Drgreatone:
Get a lipo4 with smart bms. The LVD can be set to 12v so it trips off the battery or play the human observer and ensure u switch of once battery gets to 12v

I like this new term

omotoda:


The LVD of my inverters are 10.5v.

Enjoy!

In fact i stopped observing and drain hell out of the battery. No more pampering. However, I hardly hit 11.5v.

Now available!

Powmr 12.8v 100ah (1.28kwh) LiFePO4 battery.
Price: 296,000
Location: Lagos. Waybill and dispatch can be arranged in less than 24 hours

- Comes with a free external voltage meter to show battery voltage in real time
- Made with Rept Grade A cells
- BMS (Battery Management System) gives a maximum charging current of 50A and a maximum continuous discharge current of 100A. But it can also a discharge of 200A for 3 seconds. BMS offers relevant protection against over-charging, over-discharge, overload, etc.
- Operating voltage range is 10v - 14.6v, but BMS cuts off at 9.1v, lower than the LVD (Low Voltage Disconnect) of most inverters, so inverter will have no issues "waking up" after a shut down
- Can be connected in series or parallel to give 12v, 24v, 36v, 48v

Capacity Test Video:

https://www.youtube.com/watch?v=JTtdMd25__s

Important summary of video test:
- After full charge, battery gave a run-time of 7hrs 30mins on an average load of 150w before reaching its nominal voltage of 12.8V (80% Depth of Discharge [DoD]).

- At inverter LVD (Low Voltage Disconnect) of 11.3v, battery had ran for 9hrs 16mins on same load, giving a capacity of 105ah - even higher than its rated capacity of 100ah

- Then it gave another run-time of 1hr 30mins on a DC average load of 20w, giving 107ah (7% more than its rated capacity) before BMS LVD at 9.1v.

This discharge test was done twice and capacity remained the same

How does the concept 'idle consumption' work
a) Is it the self consumption of inverter when it's power on without any load?

b) Does the idle consumption adds up to load when load is applied e.g inverter with 50w idle consumption, if 50w load is applied does it make it a total 100w load consumption?

Yes.
Don't know if there was a contrary.

Is wilion a good inverter compared to srne?

SRNE is better

SRNE is better

SRNE or Growatt, which is better?

@valto and other gurus please I need your advice on the best step to take

I presently have 2 different setup

Setup 1

5kva 24v felicity inverter , 60ah mttp felicity charge controller, 2 units of 220ah wet cell battery and 4 units of 280watt felicity

This setting power my tv and other appliances

Setup 2.
2.5kva inverter, 40ah mttp charge controller, 4 units of 150watt and 2 200ah dry cell battery.
This powers only bulbs

Setup 1 is working very smoothly without issues but I am having a feeling setup 2 battery is bad ( yesterday I put ON 8 energy saving bulbs of around 20watts each from 9pm and by 5Am the low battery sign began to blink)

If truly the setup 2 battery is weak, can I move the setup 1 battery to setup 2 ? and then get a good recommendation here on the best battery use for setup 1

Both are on the same level

During my research, I discovered a solar-powered freezer that I believe would be ideal for my customer's ice block production business, enabling them to manufacture ice blocks for sale. Attached is the picture.

Has anyone had hands-on experience with this solar freezer? I've learned that it can operate on both AC and solar power, which is convenient. However, my client's specific requirement is a freezer capable of producing ice blocks, and I'd love to hear from someone with practical experience in this area.

A few weeks ago, we purchased a Hisense chest freezer, which unfortunately turned out to be a disappointing investment. Despite running it for three days, it failed to produce a full ice block, falling short of our expectations.

I'm seeking recommendations for a reliable freezer specifically designed for ice block production, beyond homemade solutions. Your advice would be greatly appreciated.

Will be waiting in the comment section.
Thanks all

The ice block makers I have seen in the markets are locally fabricated like the one in the video.

You will hardly find a freezer that produces ice block.

Most of those freezers that does so has been modified starting from the condenser, to dryer to the gas and even compressor (yes the compressor some times are modified if necessary).

Although there is a video of a solar fridge that produces block. You can look more into it experiment and give us the real facts .

Meanwhile I can help you ask questions about it

Thanks chief.. Abeg help ask around.. I they wait.

Don't waste your hard earned money on any sokar freezer if you want to venture into iceblock production.

If you want to start on a small scale, go and get tokunbo standing freezers (Liebherr brand or any german product)

If on a much larger scale, get a reliable technician to fabricate iceblock machines for you. this will require compressor of 2Hp and above.

Peterlove11:


Infrared cooker are good too. They cook fast, efficient and you can use any kind of pot on it. That's what I use on my inverter. You can consider one

How many watts do you normally set, and how efficient is it at that rate?

Obnoxious2001:


Then no dey buy am
Na Glass, but you can dash them the aluminium frame

Yo!
You're wrong brof...I tried to sell it and guess what, I sold each for 10k ... I mean 10k Naira per after I kept increasing and increasing my asking price, something In me told me it's hot cake to em!
I had to sell only two and leave the rest as I felt I was being cheated sef.
I think there's some silverish material underneath the glass if you look closer.

Even the aluminum frame is not worth 10k. Who knows what they use it for. Super interesting to see this and thanks for sharing.

Thanks chief.. Abeg help ask around.. I they wait.

Information reaching me on this is that the solar fridge takes 24hrs to create/ make the ice block.

Is it energy efficient yes .
But then, this is a lot of time to produce ice block

mctfopt:


Even the aluminum frame is not worth 10k. Who knows what they use it for. Super interesting to see this and thanks for sharing.

As in ...but it has done silverish material

Thermocool 519L chest freezer for sale, just in case anyone out here is interested.
I’m selling because I wanted to replace it with a standing freezer, I realized standing freezer is better for ice making as water packs can easily rest on the steps inside compared to chest freezers it’s hard to keep the water packs standing.

Price:500k
NEGOTIABLE!
WHATSAPP: 070 6456 5310

Obnoxious2001:


You will hardly find a freezer that produces ice block.

Unless I'm missing something, everything in my Hisense freezer freezes rock solid in hours.

Abi ice block dey different?

RickyM:
24V 1500W rated power and a surge power of 3000W
Perfectly working fine, no issues!
I’m retiring it because I’m switching to an hybrid inverter.
Any interested buyer should respond to this message, I can waybill so location won’t be an issue

Sold

Ice block will take 3 days+ straight for it to be Solid round
