I'm going to install my Victron II, 2x120 inverter charger where my sofa bed is (rear of RV) to save putting so much weight up front. I'm putting 4 eg4 v2, 24v batteries, 200 amps each into this system. I'm putting 8 24v, 200 watt solar panels on the roof, for a total of 1600 watts. running them in (2s4p). I think that means 2 strings of 4 panels each, paralleling 4 panels on each string. Each string will be on it's own solar charge controller. This design will NOT be powering the 12v systems, since it gets power from a Intel-power 120v to 12v @ 80amps plus 2x12v batteries. I'm leaving this system alone, and I know it's not the efficient way.... I'll move the Surge Guard from the front bay to the rear and hook it into the shower power that I'll bring up through the floor, out of the power cord real box and power the AC side of the Victron unit. I'll use the existing AC cables to power the RV. I hope I made sense?
I would like to stick with Victron products so the can communicate with each other but I see a design flaw with the Victron Lynx products. If using the Lynx power in with, the Lynx smart shunt, with the Lynx Distributor, you are pulling negative and positive battery power from the #1 battery first. My thoughts are to use the Lynx power in to connect the batteries along with the Lynx Distributor. I can then pull DC power off the opposite side of the Lynx power buss bar and install a inline shunt. The Lynx Distributor gives me the ability to fuse my power leads to the inverter/ charger and fuse my solar in. The Multiplus-II 2x120 manual suggests 2x1/0 cables to power the unit with a 400 amp fuse? Would that be 2x200 amp fuses on each cable?
My next problem is what size of Victron shunt do I use with this configuration? I have the potential of 800 amps at 24v, so do I need a shunt capable of passing 800 amps through? Or since the Inverter is fused at a max of 400 amps will the 500 amp shunt work?
I could keep going on but I think this hits all the key points, any input will be appreciated, thanks.
