Posted September 5, 20177 yr I am looking for a firmware for Axpert MKS PLUS 3KVA 24V if anyone has that available. I downloaded from link below but after update it shows battery voltage as 50V. http://www.ostrovni-elektrarny.cz/index.php?page=podpora Hoping someone can help me here.
September 5, 20177 yr Which firmware did you download? This looks like the right one. Note proceed with caution and at your own risk. MKS_1_3K_Plus_0242.zip

MKS_1_3K_Plus_0242.zip Yes this is the one I tried but after upgrade now it shows battery voltage as 50V when really battery voltage is 25V. Further as soon as I connect solar, it shows 12 error.
