Solar Photo-voltaic (PV) and Distributed generation (DG) systems convert DC from renewable-energy capture devices (wind/solar) or energy storage devices (battery/fuel-cell) into AC power. Many systems with energy storage are bi-directional allowing AC power to be stored as DC energy until it is needed. Some of these products are able to intentionally island for becoming micro grids or providing critical power (UPS) making AC power available especially in remote locations. Solar PV/DG grid tied inverter testing is necessary as all of these applications must comply with multiple regulatory standards (IEEE/UL/NEC/etc.) in addition to being efficient, reliable, and meeting the product’s performance expectations.

NH Research, Inc. (NHR) provides test equipment for PV/DG grid tied inverter testing (Fig. 1) which can simulate the utility connection as well as energy storage devices. For example, the 9410 Grid-Simulator is used to verify product AC performance while a 9200/9300 Series Test System may be used to emulate any energy storage system. This combination is an ideal solution to verify product performance and ensure compliance with IEEE 1547, UL 1741, and similar grid-tied standards around the globe.

NHR AC & DC Regenerative products deliver the power, precision & flexibility needed to meet or exceed your test solution needs.
