Inverter/Charger Installation Installation Complete Your installation is now complete. The inverter/charger is ready for use. The preceding tests use a light test load (a light bulb) as a test case. If you encounter problems when using a load over 1000 watts (for example, a hair dryer or microwave), see the troubleshooting information in the Conext SW Inverter/ Charger Owner’s Guide.
Installation Multiple Unit Configuration The Conext SW inverter/chargers support multiple unit configuration to increase power output. This gives the system engineer and/or installer more options to work with when tailoring a system to meet load demands. In a multiple unit configuration, only two Conext SW inverter/chargers of the same model can be used.
Multiple Unit Configuration The Input and Output Neutrals are electrically tied at the inverter terminals. Only a Neutral wire (from the AC Out cable) is necessary from each inverter. AC Out Cable AC Out Cable AC In Cable AC Output Breakers AC In Cable AC Input Breakers AC Bypass breakers are not shown. For detailed wiring illustration, see “DualInverter System Renewable Energy (Solar) Wiring” on page 3–8.
Installation DC Connections for Multiple Unit Configuration Individual overcurrent devices are to be used between the battery positive and each positive cable leading to the DC Switchgear. Keep cable lengths to the two DC switchgears the same in order to balance cable losses. Connect the units as follows: 1. Connect the positive cables. Follow the steps in “Connecting the DC Cables to the DC Switchgear” on page 1–25. Also, do not tie the positives in series together between inverters. 2.
Multiple Unit Configuration Configuring the System for Multiple Unit Operation Verify all DC and AC connections. Check Xanbus network connections and ensure that terminators are installed at devices at each end of the network. The simplest system includes a Xanbus SCP, the two multi-unit-configured Conext SW inverter/chargers, and two Xanbus terminators. For both units to operate in multiple unit configuration, a Master and Slave have to be assigned.
Installation Search Mode Operation in Multiple Unit Configuration Search mode is automatically enabled in multiple unit installations with two paralleled Conext SW units. Only the master Conext SW operates, and the slave unit comes online only when the load exceeds approximately 60% of the rated output of the master unit. When the load drops below 20% of the master’s rated output, the slave unit turns off.
Battery Information Battery Information Battery Bank Sizing Battery capacity Battery size or capacity is just as important as the battery type selected for use with the Conext SW. The batteries are the most important part of your system, so it is recommended that you purchase as much battery capacity as possible. A large battery will extend running time and ensure that your inverter/charger delivers full rated surge.
Installation Estimating Battery Requirements Calculating Battery Size Step 1: Compute Amp-hours For each appliance, compute the number of amp-hours that will be used between charging cycles, as follows: 1. Obtain the wattage. If the wattage is marked on the nameplate rating, use that. Otherwise, multiply the marked voltage and amperage: WATTS = VOLTS × AMPS. 2. Obtain the Watt-hours by multiplying that amount by the hours the appliance will be used: WATT-HOURS = WATTS × HOURS. 3.
Battery Information Table 1-4 Battery Sizing Example Daily watt-hours needed for this appliance Appliance (A) Power Consumption (Watts) (B) Operating Time per Day (Hours) (= A × B) TV & VCR 200 W 2 hours 400 Wh Small microwave oven 800 W 15 min = 1/4 hour 200 Wh 3 lamps, 60 W each 180 W 4 hours 720 Wh Coffee maker 600 W 15 min = 1/4 hour 150 Wh Hair dryer 1500 W 6 min = 1/10 hour 150 Wh Total daily watt-hours of AC load 1620 Wh × Number of days between charges 3 = Total watt-hour
Installation Restrictions on Motor Size An appliance may require three to six times its normal running current in order to start. The Conext SW can handle surges up to twice its rated amount (surge current) for five seconds. For example, the model Conext SW 4024 120/240 is rated as having a maximum continuous output current of 15 amps and a surge capability of 32 amps. In motors, the locked rotor amp (also called its starting current) may be specified on the motor nameplate as “LRA” or “LRI”.
Battery Information Battery Cabling and Hook-up Configurations Several smaller batteries can be connected to create a battery bank of substantial size. You can connect batteries in three ways: in parallel, series, or series-parallel. To make a larger battery bank, connect individual batteries with heavy cables. The actual size of the cable depends on whether the batteries are connected in parallel or series.
Installation Battery Series Connection When batteries are connected with the positive terminal of one battery to the negative terminal of the next battery, they are connected in series. In a series configuration, the battery bank has the same Ah rating of a single battery, but an overall voltage equal to the sum of the individual batteries. See below.
