Hello,

I'm about to buy sun2000 10KTL-M1 inverter and reading all documents from web about its fetures and installation methods. I understand that installing a BackupBox B1 together with said inverter I will get an Off-grid load port (backup load) connection.


My question is if I can use that off-grid load port without installing battery? 


Let's suppose the grid fails during daytime but PV panels can generate DC (sunny day). During such an off-grid state can this interver and backup-box together supply power to some dedicated household devices using the off-grid load port without battery installed?


Thanks,

 madimadi

Hello, my friend.
According to your description, when the power grid fails, you cannot connect backup loads without installing energy storage batteries. Solar power itself is extremely unstable. Without storage batteries, the instability of output can lead to the destruction of your equipment.

Hi xiangchenchen,
Thank you for sharing the instability of output power may damage certain equipments. You are obviously right.
Would you confirm, that inverter and backup-box wired properly together and not overloading off-grid backup load (hooked on by low wattage cellar lighting) allows off-grid usage of inverter without battery? Fusion solar will allow grid-tied/off-grid mode switching?

Hello, my friend.
The optical power is unstable. Direct access is easy to burn loads. Therefore, it is not recommended. If lighting is under the cellar, you can directly connect the DC load to the PV module, or connect the inverter output to the AC load. Because the inverter can run off-grid, we do not recommend it.

Hello, my question is if the storage batteries are installed then in a sunny day time will the inverter keep on generating power in the absence of power grid (when the power grid fails).
