Hello i am having that exact issue did you ever solve yours at the time it was causing that thanks.

Yes exactly so iwould have to 48v which i need to parallel.

Ok i am changing configuration will be using four 24v lifepo4 200ah instead what balance should i get for those thanks.

do i need a bus bar also to connect everything

Thanks will go with thi sconnection when i am done with project will let you know how it turn out

May be the correct question is i have one of those 48v wall battery @ 100ah and i am getting 8 12v 100ah i want yo add to my sytem with a 48v hybrid invert rated at 7500w thanks just wondering how to connect all batteries with inverter.

Remember i am looking to just switch between two different types of lithium battery one is complete wall battery 48v 100ah and other batteries i want to add to my system is 8 12v 100ah where i would put for each inseries and parallel them which owuld make that side 48v 200ah , then i would like to know if i can connect the dc dsiconnect switch to move form set of battery to other thanks.

Good day i would be happy if anyone can point me in the right direction. I am thinking of getting additional lifePo4 batteries but different brand also different BMS can i use a DC Disconnect switch to move from one set of batteries to the other and how do i connect it if possible thank you in advance forgot to mention i have an Axpert 7.5 inverter .

thank you very much

So what you saying have two strings of 5 panels in series and then connect the two strings in parallel ?

Hello Friends i have An axpert max 7200w with 8 string panles in series at 410w i want to add 10 more panels on the other panel input Can i add those 10 panels in parallel .Here is the pic of panel configuaration. Any help will greatly appreciated thank you.

Actually not at at all i have charging solar only and settings for battery automatically selected by by battery since battery is sync with battery ,Pylonthec. Also this dont happen all the time but some days it works pretty other couple of days just keep happening .

This issue i have been experencing where i have 100ah battery pack connected to my Axpertmax 7.2kw ,when there is no more sun and my sytem switch to battery mode it keeps flipping from battery to grid and while switch my 110v system goes out i have a step down transformer wired for my whole house and also starts humming when it goes to grid. Have anyone experinece this and what did you do to solve issue thanks for responding in advance.

Hello everyone i got parts from digikey and replace them and after i tried the battery to wake up inverter but still could"nt recognize battery ,guess i had to precharge first and voila everything started normal working right now as i am typing here thanks for the input just occaisionally this shit happe where my 110 v get knock and inverter switch to line mode even if battery still have like 58% soc and would tend to kind of knock off my 110v sytem in my house i am thinking is the step down transformer don't really know but thats my only issue kind of have had that problem where it knock down my 110v side but it comes on failrly quickly like milli seconds don't really know whats the cause of this one.Might have to sell this inverter and get inverter with dual output i guess.Working like a charm whenever inverter try switching leading to the 110v supply issue the invert switches to line mode sometimes battery disappear i have had that issue from the time i got this inverter so that wasnt a surprise but apart from that everything working back to normal a little better.

Thats whats up with my board hopefully reeplacing damage mosfet should be good will keeep you update thanks.

thinkis reapir manual not too sure but will try to understand and use it .

think i might troubleshoot using this board and see what happens only certain things on the board i dont understand .

Here i smy board it is equivalent to axpert Max 7200 but mine is PowMr 7200 same firmware.

Where can i buy a replacement board please thanks.

i have a dead short so where do i move from there thank you.

This near battery terminal on inverter side check pic.

How to check short on inverter please thanks.

40 ohms

Can i use one of those

Please can you help me out with my axpert Max .Inverter no longer recognize battery after it got shut down due to running my water heater at the time which 2.5 kw battery was 48% 48v battery .i did a complete disconnect of negative and positive wire from inverter then turn battery on it comes on normal with BMS ,whenever i try to connect the wires from the invert battery terminal the battery getting a short circuit fault .I had a friend to bring his inverter to try connecting battery with inverter but no fault comes up on battery therefore i am thinking problem is with inverter side ,can you direct me where exactly should i start looking in innverter.I have to mention only fault invetrer showing is 6P for no battery .Do you think it is a relay got stuck or somehting like that .i attaching pic of where inverter connects with battery may there might have an issue thanks for looking. The battery BMS fault is SCp which is Short circuit mode.
