Did you ever get this working?

Hi all. I just bought a MUST LP1600-24200 battery. Accorging to the manual, I can set the protocol in the settings on the screen, but when I go into "Para" I get "--Non production manufacturer can not use". I'm guessing there is some key-combo to get the battery into installer mode? Any ideas? This is to connect to my Growatt SPF-3000 Inverter. I'm guessing setting both to the same protocol will do the trick. Thanks

Thanks

Morning all. A while ago I was forced to quickly get a backup going for my fridge due to a vandalised minisub. Either way, I bought one of these: https://www.fivestarled.co.za/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=164&virtuemart_category_id=19 Very human design. Does anyone know of software I can use to read some values from the controller?

Good morning all you smart people I have the inverter in the title. Works like a bomb, love it. I do have a couple of questions. I use (SolarAssistant connected to USB to monitor my vitals) I have 2 x 120ah LifePO4 batteries https://sjandrews.co.za/shop/s-j-andrews-2/lithium-batteries-s-j-andrews-2/lifepo4-lithiums120-12-8v-12kwh-s-j-andrews/ They have built in BMS but no comms. Question 1) My load being reported by the inverter seems to be uncalibrated. I have a server running 24/7 on the load (+-55Watt) that is not reported by SolarAssistant. Solar assistant has a pseudo BMS where is can calc your SOC, but because this load isn't reported, it's inaccurate. Is there a way I can calibrate my load reading? I've found the "secret menu" on the growatt. in there you can change the voltage of the load, input and battery. I've measured with a multimeter and made a 0.1v adjustment, but it had no effect on the load being reported. Should I make a bigger adjustment? Question 2) If I decide to go rack mount Lithium with Comms port, how do I know the comms will work with the inverter? According to the manual only one battery is supported and that is not available in SA. Surely something popular like a pylontech or Giter should work? Thanks

Sorry to dig up an old thread, anyone ever found out about these settings? My inverter's LOAD is out by about 50 Watt, I would love to know if these settings could calibrate that.

Morning all As per title these things are out of stock everywhere. If you know where I can get my hands on this unit: https://www.ellies.co.za/product/microinverter-hoymiles-1200w/ please let me know. (Ellies out of stock) I'd also like to keep my panels the same, 330W Canadian solar. Also cant find that at the moment. Thanks in advance

Thanks for the info, helps a lot

Good morning everyone I have a Hoymiles grid tie inverter, and wondered if anyone successfully got these to "sync" to a generator or even a modified sine wave UPS. Thanks

I bought them at Ellies in JHB. Just make triple sure you get the right stuff, I went back about 4 times before I had want I needed.

Hi everyone, (this is my first post) I want to install a Hoymiles grid tie micro-inverter setup at home to supplement my usage with solar. I have prepaid electricity with a Landis Gyr meter and i do NOT want to push back any excess into the grid. The information online on the setup required to achieve this is incomplete, scarce and chinglish ect. I need a DTU with Zero export capability (or anti reflux as Hoymiles calls it). Then I need a power meter to measure the load of my house. The current meter is suppose to connect to the DTU via RS485. So I spoke to the ellies consultant and I put together my order. I collected it today but things don't match up. Ellies only has 1 type of DTU on their price list and it is specified as a Zero Export GSM DTU. The DTU I received does not have a GSM module (no sim slot) and does not have an RS485 port. It has a RS232 port. The power meter has a RS485 port. These wont talk to each other. The config settings on the DTU does have a check box for "no export", but an input field with an ID. ID for what? the value in there at the moment is a 6 characted hex value, not a single digit ID i would expect from RS485 comms. I suspect the DTU they gave me is a newer version that wirelessly talks to Efergy current sensors. But those have a minimum 6 second polling interval. Surely this is not sufficient to stop exporting to the grid. Worst case scenario you will export max array capacity for 6 seconds. While this is illegal, I also understand that I will be charged by my prepaid meter for this electricity that i pushed back. Any advice from anyone that have installed one of these systems would be greatly appreciated. Francois
