HELP - Easy Solar 48/5000 MPPT is bahaving not Normal during PV Production

Good day

I am Having problems with my easy solar 48/5000's Smart Solar MPPT.

The setup is ESS - Keep batteries charged with a ET112 Grid Meter.

As per the graph below(which are of today and yesterday ) the pv production follows the consumption graph as it should a produces power as expected . All of a sudden the MPPT PV Production starts behaving not normally as indicated in red on the graphs below . I was present both days and there was no cloud cover at all.

I have went to great effort in checking all connections of each PV panel as well all fuse connections from the array's and could not pick up anything. It seems that the communication between the CCGX and the MPPT is causing the trouble but it seems to be difficult to trouble shoot the problem .

I have Contacted my distributor for assistance. But it seems they have not got the answers.

I would really appreciate some assistance if I can get some direction in what could cause this .

The client starts jumping up and down , as they are loosing production and their investment seems to be at risk

Regards

Johannes Cronje

Hi @Johannes Cronje

do you also have a graph of the DC voltage / VE.bus state?

Could it be that the battery reaches float voltage, therefor reducing needed power?
