There is a difference between made for Africa TVs and made for Europe TVs, the TVs sold in our local stores are made for Africa

Wahala! Wahala!! Wahala!!!



I cover my TV with the blood of Jesus ooo...

But do you have a personal experience with a particular Hisense model? Please share, for our learnings

Oshomo12:
Pls clarify this statement, I don't understand it, thank you.

Note: 1hp is 750 w. so 1.5hp should be 1,125 w.

Golgota:
It depends on the make of the pumping machine. My 1.5hp submersible consumes around 2.2kw steady though that is not a problem for my 5kva inverter but I won't try it in 3.5kva

ojeysky:
Typically a good 3.5kva inverter should be able to accommodate 2x surge, if that is not the case then that inverter isn't good enough. I am also not sure a 1.5hp pump surge should get up to 5kw....I have a feeling yours probably tripped because of battery lvd

ojeysky:
Instead use the 3.5kva with maybe 160ah 24v or 48v lifepo4

dacool1:
Which would you oversize, battery bank or PV array?

Please share your reason.

FEGEITOK:
Please what is the experience like running a charge controller on the very edge of its capabilities?

Let me explain.

According to the poster immediately above, the max rated power of her charge controller is 3000 watts in a 48 volts setup while the max PV open circuit voltage is 150 volts.

Has anyone run their charge controller at the max rated charge power and max PV open circuit voltage?

Is it recommended? or should I allow for some headroom?

If yes by what factor?

Thanks.

finebois:
Hello house.
Please is it advisable to charge inverter battery with NEPA light, or I should just stick to solar source. I will appreciate your honest reply.
Thanks.

Got a 120A Felicity Charge Controller from @justcallmenuel last weekend for a good price. I was a bit crossed with him because he didn't keep up with his promised delivery timelines. He promised he can dispatch same day, but I didn't get the controller until 3-days later and I needed it urgently because one of my CCs just crapped on me without warning.

But, I'm ultimately happy with the purchase. Thank you @justcallmenuel.

Peterlove11:
From the few times have transacted with justcallmenuel. I can say boldly the experience has been good. And I can safely recommend him. Based on your side of the story, I think it's an issue of understanding, since Abeokuta park is no longer available, i think he is handicap. The two of you are egbon, and I believe you can both find away around it.
Talk to him I believe you can find a mutual ground for the delivery price.

GRACEGLORY:
Dolby Atmos is the ultimate in surround sound right now. Sony has managed to squeeze the Atmos effects into a single soundbar.
The Z9F sounds detailed and clean, with plenty of bass from the bundled wireless subwoofer.

Built with 4K pass through, HDR and Dolby Vision signals from your 4K Blu-ray player to your TV, and with two HDMI inputs underneath, you could also hook up a games console

USB port for playing audio files directly from a memory stick, including high-resolution support, and it comes with Bluetooth for direct streaming from a smartphone. Spotify Connect and Chromecast support complete the set.

Google Assistant support is potentially more exciting, letting you control playback with your voice instead of the remote control.

TechGeek777:
Thanks bro, do you mind staying the inverter model/series you connected the CC to?

TechGeek777:
From recent videos I have watched, they said latest/recent Felicity charge controller are built not to take power from your battery at all, this means you can only use the CC when there's pv available.

Also, when there's cloud The CC will be showing fault mode if the pv is not sufficient to power the CC.

At night the CC WON'T display at all, and from the videos the CC wakes up at about 7am.

So your CC is doing perfectly fine.

The motion is to conserve battery.

All modern Felicity CC now have this feature embedded.

Gr8teejay:
Good morning geniuses in the house. Please is it recommend to leave a battery charging through solar and travel for a month or to disconnect and go?

dollarnaira:
What of the air you inhale outside the house.
Certain things are just too "overly exaggerated"
Your opinion though so no qualms

samnaija:
My taught exactly, he should beef up his solar panel generation, and switch off the grid meter. I don't on my grid meter at all, unless the weather is very bad..

My big engineer's in the house as my first question was ignore please I want ask.is 24v system ok for 2500watts continuous load with Stan alone inverter? Or 48v system is ok? another one is
24v highbrid inverter vs 24v stand alone inverter which one is more efficient

NiyiOmoIyunade:
Let us decompose this a bit.

1hp is approx 746watts and 1.5hp is approx 1,119w. Since we are discussing a pump and not an AC, there are really no other ancillaries drawing power apart from the pump motor and we need only worry about the spike from start up draw in the first few seconds.

In a 24v nominal system, the system voltage is not at 24v. Let us assume 27v operating as a good midpoint for when the battery has a charger applied and is in bulk, absorb or float.

When I gross up consumption over operating volts - 1,200w / 27v - I see a max draw of 45a from the 1.5hp pump and if I generously allow for voltage sag to 24v, a max draw of 50a. The average 12v 200Ah lead acid battery is rated to deliver 40a safely for well over 30minutes and for our test case we have at least 2 units to make up a 24v nominal system.

Further, if OP triggered his water pumping based on battery at absorb voltage, there is some PV potential to fully offset the pump's draw or take some of the bite off.

I know you know this math, I have just rehashed it and done it properly so that people are not misled - I also design systems like this on the regular and they do work in practice apart from the fact that they work on paper.

If you wish to explore a practical mechanism to make this happen and not throw the battery to LVD, then we can do that upon your request.

NiyiOmoIyunade:
400Ah 48v of lead acid to support water pumping for a max of 45 minutes every other day or so?

I think it is rather much - most agree that some juice coming in from the PV will offset some of this burden quite nicely if not all depending on timing and irradiation levels.

Truly it is not even compulsory to run a 1.5hp pump off the solar system - a standby generator fired up every 3 days or so may just be perfect for the need.

I started off with lead acid and used and sold all the common variants from AGM to Flooded to Gel, now I sell LFP batteries exclusively (Pylon tech) and assemble my own LFP packs - despite my very positive experience with the LFP chemistry I do not recommend it blindly for all situations - small systems can make do with lead acid and give a very nice return on investment (I gifted 3 small 12v lead acid systems to 2 relatives and a young friend in December 2022 and all are as happy as can be) . Lead acid is a very easy and simple place to begin the RE journey from.

earthrealm:
Errrrm,
I think from some of the responses so far, we are missing the whole point of cedarfarms enquiry.

I wont be drawn into this useless shenanigans , lithium vs leadacid battery, cos whatever anyone is using/decides to use. Leadacid o, lithium o...e no dey put shiishi for my pocket , why should i cry more than the bereaved?

Its best you give your advice, focusing primarily on a design that will work for cedarfarms.and not focus more on attacking what someone else has said.

I gave my answer based on what i feel is best for him/what i would do if i were in his shoes.
From his questions/comments here...you can guage his knowledge/experience level----without any disrespect to him, he is a greenhorn in this whole solar-inverter biz, so i factored all those in, b4 giving my recommendation....and it would be nice others think along that line too. And dont come up with complex solutions that OP might not understand or be able to actualize.

Las las he will be alright at the end,

Namzy:
Were you able to communicate with your felicity 120a charge controller? I bought the cables but can't seem to connect to watch tower or mppt tracker software

jonescosmos:
Hmmmmm, bros you just use idea insult me sha, no wahala. Naija people sabi raise dust where there is no ash, I don't think my question waranted such a response from you and I deserve some sort of appology for that.

Anyways there are many ways to communicate and manage felicity devices, I'm sure you don't want me to educate you on this too. I just needed you to be specific as to what you wanted to communicate with the battery but since you said it's with computer, Felicity uses EDMS Software or DessMonitor Platfom and Logger. You can contact their customer care to request for the EDMS software or simply buy their Wifi or 4G Logger. The Wifi Logger uses RS232 while the 4G Logger uses both RS485 and RS232.

Thank you.

Communicate it with what?
