sohail anwar Posted June 7, 2016 Share Posted June 7, 2016 hello every one.i hope i get some help through this forum.i have a Advanced Energy grid tia inverter model number 3tl 24k 24000watts it is a pv inverter i am having problem understanding its on-board settings.after installation when i turned it on it shows error sign.on display it says grid under voltage and grid frequency error.will some one tell me how to fix this issues Quote Link to comment Share on other sites More sharing options...
Jaws Posted June 7, 2016 Share Posted June 7, 2016 When you say switched on do you mean when you power it up from the grid supply? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
sohail anwar Posted June 7, 2016 Author Share Posted June 7, 2016 it doesn't turn on without grid supply. it has a pv switch to turn it on and off.if you please check the pics which i have attached with the message. Quote Link to comment Share on other sites More sharing options...
sohail anwar Posted June 7, 2016 Author Share Posted June 7, 2016 i think it requires a software setting.and i dont have a manual or a cd to configure it through pc. ___ 1 Quote Link to comment Share on other sites More sharing options...
Coulomb Posted June 8, 2016 Share Posted June 8, 2016 Do you actually have 480 V 3-phase to connect it to? That's a big inverter. Most countries have 380/400/415 V 3-phase. ___ and Mark 2 Quote Link to comment Share on other sites More sharing options...
sohail anwar Posted June 8, 2016 Author Share Posted June 8, 2016 i have 200vac on each phase Quote Link to comment Share on other sites More sharing options...
___ Posted June 8, 2016 Share Posted June 8, 2016 Some confusion here. Usually 3-phase means 380-400V between phases, and 230VAC between each phase and ground. If you only have 200V per phase, it's very likely that some inverters won't tie with that. You'll need to change the settings. I'm not sure if anyone else here has heard of that inverter, but it was made in the USA where standards are different, so I doubt any of us here has seen one of those.

sohail anwar Posted June 8, 2016 Author Share Posted June 8, 2016 you are saying that i must have 230v on each phase and ground??and which settings are you talking about? ac voltage setting pv settings or inverter internal settings? yes this inverter is usa brand and i am looking for its manual or a program CD or a way to set it up according to my regional settings Quote Link to comment Share on other sites More sharing options...
sohail anwar Posted June 8, 2016 Author Share Posted June 8, 2016 the Standard AC voltes in my country is 220V and operating frequency is 50to 60 hz Quote Link to comment Share on other sites More sharing options...

Coulomb Posted June 8, 2016 Share Posted June 8, 2016 The specification label says 423 V minimum (I assume that's phase to phase). So that's 423/sqrt(3) = 244 V phase to neutral. That might actually work most of the time where I live, but it would not be reliable. It will also need to see all three phases, so it can see the 423 V or more phase to phase. Edit: so unfortunately, this won't work in your country. Regie 1 Quote Link to comment Share on other sites More sharing options...
sohail anwar Posted June 8, 2016 Author Share Posted June 8, 2016 yes dear i have e mailed them and ask for solution.is there any way i can turn ot on by setting its software accordingly? Quote Link to comment Share on other sites More sharing options...

sohail anwar Posted June 8, 2016 Author Share Posted June 8, 2016 let met correct myself hare.it is 428v phase to phase. Quote Link to comment Share on other sites More sharing options...
Coulomb Posted June 8, 2016 Share Posted June 8, 2016 428 V is only 1% higher than the bare minimum. You might find that say phase A to phase C is only 422 V, under the limit. This will vary from minute to minute as loads come on and off, many nowhere near the inverter. Usually, specifications on the label are absolute limits; you likely won't be able to go past these limits by changing software or configuration. I think you've been sold the wrong inverter. For example, 24 000 W is about 4 times the largest inverter for a house, and possibly 8x to 12x the average inverter. Is this for a community, or a large farm? The panels needed to feed this beast would not fit on a single house's roof. Quote Link to comment Share on other sites More sharing options...
Jaws Posted June 8, 2016 Share Posted June 8, 2016 let met correct myself hare.it is 428v phase to phase. Grid tie inverters can't work without being connected got the grid, you need the grid for the Inverter to switch on, you cannot run a grid tie inverter with only the PV panels connected . In this case the inverter needs to see 428 V on all three phases. As to your question if this can be bypassed with I simple software setting - I don't know as these inverters are not common in RSA but in all probability not.

I'd say it is able to power its microcontroller from the grid he has, but the microcontroller must have decided that the grid voltage is too low to invert into. It would only need a few watts to drive the microcontroller, display, and associated electronics. ___ 1 Quote Link to comment Share on other sites More sharing options...

Should have said grid tie inverters will not turn on if not connected to a grid supply that is within the specified values, and with turn on I mean take the solar Input and inverted it into AC power Sent from my iPhone using Tapatalk ___ 1 Quote Link to comment Share on other sites More sharing options...

I doubt if the OP is in South Africa. To the OP, I suggest you contact the manufacturer or supplier of this inverter and ask them the recommended settings for your setup, and avoid potential damage to your inverter or load.
