P902 Customized Inverter is customized.
N840 Limited
output power
Inverter output power and/or current is limited (in practice output current) to a
pre-defined value based on utility and customer requirements. Additional
sticker is attached next to inverter type label that shows the actual limitation
value.
E203 EMC
compatibility
according to
old generic
IEC
standards
and FCC
standards
As standard, the inverter fulfills the new EMC limits set by IEC/EN 61000-6-2
and EN 55011. EN 55011 includes limits also on PV side emissions, the old
EMC standard does not include this. With +E203, the inverter complies with
old EMC standard IEC/EN 61000-6-4 and also FCC CFR 47, Part 15, Subpart
B, Class A (radiated only).
P956 40 °C ratings
(maximum
active current
limited
always to
1866 A)
Inverter current is limited to 1866 A and nominal values are referenced in this
point. This is a variant used in some markets.
