4.3 Ambient temperature

The solar inverter can be operated in an ambient temperature between -20°C - +60°C. The fol-
lowing diagram illustrates how the power supplied by the solar inverter is reduced automatically in
accordance with the ambient temperature.
The device should be installed in a well-ventilated, cool and dry location.

5. Wiring the Inverter

5.1 Preparation before Wiring

1. To avoid accidents, please confirm that the PV inverter's power of both DC and AC are
switched off.
2. Please confirm whether the input/output of PV inverter's wiring are clearly indicated. Make
sure that the value, polarity, voltage and phase are correct.
3. The wiring procedure of a PV system is shown in figure 5-1 and 5-2. Wiring details are de-
scribed in the following paragraphs.
• When the DC input is floating, an external transformer is not necessary. Please refer to
Figure 5-1 for the connection. The inverter can accept DC inputs in parallel (1 MPP tracker)
or separate DC input connections (2 MPP Tracker).
• Operating in parallel DC inputs (1 MPP Tracker)
- Inverter MPPT:
- Boost MPPT:
• Operating in separated DC inputs (2 MPP Trackers)
- The max. rating is 10.5kW/30A for each input.

Power sharing decided by each input's impedance
> 10kW, inverter will force to balance the DC1 & DC2 power
< 10kW, inverter will not force to balance the DC1 & DC2 power
