Deon_J started following Trade Equiries , 6kw Fivestar inverter error and Growatt inverter parallel setup

a client send me this image, the display is off, but according to him its still working. What can be the issue?

I have 2 Growatt inverters running in parallel with a dual lithium batteries shared by them. Each inverter has its own solar array. Question - is it possible to connect batteries to each inverter( not sharing a battery bank) Question - when adding a new lithium battery to the bank of 2 x 5.12 kw battery will I be limited to add exactly the same battery as a third or should it be one with the same specifications?

I’m in Pretoria, and have a registered company. Which companies can I approach to register and get preferred pricing for resale and possibly as installer. Any company in Pretoria and Johannesburg will do. Regards

Hi Everyone @Buyeye, @Supergeek Time for feedback, I made all the changes and the system is running like a charm. After a lot of pain I finally off grid. since I connected all the panels in series my daily production went from about nothing to an average of 9.9 kwh see the attached graph. You will see that before the 3rd nothing shows , that was the production I had before the change ( note to myself ! Even solar panels can give you quite a big shock, I covered them when I was working and touched a open wire, I nearly fell of the roof!,) thanks for the support

Hello every one Totally agree with @Supergeek However in my specific scenario I’m fixing a really bad installation, it was working ok with 2 king inverters but then they died. The insurance replace them with the 2 growatts. I didn’t notice that they need higher voltages froM the panels. After a few days I realize that I was using utility power like crazy, that’s when I started to investigate and saw that they need a higher supply. The one solar bank I could change at the fuses, ( old installation but done well) the second bank I can’t do the same, the idiot that installed them cut the connecting plugs and linked them together on the roof bringing just one positive and negative cable down using normal electrical wire!!! At some point I will need to lift the panels and check that all is ok and fix the wiring and get the panels info I will brave the heat this afternoon to change the panels from 3 series 3 parallel to 9 in series and give feedback tomorrow wish me luck its 35 deg in pta today

Just to give feedback, this morning I changed one array (6 panels 3 par, 2 serie) to 6 in serie, look at the huge difference it made in production picture 1 from today, picture 2 and 3 from the 31st Tomorrow I will do the other 9 and share the result thanks again for your feedback

Thank you, this helps me allot. I can reconfigure one set, its currently 3 parallel strings with 3 in Series (9panels), changing them to all in series give me approx. 360v. the second set has 3 in series and the 2 sets in parallel (6 panels) adding 6 more panels ( if I can find the same type?) I can create another set with 12 panels that will give me approx. 360v also. What is your view on this?

I have 2 growatt inverter connected in parallel, and 2 5kw Li Batteries. I need to update my solar panels and are reading conflicting messages regarding the setup ( series vs parallel or a combination) What will be the best setup to use? And what number or panels ( total voltage and wattage)

Hello I have 2 Axpert king 5kw inverters running in parallel. The settings on both are the same, however the fans on one runs with the load, slow with low load and fast with higher loads. But the second one runs on full speed all the time, they are both new. Is it something that can be fixed, they are close to our bed room and the noise is irritating. Regards

Thank you, will make the change.

Hi, thank you for the feedback. I must say its a huge relief. Just a follow up question I have Lithium ion pack, should eq be on?

Hi, my inverter is displaying a code I dont know and cant find an explanation of, can someone please help. The inverter is still working 100%

I have the following 2 inverters, Voltx MKS 5 kva and a Mecer SOL -I-AX 5M will it be possible to connect them in parallel?
