Hi,
can someone tell me why my mppt 150/100’s gui does not correspond with the maximum peak power value which is 880Wp (2x4x110Wp) in my case. The circle in the screenshot looks like that it‘s like less than 50% of the max reachable value. The mppt was used with an 1.100Wp system before. Could that be the reason? If so, do i have to reset the history or loading the factory defaults?
Thanks for your help!

The maths for he PV array output, and the battery input are very similar.
PV array output. 66.09 x 10.5 = 693w.
Battery input. 13.55 x 50.01 = 678w.
You are also producing 691W of your 880W potential so that is great.
The way the graph is showing the wattage as a part of the potential of the mppt not your array. Or at least that is the way I have understood it.
Your mppt has no memory which would affect it's current or future performance. So no point 'resetting' it.
Maybe look to your solar (weather) conditions, panels clean, very hot, etc?
Mayby my question was misleading. The thing i‘m wondering is the graph representation. not the numbers. 691 of 880 is like 78%. But the graph shows something like less than 50%.
880w is like optimal conditions..
Good sun (no cloud,haze/shade) at optimal 90d angle, sun to panel...
25c cell temperature..
Its possible your Victron Connect display is reacting to the settings for the system it was connected to prior. The unit does have settings in memory that affect voltage, charge rate, etc that need to be set to the battery type and capacity you are using with it to work properly.
I wouldn’t reset, as factory default settings might be farther off than you are now. But I would certainly change the settings to match the battery pack you are currently charging. Then see if your display corrects.
One thing’s certain... having the correct settings in your SmartSolar won’t hurt a thing!
