The whole family has NTS-250P/400P, NTS-300/450/750/1200/1700/2200/3200, and NTU-1200/1700/2200/3200 series . The whole family of NTS/NTU are fully digital designed, with three major characteristics of miniaturization, high efficiency, and intelligence. The main features are, instantaneous peak load capacity which can reach up to 2 times of output wattage, as well as AC output voltage/frequency/power saving mode adjustment capability through the DIP switch of front panel (the idle standby consumption is 1.5W) . It’s efficiency reaches up to 93%, and it can be operated within temperature range from -25~+70℃ . Built-in remote control, able to monitor the battery voltage and the load status of the inverter through IRC1/2/3 . Not only intergrated multiple intelligent protections, but also passed safety regulations such as CB/DEKRA/E13/EAC/UL/RCM/FCC/CE/UKCA. Materials and components are strictly selected and 3-year warranty is provided. It is suitable for households, vehicles, yacht and remote areas without power grids. Common application such as, lighting, air conditioning, refrigerators, hair dryers, microwave ovens , computers, televisions, hand-held power tools, motor equipment, mobile AC power... etc.  \nIndex  \n1.

Safety Guidelines  \n􀀂 Risk of electrical shock and energy hazard. All failures should be examined by the qualified technician. Please do not remove the case of the inverter by yourself.  \n􀀂 Please do not install the inverter in places with high moisture or near water.  \n􀀂 Please do not install the inverter in places with high ambient temperature or under direct sunlight.  \n􀀂 Please only connect batteries with the same brand and model number in one battery bank. Using batteries from different manufacturers or different capacity is strictly prohibited!  \n􀀂 Never allow a spark or flame in the vicinity of the batteries because they may ignite explosive gases during normal operation.  \n􀀂 Make sure the air flow from the fan is not obstructed at both sides (front and back) of the inverter. (Please allow at least 15cm of space)  \n􀀂 Please do not stack any object on the inverter.  \n􀀂 Please do not turn on the inverter before start the engine if inverter connected to vehicle's battery directly.  \n􀀂 Branch rated over current protection for the AC output circuit is to be provided at the time of installation.  \n􀀂 Risque de choc électrique et danger d'électrocution. Toutes les pannes doivent être examinées par un technicien qualifié . Veuillez ne pas retirer vous-même leboîtier de l'onduleur.  \n􀀂 N'installez pas l'onduleur dans des endroits très humides ou à proximité d'eau.  \n􀀂 N'installez l'onduleur dans des endroits où la température ambiante est élevée ou sous la lumière directe du soleil.  \n􀀂 Veuillez ne insérer que des batteries de la même marque et du même modèledans un seul banc de batteries.
