Good day all
Please is using breaker for solar input enough to protect this controller? I intend to use the normal cut out fuse after breaker, to manually remove when its about to rain. Will this idea work? Panels are in series, so maximum current input cant be higher than 15amps.
Please what is the simplest way to protect the controller from damage and how have you guys using it here been able to protect it for long from damage. Thanks for your reply

Does your building have lightning arrestor? If yes, how about earth? If yes, just use a DC breaker.

HeavenlyBang:
That sounds awful wtf.

With enough PV you'd easily hit that score to get back to business.

I also noticed that my growatt 6kva inverter using a (cworth 15kwh battery) when the battery reaches the shut off voltage/percentage of 20% and the inverter stops discharging at night.. By morning when the sun comes on and it starts charging the inverter doesn't automatically come back on and it displays error 4

My questions;

Is this normal?? Isnt the inverter supposed to automatically come back on when there is sunlight and it starts charging?

Is there a particular battery percentage it has to reach before it comes back on??


Someone please help!

Usually the inverter won't provide output until the battery charges to a certain percentage (,usually 20 to 30% SOC)..But the inverter will charge the battery via PV but will not provide any AC output voltage unless there's NEPA supply.

Can this be used with Gospower? How much is it and where can i get?

You can always buy their product (software or hardware) from their site. One of my earlier screenshots captured it or just google it. Prices is from $59 for software and $169 to $209 for device and software.

I doubt if it can be used as I don't think it's neither Axpert nor Voltronic inverter.

But to be sure you can always contact solar assistant by sending them a mail with your inverter specification and pictures. Especially pictures showing the communication ports.

Email: info @ solar-assistant. io


FYI: Gospower doesn't know what Solar Assistant or HA means (check attached screenshot).

ManAdii:
Have your tested TBB sir?
I'm not sure deye solar assistant can beat theirs

It is not just for Deye but many other types of inverters.

And no, I haven't seen TBB remote monitoring software. I'm more of a DIY person so I like things that can work for many inverters not just one particular type of make.

temi4fash:
PLease how we get to use the Solar Assistant with our Inverter?

Do i need to buy a different module aside the one from Growatt?

1) Raspberry Pi
2) Install Solar Assistant inside Raspberry Pi
3) Buy the software.


Or buy the device (raspberry pi with software) if you no dey like stress/DIY

CuteMaro:
Please guys where is the telegram link to this awesome thread?

If there is one, many will miss out on the fun.

GloryJoyeux:
Hi,

I believe these are not real time figures, most times there is a 5 minutes refresh delay. And sometimes it doesn’t refresh all the figures. So it probably didn’t refresh either the pv or the battery charging figure.

You can try refreshing again in 5 mins, alternatively, you can confirm physically from growatt inverter.

This is why solar assistant has an edge, it provides live monitoring information and not at 5 mins intervals like most inverters do.

I can confirm Solar Assistant's speed and superior real-time edge capabilities compared to other monitoring solutions.

BiigTee:
Who can please tell me why the ppv generated and the charging power are yards apart on this growatt inverter?

Conversion losses + your load = PV generated.

Also I wonder if what you see is in real time. That is your load consumption and battery charging power whether there is no lag.

Funny enough it's SON Label, it's the Chinese Label that carry 280AH

This our SON na prodigal SON

Dam5reey1:
Glad it worked out!!

Knowledge sharing is on our vision..

So here is the Concluding part of the Haisic 4 19WH 12V Capacity test


https://www.youtube.com/watch?v=8cSSjUeU_CE?si=cDppLjQY0bGOsuDq

At best this is a 3.7kwh so the 12v 280ah checks out. The 4kwh on the label is just the typical over inflation of capacity which most Chinese brands love to do.

Still impressed though.

Trippledots:
It's a contactor with 2 normally open and 2 normally close connections. Grid goes to the coil, and also to the normally open contactor input. Inverter output goes to the normally closed input.

The normally open and normally closed outputs are interconnected and goes as the final output

How it works:
When there is power supply, the contactor energizes and closes the normally open contacts sending power out from NEPA.

Once Nepa goes off, contactor is de-activated and swings back to the normally closed position, sending power out from the inverter... I have a surge protector that helps with voltage fluctuations and also my stab has a delay timer that helps the overall function of the contactor.

Thanks for the detailed explanation. Whenever you have time help with a sketch of this connection. Nothing fancy, just a sketch showing these connections. Danke.

Trippledots:
Some relays and contactors accept direct grid voltage and work with it.

I recently rigged up one contactor to use at home (attached) as an ATS, and it works very well.

Cc numericalguy

Please can you share a sketch of this connection with this contactor on how it works as an ATS?

chris81964:
Yes it is. We have been doing this for years.

I like this. Getting the soil wet for lower resistivity is easier with this technique.

Hello Dr Solar, that thing at the centre of the pipe that I'm seeing is it the earth rod?

Using pipe is a cool way of running earth. I even saw one, at one flow station, where the pipe is galvanised steel.

ola12:
Thanks. I'll rather go for a 1kva as I just need something strictly on a budget which'll do the job of supplementing my grid/replace it on off nepa days for powering my laptop+fan.
I was going for this one specifically but no felicity dealer has it in stock, if someone knows why or has used it with reviews please let me know.

If there're other really trusted 1kva 12v hybrid inverters I can get instead I'll appreciate the information

I have none. Try Welion

HeavenlyBang:
The last lead acid 12v 7ah I bought from Jumia didn't even last two months before it stopped powering the fan for up to an hour.

Decided to never buy a lead acid replacement again.

I don't expect this to actually be 9.8aH, but even at 6aH or so I'd be satisfied.

That LA small size battery has horrible lifespan. Especially when you buy off brand. Branded type is often too expensive for an LA battery.

HeavenlyBang:
Replacement battery for rechargeable fan. 14.8v 9.8aH li-ion.

Will provide updates if/when I receive it.

Bought a lead acid 7ah last week for ₦16,500. This would've made a better alternative. Assuming paper specs match real world spec

ola12:
What's the most reliable/best 12v 1kva inverter brand to go for?
I was thinking of felicity 1kva 12v but haven't found it anywhere in Nigeria

Felicity has it in 1.5kva 12v.

Chimarto:
I Will stop SMS alert and enable email alert, we are losing a lot in this country,

Email alert is not as fast as SMS o

Good to see after 2000 pages we still have the Lead Acid vs Lithium "war". Interesting

Dam5reey1:
I dey buy the one my power reach, Will do Haisic soon

Drop video when you do. Thanks for all the work you do.

Dam5reey1:
Hmmm..
Most of them can't send me products to test..

Take one for the team, buy

dollarnaira:
Super true.
While some will need 5 Pv to achieve their aims another will just need just 2 pvs to achieve same energy.

That's the sad truth

abuzz33:
With a roof with that kind of steep tilt I wonder just how much power you lose considering Nigeria is between 6-9 degrees north of the equator. Has anyone investigated this? I have a couple of solar flood lights and noticed that tilting the panel at 45 degrees reduces power capture by at least 20%. Placing it completely horizontal captures the most power.

It is hard to change the tilt angle without a commensurate roof mount that allows for the appropriate tilt. This is one of the most overlooked aspects of renewable energy installations. Nigerians often prefer extremely large tilt angles on their roofs, especially in so-called "modern" architecture.

A lot of power is lost this way. Most of the time, you have to add more PV panels to offset these losses.

MilesLamar:
Good morning guys

I ordered a nillkin case on aliexpress since 21st April 2025, till this very day it's hasn't been shipped.. What's the way forward?

Buy in Alibaba and use third party shipper.

Luminous 24v/1.5KVA
This is the type of inverter that i have and I have been using it for 8 years

This inverter doesn't die.

My cousin has one since 2015. Still rocking.

Ahyjo:
please I need a reliable plug here to get these and a good dc cable from.

@linnov8 sells good DC cable and breakers

With all the wealth of info made available here, you are still saying you dont have money for lithium. How much do you know will get you 2 nos of 12v tubular batteries for your 24v system? (Nerver forget you will use it at 50% DOD, let me not even talk about charge and discharge rate) And how much is 24v 100ah lifepo4 battery?

Some peeps may not like lifepo4. This used to be 8 years ago.

Alueheal:
Please who can recommend a good 2.5 KVA Inverter 24v and a good tubular battery brand..
I don't have money for lithium battery please take note. Thanks

Luminous inverter

Luminous Tubular Battery.

Cheers.

Ahyjo:
Please I need guidance on the breakers I need to ensure are used for a 6kw pv and 6kva inverter setup

You'll need

1) a good earth
2) a DC SPD
3( an AC input breaker ~ 32A
4) an AC output breaker ~ 20A
5) a DC breaker 600V/1000v (the amperage will be determined by the configuration of the PV with respect to the Isc)

Dam5reey1:
60A..1000w 18-100V MPPT VOC 125..
I will be testing it with 2 units of 590w panels

That sounds impressive. Update when you finish testing.
