lopezjm2001 The error only shows up long after the update. I will be going for 73.00b I have not updated my firmware yet so cannot give any feedback.

Will go for 73.00b, Thank you

Thank you, I thought so too thanks to the reply from Coulomb. Will try and downgrade the firmware as soon as I get access to the inverter again.

Thanks for the quick response. Bought it in March 2015 from an online store in South Africa(bonanzatech.co.za). Do not currently have access to it at the moment so cannot give you the version number. But I believe I did install the firmware version 73.00 which I downloaded from one of the forum sites. Updated this about a 2 months ago. I suppose the first step will be to restore the firmware to something more suitable to its age. Will update to this post once I can check the version number. These are the firmware files I currently have. 4048MS 73.00 (Installed at present) PIP-MS_5K72.40 dsp_LC1_72.70c System: Axpert MKS 5KVA Inverter(48V) 3 Banks of Trojan T105 9 x 240W (3 strings of 3)

Hi, Need assistance Have an error code 90 on an Axpert MKS 5KVA inverter. Tried searching but could not find error code 90 anywhere. Need to know what it means and how to fix it. Have shut down and restarted the inverter with all loads and PV off. The same error remains.

Thanks Chris Will connect this weekend.

Am I missing something? Started connecting the HA-02 ( wire pair A to battery 1&2) Connected Battery 1 without any problems. However connecting battery 2 to wire pair A is a problem. Connecting the negative of the HA-02 to battery 2 caused the cable to burn off. The positive blows the fuse immediately.

Thanks Chris Will be connecting them this weekend.

Hope you don’t mind me resurrecting this thread. Some questions to do with connecting the HA-02 battery balancers. We have 3 banks of 8 Trojan T105(6V) Batteries and 3 HA-02 balancers to connect. 1. Do we connect 1x HA-02 to one bank. For example the first pair from the HA-02 will go to battery 1 and then be connected in parallel to battery 2. or 2. Do we connect 1x HA-02 to 2 banks. For example the first pair from the HA-02 will go to battery 1 in bank 1 and then be connected in parallel to battery 1 in bank 2 Do we only fuse the positive wire to each battery?
