the problem is : the inverter display on hes screen that there is 2 amps(dc) form battery ,but in fact there is no cureent form battey ,all load's get power from solar panels and when the inverter charge the battery in 20 amps in real ,but the display shows that is the charge cureent is 18 (rong info)

Hi , my inverter is gave me a Rong reads Like current discharging read I need to calibrate the battery discharge current What is the commend i need?

In addition to the presence of a cable to communicate with the BMS battery, and therefore it is supposed to give information from the battery, and given the battery screen, there is no current consumption from the battery

You say that the principle of the Mppt solar charger algorithm is that it withdraws from the battery to raise its voltage again?? Can you mention or specify any algorithm from Mppt that does this

first ,thank you to your help did you do some like this update (41.17) what is your opinian about it??

My friend, first, lithium batteries do not draw any current at the stage of fullness, unlike liquid batteries, which depend on the basis of their work on the chemical reaction, and to keep the battery active, it draws a very weak current after the charging stage. Secondly, the problem that occurs to me is the exact opposite of that. It is not the battery that consumes energy. But the batteries provide power for the loads, although there is enough power from the panels

It means a misreading, is that what you mean? The battery is lithium, and there is no current for the float, so de jure there are errors in the readings, and I am looking for an update to solve this problem

You didn't understand what I meant. If the panels are enough, why does it appear to me that there are clouds of batteries to carry? Watch the pictures carefully, my friend

i know , if the battery is full charge , and load wattage is less then then the PV power , why it is show me there is current from battery to load

yes, the is a BMS , it is a lithium battery, the problem is : input PV 855W , output Power 737 , and there is current from battery , is there an update to solve the wrong readings ???

Hello, I am a new member, I have a 3kv inverter vm iii, and I am facing the problem of the wrong reading on the inverter screen, in addition to the consumption of current from the batteries, although the energy of the panels is sufficient, version u1: 47 00, u2:19 15 any ideas? a
