Hallo @Nellis.Theron
It might be that the voltage detected from the inverter is lower than 47.5V while the kettle is turned on.
Are you making use of the inverter settings (29=47.5V) as your Back to grid?
Are you making use of the inverter to detect when to switch from solar to grid or are you using ICC battery monitoring software?
If you only use the inverter to detect the voltages to switch you may have to drop the "Back to Grid voltage" lower.
Have a look at the Voltage trend to see if it is the case.

Hi all
My current settings are:
10) Aut
16) SbL/UdC
23) bYd
I went to change these settings to the settings as proposed by Weber and immediately the inverter went into Bypass mode. (I'm currently drawing from the batteries as it is night and my batteries are still on 74%SOC.)
I'm happy with the way my inverter is operating (Except for PV current dips and Freezes) as I'm in any case not totally off grid at the moment.
My batteries are fully charged in the afternoons and then as the PV falls away the batteries supplement the load until the PV drops of completely. I then run on batteries up to about 02:00 the next morning when it changes back to grid with the SOC trigger of 50%.
While running on the grid, my batteries are charged by the 2A from grid and as the PV picks up during start of day, all the PV power is also bumped into the batteries until the batteries reach 70%SOC. At this time (+- 11:00) the Solar/Batteries take over from the grid and all additional power not used by the load are dumped into the batteries. Most of the time the batteries will reach 100%SOC before the end of the day.
My current settings are:
01) Sbu
02) 80A
05) USE
06) Ltd
07) ttE
09) 50
10) AUt
11) 2A
12) 45V
13) 52V
16) Sbl/UdC
18) bOF
19) ESP
20) LON
22) AOF
23) bYd
25) Fd5
26) 52.4V
27) 50.6V
28) SIG
29) 44V
32) AUt
33) Ed5
34 to 39) default (Not in use due to 33 disabled)
40) Nrt
93) Nrt
If you see anything strange with the settings that might be an issue please feel free to comment on it.
Hopefully it will help someone struggling with some other issues.
 
 

Hi @Ant and @miles the KIng will always charge the batteries with Utility while Utility is available. The best to do is to set the charge rate at 2A and live with it.
Therefore set Setting # 11 to 2A.

Hi Guys
just a quick update. After a PV freeze on Friday i changed my bulk charge To 54.8V and float charge to 54.0V. 
The system did not freeze for Saturday and Sunday. Will monitor in the coming week as well. 
The pv dip momentarily still happens when load is added or taken away. 
Greetings
 

Hi, on getting a parallel setup going..
After everything is connected correctly, ensure the inverters are switched off at their switches.  Now apply PV power to them so they can wake up (they will start charging as well).  Now go one by one and set the parallel setting to PAL  (assuming single phase).  Once done for all inverters, start switching them on one by one.  Wait for the AC out to come online on the first one before switching on the second one etc...
Note, the PAL setting can ONLY be set when the inveter is "awake" and switched off.  That state is only possible with PV power connected in an off grid setup.  If your PV is not yet available, you can get to this state when you apply battery power but you have to get into the menu quick as it will turn off again if there is no PV detected.
Hope that helps.
O, and if you did all this and you still have issues I have seen that it was required to turn them all off (disconnect battery) and power back on again.  I only had that scenario twice in many many installations and can't say why it happened.
