Thank you for the info. So best way forward would be to sell them separately and get a new 10KVA unit with BMS system. What brands should I be looking at any preference there,

The one thats the master gives output only. The slave one only charges the batteries and every minute or so where is says SL ot goes to Ne for a second and back to SL again

This is the mecer unit

This is the Rct unit

Hi everyone I have the mecer and RCT inverters 5KW each, connected in Parallel a few weeks ago I had to have the Mecer inverter repaired as just failed stopped working,since i got it back i just had problems,the firmware changed which meant they couldn't communicate took it to another place to up date the firmware now they do communicate but only the MS inverter give output.I have gone through all the wiring all is good.If i reset them and change the master to the other unit then it provides an output so it tells me mechanically all is good can still be software problems Please do you have any advice for me Thanks in advance

Hi Mustek in Richmond centre still repairs those mecer units
