Power Vent for Battery Boxes


Power Vent                                                                                                                                    

Battery Bank Ventilation
Ventilates hydrogen that's naturally generated through the charging of your battery bank. Prevents dangerous build up of explosive hydrogen gas. Uses very little power. Guaranteed for 4 years. Choice of 12, 24 or 48V DC models.

The POWER VENT was designed for use in remote home power systems. The concept arose from field experience of systems with enclosed battery boxes. 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.

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. During these times the battery box is force vented with a low power, sparkless fan which overcomes the damper sending the gas outdoors. The "fan on" mode is determined by the battery voltage. When the batteries are "gassing" during charge periods the battery voltage will read above normal. A voltage sensitive switch is required in the system to make the on/off determination. All TRACE SW model inverters have a programmable auxiliary relay which can operate the POWER VENT. Other systems require the addition of a voltage controlled switch.
