Product Overview

This unit is designed to be wall-mounted. Please ensure the installation is
perpendicular to the floor and the AC plug at the bottom. Do not install the
device on a slanting wall.

To mount the inverter on the wall, please follow the procedure below:

1. Screw the mounting bracket on the wall with 8 M6 Phillips head screws.
Please refer to Figure 3-3.

2. Attach the inverter to the mounting bracket.

3. Use Hex Wrench fixing the inverter with 2 M4 Hexagon Socket screws.
Please refer to Figure 3-4.

3 Installation

- The unit should not be installed in a direct sunlight.

- Servicing of batteries should be performed or supervised by personnel
knowledgeable about batteries and the required precautions.

CAUTION !

WARNING !

- Do not install the unit near or on flammable surfaces.

- Please mount the unit tightly on a solid / smooth surface.

Figure 3-5 : Proper installation gaps

- The bracket supplied with the unit is specially designed and should be the only
mounting device used for the unit.

- It is recommended to install the inverter in a suitable location which offers
non-obscured and safe access, in turn ensuring easy access for service and
maintenance.

- Please install hybrid inverter at an eye level to allow easy observation for operation
and parameter setting.

- Ambient temperature -25° C~60° C. (power de-rating above 40° C)

CAUTION !

17

Installation

• Please use PVC insulated outdoor power cables and connected to the inverter
through a specific certified connector.

• Please use ungrounded PV power system due to E5 does not have galvanic
isolation between the DC-input, Battery and AC-output.

• E5 has array insulation resistance measuring function. Please ensure the
insulation resistance of array is over 550k ohm.

• There are two earth bonding methods for E5.
You can ground the inverter by enclosure grounding hole that shown in Figure 2-4

or by PE terminal of AC plug. Please use at least one grounding method to
avoid electric shock.

• Inverter can support DC inputs in parallel connection (1 MPP tracker) or

separate connection (2 MPP trackers).

• The overview of wiring please refers to Figure 4-1.

4　Wiring

4.1 Preparation Before Wiring

WARNING：SHOCK HAZARD!

- Whenever a PV array is exposed to sunlight, a shock hazard may exist due to
output wires or exposed terminals. To reduce the risk of shock during installation,
cover the array with an opaque (dark) material and ensure that the AC/DC
disconnect switch in the inverter is set to OFF before commencing any wiring.

At first startup, you have to supply AC power and turn on the AC/DC switch.
After a while, LCD display will come live and ask you to set language, country
(electricity regulation), and operation mode.

When all the settings are done, you can see Home Page showing on display.
Now you can supply DC power and wait inverter doing self-test and starting
operation.

In the case of no AC power, you can turn on DC power first then switch on
the AC/DC switch and press the standalone button about 1 second. If DC side
has enough voltage and power, inverter will turn on after a while. In this condition,
inverter is forced operating in standalone mode.

You can also turn on E5 by using battery power. Switch on AC/DC switch and
wake up the battery, waiting about 30 seconds you will see inverter starting
to work in standalone mode. The method of wake up battery will be described
in battery box’s manual.

Turning On the Hybrid Inverter

Hybrid inverter has 6 normal operation modes for users to choose.
Each mode has different behavior between PV, battery, grid, and home load.
The following are the description of these modes.

In some area, the detail behavior of each operation mode may be different due
to the local electricity regulations.

Self-consumption mode is standard hybrid inverter mode.
In this mode, PV power is supplied in following priority :

1. Supply for home load.

2. Charge the battery until it is full.

3. Feed-in the remaining power to grid.

When there is no PV power, battery starts to discharge and supply home load
until it’s empty.
If you had set the time settings, the behavior of hybrid inverter will change.
We will explain it in 5.3.7 Function Setting chapter.

In addition to the 5 modes above, hybrid inverter still have 3 special modes.
These modes cannot be enabled by user but will be enabled automatically by
inverter in some special condition.

Hybrid inverter changes to standalone mode automatically during a power
outage occur. At this time, grid side is disconnected by inverter and home load
are supported by PV and battery power as much as possible.If the battery is
not connected, only when there has sufficient PV power can inverter enter
standalone mode.

Figure 5-28 : Function Settings page

You can assign the lower limit of battery SOC. Battery will stop discharging
when its SOC reach this limit.

• SOC Limit

Peak cut power is used in peak cut mode. You can assign the peak power of
home load usage from grid. When the home load consumption exceeds this
value, battery will discharge to supply remaining power.

• Peak Cut Power

Time settings can be separated into BT charge time and BT discharge time.
Each setting can set 3 time intervals. These 6 time intervals cannot overlap
with each other.
When the inverter operation mode set to self-consumption or selling first mode,
time settings is enabled. Hybrid inverter will automatically change the mode
to charge first / discharge first in the time intervals you set and return to
self-consumption / selling first mode outside the intervals.

• Inverter ID

Inverter will measure the impedance between PV array and PE before
connecting to grid. To avoid risk of electrical shock, it’s not recommending to
disable this function.

• Insulation

Each country has its own electricity regulations. The hybrid inverter can meets
more than one electricity regulations. Installer must select the country correctly.

• Country

Installer can choose the trigger condition of dry contact. The explanations of
these conditions are shown in following table.

This function is currently used in Germany only. Installer in Germany should
set the PV array capacity and enable this function. The maximum feed-in power
to grid will be limited at a percentage of PV array capacity. Installers can set
the various limit percentage to meet the local electricity regulation.

Turning On the Hybrid Inverter

In order to ensure the normal operation of inverter, please check and clean the

unit regularly. Once there are any impaired or loose parts, please contact your

inverter installer.

If the hybrid inverter was damaged and cannot supply the power to home load,

please turn off the AC/DC switch at bottom left and turn on the manual bypass

switch at bottom right to keep the power supply to home load via grid.

Please be noticed that when you turn on the manual bypass switch, grid and

home load are forced connected together. In this case, if grid fault occurred,

inverter will stop supplying any power to grid and home load for avoid electrical

shock of maintainer.

Error message and Trouble Shooting

If it is necessary to put the device out of operation for maintenance or storage,

please follow the procedures below:

At inverter side:

1. Switch off the AC/DC switch and wait for display turning off.

2. Switch the manual bypass switch to normal.

3. Wait for E5’s display panel and battery box’s LED indicator light off.

At wiring side:

4. Switch off AC power line breaker to disconnect from grid.

5. Switch off DC power line breaker to disconnect from PV array.

6.

Use proper voltmeter to check that the AC and DC power are truly disconnected.

7. Remove the AC, DC, and battery wiring.

8. Remove the communication module RS-485 connection from the computer

connection.

Now you may unload the inverter.
