Low Multiplus AC output voltage

I recently installed a 12/3000/120-50/120V Multiplus , BMV 712, a Digital Multi Control GX panel, 2 MPPT 100/30 solar chargers, a couple battery protects (100 amp on solar side and 200 amp on inverter side) along with 2 x 560 watt solar panel arrays and 2x 200 AH LiFe Blue batteries in my RV. I was able unable to get my computer to find a port to configure the Mulitplus so is used DIP switches. Step 1 switches are as follows : D8 off, D7-D3 are on and D2 and 1 are off for step 1. Step 2 switches are as follows: D8 is off, D7 is on, D6 is off, D5 and 4 are on, D3 through D1 are off. Everything seems to be working fine except when the Inverter initially kicks in, it puts out 120V (as it should) for a few seconds then drops the output voltage to 60 V. Any ideas how to remedy this problem? Thanks.

DS5

off = AES Off

on = AES on

Please keep DS5 off.

Pierre, have you connected a load to AC Out 1? I installed my Multiplus, turned it on, checked the voltage on AC Out 1 and it was under 20v. I connected a load to it and the voltage went up to 120v.

Pierre,

My inverter had de same problem, it went grom 220 volt to 124 volt. The problem was that the AES SOLAR mode in the software was activated.
