Does Battery Monitor show percentage of total, or the set limit?

Hi Guys, Ive just installed the 712 Bluetooth monitor, Ive set the correct battery set up and also watched the set up video for the sync settings, I'm using AGM batteries and have therefore set a discharge limit of 50% - The question I have is that say the monitor shows 75% battery %, is that 75% of the total capacity (In My case 400AH) or 75% of the set discharge limit (IE 75% of the 50% limit (or 200AH in my case) - Thanks....

The % is of the total, so your alarm will go at 50%, 200Ah

I have a SmartShunt so I assume the settings are similar with your BMV.


The State of Charge (SOC) % is the remaing percentage from the total battery capacity you set (400 Ah in your case), as Harold alredy said.


The "Time remaining" estimate is the estimate time left (at current load) to the "discharge floor" you set.


Be careful: this discharge floor set here (in the SmartShunt/BMV settings) is only used to estimate this "time to go / time remaining". It is not a discharge limit for the inverter. You have to limit the inverter to not discharge the battery below a certain voltage (or SOC) using settings elsewhere (in the Inverter and in the GX device if you have one and if using ESS for instance).
