Also please specify the max wattage of the inverter? If it was I was thinking that the unit will switch off completely. My inverter trips with overload indicator coming on when power fails, it continues in this condition even when all load is disConnected and the inverter is reset. Both main plug for shore power, and shore power pedestal have GFCI outlets. Pls what do u think i can do to that? Hi! Inverters so connected with single battery because I have my 300Wp solar panel of 36Vmp so I have connected them in 24V from 12V & getting better result. It seems like there is a short occurring when anything is plugged into the outlet. Is there a component inside the inverter that would make the inverter revert to overload even with brand new batteries and everything else is fine?No tripped GFCI, or inline fuses blown etc. Sir,i have a 1.5kva inverter.My inverter shows short circuit on the dashboard but I have changed all the mosfets and even capactiors.i noticed that only 4 mosfts get hot on powers the inverter out of the 8 mosfets used.what could be thhe problem? One more is if we touch the two pins of B22 base with metal it lights up. i would like ask for learning and understanding in this UPS. which capacitor film should I need to connect it to the output of TP850VA square wave inverter? The unit looks clean inside (no dust on fan) , all the fuses (on the board & cabinet) looks fine. If yes, i shall replace my inverter with the better quality one, since I bought the Inverter via Online only 5 days back, so I return it back as damaged product. Hi, Normally a good inverter will not fail even if its outputs are short circuited, so a tube light should have noway affected its operations. It suddenly started making vibrating sound with a hurriedly beep when on Battery Mode and after a while it drops the battery bar from 4 to 1 bar with “UNUSUAL” display on its LCD and later switched off. The only quick remedy for this is to add a good quality electronic fan dimmer with the fans and reduce the speed appropriately. 3 0 obj
The problem could be with your fan and or with your inverter, most probably it could be with your inverter….I think the output harmonic filter circuit might be malfunctioning, an involved capacitor might have gone short or faulty. The result of this could be serious damage or minor, can't pinpoint without checking, you can check the fuse or the parts around the fuse…also the mosfets could have gone faulty probably, i have a invertor of Luminus Tez and we see that before some time battery is not charging and Charging Zip is blinking continuously , we clean the battery terminal and even not charge battery…plz help. Thank you again. Thanks brother. I replaced the Fuse and connected the battery/inverter connection and now the beep sound is not coming but when the power goes down again inverter starts giving High beep sound. 3) Occasionally, transformers can also become the major cause for a malfunction. Sometimes when the power goes off, the inverter immediately goes off to low battery. Hi, I compared the pinouts of your inverter IC with a more commonly available IC TL494 and they looked exactly similar. 3) These pinouts can be seen connected with the relevant power devices #1, and #2, which could be mosfets or power BJTs. The important thing would be to check whether the battery voltage is reaching the inverter or not. Hi,swagatam.I have a ups using with my p.c.When there is main it gives 250 volt output;but during the mains off,it gives only 150 volt.I checked the battery is o.k.then what may be the problem? I have this TBE 1000W power inverter that was working fine until it made this long beeping sound. please download the following pics may be you'll find the problem because, there is another relay and physically is good but I haven't test it, https://mega.nz/#!QcZWhAbZ!A0gvwNFx3e_gDiUKOo4qz-eqANfgbaqnKdP8MkrghYw, https://mega.nz/#!5VIlnaSR!MDXLriAU6kUqGdxbCO7o_obfenSFPjCOADVdcYePgaI, https://mega.nz/#!9U4SRSyK!YZIgaSCleGPbxcS1GeiN6bhdYZxiyvfCOfNtdwIdN-c, https://mega.nz/#!QV4S2aab!8z7R_LL1jHEWfLp4doXpjvzb8Gl0R2xTc5BifJIj-kE, https://mega.nz/#!RJACUIpK!ikEvHfv9qV1KSbQ5oLugydJrML6bhwbvxb1KNobPNw8.
