I own the JK BMS with 2A balance current. Pretty nice and versatile.

A neighbour bought the 300A Daly BMS, will arrive this week.

dollarnaira:


Your inverter is IS NOT CHARGING get a multimeter to confirm.

soladavies:
I checked the voltage of the battery and it's 11.89v. I charge it again for 1hr and after checking, it's 11.84v

saint2ace:

Batteries, 2.5kva prag inverter and Standalone Inverter sold...

Penuelseun:
A 4s system voltage of 16.8v will be too much for my inverter, can still manage a voltage range of 12.4v to 10.0v for the 3s system

What to get into Lifepo4 cells with budget I have this 8 cells used as back up for 4 weeks, 105ah

You can customize to 12.8V, 105AH. 1.3KWH

25k per cell (DIY Busbars and screws included) - slightly negotiable

Having read all the different types of installations & different equipments that our current seniors & elders in the threat have amassed, I have created a wishlist of my own. A dream team that is worthy of being displayed & envied by all. Lol Please feel free to critique. This list is my mere fancy if money wasnt an issue and something to keep me inspired on the solar journey.

Dream Solar Installation:

Solar Panels:
1.Jinko Solar Panels 405w x 12 = 4,860w
2. Canadian Solar 390w x 12 = 4,680
Total Solar Array in 2 strings (24panels) = -+9,720w

Solar Charge Controller:
1.SmartSolar-charge-controller-MPPT-250-100 x2
2. Morningstar - Tristar Metered 60A MPPT Solar Charge Controller, RTS Included x2

Inverter:
1. Victron Energy Phoenix Inverter 48/5000 VE.Bus 48V Sine 4000W 10000W x1

Battery Monitor:
1. Bogart Engineering Battery Monitoring - Trimetric TM-2030 x1 $250

Battery:
1. Fullriver 6V - DC400-6 (8pieces)
2. Crown Battery 6V - 330Ah (8pieces)
3. Battle Born 12V - 100 Ah LiFePO4 (4pieces)
4. BYD B-Box Pro 7.5kWh 48V Lithium Iron Phosphate Battery Pack

This list is not exhaustive and I might have missed something in it. In certain sections I have put two products that can be make the cut depending on which brand is the better product. But a man can dream sha.

Oshomo12:


If you must do Lead-acid battery of higher capacity(500 ah and above, even from 400ah), just use 2v.

samir101ng:

Current Realities:
Solar Panels:
1. Yingli Solar Panels 380w x 12 = 4,560w N65,000 per panel

Solar Charge Controller:
1. Fangpusun Flexmax MPPT80A $290

Inverter:
1. Fangpusun XTM Inverter 4800W-48V $792

A few R3 Basic DIY 6.5k for unit price and 6k for multiple(>3). Can flash with tasmota before shipping for those interested

I am trying to come up with an automation design, perhaps you can advice or suggest.

The workflow will be something like this.

From 10am, whether or not there is Utility, switch loads to inverter, as long as the battery is full. (I am hoping the battery state can be gotten from the charge controller because it has a comms port, CC type is Epever)
otherwise stay on utility and check again every hour
At 4:30 pm, change over to Utility.

Anyone with a way to achieve this? I think these R3 are located to specific loads, right?

Valto:
ok. the 300A daly bms, comes with inbuilt fan.

mctfopt:


Yes, e don land sef

Stuff is huuuuuge...see 6" phone for reference.

i doubt if u will get it at that price now or when u are eventually ready.



why not save your self the stress and flow with new reality. get a 5kw deye hybrid inverter. it is cost effective and better than those combinations (especially that less efficient SRNE). and yes u can order a deye 5kw hybrid for around 410 to 450k

Battery Monitor:
1.Fangpusun BSP-500 Battery Condition Monitor with 500A Shunt $80



lead acid is fading out , lithium is the present/future, with atleast 3000 cycles. since u are planning towards the yr end, why not order 16pcs of 230ah lithium cells @ around 430 to 500k (exchange rate dependent) now, and it would have arrived by year end.

dollarnaira:


Read mine
103 Ohms

So 100 would work

olopan:
Thanks for your input earlier, the watt meter worked and came back to live but I am afriad it has had it.

Voltage reading was 529Vac Amp 31.23
Of 3.20

Flicking the board over noticed it was toast completely ... Something is broken, and since PCB is charred I will get another.

Attached is a picture of the charred Pcb

In order to be sure of my budget, I wish to ask:
If I charge my batteries ( bank of 48v 920Ah) using solar panels ( 24v 2560w ), 3.5kva inverter with 60A CC and at the same time using my appliances of about 600w,
is it possible to get production of 54v display on cc with the peak of sun?

If yes, how many hours precisely?

If no due to appliances usage while charging, what could be done to store current in the batteries for night usage while I'm still making used of the day output from the panels?

Night consumption is 400w.

samir101ng:


Thank you sir for the detailed response. Always glad to learn something new everyday. You know there is this ongoing debate between having an independent solar charge controller (which I am more in favour of) vs having an inverter with a built in charge controller like the Deye. I think the system is better off with a specialised charge controller than risk the issue of failure with a built charger in an inverter. That said, I am on the lookout for a good, quality Chinese inverter that will last me atleast 5 years before I port over to the victrons & outbacks. SRNe, Growatt, Fangpusun etc are amongst the brands I am currently looking at. 5000w 48v preferably. I want to do lead acid for now to enable the lithium technology to mature more before taking the plunge. But we will be getting to that leg of the journey soon too.

1000 usd for just 5ml something is money o. If guys can be donating it for free inside latex bags which will be flushed down hotel lavatories and still pay the escort money from pocket, then it's better to kukuma make money from the activity itself; that is for the action guys dem.
