Important Safety Information WARNING Before using your Inverter/Charger, read and save these safety instructions. General precautions 1. Before using the inverter/charger, read all appropriate sections of this guide and any cautionary markings on the inverter and the batteries. 2. Use only a grounded AC extension cord when connecting to AC input power (shorepower). Do not remove or attempt to defeat the ground connection to any shorepower source in any way. 3. If possible, plug the inverte

Important Safety Information 3. Never smoke or allow a spark or flame near the engine or battery. 4. Use caution to reduce the risk of dropping a metal tool on the battery. It could spark or short circuit the battery or other electrical parts and cause an explosion. 5. Remove metal items like rings, bracelets, and watches when working with lead-acid batteries. These batteries produce a short- circuit current high enough to weld a ring, other metal jewellery or tools, thus causing severe burn

Introduction Operating features Inverter/charger The inverter/charger operates as an inverter and as a charger depending upon the operational conditions. When the unit is inverting, it is said to be in invert mode and is referred to as an inverter. When the unit is charging, it is in charge mode and is referred to as a charger. The unit can only operate in charge mode when external AC power referred to as shorepower is connected. Inverter Xantrex HD offers the following inverter features:

Operating features Charger Xantrex HD offers the following charger features: features 50 amp charging, when shorepower is connected, to ensure your truck batteries are always charged Automatic transfer to invert mode When your trucks AC shorepower cord is disconnected, the unit automatically switches to invert mode. When AC shorepower is available again, the inverter automatically switches to charging/pass- through mode. Load management capability which temporarily reduces charging c

Operation Planning for AC loads AC load AC load refers to an AC product you want to operate from the inverter/charger. Loads include most products that you can plug into a standard 120 volt household electrical outlet. Variables The Xantrex HD inverter/charger inverter can power a wide range of affecting AC loads. The size of the load and the length of time you can operate it loads depends on variables such as type of load ambient temperature size, state of charge, temperature, and c

Planning for AC loads DC loads DC loads are those that run off the 12 V electrical system on the truck. A few examples of DC loads are: marker lights, headlights, cab lighting, other lights using DC power DC refrigerators CBs factory-installed radios or sound systems DC loads and the inverter/charger both rely on the batteries for power. Many DC loads running at one time will shorten the operating times of AC loads. Problem loads These are loads you should not operate from inverter/ch

Operation intersection of the time and temperature will indicate approximately the output power of the unit. For example, between 40 °F ( 40 °C) and 77 °F (25 °C), you will get 3000 watts for approximately two minutes or 2500 watts for 3 minutes. 3000 2500 2000 1500 1000 500 0 78 1 2 3 4 5 6 9 10 100 Time (minutes) -40 to 25C 40C 55C 70C 85C 158 F 185 F 40 to 77 F 104 F 131 F Figure 2-1 Output power versus time and temperature Calculating size of an AC load Operating time To determine h

Planning for AC loads Driving the truck while operating AC and DC loads Recharging Driving your truck does not guarantee that the battery is being fully recharged by the alternator if you are running a combination of large AC and DC loads. The alternator must provide more power than the combined DC and AC loads draw for your battery to fully recharge. Example This example shows what happens if the alternator is overloaded. 92 A 1110 W (DC) Xantrex HD AC Loads (1000 W) Alternator 12 Volt Batt
Résumé du contenu de la page N° 20
Operation The efficiency of the inverter/charger is approximately 90%, which means it is drawing about 1100 W (DC) from the battery or 92 amps. This leaves 38 amps for all DC loads. If the DC loads require more than 38 amps, the battery will actually discharge even though the alternator is running. Indication If the alternator is overloaded the: battery voltage gauge on the dashboard begins dropping from approximately 14 V towards 12 V inverter LED signals a low battery with a slow blink
