Section 5: Operation

After all the AC and DC wiring has been installed, you can follow the instructions below to perform the initial startup. First, take a moment to go back over all connections and make sure they are secure and in the proper terminal. If the system utilizes flooded lead-acid type batteries instead of sealed gel- cell type, use the ACS or the DIP switch settings to change the set-up for battery type from gel-cell to flooded lead-acid. If you don’t know which battery type you have, use the gel-cell setting just to be safe, and then contact the battery manufacturer.

1.Verify that the DIP switch settings are correct for your system. See “Section 3: Configuration” if you have the standard control panel, or the ACS Control Panel section if you have that.

2.Check to see that the inverter BYPASS/ON slide switch is in the BYPASS position.

3.Connect the battery cable (or close the battery disconnect switch) to complete the battery circuit. Turn the inverter BYPASS/ON slide switch to the ON position. The System Startup Default is set at the factory at INV OFF/ CHG ON. Press the Inverter ON/OFF switch on the control panel to enable the inverter. When the DC connection is completed, the inverter will begin inverting if there is an AC load and the AC shorepower has not been connected.

4.Place a load on the inverter (plug in a light or other load to an outlet the inverter is powering), and make sure it works. The inverter should run a load without AC shorepower connected (battery only).

5.If the inverter does not come on or go through the start-up, check all connections. Check the inverter’s DC voltage on the positive (+) and negative (–) terminals. If the DC voltage is low or if the battery bank needs to be charged, go directly to Step 6.

6.To charge your batteries, connect shorepower to the inverter by plugging in the shorepower cord and turning on the shorepower breaker. After a few seconds delay, the utility/shorepower LED should light and the Charge LED on the front of the inverter should indicate it is charging. This indicates the charger is working properly. Any AC loads connected to the AC output should also work at this point.

The delay before connecting to the utility AC supply is the inverter sampling the shorepower to see that it is within acceptable frequency and voltage limits. This delay also allows time for a generator to spin up to a stable operating condition before the inverter/charger places a load on it.

7.Disconnect shorepower by turning the shorepower breaker off, or unplugging the shorepower. The inverter should transfer to inverter mode immediately. This will be indicated by a clicking sound as the internal transfer relays change position. The loads should continue to operate uninterrupted.

The preceding steps will complete a functional test of the inverter. If all areas pass, the inverter is ready for use. If any area fails, determine why before proceeding. “Appendix C: Troubleshooting” will help you solve problems you encounter.
