Leaf Power Wall Build

Welcome to the blog. Been awhile since I posted. I am currently working on a power wall using Nissan Leaf Modules. I have cut out a ply board that will hold the weight of the modules with ease. 3/4 plywood is heavy duty. The wall is a 48 volt unit to use with a 15kW Low Frequency Inverter to power the house completely with both 110 and 240 volts. I have 7 modules in series and then stack those in parallel for a total of 21 modules. This will be a hybrid system to go without out 7.2kW solar array. We have a propane 12kW generator to power the house. So 48 volts bumped up to 110 and 240 volts and up to 200 amps. The leaf modules lend themselves rather well to power walls or power boxes. I have an idea of mounting modules between wall studs in a shed on the north side or east side to prevent soaking up too much heat. When covered they will be fully hidden except for some cooling louvers. I can build an actual wall of these modules and have them mounted securely between the studs two high and still have room to mount a ply cover. Just don't hammer nails into the walls because you will puncture a module if you do without first removing the batteries from the wall.
