[@constantinradoaca8848]

Hi, LUNA2000 can be mounted outside, where there are negative temperatures, -25 degrees Celsius?

Hi, What is the efficiency of the energy optimizer in each 5kWh battery module? Thx a lot!

This is confusing - why does this system need an emergency back-up if it there is a battery installed? I have a grid-tied 12KW Sun2000 inverter, presently without batteries.

@@lne176 Huaweis system is really strange it says battery back up so that battery cant be use when the solar pannels go offline

[@sybalor]

Is it really possible to build 90kW cascade? Can you provide the description how to do it? The official documentation describes 30kW cascade.

[@alfworks]

This is possible but only if you add another 2 inverters which will handle the additional battery packs

Is the "backup box" already certified CEI-021 for Italian Market? If not, when the certification will be available?

[@chikadibiaobi-ofodile540]

Can I get this installed in Scotland? Is you system and battery approved for use in Scotland?
