how necessary (or not) is battery/inverter communication for solar/backup newbies ?

[JeffB1961]

i have zero solar/backup experience . i'm %99 decided on the victron multipluss ii 48/5000 for my inverter . i'm really liking the vatrer batteries for 900 a pop shipped . they have a display and BT but no communication ports . for a solar virgin is communication a big help or should i be just fine without it . seems like the experienced folks here and on youtube don't care about it or don't want it . sooooo should i be fine with the vatrers or would i be better served with something with communication ? i want to get my batteries/inverter in the next few weeks . i plan to get the victron mppt rs 450/100 and 5000ish watts of panels in a year . i want 4 batteries . it will be used as back up for that year . we used 607 kw of power last month so abour 20kw a day . does 4 batteries seem like enough for that . we're on a ridge line in the appalachian mountians of Virginia with plenty of sun .
thanks , jeff

Voltage controled charging works well and is trouble free with LFP batteries. It is not necessary to have closed loop communications. You may want to add a Victron shunt to the system to get accurate SoC data.

As long as the battery has Bluetooth or WiFi or a display so you have access to individual cell voltages and battery health info for troubleshooting that's all you need.

Battery bluetooth to monitor what's going on with the battery is very useful. All the other system communications is definitely not necessary.

Battery comms are definitely not needed.
