I want to install a multiplus ii in my food truck only to cover brief moments of high amp inrush due to refrigeration equipment compressors kicking on. I have a champion 11,000 watt inverter generator to be the main source of power and use the multiplus power assist feature.
Looking at the 24v 2 x 120 multiplus ii what other compents will i need to get this system up and running?
Thank you
Anyone available to help with my setup needs?
The Multiplus2 is depending on a battery, so you need a strong battery that allows to deliver the needed amount of power. Then you should be fine.
You need to configure the power assist in the multiplus2, therefore you might need a MK3 interface and a laptop that is running the VE Configure software. The MK3 and the laptop is only needed for the configuration. 
Beyond the Multiplus and batteries you will need cables to connect the incoming power into the multi, power from the multi to your AC panel and cables to connect the multi to the battery as well as fuses and a shut off to make it all safe. As mentioned you will also need the configuration cable. If you desire to monitor it a shunt and a Cerbo/ screen should give you a nice overview of everything. A shunt alone will at least give you the ability to monitor the battery state of charge.
