Hi.
I want to use a Multiplus and some pylontech US3000C batteries without any PV attached (kinda like a UPS for the whole house with the batteries charged from the grid, when available).
I've read this page on the victron site and I thought that all I needed was the multiplus and a cerbo. But then on this pylontech pdf Compatibility List US5000.pdf I saw that there is double asterisk after "off-grid" on the two lines for the multiplus and quattro.
And, as you can see, the note attached to the double asterisk says
"When compatible with Victron Multi/Quattro in off-grid application via venus-device, it is required to have a victron MPPT or other compatible PV inverter with victron to avoid the system getting shut down"
That pdf was last updated on 15/6/2021, so it's not that old.
So, is that correct? Do I actually need an MPPT to use a multiplus as an ups?
Thanks
