Lenmar Enterprises Modified Sine-Wave Output, Troubleshooting NVC250, Problem / Solution

Warning - When using you N-Verter with the vehicle’s engine turned off, the battery is being drained. Be careful to re-start the engine or otherwise recharge the battery periodically to avoid draining the battery too deeply. The internal “low voltage shut-off” of the N-Verter does not guarantee that the remaining power left in the battery is enough to start the vehicle.

Warning - Hot surface! The N-Verter housing may become uncomfortably warm, reaching 65°C (150°F) under extended high power operation. During operation, keep the N-Verter from materials that may be affected by high temperatures.

Modified Sine-Wave Output

THE OUTPUT OF THE N-VERTER IS NON-SINUSOIDAL. This type of output can typically be incompatible with small battery-operated products such as rechargeable flashlights, some rechargeable shavers, and nightlights that plug directly into an AC receptacle to recharge as well as certain battery chargers for battery packs used with power tools. If you wish to use one of these types of items with the N-Verter, monitor its temperature for the first ten minutes to insure excessive heat is not produced. The production of excessive heat indicates the device is not suitable for use with the N-Verter. The overheating does not occur with most devices which use their own AC adapters. The N-Verter is compatible with most of these chargers and AC adapters.
