Bro how can I get this board you usually set up your inverter on. The wall of my house is weak.

Check pako market around your location

Alright bro 👍

bassdow:
You evven get idea pass wetin some of us think.
Another thing you should note is, if the total yards required, is close to (half or more than half of) a bundle, it's often cheaper getting a full bundle, than buying in yards.
At end of the day, what matters is, ensuring the workMan buys all he told you He's buying, and doesn't leave with anything.
I don buy wire clip wey I ended up not opening at all due to adjustments that were made later; had to leave it with the customer.

Also before reducing certain things, try to relate with your workMan to understand why it's 50-yards and not 25-yarrds or more or less.

Alright baba. Many thanks.

Good day senior men

Please does anyone here know about this stabilizer? Can it power a 1hp submersible pump?

Thanks for your reply.

Thanks bro for asking this important question.

1. The installation fee covers the solar panel installation and other in-house wiring, breakers, surge protectors, etc.


2. For the load wire, I just got home yesterday and took my measurements. I won’t be needing more than 20 yards. From my main junction box area (starting from the middle of the wall) to the top of the artwork rail (middle of the wall) at the spot where I plan to mount the inverter and battery, I measured 5.5 meters with a tape. Accounting for kinks and other excesses, I believe 10 yards should do ×2; that’s 20 yards. Maybe I should get 25 yards to avoid any blame game.


3. The battery is LVTOPSUN, 51.2V 100Ah, 5kWh. As for whether it’s MCB or MCCB, I’m not sure yet.


4. Regarding the 125A DC breaker, I’ll have to ask him about that too. Are you saying it’s too much or not necessary?



The grid supply is terrible here, so I don’t plan to connect the inverter to the grid at all.

I bought the battery, inverter, solar PV cables, and panels myself.

I’m yet to receive the solar panels........Fouani wahala.

I’ll definitely review the quote with him again and probably bring it down to below ₦300k.

If the DC breaker is between panel and inverter, then its wrong rating. Seeing as u wud most likely connect the panels in series, u sud be doing btw 20 to 25amps max. Ur inverter mppt specs though would help.
@danfreey should be able to help tell if the lvtopsun battery comes with an mcb or mccb, if it does then wont advice having another breaker connected.

Thanks for your reply.

The maximum current draw of a typical 1HP submersible pump is between 6A to 6.5A that is around 1500W. So a correct 5000w AVR should be able to power that

How do you guys calculate this power draw?

For instance charging my battery at 15 amps is pulling about 400w using generator.

Please educate me.

Voltage X current = power

You're using a 24v system, so about 28v charging current X 15 = 420w.

The pump runs on roughly 230v AC, so 230 X ~6.5 = 1500w or so.

Yes.It will.power it.I use this exactly for my 1ho submersible and have no.issues.Mu light is always around 170v and once I pp it shows percentage load as 40% while it boots normally to 220 v without any stress

With a meter you can see power drawn - current, voltage and of course the power.

With a clamp meter you can check the inverter input current, if you measure the voltage the product of the two is the power.

Infact, I pray this troubleshoot works, my SRNE high pv inverter doesn't start charging automatically until I power on a big appliance like a hot plate before it commences charging and even after the battery n when it's full but a few minute cloud cover, it won't restart charging automatically unless I manually power on a big appliance as well

Any updates with this? Hard reset only seems to be a short term fix for me.

Inverter just refuses to charge most of the time. Even doing the heavy load hack doesn't work at times, it just charges for a bit then stops.

another quirk when a system tries doing lots of things. Nothing beats modularity.

Have you got anyOne else using similar inverter and having same or similar issue ? We need know where to start deBugging from.

Person like me go don tire because me can't be lurking around a system like that. it's meant to be Set & Forget, not for me to constantly police it about

It's a temporary fix my brother, so have made it upon myself to always use my hot plate in the morning before it would resume charging... I messaged one of their vendors, i related d issue to him, he read my message n he never replied me let alone render any technical assistance.

I'm also using 3.3kw SRNE inverter, same model with his n it's been worrisome with the charging issue, someone also messaged me on WhatsApp asking me if the issue have been resolved

It's getting annoying at this point, since I hate having to constantly check if my battery is being charged. Effectively defeats the point of having solar.

Looks like this is a model issue, possibly from software. Maybe we should try reaching out to SRNE directly.

Well it was working just fine for like a year before this. I'm also not sure how modularity is a factor here, since this could happen to a standalone charge controller too.

That's what happens when you're just a Seller, and neither a user or technical at all.

With @Edrizz confirming He's experiencing same issue and know someone else having same issue. It kinda means it's either a factory issue (which a software update might fix) , or there's a setting you guys are missing which seems unLikely.

if I were in your shoes, would look for how to spot it in charging mode (very simple if a technician reads the panel) BUT not passing current to the batteries (charging).

Then I have a relay that would temporarily power a dummy load to jump start it. if you ain't experienced in electronics, you could explain this to a technician (locally called RadioNic), He should know how to help you.

Una dey try sha. Even one of my modems wey no get USSD feature (to check data balance or subscribe), despite all it's features, I drop am. When a system, meant to simplify my life begins adding a burden to it, then it's time to let go.

Me could stay over 8-months without nearing any of my Solar systems. Another reason when you guys market Bluetooth this, WiFi that, Monitoring app here and there, I go just dey smile. Wetin I dey monitor ? Na monitor wey I no wan do manually, make me spend money on quality Charge Controller else I for just save the money enjoy the stress

Can you try reducing the absorption voltage a little?

Trippledots, I think you advised on how to resolve a similar issue on PowMr controller. Trying to find your post, but I no see am. Any advise for this bro?

You are right. The current sits at 22A.

A question just occured to me - does this occur when trying to charge via the mains (NEPA / PHCN) or Solar ?

If it's happening via Solar charging, How about relegating the charging to an external charge controller ?

Also does the issue occur at any battery level or mostly when the battery voltage is really low ?

unfortunately, I don't own any Hybrid inverter personally

Seems to be a documented issue. Although I'm on 6.63 not 6.64. I'm pretty confident it's a software thing, otherwise a reset wouldn't have fixed it.

You may be right. I never had this issue when I had bulk charging set to 27.4v. This started a few months after I raised charging voltage to 28.4v because 27.4v was limiting my charging speed.

I don't charge with grid, so I've never tried that. A new CC would be a viable option but I'd rather do all I can to sort this out first.

you know when I don't have said equipment or in contact with it, all I can do is ask questions as that's how we do debugging. It's same thing that happens when a doctor keeps asking you to go for a test, on comming back, He studies the test result, before sending you off to do another test and the cycle continues till He pin-points the issue.

I don't charge with phcn at all, charging depends solely on solar panels only... @HeavenlyBang, did u also notice that LVD has become uneditable, its stuck at 22.6

The whole settings are weird and dynamically change based on what other settings are, I believe.
What firmware are you on?

Have you tried just disconnecting it from all power source for like 5-minutes while also pressing any power button on it to really ensure even the capacitors have nothing in them.

But first Hard Reset it before doing the above.
