After all electrical connections to the inverter, batteries, AC source, and sub-panel have beencompleted; follow these steps to test the installation and the inverter operation.CAUTION: Use a multimeter to verify the correct DC voltage for your particular in-verter model (i.e. 48-volt battery bank for a 48-volt inverter) and ensure the polarity ofthe battery voltage is correct (battery positive connected to inverter positive terminaland negative battery connected to inverter negative terminal).2. Apply battery power to the inverter by closing the DC circuit-breaker. The inverter will remainOFF, but the green status indicator on the front of the inverter will quickly blink once to indicatethat DC power has been connected and is ready to be turned on.3. Prior to turning on the inverter, make sure all AC loads (i.e. appliances) are NOT connected tothe inverters output or any AC outlets powered by the inverter.4. Lightly press and release the inverter’s ON/OFF switch to turn the inverter ON. Verify theinverter’s status indicator is blinking - indicating the inverter is ON.5. Connect a ≥ 10 watt light bulb to the inverter output and verify it comes on and shines normally. DONOT connect anything but a light bulb, until all wiring and voltages are confirmed to be correct.Info: The inverter’s AC output voltage will not be correct until a > 5 watt load (5 wattsis default setting) is connected to the inverter; or the search mode is turned OFF witha remote display. The 10 watt or greater light bulb is used because it is a sufficient loadto bring the inverter out of “search” mode up to full voltage.6. Check the AC output voltage of the inverter by connecting an AC voltmeter to the output ter-minals as shown in figure 2-15 and verify the correct output voltages.7. Press and release the inverter’s ON/OFF switch to turn the inverter off. The inverter’s statusindicator and the connected load should go off.8. Apply AC power to the inverter’s AC input. After the AC input power is qualified (approximately15 seconds), the incoming AC power will transfer through the inverter to the inverter’s AC outputand power the light bulb. Verify the inverter’s status indicator and the light bulb comes on.9. Even though the light bulb is on, the inverter is currently disabled (off). Press and release theON/OFF switch on the inverter to enable (turn-on) the inverter.10. Disconnect the incoming AC power to the inverter. Verify the light bulb remains on and is nowis powered by the inverter.If the inverter passes all the steps, the inverter is ready for use. If the inverter fails any of thesteps, refer to the Troubleshooting section.3 03030A C T e rm in a l B lo c kA C O u tp u t120 V A C(+ /- 5% )A C O u tp u t120 V A C(+ /- 5% )A C O u tp u t240 V A C(+ /- 5% )N eu tral to G ro u n d< 0.5V A CFigure 2-15, AC Voltage ChecksInstallation
