What does this mean on an Axpert inverter?
It's been this way all day today

The solar charging line isn't showing

what is the PV input Voltage, snap the side of the inverter where the specifications are.
show the PV voltage page on the inverter as well.
what is your panel configuration, total voc.
It may mean the starting voltage has not reached yet.
this is what I experienced at some point. the starting voltage is 150V. I watched the PV input voltage reach 149, but it didn't start.

Namzy:
A battery can be 70% charged and charge controller will enter float especially those charge controllers that don't have automatic absorption time. So you can deplete your battery and the next day your default 2 hours absorption time won't even take the battery pass 70% before the charge controller enters float because the 2 hours of absorption has reached you should get a battery monitor with lead acid battery. Another crude method is when the charge controller is in float, switch off the inverter and check how many watts the charge controller uses to maintain the float voltage if it's above say 200w or more then you have a long way to go

this is what most don't take note of, you cant really know the SOC on the lead Acid unless there is a capacity meter that most don't use.
people will assume they only pump during the day without noting that battery maybe on float and it will take some time for controller to go back to bulk harming the batteries without knowing.

Because of poor charging algorithm, efficiency tubular and lead acid is just a no no for me. especially in 2024 where price of LFP has fallen.

Drgreatone:
Anyone used this controller before? The mppt has solid history so hoping this wont disappoint. Like the LiPO4 ability.

This will work as a PWM charging, nothing much to expect.
it has an LFP profile so you can configure it to charge based on 2 two-stage LFP CC/CV charging methods.

Good day bosses in the house...

Abeg make una help me with solutions to the below problem ..

Did 4.2kw 24v installation with two 220ah tubular batteries abt 2mths ago.

Now the customer sent me a message this morning that for abt one week now the batteries goes off around 2-3am with just DC bulb load (10pices of 5W each).

Load use on the battery.. 1HP pumping machine.. Once in abt 3 and days,running hrs like 1hr max during the day.

Inverter fridge and freezer from 8am to 6pm now reduced to 3pm

And the DC bulb for night useage..

Kindly note that the batteries get alot of charge before the sun goes of.. It always in the float state before it comes down to the normal 50% battery level and still sound for low battery warning even without much load around 3am max..

What can i do to rewake or b boost the batteries pls..?


Thanks all.

you are running about a 1KW load on 2 Tubular batteries. this is a stale story.
these batteries are for light loads.

Hello bosses in the house.
Please help to recommend solar inverter setup for one deep fridge, 42” television, 4 ceiling fans and 15 bulb.
Budget is about 2m but flexible

2.5M will do the following at the moment
48V 6.2KW Inverter 400K, 48V 5KWH LFP 1.2M, 2200W Jinko panel 640K will get you accessories and installations.

2M
24V 4.2KW Inveter 350K, 800K 24V 3.3KWH LFP, 2200w Jinko Panel 640k rest for accessories and installation.

These Budget Brands include: Taico, Sako, Welion, SMS, DIY packs.

At least use protection.

Good Job! Voltage shows an excellent sign.

Good afternoon. Pls on Sako hybrid inverter 3.5kw 24v is the battery LVD settable? Thanks

Of course yes, its same interface as Axpert variant

Ooreofegrace:
Una kindly attend to my query abeg

Ooreofegrace:
Una good afternoon here bosses.. Abeg make una help me with the wattage of this Samsung fridge/freezer pls..Also, how long will a 12v 100ah lifepo4 or 12v 200ah lifepo4 battery last with it after sun pls let say after 6pm.. Wanna see if we can move the fridge to lifepo4.. Journey to lifepo4 done one begin be that..

Most of the time Energy ratings on Appliances are peak power and not continuous power, especially for Heating and cooling elements.

The best way to understand your usage is to add an energy meter, Smart plugs, and a watt meter plugged it will calculate your usage.

For the sake of a rough estimate, take the 270w as the power.
270W Plus 30W inverter consumption is 300W rough estimate.

your 12V 100Ah is 1280wh = 4 hours usage
12 200Ah is 2560 = 8 hours usage

brightk:
omo the cost nor b hear oo. This piple de follow deye for yansh

What most failed to understand is that product pricing goes beyond quality alone.

Service and customer experience plus a long warranty are what determine the value!

If you want hardware and are ready to live with any quirks afterward.

All these people sell similar hardware

Nice. Please share link if available.

Una weldon for this dept.. Anyone with 1st hand info abt this battery.. Anyone done use am before. How good is it..? And hope no be fake (upgraded tubular battery)..? Thanks.. Will be in da comment section reading..

Buy and Do review for us, I asked the Seller some questions, but I didn't get any favorable response, I would recommend you go with a Known tested brand if possible DIY.

Trippledots:
Hi, where did you get the PowMr inverter from?

isangjohnson:
When you say "story", are you arguing with the cycle life of various cells EVE manufactured or you're arguing with the price range I posted for the 12v 100ah and 24v 50ah cells?
Let me understand you Sir

I wrote Story because you typed about cell capacity that is out of context.
I asked a direct question, Just put the answer.

which cell are you packing for 12.8V 100AH that is selling for 250K?
and which one is in the 25.6V 50AH that is selling for 385k?

I was expecting a simple answer which is 50AH cell is sold at a price close to 100AH. and not that it sold at half of the price of 100AH.

isangjohnson:
Cycle life varies and that is what affects the price.
If you go through EVE batched and matched grade A cells list, you will see various cells with different cycle life and charge/discharge rates.
50Ah has 1500 cycle life with 0.5C/0.5C charge/discharge rate.
Another 50Ah has 7000 cycle life with 1C/1C charge/discharge rate.
101Ah has 2000 cycle life with 0.5C/0.5C charge/discharge rate.
102Ah has 5000 cycle life with 0.5C/0.5C charge/discharge rate.
280Ah has 8000 cycle life with 0.5C/0.5C charge/discharge rate.
304Ah has 4000 cycle life with 0.5C/0.5C charge/discharge rate.
306Ah has 10000 cycle life with 0.5C/0.5C charge/discharge rate.
628Ah has 8000 cycle life with 0.5C/0.5C charge/discharge rate.
When I checked the price a few days ago, 280Ah and 304Ah were sold at the same price because of cycle life.
In secondary market, cell vendors buy the rejected cells at different prices too and cycle life is part of the reason.....

Story, which cell are you packing for 12.8V 100AH that is selling for 250K?
and which one is in the 25.6V 50AH that is selling for 385k?

Please and please:
Avoid solar generators at all cost. I mean a solar component that has both inverter and controller affixed in one board is total rubbish.

Why I’m saying this…

My qasa solar generator just explode on its own. It let off smoke 💨 and then boom 💥
Thank God the incident happened while I was at home, otherwise “Na only God know”

Now I’m looking to purchase an inverter+ controller (1500w -2400) if anyone has these items, used or new please quote me

There are so many factors that may affect your setup, you may highlight how your own was set up, so others can learn and not make similar mistakes.
Also note that the Solar Generators that work are expensive, Bluetti, Sunking, etc.

isangjohnson:
Though the purchase price wasn't mentioned, but buying 24v 220ah used lead acid with usable capacity less than 2.6kwh isn't economical at all.
Getting a fully coupled 24v 50ah with the usable capacity of 1.15kwh at the range of 375k-385k is far better.

isangjohnson:
If your inverter charging parameters are compatible with lithium battery, then buy fully coupled 12v 100Ah lithium battery at the range of 230k-250k and have rest of mind.

Something is not adding up.
why is 12V 100ah 250K and 24V 50ah is 385k?

HeavenlyBang:
My panels are acting up.

Twice now I've noticed them completely refusing to generate more than about 300w.

Sun is out, no evident shading, my friend using solar nearby is getting enough power from his array.

Jinko 3x 580w panels, ordered from Foauni. Right now they're only making about 280w. Battery isn't even charging, since the load I have on is taking in all of that.

Tried putting on a heavy appliance to see if it'll get the panels to send more power but nope, nothing.

There is Li mode on the Inverter, this has to do with Settings.

What type of batteries is it, and what are the charging Voltages? Lithium Bulk and Float must be the same.
Provide more information about the charge settings, Current and charging mode, etc.
