My installer was a cowboy and is now out of business. I plan to check and maybe reset the Country Code on my SPH 5000 invertor. I have found from this forum that the necessary 'secret code (key password)' to access the appropriate menu is 1111, and as I'm in the UK plan to change the code (if...

I know this is a long dead thread but AFAIK you just need to set the RS485 address to correspond with the invertor's address, and an 'ordinary' SDM230 should work. I've been using mine for months and balance is good - normally 0 to 20w exported from the battery (down from 100 to even 200 with...

Hi, thanks for the reply. However, I deliberately want to stop the inverter charging the two Chinese batteries, as they do not communicate with the invertor. The GBLI 6532 battery talks to the invertor, but the Chinese batteries are not connected and they reach full charge before the GBLI 6532...

Hi, I have a SPH 5000 hybrid inverter, GBLI 6532 battery (6 kWh) and have added two 'Chinese' 3.5 kWh batteries myself - thus doubling the storage capacity of the system from the original 6 to around 12.5 kWh. Monitoring of the 'Chinese' batteries is not connected to to the invertor, but I have...

Nope, unfortunately! Any more thoughts please?

As I said I wonder if it's the CTs used, and if a meter like the SDM630 would help (the SDM230 for my single phase setup helped a lot...)

Thanks... I had (belatedly!) worked that out but it's good to get confirmation. If you have three or four batteries in parallel, the wiring must get a lot more complicated to achieve equal lengths...

Especially if the monitor(s) on the main meter lead is/are a CT(s) as opposed to a wired-in meter like an Eastron SDM230 (or SDM630 for three-phase). I was 'leaking' a continuous 50 to 100w with a CT, which has dropped to nearly zero with a meter... Only issue with a meter is that you have to...

Hi, I have a Growatt SPH5000 and GBLI6532 battery, which is 6.5kWh storage.. I've recently added two 'random Chinese' batteries in parallel - the individual batteries are about 3.2 kWh each so I've essentially doubled my battery storage to 12.6kWh ish... The two new batteries are connected in...

On the inverter you can set the RS485 port number and also baud rate. The Eastron port should (obviously) be the same - but in my case both were already #1 and 9600 baud, and worked out of the box. Good luck.

Also, have a look at this Solar-Assistant page - https://solar-assistant.io/help/growatt/sph-range There is a chart there for pin-outs for all the connectors for the SPH range - the relevant column is the meter column.

Good luck... It works for me, but I hope it's right for you! Are you in the UK?

a) The socket is marked CT1/METER1 on my SPH5000. b) The current Growatt manual on the ginverter site has up to date instructions. c) The second picture shows my ethernet cable connections... (disclaimer ... yours just may be different!). I just used cat5e cable but maybe screened cat5e is...

Hello, please where do you set the maximum charging voltage? Thanks!

Hello, this is a MOST useful thread. I have two 48V (nominal) 3 kWh batteries, working well but also throwing over voltage alarms when getting 100% charged (cell voltage difference goes up to ~200 mV, over volt protect activates and voltage difference rapidly drops to 50mV or less). I have...

I've a Growatt SPH5000 and 12.5 kWh battery, and have Eastron SDM230 in the meter tails to control the system. Link to the invertor is Modbus (RS485?). Does Modbus = RS485? Can I also connect a computer or Pi-device (via a RS485 to USB convertor) so I can monitor the output from the meter? Do...

I suppose it's possible but I can't say I like the idea. Many (most?) consumer units will have bus bars on the output of the main switch, to connect to the MCBs, so I can't see how easy it will be to connect (eg) an Eastron. Also, I would prefer such a meter on its own in the external meter...

Hi, I've got and installed two 3.2 kWh 'Chinese' batteries, and connected them in parallel with the original Growatt GBLI6532. (so the initial capacity of the Growatt was 6.5 kWh and the two additional batteries add another 6.4 kWh - as close as I could get to being equal). I monitor the...

Sidenote - I've used a random Eastron SDM230 (setting baud rate to 9600 and id to 1, although you can also modify the address at the invertor) and at least one other user on the forum also got a non-Growatt supplied SDM230, which worked - so I don't think the growatt 'flashing' is really a...

The batteries have RS485 and I'm using the supplied web app to monitor them, but I'd like to use SA if possible also...

The $55s all add up! I've emailed them anyway and will see if they reply. I would like to check SA works with my 'random supplier' Chinese batteries first...

I've created an account but there is no download link...

Yes, but only after you've paid. I can now see that there is the option for a trial...

Thanks - but the problem is I can't find the link to download SA. Their page seems to say the link is available when you've bought the license... This page only seems to link to a download if you've got a license... https://solar-assistant.io/help/getting-started/prepare-device Maybe I...

I've got an Orange OPi on order and plan to run Solar Assistant. However, it's not cheap to buy and I'd like to run a trial - but I can't find anything about it on their website? Any thoughts?

Title says it all really - I want to monitor and manage my Growatt GBLI 6532 battery - I'm using Growatt Shine server but would prefer to plug in RS485 and use a program on a PC. Can anyone give me any pointers please? Thanks!

OOh, that's clever! Can you give me any pointers to this please? Shine WiFi-X devices?? Cheers!

If you regard climate change as a 'cult', why are you on a Solar forum?

Reading this from the UK, this sounds rather paranoid...

Hi, thanks for the replies... I've listed the PCs at the end of my post - but here they are again! https://www.aliexpress.com/item/1005003926574260.html https://www.aliexpress.com/item/1005004302428997.html The RS485 to USB adaptors - one was supplied with the batteries, and the other I can't...

Do you have DIP switches to change the address of the batteries? I have two Chinese batteries and you can (allegedly!) put 32 in parallel, and set the DIP switches from 1-32. This works with my two batteries, with battery 1 and battery 2... I have a manual for my batteries if you are...

I have a Solar PV system with Growall SPH5000 and Growatt GBLI6532, and also two AliExpress 60Ah add-on batteries in parallel (so I have about 12.5 kWh of storage). Works well, and I am trying to use mini-PCs to monitor both the battery and the SPH5000. The batteries have RS485 output, as does...

Hello... I can't really advise and suggest you start a new thread. I assume you've found the official manual on Growatt's site? - the manual can be found here: https://www.ginverter.com/upload/file/SPH_3-6KTL_BL-UP_User_Manual_EN_202212.pdf

I've just ordered an Orange Pi 3 LTS and plan to run Solar Assistant, to monitor my Growatt SPH5000. In the interim, I've found copies of Growatt's own monitoring software (ShineBus - very out of date) and monitor the invertor using the RS485-1 port, a RS485 to USB adaptor and a micro-PC.

Final comment, I hope - I've also found a fused disconnector to fit between batteries and the invertor (the shoddy installers didn't fit one). https://electric-solar.co.uk/products/keto-battery-disconnector-with-100a-fuses They've sent an installation photo that shows two crimp leads...
