Page 35: System Configuration
System Configuration Chapter 2, “System Configuration” contains information to help you plan for a Sine Wave Plus installation in an off-grid, on-grid, or backup power application.
Page 36: Pre-Configuration Planning
System Configuration Pre-Configuration Planning Importance Pre-configuration planning is essential to ensure optimal performance for your system. This section outlines the components of a system and how you can plan for them. Types of Applications Sine Wave Plus Inverter/Charger applications: • OFF-GRID (stand-alone) applications where no utility power is available.

Page 38: System Output Requirements
System Configuration Generator Will a generator be used: Voltage Output Requirements (120 Vac only, 120/240 Vac, or 240 Vac only) Auto-Start or Manual-Start Important: the inverter to control the operation of the generator. “Generator Considerations” on page 2–19 Additional What additional equipment is needed: equipment Remote monitors, interface cables, stacking cables, DC charge controllers, auxiliary load controllers, T240 autotransformers etc.
Page 39: Location Considerations
Location Considerations Inverters contain sophisticated electronic components and should be located in a well-protected, dry environment away from sources of fluctuating or extreme temperatures and moisture. The better the environment, the longer the inverter will last. Consider installing your inverter in the same type of location in which you would store high quality electronic equipment of equal value.
Page 40: Mounting Considerations
System Configuration Fire Safety Sine Wave Plus outlined in UL 1741. As such, in the event of a failure, the is designed to fail safe. Be sure the specific mounting and ventilation requirements outlined in this Do not locate the inverter near readily flammable materials such as cloth, paper, straw, plastic etc.
Page 41: Grounding Considerations
Grounding Considerations Types Whether you are installing a new system or integrating new parts into an existing system, the four types of grounding to consider are: • DC system grounding • Inverter grounding • Chassis grounding • Bonding the grounding system Important: All installations must comply with national and local codes and ordinances.
Page 42: Inverter Grounding
System Configuration Inverter Grounding WARNING: Shock Hazard Attach the ground lead BEFORE attaching any AC or DC power connections. Requirement The inverter/charger should be connected to a grounded, permanent wiring system with the AC and DC grounds commonly bonded to each other and should be bonded to the grounding system at only one point in the system.
Page 43: Equipment Or Chassis Grounding
Equipment or Chassis Grounding WARNING: Shock Hazard Attach the ground lead BEFORE attaching AC or DC power connections. Equipment or chassis grounding connects the metallic chassis of the various enclosures together to have them at the same voltage potential, thus reducing the possibility for electric shock. It also provides a path for fault currents to flow through to blow fuses or trip circuit breakers.
Page 44: Bonding The Grounding System
System Configuration wire may be a better grounding electrode than the ground rods. Well casings and water pipes can also be used as grounding electrodes. Under no circumstance should a gas pipe or line be used. Important: Bonding the Grounding System Definition Bonding means connecting one of the current-carrying conductors (usually the AC neutral and DC negative) to the grounding system.
Page 45: Battery Considerations
Generator If the generator is the main source of power, (that is, no utility grid power) then the neutral and ground connections are bonded at the main AC distribution panel. Utility grid If the utility grid is the main source of power, then the bond should be at the utility AC distribution panel.
Page 46: Battery Bank Requirements
System Configuration More information Consult your battery vendor for additional information on battery enclosure requirements. Battery Bank Requirements Note: battery bank is 100 Ah. The recommended battery bank size is determined by the battery bank worksheet in Daily Load in Amp-hours” on page with batteries and should not be operated without them.
Page 47: Figure 2-1 Awg Wire Size Reference Chart
Important Follow the battery cable recommendations listed in this guide. It is recommendation absolutely imperative that you adhere to the battery cable size (wire gauge) and length recommendations provided in this section. If cables are used that are too long or of insufficient gauge (i.e., the diameter is too small), then inverter performance will be adversely affected.
Page 48: Table 2-2 Recommendced Battery Cable Size Versus Length
System Configuration and inverter amperage per NEC/CEC guidelines. It is recommended that the cable has battery acid resistant insulation and is rated for 90 °C (32 °F) or better. Be sure to check with any local regulatory agencies for additional requirements.

Page 52: Wiring Considerations
System Configuration “Installing the Battery Temperature Sensor (BTS)” on page 3–18 instructions on installing the Battery Temperature Sensor. Wiring Considerations Important: grounding and bonding requirements specific to the intended system. All wiring and installation methods should conform to applicable electrical codes and building codes.
Page 53: Generator Considerations
Note: NEC/CEC code. Wire size for AC A minimum of #6 AWG THHN wire is recommended for all AC wiring connections (input and output). Wiring scenarios Determine all wire routes both to and from the inverter and which knockouts are best suited for connecting the AC conduits. Possible routing scenarios include the following.
Page 54: Types Of Generators
System Configuration Stable Voltage The generator should provide a stable voltage and frequency output for the inverter to synchronize with. AC wind turbines and small scale AC water turbines are not recommended for use as AC power sources as they may not be able to provide a stable voltage and frequency as loads and charger requirements change.
Page 55 Manual-start and electric-start generators typically do not have self- protection features to shut down the generator in the event of low oil pressure, over-heating, overcranking, etc., and, therefore, are not designed for unattended starting and operation. If using a manual-start or electric start generator, be sure that the generator is located where it can be easily accessed to be started.
Page 56: Additional/Optional Equipment Considerations
System Configuration “Generator Starting Scenarios” on page 7–23 specific instructions on setting the generator-start/stop conditions. Additional/Optional Equipment Considerations The following components are available for use with the Some of these items may be required depending upon the intended use of the inverter to make the installation code-compliant.

Page 78: Energy Management
System Configuration Energy Management Sine Wave Plus utility power. Advanced features allow for peak load management and time-of-use billing. Utility management features also allow the Plus to use renewable energy sources on a first priority basis and only use utility power if renewable energy is insufficient or unavailable to power the loads.
Page 79: Time-Of-Use (Tou) Metering
Time-of-Use (TOU) Metering Utilities use TOU metering to determine utility charges during peak usage hours and to impose a surcharge. The inverter can be configured to overcome these peak charges by using a battery (or battery bank) to store energy during the inexpensive energy hours and consumes the battery energy during expensive energy hours.
Page 80: Ac Load Support
System Configuration When using the system for TOU metering, the system should be designed with a battery capacity large enough to support the load during the entire peak rate period without reaching the 11C Low Battery Cut Out VDC voltage. To further ensure the batteries are able to support the load, an additional source of power (solar, wind or hydroelectric) is recommended.

Page 264: Theory Of Operation
Inverter Specifications Theory of Operation Sine Wave Plus a combination of three transformers, each with its own low frequency switches, coupled in series and driven by separate interconnected micro- controllers. In essence, it is three inverters linked together by their transformers.
Page 265 The inverter runs in two basic formats: as a stand-alone inverter (converting DC to AC), or as a parallel inverter (with its output synchronized to another AC source). In inverter mode, only 60 Hz waveforms are created. As the battery voltage rises, waveforms with progressively fewer steps are generated.
Page 266: Power Versus Efficiency
Inverter Specifications Power Versus Efficiency There are two primary losses that combine to create the efficiency curve of the the inverter at full output voltage while delivering no current. This is the no load or idle power. At low power levels, the idle power is the largest contributor to efficiency losses.

Page 291: Battery Information
Battery Information Appendix C, “Battery Information” supplies general information about batteries such as battery types, battery bank sizing, battery configurations, and battery care. For detailed information, see your battery manufacturer or your system designer.
Page 292: Introduction
Battery Information Introduction Batteries Batteries are available in different sizes, amp-hour ratings, voltage, liquid or gel, vented or non-vented, chemistries, etc. They are also available for starting applications (such as an automobile starting battery) and deep discharge applications. Recommendations Consider the following recommendations for battery use. •...
Page 293: Sealed Batteries (Gel And Agm
Types of FLA Batteries Industrial (electric forklift) Sealed Batteries (Gel and AGM) Description Gel Cell and absorbed glass mat (AGM) batteries are sealed and do not require the addition of distilled water. Since these batteries are valve regulated, over-charging can cause irreversible damage. Attributes Attributes of sealed batteries are: Types of Sealed Batteries...
Page 294: Understanding Battery Capacity Ratings
Battery Information Other options Another option for 24 volt (only) alkaline battery banks is to use only 19 cells instead of 20. Fewer cells allow the battery charger to operate more closely to the settings used for lead-acid batteries. However, the battery voltage will drop to as low as 18 volts when discharging the batteries.
Page 295: Understanding Amp-Hour Requirements
Depth of discharge In general, the battery bank should be designed so the batteries do not discharge more than 60% of their capacity on a regular basis. Discharging up to 80% is acceptable on a limited basis, such as a prolonged utility outage.
Page 296: Calculating Amp Hours
Battery Information Time and power The length of time a load is operated will affect the power draw. In some cases, an appliance which draws a large wattage may not consume as many amp hours as a load drawing fewer watts but running for a longer period of time.
Page 297: Amp Hour Example Worksheet
Amp Hour Example Worksheet Complete the following steps to calculate the amp-hour requirements per day for your system. Use and own. To calculate amp-hour requirements: 1. Determine the loads the inverter will power and enter their wattage in the watts column. 2.
Page 298: Battery Bank Size Worksheet
Battery Information Battery bank size worksheet Calculation To calculate the battery bank size, use the average amp-hours per day that you calculated using Table C-2 loads. Table C-2 Determining Battery Bank Size Average amp hours per day Divided by inverter efficiency (90%) for Divided by battery efficiency (usually 0.75) Adjusted hours per day Divided by Depth of Discharge (usually 60%)
Page 299: Battery Configurations
Battery Configurations The battery bank must be wired to match the inverter’s DC input voltage specifications (24 or 48 Vdc). In addition, the batteries can be wired to provide additional run time. The various wiring configurations are: Series Wiring batteries in series increases the total bank output voltage. This voltage MUST match the DC requirements of the inverter or inverter and/ or battery damage may occur.
Page 300: Wiring Batteries In Parallel
Battery Information Figure C-2 12-volt Battery Wiring - “Series” Configuration Wiring Batteries in Parallel Effect Wiring the batteries in a parallel configuration increases the current of the battery string. The voltage of the battery bank remains the same as an individual battery.
Page 301: Wiring Batteries In Series-Parallel
Wiring Batteries in Series-Parallel Effect Wiring the batteries in a series-parallel configuration increases the current and voltage of the battery bank. “Series-parallel” wiring is more complicated and care should be taken when wiring these banks. Steps It is done in three steps; wiring the batteries in series, wiring them in parallel, then wiring the string to the inverter.
Page 302: Battery Connections For Stacked Inverters
Battery Information Connect to inverter To connect to the inverter: 1. Connect a cable from the positive terminal of the first battery string to the inverter’s positive DC terminal (via a fused device). 2. Connect the negative terminal of the last battery string to the negative terminal of inverter’s DC terminal.
Page 303: Battery Maintenance
Battery Maintenance Maintenance To get the best performance from an inverter system, the batteries must be strategy properly setup and maintained. This includes setting the proper voltages for Bulk and Float charging. See the “CAUTIONS” in the section on Equalization Charging that follows. In addition, the battery terminals should be inspected, cleaned, and re-torqued if necessary.
Page 304: Table C-4 Variances In Charging Voltage Based On Battery Temperature
Battery Information Table C-4 Variances in Charging Voltage based on Battery Temperature Temperature (around the BTS) Celsiu Temperature compensation is based on battery type—5 mv/cell for lead acid type batteries and 2 mv/cell for alkaline type batteries (NiCad or NiFe). The temperature compensation calculations are derived from Table Table C-5 Temperature Compensation Calculation Battery Type...
Page 305: Equalization Charging
Note: temperatures, the inverter with a BTS may not be able to properly recharge cold batteries due to maximum voltage limits of the inverter. Ensure the batteries are protected from extreme temperatures. Equalization Charging Purpose An equalize charge helps to remove sulfate buildup on the battery plates and balances the charge of individual cells.
Page 306: General Maintenance
Battery Information General Maintenance Water Levels Flooded lead acid batteries require periodic water refills in each battery cell. Only distilled water should be used in a battery, as tap or mineral water may contain contaminants which will upset the battery chemistry and may damage the battery.
Page 307: Table C-6 Battery State-Of-Charge
State of Charge The battery’s state-of-charge should be checked often and only when the battery at a state of rest (when the battery is not powering loads or actively being charged). First thing in the morning is usually the best time to check the state of charge.

Page 309 Generators Appendix D, “Generators” supplies information about generator starting. This information is provided for basic reference only. Because of the wide variety of generator circuits available, Xantrex cannot be held responsible for the accuracy of the information provided. Always refer to the manufacturer’s recommendation for specific operating instructions.
Page 310: Two-Wire Start Circuits
Generators Two-Wire Start Circuits Two-wire starting generators are the easiest to control and are highly recommended for this type of application. A contact closure starts the generator and opening the contacts stops the generator. These types of generators also provide their own cranking control circuit, possibly oil pressure and overtemp protection circuits, and are designed for unattended operation applications.
Page 311: Onan™ 3-Wire Type Generators
Onan™ 3-Wire Type Generators Most Onan 3-wire type generators use a three-position, momentary type switch to control their operation. To start the generator, the switch is held in the “START” position, energizing the ignition system and cranking the starter motor. Once the engine starts, the switch is released and returns to a center off position.

Page 313: E Over-Charge Protection
Over-Charge Protection Appendix E, “Over-Charge Protection” supplies information about options for over-charge protection. This information is provided for basic reference only. Because of the wide variety of over-charge protection available, Xantrex cannot be held responsible for the accuracy of the information provided.
Page 314: Overvoltage Protection Using A Charge Controller
Over-Charge Protection Overvoltage Protection using a Charge Controller When using a renewable energy source to charge the batteries, a charge controller prevents the batteries from exceeding a user-specified voltage level. This preserves and extends the life of the battery by preventing the damage caused by overcharging.
Page 315: Diversion Load Control
Diversion Load Control DC generator devices, such as wind turbines and hydro-electric generators, may be damaged by over-spinning if the DC loads are suddenly removed from them. This can happen if the DC disconnect should open (trip) or the batteries are fully charged and no other DC loads are connected in the system.
