On-grid system with consumer unit wired to the GRID port
-----------------------------------------------------------------------------------------------------------------------------------------------
In this scenario, there are a few things that need to be considered:
- The CT has been extended less than 10m and is connected as per instructions
- The battery is wired to BMS CAN on the inverter and PCS/CAN on the battery.
- In the event that there are multiple batteries, in addition to the aforementioned point, it will be necessary to connect the OUT port on the master battery to the IN port on the subsequent battery, and so on.
- There is nothing wired to the GEN/AUX or LOAD port.

Battery settings
Battery type: Lithium
Battery capacity: The sum of all the batteries capacity
Charge Amps: 50A if only one, 40A per battery if more than one. Note that each inverter has a different charge rate.
Discharge Amps: 50A if only one, 40A per battery if more than one. Note that each inverter has a different discharge rate.
Shutdown: Needs to match battery DoD
Low Battery: 5% above Shutdown
Activate: Enabled
Restart: 10% above Low Battery
Protocol: 0 (CAN on the inverter screen as well)
Grid Charge: Enabled if you want to charge batteries from the grid at any time
Grid signal: Enabled if using Grid Charge
*Note that GEN settings stand for GENERATOR
System mode
Work mode: Limited to Home (Zero export on the inverter screen)
Solar export: Enabled if want to export excess PV after fully charging the battery/ies or charging them at maximum current
Use timer: Enabled, if not the batteries will automatically charge from grid
Energy pattern: Priority Load
Grid Charge: This will change the meaning of the SOC, if this is selected the battery will charge from the grid from the start of the selected timer to the start of the following one, if not, the battery will be allowed to discharge from the start of the timer to the start of the following one
Timers: Need to be sequential, meaning that the first one MUST be after 0:00 (included) the last one MUST be before 24:00 (not included)
SOC: The % that the batteries will discharge to (if grid charge is not selected during that timer) or the % that the batteries will charge to (if grid charge is selected)
