The power is always integrated (both in case of positive imported and negative
exported power) and the total energy meter is certified according to MID. Operating
temperature: from –25 to +55°C/from –13 to +131°F.
B:
Only the total positive energy meter is certified according to MID. Operating
temperature: from –25 to +55°C/from –13 to +131°F.
A70: The power is always integrated (both in case of positive imported and negative
exported power) and the total energy meter is certified according to MID. Operating
temperature: from –25 to +70°C/from –13 to +158°F.
B70: Only the total positive energy meter is certified according to MID. Operating
temperature: from –25 to +70°C/from –13 to +158°F.
