• During operation, the heat sink may become hot. Do not touch the heat sink at the sides, or the top of the inverter when in operation
• The inverter is designed to be connected to the grid; connecting your inverter to a generator or other power source can result in damage to the inverter or external devices
• All GivEnergy equipment must be installed by a GivEnergy Approved Installer

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

2. Drill 4 holes at the marked positions, at least 75mm deep. Fix the mounting bracket to the wall using 4 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 sides 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 discoloration of the switch, and that the cables are intact. Please ensure that the top of the inverter is not obstructed in any way. Whilst the inverter is powered down, we recommend operating the PV rotary isolator from ON to OFF 2-3 times, this cleans the contacts of the rotary switch.
Please note: do not carry out this maintenance while the inverter is switched on.

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 5000W (dependent on the inverter model, see table below) 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 the 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 5000W (dependent on the inverter model, see table above). If the load is greater than 5000W the inverter will stop outputting and go into 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 voiding any warranty (see the following diagrams for reference).

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.
2. Generation 1 battery only Check the battery nominal voltage and polarity. When connecting a Gen 1 inverter to a Gen 1 battery (2.6kWh, 5.2kWh, 8.2kWh), a ring terminal to ring terminal cable must be used.
3. Generation 2 battery only When connecting a Gen 1 inverter to a Gen 2 battery (9.5kWh), a ring terminal to an all-in-one cable must be used. Connect the ring terminal cable to the battery terminal 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).
4. Installation of additional batteries If connecting additional Gen 1 batteries after a Gen 2 battery, you must install a DC MCB in between the Gen 2 and the Gen 1 battery to ensure that the Gen 1 battery can be safely isolated, as it has no in-built isolation.

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.

Communication/network ports

Uninstalling the Inverter

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

WORK MODES

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

Peak Charging / Peak Discharging
This is prioritized 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 to support the home, otherwise, the battery can be discharged at full power to support a variable export tariff.

Back-Up / Island Mode
The system has the ability to be used in the event of a power cut. To utilize this feature, circuits must be connected to the inverter’s EPS terminals. To download a fully illustrated guide on connecting the inverter to the EPS, please visit our Knowledge Base at www.givenergy.co.uk.

This inverter is covered by a 12-year warranty.
