1. Scope of delivery

The manual provides safety guidelines, detailed planning and setup information. It provides

procedures for installing the inverter and information about operation and troubleshooting of the

unit. This manual does not contain details about photovoltaic (PV) panels. Please consult with

system integrator for the information.

2. Important Safety Instructions

SAVE THESE INSTRUCTIONS — this user manual contains important instructions that shall be

followed during the installation and maintenance of the Vertex Solar Inverters.

The following warnings identify conditions or practices that could result in personal injury or loss

of life.

1) Before installing and using the Solar Inverter, read all instructions and cautionary markings

on the inverter and all appropriate sections of this guide.

2) To reduce risk of fire hazard, do not cover or obstruct the inverter.

3) Under some conditions, the surface of Inverter case could be hot enough to cause skin burns

if accidentally touched. Ensure that the Inverter is located away from normal traffic areas.

4) Use only accessories recommended or sold by the installer. Otherwise, not-qualified tool may

result in a risk of fire, electric shock, or injury to persons.

5) To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition

and the wire is not undersized. Do not operate the Inverter with damaged or substandard

wiring.

6) Do not operate the Inverter if it has received a sharp blow, been dropped, or otherwise

damaged in any way. If the Inverter is damaged, call for an RMA (Return Material

Authorization)

7) Do not disassemble the Solar Inverter. It contains no user-serviceable parts. Attempting to

service the Solar Inverter yourself may result in a risk of electrical shock or fire and will void

warranty from manufacturer.

8) Authorized service personnel should reduce the risk of electrical shock by disconnecting both

the AC and DC power from the Inverter before attempting any maintenance or cleaning or

working on any circuits connected to the inverter. Turning off controls will not reduce this

risk. Internal capacitors can remain charged for 5 minutes after disconnecting all sources of

power.

9) Normally grounded conductors may be ungrounded and energized when a ground fault is

indicated.

3. Introduction

Vertex Solar inverter is a off grid PV inverter which consists of three power generation sources

such as PV modules, battery power, and AC power sources. The AC power source could be

generator or utility grid. The configuration is illustrated in Figure 1. When the sun is shining for

PV modules and battery is fully charged, connected loads will be powered by PV modules and

battery. When there is insufficient solar power, the inverter will switch to AC power as major

power source and PV module will charge the battery first.

Figure 1

Working Operations

This device has two working states: no output generation state and output generation state. If

you don’t need to have connected loads powered, you may press ON button of the inverter to

switch to “No output generation” state. If it’s necessary to power connected loads, you may press

OFF button to switch to “Output generation” state. There are four operation modes.

1) Standby mode with PV charging (refer to Figure 2)

Figure 2

The inverter will work in this mode under below conditions:

 When there is no output generation and PV power is available, PV power will charge the

battery and MPPT is functioning at the same time.

 When the inverter is in output generation state with battery voltage below 42Vdc and PV

source is available, the inverter also works in this mode.

2) Standby mode with AC charging (refer to Figure 3)

Figure 3

Page 5 of 20 Rev. A

The inverter will work in this mode when there is no output generation, and PV power source and

PV power source are available.

When the working status change from no output generation to output generation:

 If the battery voltage is higher than 46Vdc, the inverter will switch to inverter mode.

 If the battery voltage is lower than 46Vdc, and AC power source and PV energy are available,

the inverter will switch to bypass mode with PV charging.

 If the battery voltage is lower than 46Vdc with only AC power source available, the inverter

will switch to bypass mode with AC charging.

3) Inverter mode (refer to Figure 4)

Figure 4

When inverter work in this mode. If PV energy is more than required energy for the load, the

inverter will generate power to the connected load and charge the battery simultaneously. If PV

power is insufficient to support connected loads, both PV power and battery will support the load.

If no PV power exists, the inverter will switch to battery independently to support the load. When

the battery voltage drops to 42Vdc, the inverter will switch to bypass mode with PV charging

when PV energy and AC power source are available, or switch to bypass mode with AC charging

while only AC power is available. Or the inverter will switch to standby mode when PV energy and

AC power source are not available. The inverter will go back inverter working mode when the

battery voltage is turning back to 50Vdc.

4) Bypass mode with PV charging (refer to Figure 5)

Figure 5

When inverter work in this mode. AC power source will power connected load and PV energy will

charge the battery in this mode. This operation will be continued until battery voltage is higher

than 50Vdc, and then inverter will automatically transfer to inverter mode.

5) Bypass mode with AC charging (refer to Figure 6)

Figure 6

When inverter work in this mode. AC power source will support the load and charge the battery

at the same time. This operation will be continued until battery voltage is higher than 50Vdc and

then inverter will transfer to inverter mode automatically.

Note: The vertex solar inverter can be setup as a grid-tie solar inverter. Please contact with

supplier for more detailed information.

PV Compatibility

This inverter is designed to generate continuous power from three different power sources: PV

solar modules (solar panels), battery, and AC power source. When MPP input voltage of PV

modules is within 150 VDC to 500 VDC, this inverter is able to generate power to the load or

charge battery. This inverter is compatible with PV module types of single crystalline and poly

crystalline.

Note: When PV input voltage is lower than 250V, the PV input power of inverter will de-rate.

Maximum Power Point Tracking (MPPT)

The Solar Inverter is applied with Maximum Power Point Tracking (MPPT) technology to harvest

the maximum amount of energy from the solar panel.

Measurement must be taken to ensure that the maximum open circuit voltage of 500 VDC is

never exceeded. Please note that the maximum open-circuit voltage will occur at the lowest

temperatures anticipated. You will find more detailed information about temperature

dependency in the data sheet of the PV modules.

Standard Features

The Solar Inverter has the following features:

 Provides comprehensive data with easy-to-read graphic design in LCD display

 Bundled software for remote access inverter data

 Provides RS232/USB communication ports and optional communication cards available

5. Installation

5.1 Installation location

 Do not mount the inverter on flammable construction materials.

 Mount on a solid surface

 High temperature may cause a power reduction due to excessive heating.

 Install this inverter at eye level in order to allow the LCD display to be read at all times.

 Dusty conditions on the unit may impair the performance of this inverter.

5.2 Minimum requirements

 For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the side and

approx. 50 cm above and below the unit.

 For proper operation of this inverter, please use appropriate cables (cable length,

cable cross-section) for grid impedance requirement at the supply terminal.

 The recommended installation position is to be adhered to (vertical).

5.3 Installation

Installation to the wall should be implemented with the proper screws so that the solar inverter

can be easily attached to the wall. After that, the device should be bolted on securely.

Assembly instructions:

 Select an appropriate mounting location. Install the solar inverter in a protected area that is

free of excessive dust and has adequate air flow. Do NOT operate it where the temperature

and humidity is outside the specific limits. (Please check the specs for the limitations.)

 Drill four holes in the marked locations with four screws. (see Fig. 1 & Fig. 2) Place the unit

on the surface and align the mounting holes with four screws.

 Check if the solar inverter is securely fixed.
