I may not really understand what you mean by "an average hybrids require large panel arrays to power loads and charge at the same time" but I've installed 1.5kw 12v hybrid inverter 150v 80a with 2 pcs of 580w Longi pv and 280ah 12v Lfp battery for someone. He powered his 140w freezer during the day and still get the battery to float before 1pm depending on how deep the battery was discharged at night.
I'm expecting 1kw 12v and 1.5kw 12v high frequency hybrid inverter next month and I'll still test the charging system as well.
The issue you experienced may have caused by the configuration of that charging system by the company.

Can those two 580w longi panels comfortably charge a 24v 105ah battery? And what brand of inverter did you install?

Iinnov8:
1600w (800w) Pure Sine Wave Easun Inverter (12v/24v) with free pair of cable lugs. The cable lugs will come in handy if you do not want to use the alligator clips or you want to "wear" the inverter cables over your battery terminals and lock them in with terminal covers

Below video shows a load capacity test done on the inverter using a 100L non-inverter Haier Thermocool deep freezer (rated 80w), 55" Hisense smart TV (rated 130w), 10kg Maxi washing machine (rated 450w) and 2 units of Qasa AC/DC standing fans (rated 30w each), and it powered all at once without tripping on overload. Second video shows inverter powering an old model Panasonic toasting machine (rated 640 - 760w) and the 55" TV.

Key Features:
- Peak power 16000w; Continuous 800w
- Offgrid. This means it has no charging function. You need an external charger to charge your batteries. You will be fine if you are connected to solar
- Consumes very low power (<5w) from your batteries to invert, so you will get more backup time from your batteries
- Protection against overload. It only trips off with an alarm sound and light when overloaded, but returns to normal working when you switch off and on again.
- Protection against surges from sparks, partial contacts and reverse polarity connections

Price: 69,000
Warranty: 6 months.

Do you have 2500-3000w available?

Hi everyone. Please have any used the POWMR hybrid inverter before? What's your recommendations on it?

Dam5reey1:
This is a very good Budget inverter don't expect much, it will provide 220V to your load.

Its a generic branded Chinese inverter.

Thank you boss. What do you mean by me not expecting much sir?

Good days bosses. Please I need your advise. Does anyone have experience with the AJC hybrid inverter? I humbly request your recommendations.

boss na weee everybody kno reach e go talk.. u re entitled 2 ur own opinion.. so i nor go come argue with u.. me i b hardware guy dat part u nor go fit com close.. i not even de use windows regularly. My main os na linux 4 d past 5yrs..

Boss, there's a clear different between a Mac and windows PC of the range of hardware. Mac is nowhere near perfect but it's a bit optimal and durable than it's windows counterpart.
Note, that's my experience.

Hi bosses.

Please, does JBD BMS do active balancing?

mctfopt:
If you don't, have basic knowledge of DIY, you may need someone that does, for this.

Lemme still explain how this should work. To top balance batteries means to charge batteries in such a way that all the batteries are equally charged to the same voltage.

To make this happen, you'll have to connect all the cells in parallel and charge till the charging current goes to zero.

To connect this DC -DC converter, your charger is the input, and the output (after adjusting voltage to 3.4v) goes to the cells you want to balance.

Find attached the LiFePo4 cells being connected in parallel pending top balancing.

Please do not attempt any of this stuff by yourself if you don't have the basic knowledge of batteries connection and electricity.

Thanks a lot for this. That's why we have people like you on this platform to guide people like us.

I quite understand the basics of electricity and I'm moderately comfortable with small DIY projects. I've just never been in a position to top balance a cell before hence my question to experienced bosses like you.

To be sure I understand well(I'm a slow learner), the converter will convert my 12/24v charger(input) to any adjustable voltage(output) of my choice?

Also, does this converter work like a DC transformer?

mctfopt:
Charge in series with your regular charger until battery is full. Remove charger and parallel your LiFePo4 batteries.

Get a cheap DC-DC adjustable converter and you are good to go. Use your regular 12v or 24v external charger as input. Add a small fan if the converter runs hot.

Do you mean when the highest charged battery Is full? And how does the converter work? Does it transfer charges from the highest to the lowest?

Also for the converter connection, is the inverter/external charger going to be connected directly to the converter or to the battery?

Can the balancer work as well as the traditional way? Also, do I use the batteries while the balancer is working or I let it do it's thing first before usage?

brightk:
unless you buy an active balancer or trus ur bms to do the balancing u nor really get choice

Good evening bosses. Please is there an alternative to top balance new lifepo4 cells? Or how can I top balance without buying a bench dc charger as I cannot afford that for now.

If there is an alternative, I'll be very happy to hear it.

IllRatherNotSay:
Used Schneider Conext Inverter/Charger SW4024 230V (4000W) available. What is your offer?

Is this still available?

Dear Team.

Please, I have a 24v 100ah lifepo4 battery pack. Please, what kind of charger(AC) is it recommended that I use.

Note that we have regular power supply in my area and I am not planning on getting panels.

Considering my points above, what kind and size of inverter is recommended as well?

Do I get a separate charger and inverter or do I get an inverter that can charge?

Total load - 150w fridge and 80w fan primarily.. Abeg no air me bosses.

I don't have bms. They're not top balanced.

Are these still available? I need me some. Please share a contact number.
