You only have to change your bulk and float to 28v on your inverter and you are good to go.

Ok. How do I reach you?

Finally bought SRNE ML4860 mppt charge controller. Bought it used 60,000 naira + 10,000 naira (transportation).
Hopefully, it matches my taste else I would sell it.

As per the load being only 20amps, I can't use a charge controller without using that load port Ooo.

I built a couple of things that 70% of my loads don't use your regular inverter.

My Core i7, Core i5, and a couple of other PCs all run directly off 12-volts.
Even my 39-inch LED Tv-Monitor, and the 24-inches LCD monitor, all run directly from 12-volts.
Tv Antenna (the rotating type) runs off a USB port (5-volts). I just comot the transformer wey dey inside, attach USB cable to it and voila, e work.
Routers and Modems all run on 12-volts.

All my Fans are the regular DC fans I bought used from Arena Oshodi + a few I bought from Aboki Condemn which I fix and repurposed to permanently run off 12-volts.

Then I got a couple of high powered Desktop PCs I built; those need more than 12-volts but less than 20-volts due to the nature of work they do.

So you see, a lot of my appliances need direct 12-volts and to keep costs low, while supplying clean power devoid of noise, I use that port + should power run low (less likely but possible), it auto shuts down and wouldn't drain the battery bank enough to cause damage.

For all the charge controllers I got, I use all those ports, (including the USB ports for those that's got it); those that could cause an issue (due to high current draw), I built a circuit for them to ensure the power is clean enough. I try not to use inverters as much as possible. Na only chest freezers and occasionally pumping machine need inverter and those got their own separate installation

Lol. 12v as its own disadvantages. Try 48 or 72 or 96 volts.

I don't use 12-volts Ooo. I've got a couple of separate set ups.
The 12-volts I run are separate from main setUp.

For a 4.2kw inverter, cant it handle a cooker that consumes maximum 1.2Kw? That even drops to 400w intermittently?

I strongly disagree.

Here's this guy with a 12v 1500watt chinko using an induction cooker

Read my Response again and digest it.
Last last na here them go settle the matter, we dey wait for that day.

At the end of the day if all other factors are constant and total energy output over the cell’s lifespan is put into consideration…Cell with 8000 cycles @ 70% State Of Health total energy output during its lifespan is more than cell with 6000 cycles @ 80% State Of Health.

I doubt it.

good morning everyone, i have plans of buying 2pcs of 590w or 600w jinko pannels for a 12v 1.2kw [mttp cc]setup. although i have plans for upgrade, can i run the setup without issues?

bassdow:
is your powMr inverter Hybrid ?

Yes, it's hybrid inverter. Same internal component as Sunfield, SMS and Welion hybrid inverters.

litaninja:
Erm, why not?

Just to be on the safe side, Technically speaking, inverters usually have safety margins for load, hence overload protection kick in about 5 sec @ 105% - 150% load.
So any load close to 100% use is not advisable, hence my 50 percent rule for extended use.

Yes, provided you don't exceed the mppt voc.

UPDATE

So as adviced here, draining the battery TILL BMS SHUT DOWN is the needed trick to unlock the restriction that came with the BMS. Now battery gets full to user set value.

Thanks for the wealth of knowledge shared freely here.

Please you guys should help me

I installed
Sms (sunmate) 4.2kw inverter
Haisic 8kw lithium battery
600w jinko panel × 5 in series
Problem now is that, the inverter charges the battery very fast even when the weather is very dull, and it discharges very fast.

It can charge to 100% is less than an hour an hour and it discharges so fast.

I installed this setup with 400w x 6 elsewhere and experienced the same problem. Initially I thought it was the low voltage panel that was causing it.

But I'm still facing the same problem with this new installation in a different place entirely.
What could be the problem?

Modified:

The load range between 250-300w

You didn't tell us their load.

Even a 100kwh battery will discharge to the end in an hour if you feed it a load of 100kwh.

Sorry it's an oversight

The load is just 250-300w

Then... Always make sure your charging voltage and float voltage are same. If not, some inverters will push all loads to battery even in sunlight until it gets to that default low float voltage in the inverter. By the time evening arrives, you have a lesser reserve to hold at night.
LFP doesn't like high float voltage, that is staying in one high voltage for long all day.
So i advice to charge and float at 3.45v-3.48v.
You must not follow this. Just my personal preference.

An 8kwh battery will hold 300w all night ( 300w x 16 hours = 4.6kwh).

If you are the installer, dedicate a day to be there and see how many amps are charging it till it gets filled up. Then watch how it's discharging and how many amps are leaving.
Its quite easy to diagnose such problem when you are there. Maybe neighbour de tap light 🤣🤣🤣.
You check each cells too (only if battery let's you see) to see if a bad cell is there. If one cell gets to 3.50v it may read as full when other cells are still at 3.2v 🙆🏾‍♂️🙆🏾‍♂️ chineke.

Its quite easy to diagnose sha when you are there.

You can start by ensuring that the panels are actually performing optimally and that the battery is truly receiving those amperage. It would have been easier to diagnose if the battery has a smart BMS

The panels are producing 2200w in bright sunlight and about 800w in dull sunlight.

Is there a way you can check the individual voltage of the cells without voiding your warranty.

if his pack can hit 29v hvd then obviously all cells are balanced.
