Battery Selection

Match Battery Amp-Hour Capacity to Your Application

Select a battery or system of batteries that will provide your Inverter with proper DC voltage and an adequate amp-hour capacity to power your application. Even though Tripp Lite Inverters are highly efficient at DC-to-AC inversion, their rated output capacities are limited by the total amp-hour capacity of connected batteries plus the output of an alternator when one is used.

				Example
• STEP 1) Determine Total Wattage Required					Tools
Add the wattage ratings of all equipment you will connect to	your
Inverter. Wattage ratings are usually listed in equipment manuals or on		Drill		Orbital Sander		Cordless Tool Charger
nameplates. If your equipment is rated in amps, multiply that number times
AC utility voltage to estimate watts. (Example: a drill requires 1.3 amps.
1.3 amps × 230 volts = 300 watts.)
NOTE: Your Inverter will operate at higher efficiencies at about 75% - 80% of nameplate rating.		300W	+	220W	+	20W	=	540W

300W + 140W + 100W = 540W

• STEP 2) Determine DC Battery Amps Required

Divide the total wattage required (from Step 1, above) by the battery voltage to determine the DC amps required and multiply by 1.2 to account for conversion losses.

• STEP 3) Estimate Battery Amp-Hours Required

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. 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.

1.2 x 540 watts ÷ 12V = 54 DC Amps

Mounting

WARNING! Mount your Inverter 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 recommends that you permanently mount your Inverter in the configuration illustrated below. The Inverter features integral mounting brackets on the front and rear of the unit. The user must supply mounting hardware and is responsible for determining if hardware and mounting surface are adequate to support the weight of the unit.

Using the measurements as shown in the diagram install two user- supplied fasteners 1 , leaving the heads slightly raised. Slide the unit over the fasteners to engage the mounting bracket slots 2 . Tighten fasteners. Install two additional fasteners 3 over the remaining mounting bracket.
