Posted July 21, 20186 yr Please assist me , I just installed the synerji inverter with 9x275W panels.My inverter shows (on the display ) PV 106V 0.13W. Does this means my PV produces 130W?
July 21, 20186 yr If it says 0.13kW then yes, if it says 0.13W then no - but I am not familiar with the Synerji, I believe it is an Axpert copy.
July 21, 20186 yr Author sorry 0.13kW , I was expecting 275x9 = 2475 W.I am new in this field. Thank you
July 22, 20186 yr Hi Thembeni - welcome. I had a Synerji for a short time. I was not happy with it and re-installed my Axpert.

Thank you Hi Thembeni, the power of 275Wp x 9 PV modules (2475W) is just a possible maximum that in reality is limited by a number of factors. The power (watts) is a function of Volts x Amps, so if you have only a very small load connected to your system(ie: laptop), then you have the Volts but you're drawing just a very little Amps. Therefore, there's not much power generated/consumed. Solar power works like that both these two conditions have to be met at the same time in order to generate the power: the sun has to shine directly on the PV modules you must have a decent load turned-on If you don't have any load connected, then the only other place where energy can go is the batteries. So, if your batteries are empty, then you will see some power being generated no matter that other loads are off. Actual power will be limited by amount of panels, technical parameters of your solar charger and by the solar insolation, of course. Once your batteries are full, they virtually stop drawing a power. So, charge your battery, wait for the perfect sun and then turn-on some huge appliance like geyser, air-condition or a stove. Makes sense? Edited July 22, 20186 yr by Youda
July 22, 20186 yr Author Thanx for the information, I am now stressing because it not working according to the expectation

Thank you, I tried to maximise the load to 1kW and i got battery alarm and the sun was shining directly to all 9 panels
July 22, 20186 yr Thembani is it a DIY install? - in which case we will try and help you. If someone else installed it phone them and get them to come and sort it out.

July 23, 20186 yr Here is a trick. Go and count the little squares on your solar panels. There's going to be either 60 or 72 of them per module. It is hard to say, because usually a 250W module will be 60 cells, and a 300W module will be 72, so I don't know where your 275s are, but I suspect 60. Now consider this picture: Note the PV voltage of about 105V. If you have 3 modules of 60 cells in series, that's 180 cells. Divide 105/180 ~= 0.6V. That means the panel is unloaded, it is not doing any work. A panel that is working pulls down to 0.5V per cell, or around 90V in this setup. If you have 72 cell modules, then the voltage is right, but the current is about a quarter of what it should be, which makes even less sense. That is why I guess you will find that they are 60-cell modules. Now that is so terrible that you might as well connect the PV panels directly to the battery (not permanently, just as a test) and you will get 10 times more power than you do now. Specifically, it will pull the panels down to 47V (the battery voltage), but it will work at the panels Imp which should be around 8 amps, that's around 380W per string, or over 1kw. I also note that your batteries are very low. 47V while receiving a low charge is practically empty. Finally, I'm a little concerned about your PV wiring. You have 3 of them paralleled up, and it looks like normal 25A household wiring. At 8A per string, you're about at the limit of what that wire can handle.
July 23, 20186 yr Author Hi, I have counted the cells are 60 ,I have 3 strings of 3 panels connected in series and paralled in the fuse box
July 23, 20186 yr 7 minutes ago, Thembeni said: cells are 60 Then your MPPT is counting toes as we say in my mother tongue when someone is wasting time instead of doing work. This could be because it is incorrectly configured (doubtful, as 47V is low enough that even bad settings should charge), damaged, or just plain horrible as @Chris Hobson also found in his review. My upper-gut feeling is that you should try a different MPPT, but I understand that you may not be close to a shop that sells these, nor are they exactly cheap. Even if you just installed a cheaper PWM controller in there (as a test, a backup, or an interim plan) you should be better off than you are now. My lower-gut feeling is to toss the inverter and get something better. Like an Axpert. Can't believe I said that... :-P

July 23, 20186 yr Hi Thembeni What is the installs location? I am guessing Bloemfontein. I have to be there in the next 2-3 weeks and can come and have a look.
July 23, 20186 yr 1 minute ago, Thembeni said: In Welkom Ok we are going to have to do this the hard way. If you push enter for 3 secs you then get into the menu of the inverter could you list all your settings.
February 26, 20196 yr This is all true except for one thing. The synerji invertor has also grid feedback capabilities. If setup to do so one can push back excess power into the grid.

Thanks.

Thanks. as long as we are talking about the same model inverter synerjy 5kw + mmpt that's the one i have 2 settings deal with what to do with the power generated in the settings #5 gives you two options LBU - Load Battery Utility or BLU Battery Load Utility so essentially you can choose what is more important supplying load or charging battery first the moment those two are met the rest goes to grid also keep in mind the battery will be charged with the amps you selected in the settings, so even if the battery isn't fully charged the moment it's at the max amps the rest can go to grid, so you could be feeding into the grid while battery isn't fully charged if you have devices connected pre inverter they would absorb what you pushback before the rest pushes to grid ie reducing what they draw from the meter if you have any loads active during pushback you can enable or disable grid feed in setting #9 the 2 options with imagination you can see the first 2 letters as Gr ie GRID and the third letter d or E d is disable grid feed and E is enable grid feed though the r could have been done better imo it looks nothing r it looks like a r with a giraffe neck on the bit that was suppose to stick out Edited February 2, 20232 yr by Leondavibe adding more info
