Correct me if I am wrong, as I am a bit new with my SA orange and my growatt spf6000t dvm off grid.. I have 3 lifepo4 bats, bms controlled, I have the growatt to the SA, the master battery bms to the SA and the Gen connected to the Growatt.. Now I am waiting on my EG4 chargeverter to arrive will be several weeks, but here is what I am thinking.
A. I will disconnect the Gen from the Growatt,
B. Connect the EG4 Charger to the Battery Bus of the Growatt,
C. Now with that Config, the SA should show the EG4 Charger as the Grid value on the SA screen, just as the Growatt does.
Lets say it is night time or evening or daytime No Sun, dark cloud cover so no PV, batteries are at SOC by 4 pm 60%, I put Gen online
using the EG4 Charger connected to the Growatt battery bus terminals.. which are already connected.. I turn on Gen and turn on EG4,
SA should show Grid and Charging,
D. Lets say shortly after the Sun Breaks out strong and the PV is showing 2000 watts PV and house is pulling 10 amps, the PV will be total
is giving 29 amps, the Growatt give the 10 amps to the house, and the other 19 amps to the batteries, and with the EG4 Charger online
say I have it set for 60 amps max, limit charge.. the SA should read the total to the batteries, as 79ams, Grid on SA shows 60amps and
if I remember the Growatt behavior it will just give the house AC 10 amp and the EG4 charger will show Batteries charging with 60 amps
TTL, and since the BMS is RS485 communicating with the SA, it will show what and how much each batterie is being feed out of the 60a.
I am only guessing based on what I currently see with what I have now..
Maybe someone can shed some light and correct my theory.. some is actual some is theory until I get mey EG4 Charger.. thanks in advance for replies - Ric
