Power inverters for home use in South Africa roundup - February 2023

Yes, the Axpert King can blend power, it can't push back to the grid.
 
Is that an Axpert King?
If i had know that i would have said the synerjy is an axpert king

I don't know what it is , i jave heard some say it is an axpert

Tried to marry that to axpert no success

Found references to axpert king that is grid tied

So who knows

All i do know is i have an inverter that looks a lot like an axpert but it is hybrid and can grid feed
 
Nice, does it have a CT coil? Is it NRS certified?

The King looks like this:

Don't know
Don't know
And as far as i get it they can look however manufacturers choose to package them ie this one looks nothing like your image

That is rack mount, the other is wall mount.
Many inverters come in a box with a screen and 4 buttons setup either wall mount or rack mount

Pictures mean next to nothing is what i was trying to point out

Saying this is what axpert kings looks like is problematic

At best you can say this is what company x implementation of axpert king looks like

Pretty sure you will find their axpert could look exactly the same, companies like reusing certain items to save costs

ie the case the screen etc

Take the synerji as an example
I know of at least 3 5000w models that look exactly like mine

ie you get an off grid one (self explanatory no grid tie)
Hybrid (grid tie)
And a model that has a pwm instead of mppt
That's just the 5kw models

Other models use the same case
3kw 4kw
With 24v 48v sub variants on some

I could not get a manual for my specific model ,suppose if i keep going i will

I stopped when i got a 3kw model with the same grid tie, ,mppt and menu setup

Cause that was all i needed guidance on what each menu item represents

Ummm, I included the pic because King inverters have the screen at the bottom.

Does yours blend power?
 
Sorry, I'm pretty new to all this stuff. Does that mean that the inverter could potentially over or under charge the batteries since it can't tell the battery's charge level correctly?
No the BMS should protect the battery.

The issue comes in when you want to discharge 30/50/70% and leave the remaining capacity for load shedding. The top and bottom voltages are well defined but to try target a % of SOC using voltage on a battery is a crap shoot or so I've found.

Yea the only reliable way to get a SOC on lithium iron phosphate is with a shunt, that actually counts the amps ,even these items can drift so from time to time you still need to charge full for it to recalibrate again

Coulomb Counter, but rather just get something that works Victron :p

What if he was asking that question from a lead acid point of view?
