My boat was built in 2001 with an inverter, but it was previously removed (not sure why). I'd like to install a new one. The boat is 240VAC/60 Hz, and the 120V loads are roughly divided across both legs. Because of this, I initially assumed that I would need a dual 120V / 240V inverter, but since I'm not finding many options for that, I'm now questioning that assumption. For example, Magnum makes a dual 120V output unit, MS4024PAE: However, I don't believe it's marine-rated (no bonding of N and G), as is their single 120V, MS4024, below -- it adds that relay in the center to do the bonding when in inverter mode. This one is also listed under their marine section, while the PAE model is not. What is the standard approach for powering both 120V legs while meeting ABYC standards? Parallel two 120V inverters? Thanks!
