Guidelines for Construction of Generator Enclosures

If you want to protect your portable generator from the effects of weather, wildlife, and theft, it is necessary to protect it, but why buy a casing and baffle box when you can make it yourself? This article will provide you with a simple and direct guide to building generator casings.

What do you need

Tape measure

3 louvered ventilation openings

Aluminum plate

2.5cm deck screws

Bungee jumping rope

Vertical saw

0.6cm and 0.6cm machine screws

Woodworking pencil

1.27CM plywood (depending on the size of the generator)

8 L-shaped brackets

Sealing agent for joint filling

1.27cm hardwood railing (length you need)

Design casing

When sketching the chassis, it is important to design it to discharge exhaust gases and heat, and note the location of the exhaust device, cooling fan, temperature monitoring system, ventilation holes, and any other cooling features you may want to add. Similarly, it is wise to leave a space of 5-7cm between the generator and the baffle box.

Top panel

Firstly, based on the overall top dimensions, including a margin of 5-7 centimeters, cut 1.27 centimeters of plywood with a saw.

Next, measure and cut two 1.27cm railings according to the length of the top plate, and then cut two more railings according to the width.

Finally, fix these railings to the top plate with deck screws.

Front and side panels

The front panel should be on the same side as the engine intake, and the rear panel should be around the exhaust port. However, their construction is the same.

Firstly, cut three pieces of plywood (two sides and one side) based on the dimensions of the side and front.

Next, measure the size of the louver vent on the plywood. Mark the rectangular outline with a carpenter's pencil. Then, use a vertical saw to cut the groove. To make it easier, use an electric grinder to drill holes in the contour and then cut.

Finally, use screws to secure the vent to the side panel and tighten it.

Rear panel

This is the most complex part as it is located in a location related to the exhaust system.

You need to make the length of the rear panel slightly less than half of the front panel. The aluminum waterproof board will occupy the remaining space. This paper should be slightly larger than the wood on the back panel.

Afterwards, fix the aluminum plate to the back panel with machine screws.

Assembling panels

Firstly, use deck screws to secure the four panels to the top panel crossbar. Connect the L-shaped bracket to every corner, ensuring that everything is at right angles.

Next, seal the porous edge sealant.

Finally, wrap your casing around the generator with a rubber band to prevent it from being blown away by the wind.

Alright, enjoy your DIY generator casing!
