With US3000C you can now connect up to 16 units in one stack without LV Hub.

Should I understand that it is only in the SUB mode that the problem with the feed in to grid problem occurs, meaning that if the inverter is configured in SBU mode, this will not happen? Jesper

Thanks for your explanation. Hopefully this is resolved on the units I will receive. A different between the 7200 and the 8000 model is not just the AC output but also the MPPT charger. It goes from 80A to 120A. I have 30kw pv, so I am going to max out the inverters pv power input capacity. So I was thinking that the 8000 model is good for me to utilize my PV power to the charging of the battery bank. I am also considering to double up the battery capacity in a year of two, when I have made enough savings on our electricity bill. There is something I don;t understand, maybe you can explain. The 7200 model has a max pv power input on 8kw, the same for 8000 model, but the inverter output is bigger and the charging is bigger on the 8000 model. Why is it that the rated pv power input are the same on the two? To my logic it should be bigger on the 8000 model. Jesper

I am about to buy 4 units of the PIP 8048 MAX inverters. Do you think that this issue with feeding back to the grid is resolved in this model? I will use it in SBU mode, only using the grid as a backup when the batteries gets too low. Thanks Jesper

I did't get this about that the Inverter needs 1.560 KVA. (Kilo Volt Amp) Thanks for the SUB and SBU mode explanation. Jesper

What do you mean that the inverter needs big VA (1560 VA)? Please explain the SBU and SUB mode? Thanks Jesper

You say it feeding power into the grid! Is that the 7248 model? That is dangerous for the utility line people!! How can an off grid inverter feed power into the grid? Is it not an automatic transfer switch/relay, which open/close the connection to the AC input? That must be a fundamental design fault! Jesper

Okay, thanks for your input! Jesper

The MPI can do off-grid and feed into the grid and the PIP-Max can be off-grid but not feed into the grid, so yes I don;t need the function from the MPI to feed into the grid, but beside this extra feature from MPI are there other advance with this inverter vs the PIP-Max? You say that the PIP-Max is a newer inverter model and therefor could have more issues. Do somebody know about such issues? But you also say that the MPI has reliability issues compared to the off-grids models. Dos that include the PIP-Max's? Does anybody knows more about these reliability issues? The prices on two MPI10kw is about the same as four PIP 8048MAX. Also both models as direct BMS communication with Pylontech. Anybody else has advice or experiences with these two modes or input which of the two models I should go for? Thanks Jesper

I have 30kw pv. I have 16 units of US3000C Pylontech batteries total of 56kwh. I have a three phase AC installation. The system is OFF-GRID. NO feed into the grid. I am in doubt if I should buy two units of the MPI-10kw or 4 units of the PIP-8048MAX. I am sure that both of the models can do what I want, but I am in doubt if you guys have some recommendation or experiences that you can share. Thank you. Jesper Friis St. Vincent and the Grenadines
