Full Offgrid inverter for Luna 2000 battery pack

Dear, we are working on it.

Hello, friend.

Only the L1 inverter supports the pure off-grid mode, and only the L1 and M1 inverters are compatible with the LUNA 2000 battery.

Thanks for these informations.
Just two more question, with an 6KTL-L1 with batteries configured in Grid-Tied and Off-grid ESS Mode self consumption:
1/* It seems I need to add one Backup Box and a Smart Power sensor, in case of grid failure to switch the inverter to Off-grid state. What is the use of the box and the Smart Power sensor? Did I need both ? Did you have any information regarding the Backup Box ? Did the smart power sensor need to be installed ? Is the system is working without the Smart power sensor ?
2/* I imagine if they are a grid failure and the inverter change to Off-grid state, the power of the batteries is not injected to the grid ... I imagine this is the use of the Backup Box ...

Hello, friend.

The backup box is used in the household rooftop power station system. The system uses the backup box to switch the inverter status. When the power grid fails, the inverter switches to the off-grid state and supplies power to off-grid loads in backup mode. When the power grid recovers, the inverters are switched to the off-grid state. The inverter switches back to grid-tied mode. For details, see Chapter 1 Product Introduction in the BackupBox-(B0, B1) Quick Guide.

You need to install a DDSU666-H intelligent power sensor for output power management and power limit control. For details about smart meters, see Application Scenarios in the DDSU666-H Smart Power Sensor User Manual.

Hi, thanks for these clear informations.
You told me upper only the L1 provide pure Off-grid mode.
In case of grid connected system with a M1 and Luna Batteries, what happen if we lose the grid (power failure from the grid operator). Is the M1 can switch to Off-grid state (of course using a backup-box B1) ? and come back after on on-grid state ?
Not clear what you means by 'Only the L1 inverter supports the pure off-grid mode'

@Eoxs Hello, my friend.

Yes, when you use M1 and Luna battery and Backup Box, when the grid is down, switch to off-grid state and power the off-grid load through backup mode, when the grid is back up, the inverter cut back to grid-tied operation. What I said only the L1 inverter supports pure off-grid mode. It is because L1 can support off-grid even if there is only LUNA 2000 and no Backup Box, and it is applicable to the specific type of off-grid grid code Island-Grid that supports off-grid mode.
