Pre-Installation photos

Photo of electrical area pre-install (this is where you intend to put the sub board and add any miscallenous items such as henley blocks etc)
Photo of intended location of battery & inverter (See Job Pack as to where that is – and ensure customer is happy with this location)
Photo(s) of of intended DC cable run (take multiple photos and annotate to show the run)
Photo(s) of of intended AC cable run (take multiple photos and annotate to show the run)

Is the number of panels greater than 12?
If number of panels are greater than 12 please LIMIT the inverter to 3.68 upon commissioning

Inverter checklist

Make sure ALL covers are off when commissioning. Apply covers when finished
Are all the DIP switches UP
What generation is the inverter
Use the pre made RJ45 cable supplied by GivEnergy in the inverter box. Plug the RJ45 cable in the BMS port of the inverter. On the other side White is positive and brown is negative
The data cable running between the grid meter and the inverter needs to be wired as such ( make sure the RJ45 is the right way)

On the inverter side (A RJ45 needs to be made here)
Blue - 6
Blue / white - 7

on the grid meter side:
Blue - 10
Blue / white - 9

The CT clamp is wired:
White -1
Black – 2

The arrow should be pointing TOWARDS load
GivEnergy AC charger connections:

Grid Meter:
RS+ Positive goes to 10
RS- Negative goes to 9

CT clamp:
Solid black cable goes to LC-
Black/White goes to LC+

Battery BMS:
Positive goes to BMS+
Negative goes to BMS-
CT clamp directions (If enphase - make sure the Import/Export of the enphase clamp is before the GivEnergy clamps)
Inverter to grid meter:

Meter LC+ (the left port) goes to port 10
Meter LC- (the right port) goes to port 9

Inverter to battery :
AIO orange connection plug
Is their more than 1 battery
Are the batteries 9.5Kwh
Make sure the DIP switches are configured as such
Look at the wiring diagram for adding more than 1 battery. Make sure the data connections go in the correct ports and make sure the DIP switches are configured properly
Does the system use a LoRa device
Inverter side:

Gen 1
RS+ Positive goes to A1
RS- Negative goes to B1

Gen 2
Pin 6 - A1
Pin 7 - B1

Gen 3
Meter LC+ (the left port) goes to port A1
Meter LC- (the right port) goes to port B1

Grid meter side:
Pin 10 - A1
Pin 9 - B1
When connecting the dongle the objective is to make the dongle solid blue(therefore make sure the cover is off). If you are struggling to connect the dongle when following the instructions :

1. Try doing the process on another device
2. Reset the dongle by pressing the black button near the DIP switches
3. Check the customer WIFI to make sure it is dual band and 2.4GHz
