Hello everyone. I would like to install my inverter differently because the whole house is currently connected to the output of the inverter. I would like to install it parallel to the grid with an energy meter. The system should still function in the event of a power failure. I made a drawing of the current state and the desired state. I'm just not sure whether the automatic transfer switch has to be before the energy meter or after?

Hello, by chance I found a group on Telegram where there are members of Solar Assistant. This is used to exchange information and help quickly and easily. Anyone interested is welcome to join. https://t.me/solarassistant

Yes I’m very happy, because it took a lot of time that he finally works fine. the software is 15K_Reflash_20221126_PW

Thanks riogrande. I updated my inverter with new firmware from FSP. Since update the inverter is working fine 😍

Good morning and happy Easter from Germany:).. thanks a lot for your help, but doesn’t work correctly. Now the problem is, that the display in the dashboard for "solar“ goes over 10,000 watts if i switch on consumers accordingly in the house. such as kettle. for this moment, the display goes up to zb. 12000watts. you can see everything super in the graphic. But if there is no consumers the „Solar“ and „grid“ doesn’t go up over 10000watts but Solar ist producing more than 10000watts. You can see at picture from electricity meter. The electricity meter shows how much feed into grid (12376W)

Hello again, the Dashboard is back and shows some datas. But why does the display only go up to 10000 watts and no more? My Solar is currently producing 11500W but a maximum of about 10000W is displayed.

Ok, will try to join the Beta. I hope it's going to be as good as before

Hello everyone, I installed the latest update. Now I have the problem that inverter and batteries are connected but no more data is shown in the dashboard. Although all the data is read when I click on the inverter or batteries. I also reinstalled the software. But brings no remedy

If I set the charging current to 300A, it still only charges with 100A if feeding into the grid is allowed

I also tried it without Raspberry. It just charges with a maximum of 100A when I have the feed into the grid active. As soon as I deactivate the feed into the grid, it also charges with the 200A

Hello again, isn't anyone here having this problem? It loads with 200A if I forbid permission to feed into the grid. As soon as I activate the feed again, it only charges with 100A

Good morning everyone..... after I had numerous problems with my inverter, the manufacturer sent me the latest firmware from November 2022, which I should install. Does anyone have experience with this and can tell me what I should look out for? I ask because someone from a German forum destroyed his slave by updating the firmware. So now I have to consider installing the update.

The batteries are only connected to the inverter via plus and minus. Communication runs via connection from the battery to the Raspberry and then to the inverter.

The problem is that it has never charged more than 100A. From another forum someone told me that it is a software problem of SolarPower. I would have to enter the double amps to reach the desired amps.

Hello to the round, I have connected to my inverter 8x US2000c Pylontech. In the Solarpower software, the charging current is set to 200A. But the inverter charges with a maximum of 100A. The rest is fed into the grid. What could be the reason for the error?

Good morning everyone.....I'm just at a loss.....I've thought about everything that Steve wrote. As a result, I learned a lot again. My inverter no longer has a parallel mode. Furthermore, I dealt with the C values of the batteries and set the output power of the batteries to 150A accordingly to test this. The problem is still there. Last night between 7-9 p.m. the dishwasher and other things ran. He drew a maximum of 7.5kw from the battery without any problems. This morning my wife drew hot water for a short time. There was a current peak of 10.5 kw, whereby he drew 7.4 kw from the battery. The battery dropped from 49.1v to 47.8v so that the batteries were no longer discharged afterwards. I don't understand anymore. Why does it work without problems in the evening and not in the morning when the battery still had 58% at 49.1v. Do I have to throttle the output power even more, or can I reduce the shutdown of the batteries in the inverter to 47.5v without damaging them?

Thanks for your help, I have found the setting for switch of parallel mode.

Good morning, here is a current overview where you can see that at 3 a.m. after my father-in-law got up, he simply ended the discharge

During the day this is not a problem. Only when PV is off, and Batterie is about 50-75% at night.

That's why my thought was to lower the output power of the battery. But the thing is, now that solar is still available, if I call on 20Kw of power, the batteries don't switch off. Then it takes 10KW from the batteries and the rest from the grid and SOlar. I can test it today by lowering the output power of the batteries from 200 to 150A. During the night my father-in-law will get up again and use the instantaneous water heater. Then I'll see if he stops the discharge again. I just don't understand why he only does it when solar is off. Why doesn't it turn off the batteries at peak power of 20Kw when solar is available.

Yes, we have a contract so we get money for every Kwh. Therefore, whatever electricity is left over from PV can be fed into the grid

Here you can see, the systems runs very well. The picture is from now and last night where you can see the Problem at 3 o clock.

Hi Steve, I am absolutely grateful to you for your help! Because this device gets on my nerves. I can't explain why the solar installer carries out such an installation. He recommended the device to us and also knew what we had in mind. The device should work in such a way that we can supply the whole house with solar and battery power in an emergency if there is a power failure. Therefore, the house is also directly at the output of the inverter. I've read the manual and seen the one with the relay now. I also looked again in the settings, Grid Tie with backup II is set. I thank you for your help!!! Best regards from Germany

Moin 🙂 Moin🙂 Exactly, I think so too and am trying to figure out that I can set the inverter so that it simply draws power from the grid during such short-term peak voltages and does not take everything from the batteries. Thanks, Do you mean like in the picture?
