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.
