November 27, 20196 yr Hi I have 4 Axpert mks inverter 5kva, and i connected it as parallel, but i need help for detailed steps of programming it as parallel mode Single phase. And Should the order of inverters be considered? Help me please.

What comes to mind is the current sharing wires between the inverters and the parallel cards and cables between the inverters. All inverters should be connected to the same battery bank. Usually at setting 28 on the inverter you have a option between PAL, SIG, PH1, PH2, PH3. You need to set it up as PAL, this mean it will run in parallel to the other inverters connected. Make sure all of the inverters are set at PAL (parallel) Usually setting 01, 12, 13, 26, 27 and 29 will change on all slaves as soon as you change it on the master inverter. Master inverter should be the inverter that starts up first. Order don't matter. Hope this was what you were looking for.

Hi Wilfred Thanks for your response Can you help me please for detailed steps of programming? What i should be do? Step by step please. Edited November 27, 20196 yr by Moallam
November 27, 20196 yr You should have received a manual with your inverter as well as with your parallel Card/s. I also forgot to tell you that all inverters in parallel should have the same firmware. Also see image attached, if you still struggle, I have a couple of manuals downloaded on my laptop which I will pm you if needed.
November 27, 20196 yr To check firmware, scroll through the LCD display until you find U1, I think that will be the firmware. What batteries are you using? Edited November 27, 20196 yr by Wilfred

I have 0 experience and knowledge with the setup regarding Gel batteries. Many of the active members on the forum will be able to assist with those settings. The pictures I posted earlier should be sufficient to get the parallel setup going.
November 28, 20196 yr Make absolutely sure that all the wiring is in place, and all the inverters have setting 28 set to PAL, before paralleling the outputs. You should have a separate breaker on each AC-out; don't turn on more than one at once until you are sure of this. When I finally get to parallel mine (waiting on wiring), I'll be checking with a multimeter between output actives to make sure that they are at the same potential (up to about 10 VAC difference). Find a paralleling manual specific to your inverter model, e.g. this one for Axpert MKS (not MKS II): https://www.mppsolar.com/manual/PIP-HS,MS (PF1.0)/PIP-HS_MS Parallel Guide (9-units).pdf Do NOT attempt to guess how the cables are to be wired; they never make sense to me. Find the diagram for 4 paralleled machines, and follow it strictly. You'll need the "paralleling" cables (like an EGA or VGA connector at each end), and the "current sharing" cables (lightly twisted pair with 2-pin terminal blocks at each end). If you didn't get these with your paralleling boards, you'll have to talk to your supplier. Of course, each inverter needs a paralleling board. This is all in the paralleling manual, so step one is to find the right manual for your machines. If in doubt, post a picture of the sticker on the side of one of the inverters.

I'm having an issue where the setting 01 doesn't change from master to slave (or vice versa) on the LCD screen, however the operation does seem to show it changing. i.e. both set to SUb -> change master to SbU -> Master shows SbU on setting 01, Slave still shows SUb on setting 01 -> both inverters change to SbU operation for some time, and then seem to revert back to SUb. This is becoming a problem with my Solar Assistant as there really is no control over the output source priority and, consequently, the power management function doesn't work. Has anyone else encountered something similar to this, setting 01 not changing between master and slave inverters?
