* Load curve :

The relation of input DC voltage and output power is shown
in figure. Once input V is less than 250V, the relation
of I/P V and load % is : Load% =
0.4 x Vi
1. This is voltage range that inverter will start to feed
power to grid.
2. The DC resistance requirement for positive or negative
terminal to chasis ground
3. In VDE0126-1-1, it is ¡V20%/ +15%. DK5940, RD1663 are
also available.
4. Based on the limit of VDE0126-1-1
5. Based on limit of IEEE929
6. Under the output voltage is 230VAC
7. Under utility voltage THD<3%
8. under input voltage>= 400V, full rated output power,
