Hi Folks
So we have Blue Nova batteries in parallel and as you can see we are experiencing some weird and sudden voltage drops under medium load which then causes the system to switch of momentarily.
Please advise if there some setting i have to change or something i have to look at to sort out this problem.
TIA
It looks as if your loads are causing the voltage drops. Difficult to be sure due to the averaging in the graph over this time period. Please post a 1 hour graph from a recent time period with a voltage drop.
What's the battery capacity?
What loads are coming in? If it's AC with electric motors, the start up current may be causing the BMS to cut the output. This would show in the graphs as a voltage drop, depending on averaging and sampling frequency, may even catch a zero reading. Solution to these types of loads is a soft start device.
Hi
Sorry for the late reply this is a residential property so no big motors and we have a Blue Nova battery with a capacity of 22.5kWh. See below is a graph of the last 12hrs
