Hi Mike,

 

Perhaps you can now go back to pre-paid?

It will not cost you anything to keep the power supply alive and it will still be available for emergencies...

 

What is your plans for the Imeon Hybrid?

Hi Wetkit,

 

thats not a bad idea.... i will check into that with our local muni sparkie.

 

Most likely use it in the next install i do. it is new not been switched on yet......

Hi Buks,

I have the same issue with the DC battery voltage. For now I have just compensated for the error in the software settings.

So if your set point should be 48V and the unit is reading 0.8V low, you run your setting at 48.8V.

 

I am not worried about the PV voltage.

 

Hi Wetkit & Buks

 

This might fix your problems with the readings that are not spot-on:

Battery voltage calibration (1 November 2014) from http://www.ostrovni-elektrarny.cz/index.php?page=podpora

Thank you Superdiy for the volt cal file. It worked .

I also used the program to increase my max input frequency from 50.1 to 51 HZ

I did not have the Factory password on the Infini / Replus SineON IH3KW-48-v SolarPower software

I have a rebranded Infini so that might help me as well.

It would be great if you could give some description of that program and how you used it.

Thanks

Hi Maurizio

Use a RS232 to USB converter cable

Download http://www.ostrovni-elektrarny.cz/support/Voltronic/AccessPort_and_SOP_battery_calibration.rar   

link from Superdiy   and calibrate the batt voltage as per (Infini3KW bat voltage calibration sop.pdf) file

Then check page 21 on RS 232.pdf file (Set grid output frequency high loss point)

Type   GOHF51.0 and hit enter and then send button .

The inverter will reply with (ACK9

Then Bobs your uncle

 

 

 

 

RS232 Protocol.pdf

thanks Kwagga.

I am actually using a rs232 to wifi converter.

I had done most of that but then reading  instructions in Infini3KW bat voltage calibration sop.pdf I became unsure of what to do probably because I could not see any actual battery V values in the pdf but just "send the “BTVA+01” / “BTVA‐01” command as below"  and I could only guess what that command BTVA actually does: maybe adjust LCD reading by 1  volt up or down?

I had been looking for explanation of that BTVA command in the RS 232.pdf file (BaTtery Voltage Adjustment ?) but I could not find it.

Your "Type   GOHF51.0 and hit enter and then send button" plus the reference to page 21 on RS 232.pdf file goes a long way in understanding what I am supposed to do and why before I do it.

Hi Maurizio

I had to send "BTVA+01" maybe 20 times to get the voltage on the display  to read 0.6volt higher with the inverter replying (ACK9   accepting the command each time.

I then send command    "QPIGS" Device general status parameters inquiry"  page 5 to check voltage against my multimeter

My voltage went up by 0.03 Volt each time that i had sent the "BTVA+01" command

 

Thanks Kwagga !

After a bit of trouble (packet timeout through wifi I think... I must have something not set 100%)

my persistance in sending the command a few more times paid off and eventually I managed to get back from the inverter a (ACK9 message

Afterwards I decided to reduce GOHF to 50.4Hz (I seldom go above that limit) and that is what I now get in my SolarPower parameter settings:

Therefore: no factory password is required to change grid-connected frequency values. I suspect the same procedure may be used for other changes but be warned that if you have no idea of what you are doing you might damage your inverter.

I decided not to go as high as 51Hz as Kwagga simply because I am not convinced that, at least in my inverter, the battery kicks in when power grid frequency exceeded the default upper threshold of 50.1Hz.

In my case I simply get hundred of warnings but I have no real issue with E/L tripping (even if if neutral and ground are not bonded on the inverter output). I have however some observation on E/L issue which might be of interest to others but I will spell them out in a different section.

 

Just remember the following when you do the calibration:

• Use a calibrated multimeter / oscilloscope to measure the voltage
• do the voltage measurement on the battery connection terminals on the inverter, not at the battery bank
• only calibrate the voltage when no current is running to or from the batteries, because if you do the calibration while the batteries are charging or discharging you might have a voltage drop inside the inverter and then the calibration will not be accurate.

So i have started changing again, I am removing my 11 x 275's pvs and replacing them with 20 x 300w Rena Sola panels - two strings in parallel - one facing slightly North North East and the other North North West. i am of the hope that it will cover the full sun sectrum from 8 am to 5pm and i can double my collection - especially in the winter months.

Hi Mike

I would like to known, Your system still ok.(20x300w two strings in parallel with 1 3kw plus infini inverter).How about this system. I plan to start install it with 3kw santech inverter.

Best regards

Wait for your reply

Thanks

morning, yes mine worked fine with them on, just make sure the Santech max ampage is 18amps, then you should not have a problem. i have already upgraded a few times, now on 5kw+ Infini

If I have a 3 phase application, and I am interested in the SMA Sunny Tri-Power 2000TL. Any one tell me, do I need 3 of these Inverter (one per phase), or do I only need one Inverter (i.e does the Tripower have 3 phase output.

So i have upgraded my system now for the last time ....( i think )

2 x SMA Sunny Islands 5kw each linked giving me 10kw Bi Directional power and on the load side connected a SMA Mini Central 11kw GTI, coupled with 3 strings of 12 x 305w PV panels and onto my existing 520ah battery bank....The GTI was giving me 85kwh per day in Jan and today it's giving 46kwh.......that's it done and dusted!
