Markings on this product

Glossary

AC
Abbreviation for” Alternating Current”

DC
Abbreviation for” Direct Current”

Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt hours). The energy is the power calculated over time. For example, your inverter operates at a constant power of 4600 W for half an hour and then at a constant power of 2300 W for another half an hour, it has fed 3450Wh of energy into the power distribution grid within that hour.

Power
Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an instantaneous value. It displays the power your ARO-US is currently feeding into the power distribution grid.

Power rate
Power rate is the radio of current power feeding into the power distribution grid and the maximum power of the ARO-US that can feed into the power distribution grid.

Power Factor
Power factor is the ratio of true power or watts to apparent power or volt amps. They are identical only when current and voltage are in phase then the power factor is 1.0. The power in an ac circuit is very seldom equal to the direct product of the volts and amperes. In order to find the power of a single phase ac circuit the product of volts and amperes must be multiplied by the power factor.

PV
Abbreviation for photovoltaic.

Wireless communication
The external wireless communication technology is a radio technology that allows the ARO-US and other communication products to communicate with each other. The external wireless communication does not require line of sight between the devices and it is selective purchasing.

Safety

Intended Use
The Growatt ARO6.6-19.8H-C 1-US(Hereinafter referred to as ARO-US) series battery converts the DC current generated by the low-voltage lithium battery module into a high-voltage DC current that meets the requirements of the MIN TL-XH US and performs the work of bidirectional power flow. This series of batteries are manufactured according to all required safety regulations. However, incorrect use may cause fatal hazards to operators or third parties, or may damage equipment and other properties.

NOTE : When connect the ATL battery module to the ARO-US, please make sure that the ATL battery module is turned off,and there is no PV and mains.otherwise there is a risk of electric shock.

Qualification of skilled person
This grid-connected energy storage system can only operate when it is correctly connected to MIN TL-XH US. This connection must be made only by qualified technical personnel, and it must be carried out after obtaining the appropriate approval under the premise that the local authority having jurisdiction requires it.

Safety instruction
The ARO-US is designed and tested according to international safety requirements; however, certain safety precautions must be observed when installing and operating this ARO-US. Read and follow all instructions, cautions and warnings in this installation manual. If questions arise, please contact Growatt’s technical services at +1 (818)800- 9455.

Certified countries

Safety instruction

Selecting the installation location

This is the guidance for installer to choose a suitable installation location, and avoid potential damage to device and operators. Rain-tight or wet location hubs that comply with the requirements in the Standard for Conduit, Tubing, and Cable Fittings, UL 514B, are to be used. The equipment should stand vertically beside the wall. The installation location must be suitable for the weight and size of ARO-US for a long time.

• Select a wall or solid vertical surface that can support the ARO-US.
• Select the installation location so that the status display can be easily viewed.
• Select a well-ventilated location sheltered from direct sunlight and rain.
• Do not install the ARO-US on structures constructed of flammable or thermo-labile materials.
• The humidity of the installation location should be 0~100% without condensation.
• The installation location must be freely and safely accessed at all times.
• When possible, mount the ARO-US vertically. Never install horizontally and avoids forward and sideways tilt.
• Make sure there is a distance of more than 300mm from ARO 6.6-19.8H-C1-US’s front, top, left, and right in order to have better heat dissipation when the machine is running.
• Ensure that the ARO-US is out of the children’s reach.
• Don’t put any physical item on the ARO-US. Do not cover the ARO-US.
• The location shall be away from strong electromagnetic interference.
• Do not install the ARO-US near television antenna or any other antennas and antenna cables.
• Providing better ventilation for the ARO-US to ensure the heat escape adequately.
• The ambient temperature should be below 30°C to ensure optimum operation.
• Do not expose the ARO-US to direct sunlight, as this can cause excessive heating and thus power reduction.
• Observe the Min. clearances to walls, other ARO-US, or objects as shown below:
• There must be sufficient clearance between the individual ARO-US to ensure that the cooling air of the adjacent ARO-US is not taken in.
• If necessary, increase the clearance spaces and make sure there is enough fresh air supply to ensure sufficient cooling of the ARO-US.
• The ARO-US can’t install to solarization, drench, fin location. We suggest that the ARO-US should be installed at the location with some cover or protection.
• Please make sure the ARO-US is installed at the Proper location. The ARO-US can’t install close to trunk.

• The battery pack power terminal faces the right side of the cabinet.

Electrical installations

Intended use
Growatt ARO-US are built according to all required safety rules. Nevertheless, improper use may cause lethal hazards for the operator or third parties, or may result in damage to the units and other property. This unit or system is provided with fixed trip limits and shall not be aggregated above 30 kW on a single Point of Common Connection.

• Convert the low-voltage direct current output from the battery pack into high­voltage direct current. ARO-US can not only release the power of the battery pack but also charge the battery pack.
• Connection system: This ‘interface’ between Utility and inverter may consist of electrical breaker, fuse and connecting terminals. To comply with local safety standards and codes, the connection system should be designed and implemented by a qualified technician.
• Utility: Referred to as ‘grid’ in this manual, is the way your electric power company provides power to your place.

Cable requirements

The maximum allowed wire size for battery cable is 8AWG. The maximum allowed wire size for battery exspansion cable is 5AWG.

Overview of the connection area

DC HV connection area

CAT5/6 standard cables have eight wires (four twisted pairs), as shown in the diagram below. Wire colors may differ from one cable to another. You can use either wiring standard, as long as both sides of the cable have the same pin- out and color-coding.

• Insert the conduit into the right side COM drill guide that was opened
• Insert the CAT 5/6cable through the conduit to the ARO-US wiring box
• Remove the cable’s external insulation using a crimping tool or cable cutter and expose eight wires
• Insert the eight wires into an RJ45 connector, as described in Figure 4
• Use a crimping tool to crimp the connector.
• Connect the signal cable from the battery to the RJ45 port on the communication board.
• Keep the wiring box clean.

Technical Data

Specification

Ambient temperature
The ARO-US can be operated in an ambient temperature from-10-+50°C/14-122°F.The ARO-US US series ARO-US operate at full power and full currents up to a certain temperature, above which they may operate with reduced ratings to prevent device damage. The following diagram illustrates how the output power of the solar ARO-US is reduced automatically in accordance with ambient temperature. The device should be installed in a well- ventilated, cool and dry location. Due to tolerance of temperature sensor and ARO-US efficiency difference under different battery voltage, this derating curve may be a little different from each.
