failure to Start Some Devices on Load
Some high capacitance loads like Compact fluorescent Lamp (CfL) or Switched Mode
Power Supply (SMPS) will shut down the inverter under overload condition if the inverter
is switched oN with these loads in oN condition. However, if these loads are switched
off first and switched oN only after around 10 sec after the inverter is switched oN (as
already recommended under switching oN procedure), the inverter may not shut down.
Hence, do not switch oN the inverter with such loads in oN condition.
monitoring of operational Status & protections
Normal / abnormal behavior can be monitored by observing Green LeD (5, Power), Yellow
LeD (6, Input fault), red LeD (4, fault) and buzzer. Details are given in Table 6.1 below:

remedy/reset
-
Check battery voltage and
input voltage drop.
Auto reset when voltage
> 10.5 V ± 0.3V.
Check battery voltage and
input voltage drop.
Auto reset when voltage rises
to >11.5V.
Check charger voltage.
Auto reset when voltage
< 15.5V.
Check ambient temperature,
fan and loss of cool
replacement air .
Auto reset when hot spot
cools down 10°C to 15°C
below the threshold.
