[RE-wrenches] Dual Sol-Ark Inverter 120/240V

[Maverick Brown]

I’ve stacked multiple Radians and I usually use Square D Homeline panels like a HOM1224L125PGCVP. You can easily stack three inverters on the left side bus and local loads on the right side bus. It’s nice to power outlets from all three panels (grid, inverter, generator). If you are super tight on space, the HOM612L100RB can work. Just no main breaker. SQD makes a QO version that has 8/16 and you could incorporate a main/back feed and have room for a couple local loads. 

I’m currently designing my first SolArk that happens to be a double stack. I’m using the homeline panels here as well. 

The inverters and electrical panel mount on a wall above an 8” gutter. 

The downside is that this method can consume a lot of wall space. 

Another method that I have used is to buy a Schnieder Xantrex PDP and use it as the load center. It is expensive! But saves a lot of space when using a Radian with Charge Controllers, etc. (and of course XW stuff). But, I think it is redundant for Sol-Ark.
