CUTTING EDGE POWER 8K-12KW Rebel and PowerDock Inverter

ABOUT THIS MANUAL

Purpose
The purpose of this manual is to provide explanations and procedures for installing, operating and troubleshooting for the unit. This manual should be read carefully before installations and operations. Please retain this manual for future reference.

Scope
This document defines the functional requirements of the unit, intended for worldwide use in electronic processing equipment. All manuals are applicable under all operating conditions when installed in the End Use system, unless otherwise stated.

IMPORTANT SAFETY INSTRUCTIONS

WARNING: This chapter contains important safety and operating instructions. Read and keep this User Guide for future reference.

General Precautions

1. Before using the unit, read all instructions and cautionary markings on:

2. The unit (2) the batteries (3) all appropriate sections of this manual.

3. CAUTION –To reduce risk of injury, charge only deep-cycle lead acid type rechargeable batteries lithium or LiFePO4 batteries. Other types of batteries may burst, causing personal injury and damage.

4. Do not expose the unit to rain, snow or liquids of any type. The unit is designed for indoor use only. Protect the unit from splashing if used in vehicle applications.

5. Do not disassemble the unit. Take it to a qualified service center when service or repair is required. Incorrect re-assembly may result in a risk of electric shock or fire.

6. To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or cleaning. Turning off the unit will not reduce this risk.

7. CAUTION –Battery are not already installed by the supplier only a qualified professional (e.g. service person) may install the Inverter.

8. WARNING: WORKING IN VICINITY OF A LEAD ACID BATTERY IS DANGEROUS.
   BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Provide ventilation to outdoors from the battery compartment. The battery enclosure should be designed to prevent accumulation and concentration of hydrogen gas in “pockets” at the top of the compartment. Vent the battery compartment from the highest point. A sloped lid can also be used to direct the flow to the vent opening location.

9. NEVER charge a frozen battery.

10. No terminals or lugs are required for hook-up of the AC wiring. AC wiring must be no less than 10 AWG gauge copper wire details refer to table 2. Battery cables must be rated for 35mm or higher and should be no less than table 1. Crimped and sealed copper ring terminal lugs with a HRNB38-8 hole should be used to connect the battery cables to the DC terminals of the unit. Soldered cable lugs are also acceptable.

11. Be extra cautious when working with metal tools on, or around batteries. The potential exists to drop a tool and short-circuit the batteries or other electrical parts resulting in sparks that could cause an explosion.

12. No AC or DC disconnects are provided as an integral part of this unit. Both AC and DC disconnects must be provided as part of the system installation. See INSTALLATION section of this manual.

13. Fuses are provided as the over current protection of the battery supply.

14. When PV module or panel is exposed to light, it starts to supply high DC voltage, be sure to turn off DC switch before commencing the maintenance, and make sure the cables from PV panel are properly sealed after disconnection.

15. GROUNDING INSTRUCTIONS -This battery charger should be connected to a grounded permanent wiring system. For most installations, the Ground Lug should be bonded to the grounding system at one (and only one point) in the system. All installations should comply with all national and local codes and ordinances.

16. AVOID AC output short-circuit; avoid DC input short-circuit and do not connect the mains while DC input short-circuit

17. Warning: The maintenance information is only for service persons, if the product is used in a manner which is not covered by the scope of warranty, the protection provided by the product may be impaired.

Personal Precautions

1. Someone should be within range of your voice to come to your aid when you work near batteries.
2. If working with lead acid batteries, have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. If working with lead acid batteries, wear complete eye protection and clothing protection. Avoid touching eyes while working near batteries. Wash your hands when done.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eyes, immediately flood eyes with running cool water for at least 15 minutes and get medical attention immediately.
5. Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of the batteries.
6. NEVER smoke or allow a spark or flame in vicinity of a battery or generator.
7. Be extra cautious when working with metal tools on, and around batteries. Potential exists to short-circuit the batteries or other electrical parts which may result in a spark which could cause an explosion.
8. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with battery. Battery can produce short-circuit current high enough to weld a ring, or the like, to metal causing severe burns.
9. If a remote or automatic generator start system is used, disable the automatic starting circuit and/or disconnect the generator from its starting battery while servicing to prevent accidental starting during servicing.
10. The inverter does not provide a neutral/ ground bond internally. This inverter contains an isolation transformer. If required, a neutral / ground bond must be created externally by a licensed professional.

WARNING: Because this inverter is non-isolated, only three types of PV modules are acceptable: single crystalline, poly crystalline with class A-rated and CIGS modules.
To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter. For example, grounded PV modules will cause current leakage to the inverter. When using CIGS modules, please be sure NO grounding.

CAUTION: It’s requested to use PV junction box with surge protection. Otherwise, it will cause damage on inverter when lightning occurs on PV modules.

PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:

1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.

APPENDIX A

How to Select and Configure PV Panels

The following parameters can be found in each PV panel’s specification:

• Pmax: Max output power (W)
• Voc: open-circuit voltage (V)
• Isc: short-circuit current (A)
• Vmp: max power voltage (V)
• Imp: max power current (A)

PV panels can be connected in series or parallel in order to obtain the desired output voltage and current which meets the inverter’s allowed range.

Example 1 – How to connect 48V 8000W model to PV panels with the following parameters?

• Pmax: 260W
• Voc: 37.7V
• Isc: 8.89A
• Vmp: 30.9V
• Imp: 8.42A

1. The max. PV input power for 48V 8000W model is 3500W, 3500W / 260W = 13.46Þmin. 13 PV panels shall be connected.

2. Best Operating Voltage Range is 60~145V, 145V/30.9V = 4.69 Þ max. Number of PV panel in series is 4.

3. Max. input charging current is 60A,60A/8.42A = 7.13 Þ max. Number of PV panel in parallel is 7.

4. Taking (1)~(3) into consideration, the optimized configuration is 3 PV panels in series as a string, and 5 strings in parallel (as shown below).
   Considering the parameters of solar panels, the total power of practical application is about 3500W

5. Check again the Voc and Isc of PV string,

   • Voc of string is 4 x 37.7V = 150.8V < 155V (Max. PV Input Voltage) OK
   • Isc of string is 3 x 8.89A =26.67A < 60A (Max. PV Input Current)  OK
   • Isc of string is 4 x 8.89A =35.56A < 60A (Max. PV Input Current)   OK

DISPOSAL

In the event the product reaches the end of its service life, please contact the local dealer for disposal instructions.The product must not be disposed of with the household waste. Disposal of the product at the end of its service life shall be done in accordance with applicable disposal regulations for electronic waste.
