Growatt Inverter 5kw Installation And Wiring DIY Solar System!

Elizabeth Keen

What's the brand n name of the transformer

thank

So far, I have installed one 5kva home solar power (must brand),but l still very curious to learn more..

I very much enjoy watching this program, as it is basically my trade.

Playing dumb here but what is the purpose of the Transformer, is this to do 240 appliances? Is it necessary to plug into the system?

You are confusing me, in South Africa, the black is N, red is Phase 1, yellow or white is Phase 2 and blue is Phase 3. We have 230v single phase and 380v three phase. Higher voltage means less current. Growatt delivers 230v single phase inverters here and in the UK. Our cables (wires) are measured in millimeters cross sectional area. I am an Installation Electrician (3 phase) and in our factories you need one of these or you are not legally allowed to do electrical work in the factory.

Pertaining to the grounding: you should install a grounding rod outside the panel but you need to tie it in with the existing ground rod at the main service panel.

I am solar worker your contact?

With that knife switch, a lot of times you can remove the actual internal “guts” of the box allowing you the room to wire them up. Once done you can reattach the internals into the box.
Working on my install today. Enjoyed the videos and information.

Not sure if I missed it or not but what is the purpose of that transformer? You referred to it as a balancing transformer. Thank you.

You mention the AC cables to be the same. Must they be the same length between the 2 inverters going to the distro box

I’m so lost. Geeezzzzz

there are actually 4 nail holes on 5000es

How can i reduce the noise of that growatt inverter. Noise come from the fan in the inverter

ask yourself: if the SPF5000es is connected via AC output and via AC input and the following conditions apply: all consumers are off, the battery is already 100% charged, i.e. fully charged, and there is full sun on the PV modules at 12:00 p.m.: what happens to the EXCESS electricity from the PV system then ? (does it flow back into the public grid via AC output or AC input?) thank you

Newbie question...What is the purpose of the transformer? I've never seen it used on the other bigillion videos I've watched. Is it because most of the videos I've watched are using batteries? Thanks.

Awesome videos
2 questions. Your using 25amp breakers for the transformer with number 8 wire isn’t that awful thick wire for such a low breaker size
And why does growatt suggest a 50 amp breaker in the Manuel for the 5KW but only using #10 wire.
These numbers just don’t make sense to me at all
Keep the great content coming please

um do u have two inverters ? why ?

I liked an subscribed

you diddnt comment on the ground bar if it was put in by you or did it come like that , i got random breakers 40amp and a random panel box 60amp , do you think most breakers are compatible with panel boxes ?

your link for 12 position electrical sub panel does not work , you put in 40 amp breakers you say but yet you have the link for a 30 amp shut off switch

Common protocol would treat black wire as Line 1 (2 wire, blk & wht, 120v) where as the added wire in a 3 wire system (blk, wht & red, 240v), the red ,added wire, would be treated as Line 2.

Good night
I have two sungold hybird inverters installed in a parallel as.master and slave. When ever I manually switch from SBU tO SUB the slave inverter
Switches to error and shut down. It has to be reset manually. Do you have an idea what is causing this problem and what can be done?
Thanks for your help.

What exactly does the transformer do? Does it balance the power coming from the solar system to the grid?

How many panels is recommended to power the 5kva growatt

I got the same wires you use for solar panels i see yu have smaller wires are the wires used for solar panels too big for this ?

can i only connect the inverter to my household grid connection AC- in and Out and not via PV solar connection? Cause my PV cable is on my existing SMA/BYD storage system. Can i charge and discharge the growatt via my fusebox 230v*16A = 3.680w ? (european connection) And does the inverter knows when i have pv excess and charge when i have this excess?

You should always crimp flexible wire, don't use bare copper strands

Hello if you have a 10 kw inverter can you make it by software a 8 kw inverter ????

Hi. Just finished drying walling my shed. I have three Growatt ES5000 with two transformers. Tomorrow I hope to install the backer board (2) to a wall that is ~85” wide. Can you tell what type of screws (or whatever hardware) you used to mount your ES5000’s to the backer board, as well as the transformers. I have Growatt transformers as well. Thank you kindly.

Blessings

Thanks for this video. My question why two smaller inverters instead of one larger one? Thanks

Thanks 👍

HOWdy C-L-E, ...
Whenever landing STRANDED Wire ( especially 8 awg & larger )
FERRULES keep everything together & tight
I landed my CIRCUIT BREAKERS before my FERRULES & CRIMPER arrived
When I removed the Stranded 8 gauge wire from the circuit breakers
I was disappointed with how much they had "loosened" and MASHED out away from the CONTACTS
Same inside my GroWATT INVERTER ... the SOLID COPPER Wires were fine ... but ... the Stranded wires had "lost" their TORQUE
Just an FYI
Thought # 2 ... if it is the least bit HUMID or DAMP ... consider some "NOX-OX" or "OX-GARD" on all your connectors
& the knife edges on your Circuit-Breakers where they slide on your BUS-BARS inside your Circuit Breaker box
& where steel screws into aluminum etc Etc ETC ...
Thanks for sharing your SYSTEM & PLANNING

What is the transformer for

Hi! I’m David Riegel, the guy at the Signature Solar customer pickup. I watched one of your videos (for the first time) last night about your panel installation so meeting you today was a nice surprise. It looks like you are using a Growatt setup. I originally ordered a Growatt but they redirected me to an EG4. The EG4 doesn’t require the transformer, which seemed like an easier install to me. I’m curious why you selected the Growatt over the EG4. Great meeting you in person!

Why do you need a transformer?

You should put the balancing transformer in the main lugs on that panel. You don’t want there to be any chance of that panel being energized without the balancing transformer as that will destroy at least some of the 120V equipment powered from it.

The two breakers on the inverter outputs will protect the balancing transformer from short circuits and it should’ve been sized large enough to protect it from overload in the worst case unbalance that could be predicted.

Why a Transformer, Learning.

transformer for what purpose ? from 240v to 120v ?

So for the brakers that you plug your inverters into I belive you only needed maybe 25amp ones, your inverter outputs 5k watts at 240, so 240volts(x)25amps =6000watts

Was really trying to see the finish setup on the main circuit

SPF 5000 ES( Growatt)
off Grid Solar New Installation
with 12Vx 250Amphrs- connected in series

Why do i get 230 current at solar input terminals
+ points & -side.?
(ACpower) terminals at the inverter.

Becos of this we did not install solar panels to
the Inverter.
System is working on batteries . Fine
earthing is checked
Inverter is earthed.
when its on batteries you can ?? funny
but true
what is the reason for this?

Little puzzled the AC out on the Grow Watt, L1 is Hot or Common, L2 is the Neutral. You connected L2 to the breaker which will create a Dead Short! Neutrals should be landed in your sub panel on the Neutral bar.

comment

yes 30 amp breakers are for the 3000w inverters but the manual says 10awg wire for the 5000 but probably you are right, the manual is really bad

Just FYI/future reference. The smaller box I believe it was a disconnect that you were talking about. If you look at the bottom of it and the top which I believe I could see the Baltimore wrong but they have the ability to be on bolted so you can go through and cut the approximate size length table that you need And I’m bolt the actual fuse holder itself then run your cables through there, hope the wires to it accordingly then feed your excess water back out the top and then both the fuse holder back into its box and you’re good to go. I had to do that with my shop, I ran some cable that was bigger than my thumb and you want to talk about pain in the rear lol we ended up doing that for a couple of the boxes and it worked like a charm. Food for thought all good video and appreciate all the information and the step-by-step instructions on how you did it.

If I understood correctly with that breaker at the very end, this system is working offgrid, and in case you need it you can switch to the main grid ?

Hello how many panles 540w can i put to growatt inverter 5kw es
Can i put 10 panles 540w 2 string in 1 string out.
