Minimum installation clearances

This action means keeping the free space around an inverter that the installation manual asks for: below it, above it and on its sides. It helps prevent the failure mode Inverter Incorrect Installation, where installers often do not keep the minimum distances to nearby parts. Enough clearance lets heat escape, so the inverter does not overheat or cut its output because it is running too hot. Check the manufacturer's clearance drawing before mounting. Leave extra room on the side where the cooling fans are serviced, and keep space between inverters mounted next to each other or back to back. The clearance under the inverter also has to fit the bend radius of the AC cable and the installation environment. Some manufacturers allow smaller clearances depending on site conditions. In that case you may have to take the inverter off its bracket or the wall to service the fans. The product clearances are only a minimum: electrical codes or local rules may require much larger working clearances. Clearances do not solve every installation problem. If you find one, take the unit down and reinstall it following the procedure, and also avoid direct sun, keep it away from flammable materials, and check temperatures and ventilation regularly.
