Hello, The voltage from the panels is displayed correctly in volts, but the current measured with an ammeter inserted into the panels or with a DC ammeter clamp is about 50% lower than that displayed by the inverter. It is cloudy now and I don't really have any measurements because there is no production. I also use Solar Asistant and there is the real charging current given by the BMS which is connected to Solar Asistant. I am also attaching some more conclusive pictures of what the inverter looks like and what I physically measure. I am looking for a double MPPT electrical diagram if anyone has one. Thank you.

Hello, I have the following problem with the inverter presented above: it does not correctly display the current from the photovoltaic panels and implicitly the production is calculated incorrectly. I would need a diagram of the MPPT to see where the current transformers or sensors that do this are. I think it is a sensor problem and I do not know what they are. Thank you

Hello, I use Solar Assistant for monitoring to which I connected the inverter via an RS 232 cable + USB converter. For batteries I have 3 pieces each with BMS or mounted on a bus bar and for communication with Solar Assistant I have 3 RS 485 to USB converters all connected to a USB hub which is connected to Raspberry on a USB port. In the Solar Assistant application in the settings page for the inverter model it changes to Sumry and it works fine.

Hello everyone, after almost a year of searching for the problem above, today I found the solution and it works perfectly, you just have to change the connection mode from the voltronic model to the sumry model and it reconnects and correctly displays the products of the 2 MPPT and their sum . This remark may help others, no cable is changed, nothing works as if it were voltronic, but it is not.

hello, I sent an email to dextromn and they said that the control board needs to be replaced, I gave the address and they were going to send it for free. For 3 weeks I've been waiting for it to come with a shipment to Poland and from there they will send it to me. I solve it, I will post here how I solved it, until then I see that it works well because I have full sun and in the evening when it switches to batteries the fans work a little and stop and turn on later, during the day they run continuously as much as they produce.

Hello, is there really no solution to my problem?

Hello, I'm facing a problem and I'm asking for your help to solve it. 3 months ago I replaced the easun smv 4 5.6 kw inverter with another Dextromn 10.2 kw inverter that only has an rj 45 port where the wifi module is connected with it communicates with the watch power manufacturer's application, and I have solar assistant. How can I connect solar assistant to communicate with the wifi module so I can use both applications. Thank you.

Hello , I can say that it works well, but the only problem is that it doesn't show the sum of the powers from PV 1 and PV2, I can see them on the display but I can't see them in the Solar Assistant monitoring application, except for those from PV 1, and displays data of a 5 kw inverter which I think is a clone. MPPT 1 and MPPT 2 I think are 5.2 kw each and so far I have only seen powers over 6 kw from 11 kw of solar panels on 3 strings 2x 8 x 450 watts on the south and 10x 320 watts on the west. I am looking for an electrical diagram or after the inverter is cloned. Thank you Adrian

Hello, I have an inverter identical to yours which does not register the production from the PV 2 input, in the monitoring application but it appears on the display and I don't know what to do, maybe we can find other solutions or a software update. Adrian
