Precautions

• It is very important for system safety and efficient operation to use appropriate cables for battery connections. 16mm2 (minimum) tri-rated cables must be used for DC battery connections
• The voltage of the battery connected must not exceed 60V (or it will damage the inverter and void any warranty)
• Only GivEnergy batteries should be connected to our inverters
• Reversed polarity will damage the inverter
• The battery must be installed in accordance with the Battery Installation Guide

STEP-BY-STEP INSTALLATION

1. Wall thickness for mounting the inverter must be no less than 100mm. Remove the wall mounting bracket from the back of the inverter and place horizontally onto the wall and mark the position of the bracket holes.

2. Drill 5 holes at the marked positions, at least 75mm deep. Fix the mounting bracket to the wall using 5 x M6x50 expansion bolts.
   Please note: If fitting the inverter to a non-masonry wall, different fixings will be required.

3. Mount the inverter onto the mounting bracket.

4. Insert the 2 x M4 safety locking screws on the left and right side to prevent the inverter from being lifted off the bracket.

CLEARANCE AND MAINTENANCE

Space Clearance
There must be adequate clearance around the inverter to allow for heat dissipation. The diagram below illustrates the space required around the inverter.

Maintenance
When maintaining and cleaning the inverter, the whole system must be powered down. Please refrain from using cleaning products on the surface of the inverter.
To ensure your inverter operates optimally at all times, annual maintenance checks need to be carried out. Check for visible damage or discolouration of the switch, and that the cables are intact. Please ensure that the top of the inverter is not obstructed in any way.
We recommend operating the rotary isolator from ON to OFF 5 times, this cleans the contacts of the rotary switch.

AC UTILITY GRID CONNECTION
Cable size requirements for the Hybrid Inverter are dependent on the model:

• HY 5.0 – minimum 4mm² – 6mm²
• HY 3.6 – minimum 2.5mm² – 4mm²

The recommended maximum cable length should not exceed 50m as the resistance of the cable will consume inverter output power and reduce the inverter efficiency.

You must install a separate AC circuit-breaker per inverter in order to ensure that it is adequately protected and can be safely disconnected under load.

CONNECTING TO THE EPS
The Emergency Power Supply (EPS) can provide a maximum output power of 3600W during a grid failure. This output must be protected as close to the inverter as possible, with a double pole 30mA RCD rated at up to 20A.
There are four approved methods to connect to the EPS, please refer to the EPS Connection Guide on our Knowledge Base for more information.

If the backup terminals are used, please ensure the following:
An earth rod must be installed and connected to the main earthing terminal, as close to the origin of supply as possible, and adequate overload / short circuit protection must be installed in accordance with the IEE wiring regulations.

The EPS MAX output power is 3600W. If the load is greater than 3600W
the inverter will stop outputting and going to fault. The EPS output will only operate when the battery(s) have capacity available.
Any other grid tied generation must be supplied from the grid side of the changeover switch to avoid damage to the inverter, and void in warranty (see the following diagrams for reference).

FULL PROPERTY BACKUP

Correct wiring of full property back-up with manual or automatic change over switch:

Incorrect wiring of full property back-up with manual or automatic change over switch:

CONNECTING THE BATTERY TO THE INVERTER

1. A DC MCB must be installed between the master battery and the inverter of Gen 1 batteries (not less than 100A), this will ensure the inverter can be safely disconnected during maintenance. Please note that a separate DC MCB is not required with Gen 2 batteries as they have one integrated, unless Gen 1 batteries are installed after a Gen 2 battery pack. Generation 1 battery only
2. Check the battery nominal voltage and polarity. When connecting a Gen 3 inverter to a Gen 1 battery (2.6kWh, 5.2kWh, 8.2kWh), an all in one to ring terminal connection must be used. Generation 2 battery only
3. When connecting a Gen 3 inverter to a Gen 2 battery (9.5kWh), an all in one to all in one cable must be used. Connect the all in one plug into the all in one connection on the inverter. The other end can then be connected to the A-socket on the Gen 2 battery (ensure that the red clip is facing away from the inverter, and is pushed in securely). Installation of additional batteries
4. If connecting additional batteries, you will require an all in one to all in one cable (Gen 2 battery), or an all in one to ring terminal cable (Gen 1 battery). There is no requirement for a DC MCB to be installed between additional batteries.

CONNECTING MID APPROVED METER TO INVERTER
In the system, a mid approved meter must be installed to ensure correct monitoring of the grid power. The inverter uses this information to decide whether to charge or discharge the battery.

The CT clamp that is connected to the mid approved meter must be installed around the live incoming supply to the property, with the arrow pointing in the direction of grid import, in order to monitor the complete consumption of the building.

START-UP AND SHUT-DOWN OF THE INVERTER

Start-Up Procedure

1. Connect the AC circuit breaker, ensure that the system is powered and commissioned using the portal/App. Ensure that the grid power is reading identical to that of the mid approved meter (this can be found on the screen of the meter).
2. Turn on the PV switch
3. Turn on the battery breaker
4. Turn on the battery
   The inverter will start automatically when the PV voltage is higher than 150V, and the battery voltage is higher than 46.4V

Shutdown Procedure

1. Turn off the battery
2. Disconnect the AC circuit breaker to prevent it from being reactivated
3. Disconnect the battery breaker to prevent it from being reactivated
4. Turn off the PV switch
5. Check the inverter operating status
6. Wait until all LEDs have gone out. The inverter is now shut down

EARTH BONDING
The bonding kit is to be fixed after the wiring of the inverter.

Earth bonding the Inverter

1. Unscrew the hex screw from the inverter’s bottom cover on the left hand side and remove the screw from the external earthing point
2. Align the bonding plate with the fixing holes on the bottom of the inverter, then fix in place with the M6 x 12 hex screw and serrated washer supplied with the kit
3. Fasten the other end of the bonding plate by reinserting the earthing point screw (please ensure that the serrated washer is secure)
4. Test continuity between earth bonding screw and the supply earth at the AC isolator and record the resistance value (required later for commissioning) . A value around 0.1 ohms is acceptable.
5. Take a photo of the earth bonding kit installed as this needs to be submitted during the commissioning process

COMMISSIONING A SYSTEM
All systems must be commissioned to ensure correct battery and meter communications, as well as connection to the online portal.
Note: Without commissioning, the system may not operate correctly.
Check that all the wires are securely connected before the battery breaker and the AC isolator is switched on. You MUST set the parameters of the battery according to your battery system.

2. Remove all connections and cables from the inverter
3. Remove the locking pins which are securing the inverter to the bracket
4. Lift the inverter off the bracket
5. Remove the wall bracket

Packaging the Inverter
If possible, always pack the inverter in its original packaging and secure it with tension belts. If this is not available, you may also use an equivalent sized box. The box must be capable of being closed completely and be strong enough to support both the weight and the size of the inverter.

Storing the Inverter
Store the inverter in a dry place where ambient temperatures are always between -25ºC and +60ºC

Eco Mode
The system optimises the delivery of generated PV power and battery power to priorities the home load. Grid power is used as a last resort if solar and battery power are unavailable.

Off Peak Charging
This is prioritised to charge the battery during off peak times when energy is cheaper, greener, and cleaner. The battery will start to discharge outside of the off peak time when energy is more expensive.

Back Up / Island Mode
The system has the ability to be used in the event of a power cut. To utilise this feature, circuits must be connected to the inverter’s EPS terminals.
