Back to Back Mounting

Hi,

I want to mount inverters in a utility room, and use the space effectively. My idea is to construct a steel frame of suitable strength and mount the inverters back to back, as depicted below:

The inverters suck cold air in via the bottom and exhaust hot at the top, slightly angled towards where the wall would typically be. It may exhaust into the neighbour’s air outlet

Is this a workable general arrangement? I can include a separation plate to guide each inverter’s hot stream away.

(For what it’s worth, there will only be one Multi RS per frame for the initial installation. The second one on the back of each frame is for a possible parallel way into the future, if the Multi RS ever supports parallel and I need the extra power)

Regards,
Deon

I have no idea why someone tagged this post as parallel. It has to do this mounting orientation only.

Has anybody mounted inverters back to back?

I’ve never seen it done that way, but I don’t see why it wouldn’t work. As long as you have enough clear space and ventilation. These inverters are heavy so the supporting frame would need to be quite strong.

The RS is quite light, but the frame will be plenty strong enough.

I’m more concerned with the exhaust streams interfering with each other.

Why not something like this ?

Because it is an order of magnitude more expensive than welded square tubing. I’m not concerned with the structural side.

I can’t weld…

I have seen it done in this example from Victron Energy

Thanks. Looks like it back only the MPPTs mounted back to back.
