In his use case he has no need for smart inverter. He's good and better off with his 5kva inverter because he ont uses it at night and with his load, there's no way he'll ever get near low voltage. All he needs is a charge controller.

I've been using your lithium in a place for clocking 2 years with an old inverter and an external cc handles changing. From night to morning we never get even to 70% soc by morning.
If in worse scenario it happens that it gets low, the BMS has been set to cut off battery and, of course inverter, at a safe specific voltage.

You don't need a new smart inverter. All you need is anything reliable that can invert pure sine wave for you and you can work with LFP. That's if you know what you doing.

isn't it dangerous to assume He never would get close to Low Voltage.

See eh, there are things i can do myself, which I wouldn't do for a client.
reason being I know what i'm doing; they don't even when you tell them.

Let's just hope the BMS does it's work. The kinda products wey full market this days, person really need have multiple defenses

Mrreed:
Press and hold the function button, you should be able to adjust your charging voltage and cutoff from there.

Hopefully this helps him BUT I have learnt some powMr products are repackaged versions of other products hence I try not to assume unnecessarily

Royle2014:
What do u think about this charge controller. Its 185k for 60am pv max is 200v... Has Bluetooth functionality to monitor stuff via your phone and can set lithium parameters allegedly or can u recommend something even cheaper but still good? Ktech charge controller

This is super expensive if you ask me

Also, would suggest you ignore unnecessary features, and focus on actual features. Don't let secondary features such as Bluetooth functionality distract you.

and that brand isn't even known to me at all.

If you're in Lagos / Ogun state, I fit help you with a lightly used one

Royle2014:
Unfortunately this one doesn't. Had to connect to battery terminal and turn it on just to show u.

I have checked d manual both online and offline but no secret menu

I can bet all I have that this thing I’m seeing has a menu for you to select different voltage range for your battery type (except there is none for Lithium). Except if those buttons, which you can also find in editable controllers, are just there for fancy.

I know that BUT like I once said, there are people to whom basic tasks such as this is a big deal. myself rarely need consult manual even for products I haven't seen before. I just fiddle my way to success.

You are right. I was once like that too, that is why it’s good to take one’s time and go through the manuals.

Taking a closer look at this image again, the funny thing is that the instruction on how to select your battery type and all that are boldly written on the right-hand side of the inverter. Damn!
😂😂😂😂😂

I wish i can upload a video. Theres no option for Lithium. And no option for "user" to set their own parameters. I'm not a dull person, it's crazy y'all would think that. For the engineer to advise me to get a smart inverter, he tried to enter menu to pick self parameters but no such options exist on this inverter

Felicity 80A cc is about180k.

Thank you. I'll avoid this one then. Thank God i I haven’t paid for it. Its a pay on delivery Jumia order

I dey Delta o. Nor mind pay for waybill if u get cheaper used one wey make sense for sale.

Don’t get me wrong Bro. I will never call anyone here a dull person, and sorry you took it that way. It was just an observation that I felt that you and many of us who are trying to help may not have spotted from the pics.

If I were in your shoes though, I’ll jejely get myself a separate Charge controller to charge my battery since you don’t ever need grid charging; and let the inverter do its main job.

My issue with wayBills be say what if story go enter am. either way, if you're out of options, kindly do get in touch BUT first, ask here should in case anyOne closer to you got any for sale.

Just ensure it's got the feature you're after before making payment. If out of luck, then you could get in touch and yea, they're cheaper though depends BUT they've got no Bluetooth feature.

Check 80a Felicity max voc o. The one I AV here is 135v

Is yours the new model? The one I have is 145v VOC

Use your property like that. Is it not working?

Solar installer needed in PH. please dm.

All items ready for delivery to Abuja..

Not yet o I’m just deliberately lagging because of light has improved tremendously in my arear .

Ok i want to reach out to you personally should ibdrop my digit or you drop yours

Yh. Sorry. It's 130v.

Obviously there is an ongoing change in climate. This is no longer wet season.

How do you deal with lightning please?

In April I connected DC phone chargers to charge controller load output section. One sudden lightning strike just before windy rain started blew all the chargers.

( Charge controller DC out - DC/DC buck converter - mobile chargers)

I thought my DC-DC buck converter could stop excess current if there's surge, .. for where? Lightning flew through it and the chargers bought out smoke in my front

Do you earth the charge controller output before passing to your devices?

Thanks for your anticipated response

Supply pictures of the controller and chargers. Also details like brand and max pv input.

Can you send the picture? I have a 5KVA Yohako inverter (Non Hybrid) but the settings are editable. I suspect yours is the same type.
Does it have a screen and four buttons?
Don't sell off before you confirm this o!

Royle2014:
So guys. I've had a 5kva Yohako non hybrid inverter i bought back then for an installation but i never used. Now i have a 10kwh lithium battery and i want to install it. However, an engineer told me that i need to get a smart hybrid inverter because installing my non hybrid yohako inverter would ruin my lithium battery because it's not smart and wont be able to set cut off voltage etc... He's suggesting that he can help me sell off my 5kva 48v Yohako, I'll add like 100k (amount to buy a stand alone charge controller) and he'll get me a smart inverter of 3.5kva or 4.3kva for 350k....so he plans on selling a 5kva brand new Yohako for 250k. The whole thing sounds fishy to me....is he telling the truth or can i go ahead and use the Yohako 5kva with the 10kwh lithium i have?. I already have 4 590watts panels, all i need to do is to order a charge controller and do the install. I dont plan to charge with grid fyi.... Strictly solar charging

All in one view.

Pls note DC buck converter is not connected, the wire goes elsewhere. I just placed it on top of the CC

Good evening Hux...

I've a 5kva Syndian Inverter with 8 luminous tubular batteries which powers all my appliances like 1.5hp Lg inverter, 65 inch Lg TV, Blender, Thermocool Hiscene Table Refrigerator, 4 fans and lightning points. I bought my inverter under good working condition but as fairly used, and it has served me for 3 years now.



This is the 3rd time I've repaired my inverter and just one week of using it after it was repaired, I noticed the fault as started again. The inverter will be making a humming sound inside it and the load rating on the inverter will be like 13% to 14% when my appliance is switched on and even when I switched off all the loads.




Why is my inverter making humming sound and why is the load rating 13% or 14% even when there is no load on the inverter? Is it normal?

Just what I thought earlier - not sure it's Lightning / thunder. what you connected probably didn't match it's source. Thar Car phone charger is usually 12-volts though I don't know it's exact rating.

Since we don't know exactly what was connected and how they were connected, can't really say much. Normally, Lightning would damage your charge controller.

I presume your battery system is 12v

if using an inverter already, using that Car charger wouldn't save you much hence a waste of resources

This is it

Valto:
buy a single burner toks halogen electric cooker(consumes max 1600w), minimise other house loads when using the cooker. your inverter can comfortably carry load lesser than 3kw..cheers.

Do not try this so called halogen cooker, instead just go for a recent or for foreign used induction cooker with low watts another benefit is that the consumption rate can be adjusted

Battery is 12v

I've been using the chargers for long before the incident, it was lightning.

I'm now using USB charging modules sha

Inverter spoil twice before. Third time two electricians said they can't fix it so I abandoned it with them.

That's why I decided to ditch AC and be using DC for charging
