You could combine the two exhausts into one larger vent. If you need to move more air you can use two vents, but each one must have its' own vent pipe. Can I stack two Power Vents in a row to move more air?Ī.
The difference between the relay activation and deactivation. Two vents may be used for higher volume.Ĭomes in 3 voltages: 12, 24 and 48 Volts DC SPECIFICATIONSĪ. Systems larger than this can produce more hydrogen gas than the expel rate of the POWER VENT which operates in the 5 to 8 cubic foot per minute range. The POWER VENT is designed around typical home power systems with battery banks under 2,200 amp hours and charge rates under 150 dc amperes. Other systems require the addition of a voltage controlled switch. All TRACE SW model inverters have a programmable auxiliary relay which can operate the POWER VENT. A voltage sensitive switch is required in the system to make the on/off determination. When the batteries are "gassing" during charge periods the battery voltage will read above normal. The "fan on" mode is determined by the battery voltage. During these times the battery box is force vented with a low power, sparkless fan which overcomes the damper sending the gas outdoors. The POWER VENT alleviates this condition by keeping a gravity operated damper closed within the vent pipe except at times when the batteries are being charged and producing hydrogen gas. Quite often the NEC required venting was found back drafting, thus cooling the battery bank and lowering its' capacity as well as venting hydrogen gas into the structure. The concept arose from field experience of systems with enclosed battery boxes. The Zephyr POWER VENT was designed for use in remote home power systems. Keeps batteries warmer in cold climates.I’ll take you through all aspects of the build so anyone should be able to put one together.Simple installation with plastic hood to pipe gas into Power Vent The build isn’t very difficult it does however require a little knowledge of electronics and some basic soldering skills.
12v battery box portable#
Nothing better than to have a hot shower after a couple days camping!), blow-up mattresses, charge up my portable speaker and phone, and whatever else that needs power. I use the power pack to run the shower (yes I have a portable, hot water shower. However I will add another step so show you how I did this soon I added these as an afterthought so you won't be able to see them in the images below. You can also charge the battery via a couple of lugs that stick out the side.
Lastly, I added a mains power switch to make sure the battery isn’t drained when not in use. To regulate the power from the panel, I used a solar panel regulator. An 18v solar panel ensures that it is kept charged throughout the camping trip and there is also LED lighting on the side with a dimmer. The battery pack runs off a 12v, SLA battery and has 3 outlets, one 12v cigarette outlet and 2 USB. So, after being inspired by a build my youngest brother did, I decided to build myself a battery pack that would last the whole time I was camping, was portable and also practical. Usually I’d just use the cars 12v outlet but I find this a hassle, especially if you have to charge your phone at night. Camping these days usually means bringing along things that need power.
