4 FAQs about Terms for installation of flow batteries for solar-powered communication cabinets

Can you put a battery in a cabinet?

This document provides guidance for top clearance of valve-regulated lead-acid (VRLA) batteries, which are the most commonly used battery in cabinets. It is also made clear in 706.34 (C) that gas piping is not permitted in dedicated battery rooms. Mixture of a volatile gas in a corrosive location is a recipe for trouble.

How do you calculate the ventilation rate for a battery room?

Calculate the ventilation rate for a battery room consisting of 182-cell battery and 3 battery banks. Assume the battery room has dimensions of 20' (l) x 15' (w) x 10' (h). FC = Float current per 100 ampere-hour. FC varies with battery types, battery condition, and electrolyte temperature. Ah = Rated capacity of the battery in Ampere hours.

What are the requirements for a stationary battery ventilation system?

Ventilation systems for stationary batteries must address human health and safety, fire safety, equipment reliability and safety, as well as human comfort. The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration.

Can a battery be operated in a confined space?

When the battery is operated in a confined space, adequate ventilation should be provided. The battery case is manufactured from high impact ABS plastic resin. It should not be placed in an atmosphere of, or in contact with organic solvents or adhesive materials. Correct terminals should be used on battery connecting wires.
