8kw Deye Inverter Setup | Is it any Good ?

[@ElecAndAll]

What are your thoughts on this setup ?

[@zrk5487]

I'm gettin a 8kw inverter, 14 x 550w panels & 2 x 5kw batteries. House of 7 people including running a business with 3 employees (office work). Connecting everything except stove and oven. Geyser is solar, but i will supplement with this. What do you think? House is 400m2 in size.

[@ElecAndAll]

Looks well spec'd. Let me know how it performs.

[@muzzammildikko567]

The battery capacity is too small for the setup, not with for night time back up

[@tokunboogunkolade1687]

@@muzzammildikko567 I think so too

[@zrk5487]

Actually it runs perfectly, even now in winter. I deplete the batteries to 30%, but it's usually fully charged by 11am. Summer would be even better. We've changed habits slightly, so tumble dryer and 2 x geyser heating is mainly done around midday, which takes us through the evening now in winter Perhaps an extra battery may help only in winter when there's really no sun. But honestly, that only happens less than 10 days a year. So ultimately happy with the setup

[@Din2580]

On semi-cloudy days you'd wish you had more panels. Over paneling isn't a bad thing and having backup battery power available for at least 3 days without the sun is also nice-to-haves which will become ideal if you want to go completely off-grid.

[@aadil558]

Have a 5kWh deye + 5kWh LI battery + 8 x 450w panels. No issues so far and more than sufficient in running the home during loadshedding (have a gas stove and geyser, oven and poolpump not connected to the solar). Battery depletes to around 60% after 4 hour loadshedding.

[@ElecAndAll]

Great. Well specc'd

[@chiragtilva8116]

How long have you had it? Has it broken down during that time and have you needed any service?

[@ElecAndAll]

@chiragtilva8116 still running. This is not my installation though

[@tirivaenim]

Deye & Sunsynk is the same hardware, the software is different. What huge loads do they have so they can use them, moreso during the day. In winter or rainy months, they’ll not need to worry about Loadshedding. Is the house split to Essentials & non-essentials?

[@ThePonderi]

It's a good system. In winter they will have enough power

[@Mylifelovingit]

5kw luxpower. 10 x 580W pannels in 2 strings east west because i have no north facing roof. Plus 2 4.8 dyness batteries

[@ElecAndAll]

Nice... U have mini power station there 😉

[@devinfraserashpole4753]

It is interesting that the system is feeding into the grid. Most municipalities do not allow this as far as I know.

[@ElecAndAll]

They don't, but they won't refuse free generation capacity

[@devinfraserashpole4753]

@@ElecAndAllI’ve heard that some meters see the export as an import so it actually charges you.

[@ElecAndAll]

Correct. The Landis Gyr measures what is exported. But it doesn't charge since eskom requires 3 separately identified readings as I mention my in my video.

[@devinfraserashpole4753]

@@ElecAndAll I understand. I made a spelling error in my last comment. Thank you for the explanation.

[@llewelynklaase7896]

would you need to split circuits if you have this 8kW inverter?

[@ElecAndAll]

Depends on your electrician and what loads you have.

[@johanbester4484]

Interesting the comment on that this system is oversized. Question...what is yhe kw/h usage per day and what appliances is connected. I have a 8kva Deye inverter and all appliances is connected...even the 200l geyeser with a smart switch. Have 8 x 550w pannels on a string with 2 strings connected to each mppt.

[@ElecAndAll]

Hallo Johan. Ja, I mean the PV is oversized as 80% of the time the system isn't utilising the full PV capacity. What they should do is increase the battery bank so that they maximise their PV.

[@SKL733]

Is it noisy? I'm planning to install a similar Inverter inside the house, under the stairs.. Thank you!

[@ElecAndAll]

Yeah it does get noisy. Needs ventilation too

[@dannystrachan475]

The 5kw Deye has a huge heatsink and has only 1 fan the comes on when pushed really hard. The entire back is a heatsink and does a really good job. You can hear the fan but it is not loud enough to be annoying and very seldom comes on.

[@muzzammildikko567]

I have a 5kW Deye with 365W X 9 and 550W X 5 panels with 14.3kWh X 2 batteries. Total PV is 6.035kW Total battery is 28.6kWh though i limit usage to not more than 25kWh.

[@ElecAndAll]

Why such a large storage bank?

​@chiragtilva8116 I've had the setup for about 18months now with no issues. The batteries are Eve DIY lithium i put together myself.

I have an 8kw Ouco inverter with 12 x 540w mono panels & one 5.1kw lithium battery. Are you familiar with this Ouco brand inverter.?

[@ElecAndAll]

السلام عليكم Yunus I know that in NX it is popular. I haven't heard of it but it could be a white labeled Chinese make. Tell me more about it, is it an off grid or grid tied? Does the chassis looking like the Deye?

[@yunusally8993]

My solar system is not performing too well on a hot day as well at the moment according to the app & I have complained to my installer about this. I am also not sure if it's an Ouco inverter setting configeration issue or a solar problem here. Can you send me your email address so that I can send you more info on my inverter solar app.

[@ElecAndAll]

Could be that the voltage from the panels are in excess of the maximum input voltage of the inverter. Or the panels are heating up. Sounds like the former. Leave your email with me and I'll contact you.

[@yunusally8993]

@@ElecAndAll Yes similar to the Deye inverter. Mppt input voltage 120-500V. This afternoon the inverter just shuts down at a number or intervals & after a few minutes it comes back on again but there was grid power. This inverter I purchased from ARB Electrical & Solarmatic Energy did the 12 panels installation to the inverter only.

[@ElecAndAll]

Sounds like the inverter can't handle the voltage

[@yonas3792]

2*100AH ?? I didn’t get it

[@ElecAndAll]

OK.

[@hussaindewan9365]

We’re not allowed to export to the grid at the moment.

[@ElecAndAll]

We can but, you won't be reimbursed.

[@ClaudeFeller]

8 kW hybrid is the least reliable model. We stick with the 5 kW single phase and the 10 kW three phases

[@ElecAndAll]

What was your experience with the 8kw model?

[@ClaudeFeller]

Tricky to get the right firmware. Didn't work in parallel

[@xgrapher]

running a smaller engine on full throttle kills the car faster whereas running a bigger engine with only 10% throttle makes everything smooth and long lasting

[@ElecAndAll]

An inverter ain’t a car.

[@kevinmax101]

​@ElecAndAll Exactly lmao. If his statemEnt was anywhere remotely true, Voltage.Transformers that convert grid power voltages would all die within 2 years lmao. Mechanical is different with electrical. As long as your Capacity is correct, it will last. Oversizing in electrical is usually to avoid overloading events from damage due to excess cyrrent/voltage due to non-normal events.

[@xgrapher]

@@kevinmax101 you’re a Filipino. A mosfet of peek 100a should not be used for more than 20a of continuous use. High ampere is high heat. Are you going to teach me about electronics? What have you built so far? Lemme guess just plain bs. I have made many things in both mechanical electrical electronics software hardware you name it so back off buddy
