I have already installed four MS inverter/chargers in different locations in the country to power computers and servers and they are working trouble-free. All these units are working independently. The system giving the problem is where we have stacked two MS4348PE. It appears that the second (slave) inverter does not respond fast enough assist the master.

On the MS4348PAE I would check the “Threshold Setting” in the ME-RTR. If you set the threshold lower or OFF the Slave will respond faster to help the Master run …

I installed the MS4348PE inverter/chargers in parallel. They work fine but servers turn off and restart whenever there is a power fluctuation. I have turned off search mode and set the system to UPSmode. I however notice that the voltage reading on meters is half the actual voltage..ie it reads 116V instead of 230 V. Please advise.

For the MS4348PE inverters, did the UPS mode fix the problem?  I believe the 110vac readings are a result of some of the meters not being updated by Magnum – …

I have a problem with one of the Magnum RD2624E. It shows ac input voltage too high and yet we installed a voltage monitor which cannot allow more than 260V to reach the inverter. I have measured the voltage three times (whenever the fault has occurred and found it to be 235 volts) Is there a way to adjust the maximum allowable voltage?

The question about the RD2624E might be software. Software version 4.2 had the high Vac input at 260 Vac. In 2011 Magnum changed to V5.4 which raised the  high Vac …
