that all cells are performing correctly and are properly charged. Any
serious imbalance should be reported to your system designer in case
remedial action needs to be taken.
Fault Finding
No indicators ON when power is first applied
When first connected, if the LD250 shows no indicators the battery
connections may be reversed. Check that the red battery wire (6) is connected
to the battery positive, and the black battery wire (7) is connected to the
battery negative.
Radio Frequency Interference
Radio Frequency Interference (RFI) can be a problem for owners of inverters.
RFI in a domestic situation may produce noise or interference on a radio or
TV receiver.
Inverter shuts down during the middle of the day, and comes
back ON late in the afternoon
Considerable development time has resulted in a reduction of the RFI
generated by the inverter to a level that complies with C-tick requirements.
Compliance to this standard means RFI is low, but how well the inverter
performs in a particular installation can vary. Below are some suggestions to
help reduce the effects of RFI in your installation;
This is more than likely caused by high battery volts during peak charging
times from Solar Panels. Battery volts should never exceed 34 volts. If this is
the case, have your Solar Regulator checked.
•
It is recommended that the power system including the inverter be
housed at least 15 metres from the home.
•
Ensure an earth stake is placed as close to the inverter as possible and
connected to the inverter via a short length of wire. See page 2 for
wiring details.
•
Avoid running DC cables into the home, if at all possible. If this
cannot be avoided, run DC and AC in separate conduits separated by
as much distance as practicable. All DC wiring should also be kept
together and be as short as possible.
•
If your inverter is to be installed in a mobile home or similar, try to
keep your inverter at least one metre away from your radio or audio
equipment. The further the better.
