Looking for a bit of help. I have the Easysolar 48/5000 with the BYD 13.8 Lithium Batteries.
I have connected a generator to the system for charging the battery. I have two genets one is a 2000w and the other is an 8500w and both are AVR.
Here is my config on the Multi (the 26A is for the big genset i was using 6A for the small one):
System frequency 50Hz
Shore current 26.0 A
Overruled by remote unchecked
Dynamic current limiter unchecked
State of charge when Bulk finished 95.0 %
Battery capacity 270 Ah
Charge efficiency 0.95
Country / grid code standard None: (feeding energy from DC to grid not allowed)
Accept wide input frequency range (45-65 Hz) checked
AC low switch mains off 180 V
AC low switch mains on 187 V
AC high switch mains on 265 V
AC high switch mains off 270 V
UPS function unchecked
Assist current boost factor 2.0
Inverter output voltage 230 V
Ground relay checked
Inverter DC shut-down voltage 47.00 V
Inverter DC restart voltage 51.00 V
Low DC alarm level 53.00 V
Do not restart after short-circuit (VDE 4105-2 safety) unchecked
enable AES unchecked
Enable charger checked
Weak AC input checked
Stop after excessive bulk unchecked
Lithium batteries checked
Use equalization (tubular plate traction battery curve) unchecked
Charge curve Fixed
Absorption voltage 55.20 V
Float voltage 55.00 V
Charge current 26 A
Repeated absorption time 1.00 Hr
Repeated absorption interval 7.00 Days
Absorption time 1 Hr
TAB: Virtual switch
Virtual switch usage Do not use VS
TAB: Assistant Configuration
Two-signal BMS support (size:139)
*) The battery is full when Auxiliary input 1 is open and
the battery is empty when Temperature sense input is open.
*) Force to float and set SOC to 100% when battery full and switch to charger
only when battery empty.
(note: I believe that the second part of the assistant needs to be changed as it would only use float while charging)
I set the config from this page on the Victron website HERE
Total size of all assistants including the required
(hidden) system assistants is: 198
so before I added the assistant the small genset would charge at 700w.
The big genset would charge at 1200w
After adding the Assistant and updating to the config above I got this.
Which is the same but seem to charge faster about 3-4% in 15 minutes.
Sorry could not get the images to rotate even turned one upside down but still uploaded upside down.
All firmware is compatible in the system.
My question is why does it take so long to charge the battery with the latest config and why am i only get 1500w and not 6000w? or is this normal?
Edit: Ok have just been talk to ALPS and noticed that SOC on the multi is switching from 100% to 67% for a second then back to 100%
Any info would be appreciated.
