luminous inverter making beep sound

[Rickysin]

My luminous inverter is making 1 beep sound every 30 seconds. Can anyone tell me what is the issue ?

@Sushubh TIL about ph levels

I have always filled water according to the level marks. Fortunately no issues still it's working but now after 10+years it has started showing some weakness signs. Lights fluctuations even when main power supply is on. Or it could be because of inverter or main supply idk.

My inverter also required only minor repairs about 2-3 years ago. Still working after 10 years.

Really good machine considering it remains always on with so much dust and hot weather. I doubt if I buy a new one now the quality of equipment will be same.

Give an AMC to one of the nearest UPS shops. Costs 400 around my place for 3 services. They carry a hydrometer to check the gravity of the electrolyte.

Lol I can't seem to find anything about pH values online. All articles say to fill till green mark or something. I guess pH value is retained as long as there is enough water in the compartment. Overfilling is not recommended. We tend to overflow water while filling which is not optimal thing to do

As Nishant said it is related to density of the liquid lol. Hydrometer seems to measure that.

 

[Nishant]

It is not pH level but gravity of the electrolyte. Each cell needs to be checked and a certain level indicates that the cell is completely charged / specific voltage denoting a full charge.

Found this chart that seems to be accurate.

raised a complaint to luminous and they are going to send technician today. lets see what he says.

battery is not old as i bought it 2 years back.

@Rickysin your pcb has gone kapoot I guess.

 

[Rickysin]

Yup motherboard gone. Quoted 2500 rs for replacing that.

Will get a new inverter by spending 2500 more and will get 2 years warranty

Avoid luminous next time. Had same problem.
Replaced with microtek pure sine wave. Even vguard has good reviews. Pure sine wave is a must.

 

[Rickysin]

Yup i also have microtek sine wave inverter and its been 7 years and it is still working fine.

 

[Sushubh]

mikrotek service support is also very expensive outside warranty. i have gotten a new piece instead of getting old unit repaired because of same reason. they charge 50-60% of the cost of the new unit for the pcb and it comes with no warranty. the other option is to pay 25-30% of the cost of a new unit in AMC.
