  • Page 9: Safety

    2 Safety Safety Appropriate usage The NTX is a DC to AC grid-tied utility interactive inverter for use with photovoltaic (PV). In general, the NTX takes power from a DC source (PV modules) and converts it to AC power for the utility grid. This power is delivered first to local loads (household appliance, lights, motor loads, etc.), with any excess power fed to the utility.
