Incase u get one locally, let me know, it cost around 8.5$ for 5a on Alibaba but the wait time is 2weeks plus

Okay boss.

I bought a rated 5.5 KVA 24v to serve a very unique need. It is not hybrid and seems light in weight for the said capacity. I wanted an inverter to carry my ACsx2 plus other domestic load during festivities when the whole house is full and there are many things going on at the same time. Obviously that will include fridge, washing machine and 1HP pumping machine. It has served the purpose well with no issues. I also use it a few times to charge my system with the national grid as I found it less sensitive to voltage fluctuations. ( I use a Servo stabilizer before inputting to the inverter)
For my regular use I have a 3.5kva 24v Foresolar inverter. Can carry fridge and washing machine but NOT the pumping machine with other loads.

adibo:


Good morning. Pls, how many kva did you buy? Also, is it hybrid or the normal one? Lastly, do you know if it can take fridge and washing machine?

Myself50:


Something like this

The first picture is a RCBO right

I have 8 300w s for my 48v system but my charge controller rarely reads above 400w. What connection should I do for the s?

What charge controller do you have?
How are your s stringed and connected?
What is the state of your battery when you wake up in the morning?
Do you use NEPA to charge your batteries?

A yield of 400W from a 2400W array is terrible. But, it may be perfectly normal if your battery is usually charged with NEPA and is full most of the time.

Whats the total wattage of your solar s ?

Can an mppt charge controller output more amps than the connected solar s can provide?. Like a charge contoller outputing 60amps from a 40amps or 30amps solar setup??

What charge controller do you have? Felicity mppt 80a

How are your s stringed and connected? The formal installer did 2 series to 4 parallel but I just changed it to 4 series to 2 parallel

What is the state of your battery when you wake up in the morning? Usually dead

Do you use NEPA to charge your batteries? Yes when there is light but when there is no light and sun is shining bright it will still die

No one here seems to mention the smart series of charge controllers from Demuda. Their charge controllers look very decent plus they are smart, have lithium profile and can be connected remotely via their app and the possibility of iOT I'd like to think.

I presently use one of their small PWM and I am presently expecting a 60A MPPT.

Abeg mak una help me put mouth 😔

Hi everyone.
What type of charge controller will be best to use for 5* 350w solar s on a 24v system (2 220ah tubular batteries) charge controller should be 120k or below (in price) and also the ideal connection should be discussed

Also what brand of inverter will be suggested (min 2kva)
Thanks.

Or if i go for the 80a mppt CC on the SMS sunmate Hybrid inverter i used for my previous installation. Will that be enough to handle the job?

zeestone99:


Honestly can't say. I have not reviewed or used them personally. The batteries are really cheap and i doubt it is of good quality or complete spec.

I’ll stay away from them then

What could be the issue here
I noticed whenever I'm on inverter and I'm using my phone while plugged in, the phone touch start malfunctioning, even my laptop trackpad and touch also malfunction when plugged in on inverter.. this doesn't happen on gen or NEPA.
Abeg who don experience this thing b4

PS:
I just noticed if i turn off extension socket, the socket light doesn't go off totally until i unplug the socket

what kind of inverter are u using?

Sms sunmate 2kva

brightk:

Sms sunmate 2kva

hmmm. Was it liie this the first day u installed?. There might be issues on your inverter

1) 255wx6 Mono s as 3s2P + 60amps Epever MPPT Cc
2) 180wx3 Poly s in 3s +60 amps Powmr MPPT Cc
3) 100wx5 Thin film s in 5p+30amp Epever MPPT Cc
Connected to @15kwh of LiPO4 batteries

Start by checking your neutral connection.

Do you use the same socket for your equipment when on Nepa or inverter or do you have a seperate setup for your inverter? If a seperate setup check your connections and earthing. There is a bridge of wire somewhere.

Most likely culprit

It's same setup
I didn't do load selection or anything like that

It's a one week old installation,

Possible!

Charge Controller can output 50v @ 60A if Solar s gives 75v @ 40Amps.

Same power.

HAS anyone patronised techland. I got the here on this thread a long time ago but because no recommendations i didnt use them

Sounds like you do have a serious issue then. All these answers checked out well. You should certainly get more than what you are getting. You need someone truly knowledgeable to help you review the installation. One other quick thing that you can check is if your Charge controller is set to limit the charging current.

olopan:
A lightning arrestor or trident install at the highest point on a property to be protected with a very low path of resistance to the ground.

This is to allow for a point where lightning can go instead of through your house as that one nah fire or die sef

Ideally, PV shouldn't but if it is grounded, with no lightning arrestor close by, it could be an attractor of lightning at times.

Does it mean it's better not to ground it if there's no arrestor close by?

kristien4:
the earliest I've checked it is 8am in the morning...and it started charging, tho with about 500watts from the pv.

okay

.
10kwh 48v Felicity lithium battery #1,950,000 and 10kwh 51.2v Felicity lithium battery #2,200,000.
Please what's the different between 48v and 51.2v in connection to the price difference of 250k?

You dey ask good questions shall oh. Maybe one original the other

ewizard1:

No comment about the rest but Sorotec: a big NO. Gennex will outlast the Sorotec by far under the same condition

lolz, I no sabi wetin sorotec do una. i have 4 sites with sorotec, with oldest going on 4yrs now...zero issues..maybe its the models you bought. i bought the mid range models back then 3 units of revo ii...the one with touchscreen and 1 unit revo E, all firing strong. the revo E sometimes has the float bug...other than that my experience with sorotec is great.

which models give una problem?

They are cool. You can do business with 'em.

House, please I need a 3.65V charger for top balancing of my lifepo4 cells. Any idea where I can get one?

There is a seller here that sells variable output voltage charger here, Valto. https://nairaland.unblockandhide.com/390522/solar-energy-complement-fta/1131#110684591

But if you don't like the charger due to cost or availability, you can buy a normal charger and get a variable DC to DC buck converter like this type from Konga with image attached below that can take a DC input (say a normal 12v charger's output) as input with variable DC output with you can use to do top balancing

Anybody has an idea of the cost of installing thunder arrestor. I think I need one
