In an inverter system, batteries play very important roles. First, they provide the needed DC that will be converted to DC for use in appliances. And second, in off-grid situations, they help store excess electricity generated from solar panels for use at a subsequent time.

Differences Between Tubular and Flat Plate Technologies

While all batteries have essentially the same components, electrolytes, terminals, and separators integrated into 'cells', they are often differentiated based on either the nature of their most basic component, their electrolytes, or their plate technology. Based on their plate technology, OPzV batteries can either be Flat Plate or Tubular.

The definitive features of the OPzV batteries are the multi-tube bag gauntlet and increased surface area of the positive plate.

Due to increased positive plate surface area, tubular batteries have 20% more electrical capacity than flat plate batteries of comparable size and weight. With less positive plate shedding, tubular batteries also provide up to a 30% longer service life than OPzV batteries. Generally, tubular batteries are preferred of the two types of batteries.

Based on the nature of their electrolytes, batteries can either be

1.      Flooded Lead Acid (FLA)

2.      Valve Regulated Lead Acid (VRLA)

Flooded Lead Acid and Valve-Regulated Lead Acid

Flooded lead-acid (FLA), is the traditional battery technology. As the name implies, the liquid electrolyte in the battery is in liquid form. OPzV batteries require constant maintenance checks which may be a heck to some people.

VRLA batteries are batteries constructed to eliminate the need for constant checks and to eliminate the emission of fumes or gases continuously and the attending dangers. To remove the need for constant maintenance, they are adjusted in these three ways:

1. FLA batteries have openings at the top from where distilled water is to be added for maintenance and safe running. This can be sealed off and replaced with a self-regulating valve.

By holding the acid electrolyte in glass mats, as opposed to freely flooding the plates. A battery constructed in this way is called OPzV batteries.

By making the acid electrolyte into a gel-like liquid. This is done by adding silica dust to the electrolyte, forming a thick putty-like gel. A battery constructed in this way is called a Gel Cell battery.

OPzS and OPzV batteries are both types of tubular-plated batteries. The differences are like their electrolytes. While the acid electrolyte of OpzS is FLA, the OPzV batteries are VRLA. Its electrolyte is made into a gel by the addition of silica dust. Hence, they are also referred to as "silicone batteries". Also, the OPzV batteries are valve-regulated, sealed, and thus, maintenance-free.


They have a cell voltage of 2V and have to be connected in series to produce higher voltages. Also, they are differentiated from the other types of batteries by their upright and vertical orientation.
