I use an AimsPower PSW 1000 watt and it has a remote switching feature. The AimsPower has the lowest idle amp draw of any inverter. I installed a 150 amp ANL fuse and used welding cable for the leads with crimp on Tweco solid copper lugs. Mine is close to the battery bank, in fact, less than 2 feet away. I also used welding cable to interconnect my batteries. Sold by the foot at any welding supply shop and TSC.
The remote is nice, you never have to physically turn off the inverter, just push the buttom.
I would not use a modified sine wave inverter, PSW inverters aren't that much more expensive.
