thanks looks like i need to dissemble my stack.... 2 of the 3 are giving the same problem

Ibiza did you manage to fix the faulty unit? or what was the outcome of fault? I have exactly the same problem....

Hi Chris Thanks for the reply. I am busy downloading the new firmware will update over the weakened and let you know how it goes. I will play around with two inverters to try and find the faulty inner board.

Hi I am new to the blog and new to solar..... I am busy building a off grid system. My system currently consists of 3 x 5kva(4kw) Axpert Units in Parallel single phase mode my firmware is U1 72 70 I have 20x 330W Solar panels in total. split up in 8 for first unit, 8 for second unit and 4 for third unit. Then I have 16 x Trojan T105-RE battery's total of 450Ah. i have connected all 3 inverters on the same battery bank. I have run one inverter for two months on my lights and swimming pool pump no problem. my problem started when i connected the three inverters up in parallel mode to supply the complete house.... the system run for about 2 hrs and then trip on Error Code 80(Can Data Error). Supplier suggested a faulty comms cable, swapped out cables but still all run smooth for 2 to 3 hrs then tripped again. 1) Anybody had similar problems? Or how good is these inverters running in parallel mode?? 2) What is the optimum setting for the Trojan on this inverters? I have read somewhere on the forum that this is not the ultimate battery for the system(Unfortunately i only read it after i bought the batteries) 3)Is there a newer stable firmware out that that is better for the batteries? Any help and suggestions will be helpful.
