Do not touch the heat sink at the sides, or 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 The inverter must be installed in an easily accessible location, the status display must be visible and not obstructed Please ensure that the wall to be mounted on is sufficient enough to hold the weight of the inverter and battery pack The inverter must be installed in a well ventilated area, the ambient temperature should be below 40ºC to ensure optimal operation The inverter must be installed vertically with connections always positioned at the bottom, never install horizontally, and avoid tilting the unit Do not install in direct sunlight or near water sources Mount the inverter at least 3 feet above ground level (outside only) CONNECTING THE BATTERY TO THE INVERTER 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 The batteries must not be connected in series STEP-BY-STEP INSTALLATION 1. Wall thickness for mounting the inverter must be no less than 120mm. Place the wall mounting bracket 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 rack to the wall using 4 M6x50 expansion bolts. Please note: If fitting inverter to a non-masonry wall, different fixings will be required. 3. Mount the inverter onto the mounting bracket. 4. Insert the 2 Inverter secruirty pins 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. 300mm 250mm 300mm 250mm 250mm 300mm 250mm 300mm 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 cables, and that they are intact. Please ensure that the top of the inverter is not obstructed in any way. Item A B C D E CONNECTIONS OVERVIEW Item Name Battery DC Ring Terminals USB Input EPS Connections AC Connections Battery and Meter communcations D B A C E AC UTILITY GRID CONNECTION Cable size requirements for the AC Coupled Inverter are: AC 3.0 - minimum 2.5mm² 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 seperate AC circuit-breaker per inverter in order to ensure that it is adequately protected and can be safely disconnected under load. AC Supply connection terminals CONNECTING TO THE EPS The Emergency Power Supply (EPS) can provide a maximum output power of 3000W during a grid failure. This output must be protected as close to the inverter as possible, with a double pole 30mA RCD and overload protection 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. Backup connection terminals 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, and adequate overload / short circuit protection is installed in accordance with the IEE wiring regulations. The EPS MAX output power is 3000W. If the load is greater than 3000W 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 any changeover switch to avoid damage to the inverter, and void in warranty (see the following diagrams for reference).

A DC MCB must be installed between the master battery and the inverter (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. 2. Check the battery nominal voltage and polarity. The inverter can be paired with up to 5 of our 51.2VDC domestic battery packs per inverter. The largest capacity battery (master) must be installed closest to the inverter. 3. Connect the positive (red) and negative (black) DC power cables from the DC MCB, ensuring correct polarity. 4. Ensure the AC, DC, and data cable covers are installed tightly against the inverter case, with all 4 screws and no cables are trapped. 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. Ensure that the meter used is approved for use with GivEnergy equipment. The blue CT clamp supplied shall be used to monitor a single source of generation. The CT clamp must be installed around the live supply cable of the inverter, with the arrow pointing back towards the consumer unit. Grid CT Meter 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 battery breaker 3. Turn on the battery 4. The inverter will start automatically when 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. Check the inverter operating status 5. Wait until all LEDs have gone out. The inverter is now shut down 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.

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 orginal 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 optimises the delivery of generated power (if available) and battery power to prioritise the home load. Grid power is used as a last resort if the generation or 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.
