• STEP 2: Determine DC Battery Amps Required Divide the total wattage required (from step 1, above) by the battery voltage (12) to determine the DC amps required. • STEP 3: Estimate Battery Amp-Hours Required (for operation unsupported by the alternator) Multiply the DC amps required (from step 2, above) by the number of hours you estimate you will operate your equipment exclusively from battery power before you have to recharge your batteries. Compensate for inefficiency and wiring losses by multiplying this number by 1.2. This will give you a rough estimate of how many amp-hours of battery power (from one or several batteries) you should connect to your Inverter. NOTE: Battery amp-hour ratings are usually given for a 20-hour discharge rate. Actual amp- hour capacities are less when batteries are discharged at faster rates. For example, batteries discharged in 55 minutes provide only 50% of their listed amp-hour ratings, while batteries discharged in 9 minutes provide as little as 30% of their amp-hour ratings. You must allow your batteries to recharge long enough to replace the charge lost during Inverter operation or else you will eventually run down your batteries. NOTE: For Tripp Lite Inverters over 1000 watts used in mobile applications, Tripp Lite recommends you use at least two batteries, if possible, fed by a heavy-duty alternator anytime the vehicle is running. Tripp Lite Inverters will provide adequate power for ordinary usage within limited times without the assistance of your vehicle’s alternator. However, when operating extremely heavy electrical loads at their peak, you may wish to “assist your batteries” by running your vehicle engine faster than normal idling. Example Tools ."

If you choose to mount your Inverter, mount it and wire its DC input BEFORE DC battery connection. Failure to follow these instructions may lead to personal injury and/or damage to the Inverter and connected systems. Tripp Lite Inverters are designed for flat-surface mounting in a variety of vehicular or non-vehicular applications. User must supply mounting hardware and is responsible for determining if the hardware and mounting surface are suitable to support the weight of the Inverter. Contact Tripp Lite if you require further assistance in mounting your Inverter. Vehicular and Non-Vehicular Flat-Surface Mount Install and tighten four user-supplied fasteners through Inverter mounting slots and into a rigid flat surface. Install fasteners as far back in the mounting slots as possible, otherwise the Inverter may slide back and forth if fasteners loosen. Note: Do not mount unit with its front or rear panel facing down (at any angle). Mounting in this manner will block the cooling fans and seriously inhibit the unit’s internal cooling, eventually causing product damage not covered under warranty. FLAT SURFACE Battery Connection Connect your Inverter to your batteries using the following procedures—always loosely twist each pair of cables (one positive and one negative) together: Connect DC Wiring: Connection to Two DC Terminals The PV1800GFCI model includes two DC terminals; the PV3000GFCI model includes four DC terminals (two positive and two negative). For the PV3000GFCI model, it is recommended that both sets of terminals (4 wires) be used for the connection to the battery. Regardless of the model, you must run positive cable(s) through user-supplied UL-listed fuse(s) and fuse block(s) of the proper size: PV1800GFCI—250 amp fuse, PV3000GFCI—500 amp fuse. An excellent source of cables are battery jumper cables. Output performance will decrease if you use only one jumper cable. Connection to Four DC Terminals To obtain maximum output power from the PV3000GFCI model, it is recommended that you connect your battery to all four DC terminals. In this connection you must run 4 wires of equal length between the inverter and the battery. Length & Gauge of Cables Although your Inverter is a high-efficiency converter of electricity, its rated output capacity is limited by the length and gauge of the cabling running from the battery to the unit. Use the shortest length and largest diameter cabling (maximum 00 gauge) to fit your Inverter’s DC Input terminals. Shorter and heavier gauge cabling reduces DC voltage drop and allows for maximum transfer of current. Your Inverter is capable of delivering peak wattage at up to 200% of its rated continuous wattage output instantaneously. Heavier gauge cabling should be used when continuously operating heavy draw equipment under these conditions. Tighten your Inverter and battery terminals to approximately 3.5 Newton-meters (2.58 foot lbs.) of torque to create an efficient connection and to prevent excessive heating at this connection. Insufficient tightening of the terminals could void your warranty. Conn...
