December 8, 20178 yr I have an Axpert MKS 5KVA. This problem started yesterday: 1. I turn on the circuit breaker for the battery and inverter comes on and power cyles while the ON/OFF switch is in OFF position 2. I turn it ON and inverter beeps normally and relay clicks. So no output and no errors. On top right corner of Display, output voltage is 0V. Anyone knows what's wrong?

Always do it on save side find out if it will work or not.
April 18, 20197 yr Has any one sort out the earth neutral bonding by now. I have a 4Kva Axpert inverter I want to connect to my Camper with 4 x 100 AH batteries connected no PV. What I found was that my main EL keep tripping when connected to the grid although the rest of the installation seem to work fine, Concern is that the floating neutral/earth sitting at 110V which is very high and dangerous seen the installation is in my Camper. Any guidance would be appreciated
May 9, 20197 yr [email protected] Please help!!! I have an Axpert 5kva charger/inverter running off solar panels. It works perfectly well, however it will not take power from my 220V generator. It is set up with 220V AC as the input priority When I start the generator it recognizes it but does not charge the batteries or take the load. Has anyone had this problem? Andre
August 23, 20196 yr Nice low cost inverters but, will not function correctly with Polyontech lipo batteries as it CANNOT communicate directly with the batteries. You MUST buy the Centurion Solar controller and it is REALLY unreliable. I returned it three times now and it crashed again yesterday with various problems on the software. Think carefully before buying the axpert if you want to upgrade to LiPo batteries. The system is great with up to 100% utilizing through careful control and setup on the CenturionSolar ("piece of Sht") but not stable at all. Sorry Centution solar, you had a good idea but it was poorly developed, not tested and not at all user friendly. The controller requires regular IT maintenance, and your passwords all over the coding makes it impossible.
February 29, 20206 yr @Coulomb Hi coulomb peter here new to the forum Have done a number of installions with lithium ion batteries on compatible inverters. have heard of a few people connecting lithium battries to axpert inverters without the lithium ion battery option in the battery menu. I would not see how this could be done safely as the charge algorithms are different for lead acid battries and there is no coms to the bms. is it possible to setup in user define mode for the lithium ion or is it a non starter. I understand that the bms would protect the battery but that would pose a threat to the mppt? Thanks in advance Peter
February 2, 20215 yr Hi, i have the factory specifications on the TX6 or part number 41-070185-00g, you can remove it and then have it rewound according to specification. Email me if you need it I'll send it to you. [email protected]
June 29, 20214 yr Hi, I have 3 axpert mks 5kva set in 3 phase mode. 12 250W panels per inverter. My problem is my inverters don't switch over to eskom when battery voltage low. Is there a setting I'm missing

Is it flashing? You might have really bad utility voltage or frequency or frequency stability, and need AC input range (setting 03) set to APL? Though APL is the default. Also, utility would have to be really bad to make a difference. It might also be phase rotation. Perhaps try swapping the inverters that have 3P2 and 3P3. Though I wonder if that's automatic. I assume that each inverter has one phase to itself, and that you have all the AC-in neutrals connected, including to the utility?
