), energy storage systems (ESS), distribued generation (DG), electric vehicles, fast chargers, and the utility grid. NHR’s test solutions include grid-simulators, battery test systems, battery emulators, AC/DC load and sources.
Bi-directional power test solutions are especially ideal for to test the impacts of e-mobility and grid-tied devices (e.g. DG and V2G) on the grid. Simulating the bidirectional power flows to and from the grid substantially speeds up test times and reduces energy costs. NHR’s 9410 AC Regenerative Grid Simulator can verify the AC product performance while NHR’s battery emulators can emulate an energy storage system. The combination of these two products provides an ideal solution for IEEE 1547, UL 1741, and grid-tied standards around the globe. NHR’s AC loads are ideal for simulating any inductive, capacitive, resistive load for testing. NHR’s DC Loads are ideal fast transient and accessory load inrush simulation.
Energy Storage Testing
NHR provides instruments and systems to test batteries, fuel-cells, super capacitors, and similar energy storage devices. Our energy storage test solutions enable scalable power and fast transient speeds for rigorous life-cycle and performance testing as well as energy storage system and battery emulation capabilities.
Solar PV Inverter Testing
NHR provides test instruments for Solar PV inverter testing that can simulate both the utility connection and the energy storage device in accordance to IEEE 1547 and UL 1741.
Wind – DG Inverter Testing
NHR provides inverter test equipment for energy storage and distributed generation that can be part of simulating the utility connection and the energy storage device for IEEE 1547 and UL 1741 testing.
Load Simulation Testing
NHR offers AC/DC products for load simulation and power conversion testing. Our AC Loads are ideal for simulating any inductive, capacitive or resistive load while our DC Loads are ideal for fast transient inrush simulations. The 9430 Regenerative 4 Quadrant AC Load has the capability of simulating almost any linear or non-linear load. Applications include testing of UPSs, AC sources, inverters, rectifiers, switches, circuit breakers and fuses.

Vehicle to Grid Testing (V2G)
Further R&D is taking place to optimize the use of V2G as a form of energy storage capacity to support the utility grid. V2G allows the utility grid to use the EV’s battery during high peaks of energy consumption. NHR’s AC Loads and AC Sources are ideal for testing sophisticated loading profiles and use cases as they allow for bi-direction power flow.
