I only have two CT's on the mains in live feed. One to the Growatt SP2000 control unit and the other to the Immersun Mk.II.

Currently I'm not sure how the system can work alongside the Immersun without some conflict at certain points.

Thoughts welcome.

I route the live feed to the ImmerSUN through the CT clamp for the battery in parallel with the building supply.  That way the battery is prioritised over the ImmerSUN since it sees the sum of export and diversion through the ImmerSUN, and the battery responds to take the load.  The ImmerSUN then backs off as required to avoid import as the battery charge rate rises.

Otherwise Im not clear how you would force priority of one system over the other.

Good Evening All,

I've had a reply from Immersun wrt to a 'hard' reset:-

To do a full reset of the unit please follow these steps:
1. Switch Immersun off for 30 sec.
2. Push and hold button X and Tick and then power up.
3. This should have reset the unit. You will then need to go through the setup again to configure unit as required.


Nick - I noted your post under the 'Battery charging with an Immersun T1060' about what you were doing to prioritise the CT's. My 'challenge' is the fact that the incoming mains is on the far side of the outbuildings and the CU is in the kitchen. The PV output is collected on the near side of the outbuildings (where the Immersun 'export' CT is located) then led over to the far side.

First step is to see where we are after resetting the Immersun.

Regards

Good Evening Again,

The screen shot has just been taken so clearly the Growatt battery is discharging though the inverter which is something of a relief after much confusion last night.

Regards

Richard

Good Morning All,

I'm not sure how to determine how much power I'm getting from the Growatt. The Immersun CT is giving me a figure but this is somewhat less than the Growatt unit itself shows. Overall the Immersun has proven to be within 5% of the TGM's as far as PV production goes.

In the period 7 - 20th May the Immersun shows 20.2kW 'gained' in night time 'generation'. I have no remote monitoring facility but daily observation of the 'Ed' figure from the Growatt is larger than the Immersun is showing.

I might have to run some tests on the individual battery packs to see how balanced they are given the unit was sat for at least 10months.

On a positive note the system is running quite happily and I'm able to get on with other things.

I'm still seeking a post Wk01/15 Aurora/ ABB PVI 3.6kW inverter............

Regards

Richard

Good Afternoon All,

The next 'upgrade' is in the process of happening i.e. I'm installing a G59/ 3 capable SMA SB3000TL-21 inverter and the Aurora is on its way out. It is now an SSE compliant install and I feel so much better for it  stir

Now I'll need to wait for a wee hint of sun tomorrow not that the sun gets much above the horizon for very long here at this time of year.

It's currently set to 0:1 and I'll shortly be resetting it to 5:A, I suspect it may not allow me to change it as with it being a second hand unit it must have run for 10hrs.........., it would be too much to hope it would be straightforward.

Regards

Richard

Good Afternoon All (again),

I'm sure there is a good reason why SMA feel the software needs to go into lockdown so you can't readily change the parameter settings.............

Time to start reading the manual and accept any advice from more knowledgeable forum members on the simplest way of changing the settings Smiley

You need a grid guard code from SMA, just email SMA for one.

You type it into Sunny Explorer and that allows you to change anything.

Mike,

I have just read both the inverter and the Sunny Explorer manual and was hoping this didn't need the grid guard code option but OK I'll get on with sending SMA an EM........

59 + VAT - daylight robbery if you ask me. You can download the necessary code from Aurora for free!!!!!!!!!!!!!

Good Morning All,

The good news is that we have a fairly cloudless day here and the new inverter is up and running and I have managed to establish Bluetooth communications with it.

I'm not sure what level of access I have to it but I was able to access the assorted country settings and there was a source of disappointment/ confusion somewhat akin to that with the Aurora.

If you Google both the Aurora PVI3.6 and the SMA SB3000TL-21, downloadable specifications will tell you both are G59/3 friendly however this clearly isn't the truth, the whole truth and nothing but the truth.

In the case of the Aurora you need a post December 2014 model and I have yet to find such a beast!

From the list of alterable standards on this here SB3000TL-21 I only have G59/2 and no sign of G59/3. I have 'told it' to change to G59/2 and the LCD display indicates that that is what it is currently running but I'm not convinced currently.

The display is telling me I'm running FW Pack 2.60 HP 2.52. I've been on to the SMA site and downloaded updated firmware which is FW Pack 2.81.01 HP 2.53 so am now just reading up how to carry out the upgrade - something about light the blue touch paper and retire to a safe distance?Huh?

Well the inverter didn't like the first 4GB SD card so I tried another 2GB one, it tried reading the card and advised no firmware update was available?

I've just sent an EM to SMA UK requesting help/ advice.

Regards

Richard

Hi Richard
I am sure that if a specification is not there you can manually set all the parameters.
If you don't have G59-3 just get the parameters as a list and set them in manually. The listed ones are just for ease of setting up. Unless you can get the updated firmware loaded.

Iain,

That is certainly a route which could be followed. I seem to be at a halfway house as I seem to be able to alter some settings. When I get the chance I'll have a look at how it is currently set and see if I can alter a setting.

I'll now need download G59/2 and G59/3 settings from somewhere........

Good Morning All,

If all else fails read the instructions carefully is today's guidance........

I re-read the upgrade instructions again about 30 minutes ago and a light went off. The instructions actually instruct to download the Update folder containing the two files whereas I had just downloaded both files.

This explains why the screen message was 'No Update folder found'.

I just uploaded the folder entitled 'Update' to the SD Card and tried the upgrade again and lo and behold it went through without a hitch. Further more I assume as it detected I had set it to G59/ 2 yesterday it seems to have automatically upgraded it to G59/ 3 as this is what showed when the inverter re-booted.

Better send an EM to SMA so they they can 'stand down'............

Regards
