Growatt Inverters Parallel Connection

Growatt Inverters Parallel Connection confirmation.
I produced this video initially to share with Growatt and nRuit in China and my installer here in Thailand to confirm that all cable connection were done according to the manual.

Sorry to hear of your difficulties, Paul, but fascinating to follow your mental process through the trace. I wish I could help, but you’re my guru on these matters! Hopefully you’ll share the solution with us shortly.

This is an old video which I had set to private during bug fixing last year. I have had some questions recently about connecting multiple Growatts together, so thought I would make this vid public in case it was useful. I have since purchased a 4th battery and any balancing concerns I had with the batteries have been more than offset by the newly increased capacity.

@@EcoHouseThailand it would be great if you had the time to show that too then.

@@EcoHouseThailand i am planning to do 2 5000es with three 51.2v 200ah batteries. do u have some tips on inverter- batteries cabling and breakers used, thanks

[@timbee71]

Having rewatched this now and compared it to my actual installation, it all looks correct, though my short term memory problems made it an agonising process (Left? Right? Darn, which was it again? 😂). So you mentioned that your batteries weren’t charging in sync or balanced (which was it?). What was the cause of this, and is a hub needed?

[@M-yc3er]

How is the AC wired/paralleled in those sub boards? are each inverter outputs simply tied on the terminal strips(as shown in the manual) or do they all go through their own circuit breaker first, then combine to one main output breaker?

[@merrillbalan]

how is your breaker panel wired Paul? Leg 1 and Leg 2 connection from your 3 inverters single phase?

[@rudibotha3127]

Hallo I saw what you are saying about the 4th battery, I noticed you are using a ethernet cable going from your can port on the inverter to your rj458 port on the battery. Have you tried moving your RJ458 cable from battery to your can port. Then it will be can to can connection.

Hi sir good job

[@robertkerr7675]

Thank you for the video, what are you thought on the growatt invertor you have used and the Nruit batteries are you happy? Did you manage to get the batteries running in parallel?

[@EcoHouseThailand]

As I said in another reply this is an old video during bug fixing last year. I like the growatts I think the problem was that the three batteries were discharging at slightly different rates. I have since bought a 4th battery so I am now up to 36kWh of LFP batteries and have way more capacity than I need most of the time.

Can I parallel 5kw and 6kw both of 48V rating growatt inverters?

[@DoDoBedStory]

can i make 2 inverters with 3 51.2v 200ah batteries?

[@francismartins8511]

Can I parallel 10kva growatt inverter with 5kva growatt inverter?

[@khalilsalam1500]

Thanks for this movie. It helped me a lot. Could you help me to connect 2 Felicity lithium batteries with dip switch and bms setting in the same growatt in the movie

[@rdp9110]

Hi can i ask help...how many zero export needed for 9 inverter connected on parallel...this is 300kwp, 3 phase system

[@rdp9110]

I mean the ct sensors

[@paramaria7085]

you simply should connect all the DC output of the 3 batteries to one bus bar and each of the 3 inverters on the bus bar, that way you avoid different SOC on the 3 batteries. Are your 3 Growatt on one phase or on 3 Phase ? why You use Nruit Batteries? Are they cheap ?

[@EcoHouseThailand]

You can see from the video that the DC output of the batteries are connected to 2 bus Bars - Red and Black for positive and negative. The inverters are connected to each other according to the user manual. The inverters are single phase. nRuit use CATL LFP cells and cost me ฿68,000 for each 9kWh shipped from China to Thailand. I have previously stated : This is an old video (recorded a year ago) which I had set to private during bug fixing last year. I have had some questions about connecting multiple Growatts together, so thought I would make this vid public in case it was useful. The system is has been functioning perfectly for the last year.

[@sainullah4268]

Can those 3 inverters exerts 3phase output?

[@EcoHouseThailand]

The model I purchased is single phase only

[@wcoekaer]

If you mean each inverter its own phase out, yes. I have such a setup at home. 3 inverters set up as 3phase parallel, inverter 1 is L1 inverter2 L2 inverter3 L3 and the 'utility' ac input is similar, I have ac in L1 to inverter1 L2 to 2 and L3 to 3. my set up is 3phase 208v and that seems to work just fine.

[@EcoHouseThailand]

@@wcoekaer My inverters and house electrics are single phase. I want them to act as a single inverter.

[@Uni12355]

@@wcoekaer hi thanks for the video , i just purchased 2 units of Growatt 5000tl hvm-wpv and i unable to get the 3rd for months . i was wondering can use Growatt 5000ES to parallel for 3 phase . If not i need to purchase additional 3 nos of inverter . I am not an electricians and i had almost complete all my wiring and power up , just that i yet to power up output from inverter . L1 , L2 & L3 OUTPUT wil be R,Y,B to the distribution board . So all neutral will connect all together right ? thanks for your advise

[@alanmainwaring1830]

If you are after 3 phase you buy a 3 phase inverter.I am sure they do exist.
