If their series voltage is below the controller max input voltage, then yes. But if it's for 12v system, you will be losing a lot of solar energy generated.

Trippledots:
Your monicker looks familiar. You may need to take it to the company. Go through the manual and see if there the list of error codes has this one and gives a reason for it.

Olumighty123:
How do I do this sir?

Dam5reey1:
Get the manual and do settings. I believe this is basic. Or you didnt set anything on the inverter before?

GloryJoyeux:
The error code means battery not connected. See attached photo for error code.

Maybe your BMS is asleep, you can try waking it up by following the steps in the manual and go to option 5 and select lithium wake. (see photos)

You are welcome.

A good habit: always keep the manual of any electronic device you purchase no matter how vastly knowledgeable and capable you feel when it comes to operating that device.

You feared the worst, unfortunately thats what has happened.

Next steps:
1. Get a reputable person to fix the charge controller

2. Get a professional to check your home lightning protection systems and make amendments to prevent reoccurrence.

Remember, the fact that you have used the system for 2 yrs without such incident doesn’t mean there can’t be a first. ‘Mother nature’ is known for not being a respecter of logic sometimes especially when climate change is factored in.

Be happy with the little damage today so you can fix fault points to prevent and even greater damage tomorrow.

Well, it will serve you depending on your loads.

3000w Satchet nverter + powmr cc(old version) = roughly 200k

Solar panels = 600w ( 300w ×2)
= Jinko 440w × 2 = 248k

LifePO4 12v 300k roughly.

Cable : hmmmm used 8core pure copper Ethernet cable.

Output on a good day is 16a to 26a without cable getting hot.

The above is my set up apart from the Jinko and am off-grid with sense ni oo. The most important appliance is the freezer.

So prioritize you load and enjoy free energy.

Dont copy some people here ooo these guys pluck money on trees.

jonescosmos:
I will advice that you don't use the bolded for High Voltage or Current deliveries. Ethernet Cables are not graded for PV Power Transmissions.

Do not endanger your devices by economizing cables.
Yet again, the choice is entirely yours.

GloryJoyeux:
It could mean that your appliances surge current is more than your battery bms can handle, hence the bms is most likely cutting power.

When you clear the error again, can you turn off the pv input breaker without turning on the heavy appliances and observe if the system remains on?

Kindly provide:
1. The specifications of your battery

2. The list of appliances you are trying to run, are they all turned on at the same time?

3. The individual wattages of the appliances

GloryJoyeux:
It works great for you that’s fine. But that doesn’t make it a standard application. Are you ready to take liability for the unforeseen if some you advised to do such goes ahead with it?

There is a reason people go with options of what they can find readily available information on. Options that have now become standard.

Think about it, if you are installing a solar project for a company with ISO certification, can you truly use Ethernet cables for pv current? No you can’t, because there is not enough research to back its use up and it is not a standard material used in solar pv installation.

Nobody is doubting that it works for you, just don’t market the idea of using it. So far, it falls in the experimental and niche category.

Baba sit don for corner.
Endanger wetin?
Do you you even know what am talking about?
Have you seen what am talking about?
3 years old set up.
Please, this is not economizing sir. Na sense bro. Most of you dont think outside the box than to follow set of rules without thinking deep.

Cable that didn't even warm up not to talk of heat up. You will discard your so called regular pv cable upon sight.

Same system that produces 20a from a distance of 78ft to cc at 4string × 2 without heat. Now producing close to 31a at peak on a Sunny day at 24ft at full 8strings ×2 plus different orientation. Na this stage go con cause wahala?

Same cable was used to reconstruct my backup lithium ion ( 48p3s) and got an unbelievable result. Na im won catch fire now? Like most ppu being deceived.

Oh oh wait ooo.
This is not Ikeja or jiji brand new cat5 cable oo. Those ones are worst than flexible wires. They are used imported cables.

Na that your endager and economizing na im cause the above epistle. It was irritating bro.

Reason I always keep my idea.

Baba you still get time + strength on top some kind talk. e be like say as Me go small EXILE, dem come face you

GloryJoyeux:
Nice to hear its up and running. Seeing that you are using tubular I would attribute it to maybe deep instant discharge due to surge of all your appliances booting up at once.

Your batteries most likely cannot instantly sustain the surge current required to start up all your appliances at once.

Now that you are well informed on how to clear the error as well as how to prevent the start up surge, you should have no issues again.

GloryJoyeux:
It looks great. I have also observed that Sigenergy and Dyque product look similar.

While I understand your excitement with you new all in one ESS you must also let others know the disadvantages of such all in one systems.

1. Limited Customisation: if your energy requirements change it may be costly to expand the system ( I can expand the system to 64 kwh if I need to increase storage. Just add batteries?

2. Higher Upfront Costs: Although it saves cost on installation, the higher upfront costs is quite significant (relative to whom or what?)

3. Vendors Lock in: An integrated system means that you are locked into sigenergy ecosystem, limiting compatibility with other brands

4. Maintenance challenges: Repairs are more complicated and most times only the vendor/manufacturer maybe able to repair such.( not any more than with any other premium vendor. Replacement policy)

I personally prefer a modular system with separate components due to customisability, scalability and cost control. Incase of failure, replacement of failure point is easy and cost effective and no vendor lock in. (we all have our preferences)

I also understand that this is ‘premium’ offering for target customers, but, there are also ‘premium’ modular offerings eg EG4, Signature solar, SRNE etc

For avoidance of doubt, all this systems are made in China even the so called ‘premium’ brands. They most likely offer stricter QC testings hence should last longer between faults. Then again, even premium brands suffer from QC issues.

*pls excuse any typo, I didn’t proof read this.

What is Ethernet cable made of?
What are pv cables made of?

I am not an installer.
I am a diy dat think outside a box. Simple!
Lastly, it is for me and me only.

My idea to myself.

So long you don't reason like them, you ain't a professional. ma own be say - do what works for you and after thorough successful testing, you could apply same for clients.

Though me ma never attempt such, BUT wouldn't careLessly doubt you so long it works for you. Some things seems undo-able if you don't push limits.

na that limit wey make my 32-inch LED monitor spoil. I recall burning a brand new lapTop PC of less than 1-month YET today, I'm enjoying the result of the experiment.
Actually damaged 2 laptops, 1 had charging issue, while the other burnt it's motherboard yet I didn't giveUp.

Currently enjoying running my Core i7 and Core i5 PC + 24-inch LCD monitor (the 32-inch went bad) + FANs all on 12-volts.

Even external Tv antennae sef dey run on USB which is 5v.

And I've been doing this for over 5-years. Tomorrow, person go wan come argue with Me. Even if na God sef, I no go gree.

I even wan tamper with my submersible pumping machine but when I remember cost of a NEW one, I kinda respect mySelf; or mayBe na because I no too get time like before
