EduTechTainMent:


What exactly do you wish to learn. I shared some pics of my setup earlier on in the thread. It's simple really.

The dc cable from the cc goes into a dc breaker. The output dc cable from the dc breaker goes into the central connection of the Swiss knife change over. Finally each end of the change over has a dc cable connected to different batteries. So u just switch the change over from one battery to the 9ther depending on which you need to charge with the s.

How do I now run the inverter side ?

Used Trina 250w poly solar for sales,just offloaded,

If you're buying more from 4 pieces #32,000

If you're buying one or two pieces #35,000

Good evening house. I am experiencing an electric shock at the sides of my freezers when using welion inverter. If I switch to my srne inverter, the shock will stop.
Who has experienced this before? Please how do I solve this problem?

Confirm the welion for psw or msw.

Confirm the welion for psw or msw.

How can I confirm this

It is the popular 4.2kw welion inverter being sold here. I bought it from a dealer on this thread

Can this new version be paralleled with with the SUN-5K-SG03LP1-EU model?

jonescosmos:
Hahahaha, The AM2 models has got absolutely nothing to do with Naija. I also stumbled on a thread where someone said AM=African Market.

Here is Deye Model Number Coding for those who cares to know.

SUN - Product line

3K, 5K, 10K, etc - capacity

SG - Hybrid models. Grid tied are G0

01, 02, 03, 04, 05 - Release version (Compact Version & Big Version for client to choose according to space available for installation)

L, H - LV/HV battery

P1,2,3 - the number of phases. 1 - Single Phase, 2 means US Split Phase, 3-phase

EU, US - Region

A - 5-29kw

B - 29.5-50kW

E - 60-80kWh

S - Lock catch case (?)

M - MPPT

1/2/3/4 - Number of MPPT

-P ? (Some have extra P on the end and there has not been any official statement to clarify what it denotes).

Turn on a regular fan( not rechargeable) and listen to a humming sound possibility.

Are your equipment connected to earth

Obnoxious2001:

No. But the inverter itself is connected to earth. And the spds too

Please can you share their location

No single phase has 4mppts, you can get 4 mppt and above on HV models.
Grab Deye brochure here:

Capacities are the same, protections has been improved, newer models have more surge tolerance, casings have been redesigned, colored screens have been introduced.

It's always advised to go for new models in every invention.

mangolpupa:


Bros is there a single phase Deye that has 4 mppt (8kw to 16kw).

Had you had the privilege of contrasting between the old & new model Deye (say 12kw or 16kw models). Is there any feature, improved build or construction that should make one be advised to go for the newer model.

Looking forward to your insight.

You must parallel same versions and models. The SUN-5K-SG03LP1-EU model must be paralleled with another SUN-5K-SG03LP1-EU model and their firmware versions must be the same too.

Ferdiwar:
Can this new version be paralleled with with the SUN-5K-SG03LP1-EU model?

Good afternoon Beautiful people. I recently got tired of Nepa ish and decided to get a solar system for my small home. 1 freezer, 1 console, 1 TV, 2 fans. I ed someone who after talking to him we agreed on 4kva which he said will carry my non inverter 1 hp Hisense AC. We agreed on 1.8 and he'll be using 400w s x 4. I want to know if it's a good deal on my part or if the s is not enough for that. He sent me some tubular batteries which I'll post below. I'm just new to this and don't want to get burnt. Country hard

Its good that you are here. You already saw the reactions of my people. See u can get something better with ur N1.8m or with just small addition. Now let's recommend solution:
1. Where is ur location?
2. You could go for 2kw s, 4.2kw Welion inverter, Valto 3.5kw LFP, protective devices, installation. If na me be u, if I go for this, I will ditch the a/c and go for Qasa 18' standing fan jeje de enjoy my life. Tinubu no send anybody o. All d best

Good morning and happy new month

Please is there a way i can reduce the voltage from pv from say around 100 - 90v to say around 70v (to the limit of my controller)?. Is there a dc to dc buck converter that is readily available that can do this?

Thanks for your response. If you have it available for sale please indicate or if you know where i can shop for one online (preferably locally), please kindly show me. Thanks

Thank you

dollarnaira:
Jinko 585w now available

400w available?

SolomonGrundy:
400w available?

No

Dam5reey1:
So Main Take away for the Deye inverter is that there is no Feed into Grid feature. Which is what Make Hybrid inverter, this is OFF Grid. No CT and all of those.

But still have Smart load and all the deye Goodies..
We dont need or even use Feed into Grid, so smart way to reduce it cost and make it more affordable.

In essence made for Nigeria

I was able to the installation manual here as no info on Deye website.

https://www.solar-europe.co.za/product/deye-6kw-single-phase-off-grid-hybrid-inverter-voc-500v-battery-60v-excl-wifi-sun-6k-og01lp1-eu-am2/

As per you comments on CT and grid feed, see page 38. Maybe I am not reading it right but it seems to indicate in certain configurations it can feed to grid and there is an internal CT with option for external.

Looks like a very interesting inverter, I particularly like the overing capability!

Different specifications everywhere, make I go get the Booklet manual.

Please what are the precautions that can be taken to avoid lightening damaging the solar s and system. The building is an old apartment built in festac in the 70s.

Please, Is there a wifi dongle that works with Gospower 6kw hybrid inverter for remote monitoring?
