Important Safety Warning

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:

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

2. CAUTION --To reduce risk of injury, charge only deep-cycle lead acid type

rechargeable batteries. Other types of batteries may burst, causing personal

injury and damage.

3. 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.

4. Do not disassemble the unit. The maintenance information is only for

service technicians. When service or repair is required, contact your

supplier for further arrangements. Incorrect re-assembly may result in a

risk of electric shock or fire.

5. To reduce risk of electric shock, disconnect all wirings (AC mains, batteries,

solar panel) before attempting any maintenance or cleaning. Turning off the

unit might not eliminate the risk.

6. 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 and rated for 75oC or

higher.(Refer to equivalence table on page 10). Battery cables must be rated

for 75oC or higher and should follow the recommendation in the manual.

Crimped and sealed copper ring terminal lugs (refer to INSTALLATION

section) should be used to connect the battery cables to the DC terminals of

the unit. Soldered cable lugs are also acceptable.

7. Be cautious when working with metal tools on, or around batteries. Dropping

a tool and short-circuit the batteries or other electrical parts may result in

sparks and explosion.

8. 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.

9. No over current protection for the battery supply is provided as an integral part

of this unit. Over current protection of the battery cables must be provided as

part of the system installation. See INSTALLATION section of this manual.

10. 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.

11. The unit must be installed and maintained by qualified staff. Please read the

manual carefully before installations & operations.

12. The unit contains energy source: the batteries and solar. All terminals

and

sockets may be powered even when the unit is not connected to the mains.

1. Overview

This is a pure sine wave stand-alone inverter/charger system combining the

function of inverter, solar charger and AC charger, and provides a l

ong

run-time uninterruptible power supply. Its comprehensive LCD display

provides system status, and allows users to set output source priority, charger

source priority, charger current and so on.

1.1 Key Feature

• High-frequency switching technology for compact size and light weight

• Pure sine wave output for wide range of applications and harsh

environment

• Build-in solar charger controller with MPPT technology to optimize the

power utilization

• High efficient DC-to-AC conversion minimizing energy loss

• Standby Charging Mode enables battery charging even when the unit is

switched off

• Intelligent cooling fan control

• Input/output isolated design for the maximum operation safety

• LCD displays comprehensive operation status

• Configurable output source priority, charger source priority, charger

current and so on.

• Supports Home Appliances / Office Equipment/ Lighting Equipment/

Motor-based Equipment (such as Fan, Air-Conditioner, Washing

Machines)

• Thorough protections: Input low voltage / Overload / Short circuit / Low

battery alarm / Input over voltage / Over temperature/SCC over current

protection

• Rack design & wall-mounted design for flexible installation

1.3 Basic System Architecture

A typical application diagram for home and office applications is as shown below.

The inverter supports the following power sources as input:

• Generator or AC utility

• PV modules(optional)

• Batteries

And the inverter is capable of supplying various loads such as fluorescent lamp,

fan, TV, refrigerator, air conditioner and so on.

2. INSTALLATION

2.1 Unpacking and Inspection

The product package is shipped with the following items. Please call your

supplier or dealer if any items are missing.

! 1 X Inverter

! 1 X DC red cable

! 1 X DC black cable

! 1 X User’s manual

2.2 Remove bottom cover

Please take off bottom cover by removing

below 2 screws before connecting wires.

2.3 Placement

Choosing a location to install, the place should be a firm wall and a well-ventilated

room protected against rain, vapor, moisture and dust. The location should provide

adequate air flow around the Inverter with 30cm minimum clearance on all sides

for proper ventilation.

30cm

Use screws to mount the inverter to a solid surface. The recommended screw size

is M4*50~65mm.

2.4 Battery Connection

CAUTION: For safety operation and regulation compliance, it is requested to

install a separate DC over-current protector or disconnect device between battery

and inverter. Note that some installation requirements may not require a

disconnect device, however, an over-current protection installed is still required.

Please refer to typical amperage in below table as required fuse or breaker size.

WARNING! All wiring must be performed by a

qualified technician

WARNING! Check the polarity before connecting the battery

wires

in order not to damage the inverter.

Please follow below steps to connect the batteries:

Step 1 - Install a DC Circuit Breaker for positive (+) battery cable. The rating of the

DC Circuit Breaker must be at least

140Amp for POWERBACK PB3000S,

120Amp for POWERBACK PB5000S to

guarantee safe operation without

interruption. Keep the DC Circuit

Breaker off.

Step 2 - Connect a red cable to BAT+

terminal, and a black cable to BAT -

terminal of the inverter.

Knock off below “BAT+” and “BAT-” holes, cross red cable via “BAT+” hole and

cross black cable via “BAT-“ hole.

Step 3 - Connect the above mentioned red cable to the battery’s positive (+)

terminal and black cable to battery’s negative (-) terminal.

Step 4 - After AC input and output wires are connected, switch on the DC Circuit

Breaker.

Note: Make sure the battery voltage meets the inverter’s specification:

POWERBACK PB3000S supports 24VDC battery system; POWERBACK

PB5000S supports 48VDC battery system. And use at least 200Ah capacity

battery for POWERBACK PB3000S & POWERBACK PB5000S.

2.5 AC Connection

CAUTION: Please install a separate AC breaker between inverter and AC input

power source. This will ensure the inverter can be securely disconnected during

maintenance and fully protected from over current of AC input. The recommended

spec of AC breaker 30A for POWERBACK PB3000S model, 40A for

POWERBACK PB5000S model. Be sure that AC source is switched off before

installing the circuit breaker.

CAUTION: Since the inverter doesn’t have an automatic protection device against back feed current. We recommends installing an external AC contactor (see the diagram below). A warning label shall be attached on such AC contractor to remind the user to disconnect the inverter before accessing the circuit. The rated voltage and current of the AC contactor shall be no less than the inverter’s rated voltage and current, and a minimum 1.6mm space clearance shall be reserved. A circuit breaker shall be installed between AC mains and the inverter in order to disconnect the AC mains when needed. Surge protection is built in. For further protection however, we recommend installing a Sollatek DSP and Sollatek AVS. Contact us for further information.
