One inverter can only be communicated with one PC at the same time through RS232
port. Thus this method is generally used for single inverter’s communication, for exam-
ples: software updating and serviceman’s testing.
9 Troubleshooting
This section contains information and procedures for solving possible problems with the
Hosola inverters, and provides you with trouble shooting tips to identify and solve most
problem that can occur with the Hosola inverters.
This section will help you narrow down the source of any problem you may encounter.
Please read the following troubleshooting steps:
1.Check for a Warning or Fault message on the System Control Panel or a Fault code
on the inverter information panel. If a message is displayed, record it before doing
anything further.
2.Attempt the solution indicated in Table 8
3. If your inverter information panel is not displaying a Fault light, check the following list
to make sure that the present state of the installation allows proper operation of the unit:
(1) Is the inverter located in a clean, dry, adequately ventilated place?
(2) Have the DC input breakers opened?
(3) Are the cables adequately sized and short enough?
(4) Are the input and output connections and wiring in good condition?
(5) Are the configurations settings correct for your particular installation?
(6) Are the display panel and the communications cable properly connected and undam-
aged?
