STECO GRANIT A Series: Powering Industrial Systems with Advanced Lead-Acid Technology

When Reliability Meets Innovation: The GRANIT A Series Advantage

Imagine running a hospital's emergency power system during a blackout, where every second of uninterrupted electricity literally holds lives in balance. This is the real-world scenario where STECO's GRANIT A Series batteries demonstrate their engineering prowess. As part of STECO Group's premium gel lead-acid battery lineup, these 2V industrial powerhouses combine German precision with French engineering flair to deliver exceptional performance in mission-critical applications.

Core Technical Specifications That Matter

Voltage & Capacity: Available in 2V configurations with capacities ranging from 200Ah to 1000Ah (GRANIT A200 to A1000)
Cycle Life: 1,500+ deep discharge cycles at 80% DoD - 3× longer than standard AGM batteries
Temperature Tolerance: Stable operation from -30°C to +60°C without capacity fade
Recharge Efficiency: 95% energy recovery rate with 8-hour fast-charge capability

Industrial Applications Redefined

Unlike consumer-grade batteries that shy away from tough environments, the GRANIT A Series thrives where others fail. A recent case study at a Siberian mining operation showed these batteries maintaining 92% capacity after 18 months in -25°C conditions - outperforming competitor models by 40%.

Key Market Segments Served

Telecom infrastructure backup systems
Railway signaling and traction power
Off-grid solar/wind energy storage
Industrial UPS and DC power systems

The Gel Technology Edge

STECO's proprietary gel electrolyte acts like a molecular sponge - immobilizing the acid while allowing efficient ion transfer. This design eliminates electrolyte stratification issues common in flooded batteries, achieving 99.99% recombination efficiency. Compared to standard VRLA batteries, the GRANIT A Series shows 30% lower internal resistance, enabling higher surge currents when your systems need it most.

Maintenance Features That Save Costs

Zero electrolyte top-ups required
3-year water loss warranty
Patented pressure relief valves prevent case deformation

Global Compliance Meets Local Support

With certifications including IEC 60896-21, UL 1989, and ISO 14001, these batteries meet the strictest international standards. STECO's Chinese service network through Beijing Lusheng Power provides localized technical support - a key differentiator when dealing with complex industrial installations. Their field engineers recently completed a 48-hour emergency battery replacement for a Shanghai metro project without disrupting train schedules.

Future-Ready Battery Architecture

The modular design allows capacity expansion through parallel connections - a feature that helped a Malaysian data center scale its backup power incrementally as server loads increased. With optional IoT-enabled monitoring modules, operators can now track cell voltages and internal temperatures in real time through SCADA integrations.

FAQS about Photovoltaic panels series connection method diagram

What is a wiring diagram for solar panels?

At its core, a wiring diagram for solar panels shows the connection between the different components of a solar power system. This diagram illustrates how solar panels, charge controllers, batteries, and inverters are interconnected to ensure a seamless flow of electricity.

How to wire solar panels in parallel or series?

Connect the negative terminal of the first panel and the positive terminal of the second panel and connect to the corresponding terminals in solar regulator’s input. The solar regulator will detect the panels and start to charge the battery during sunlight. Wiring solar panels in parallel or series doesn’t have to be an either/or proposition.

How do you connect solar panels together?

Connecting PV modules in series and parallel are the two basic options, but you can also combine series and parallel wiring to create a hybrid solar panel array. Some solar panels have microinverters built-in, which impacts how you connect the modules together and to your balance of system. What Are They?

How do you connect solar panels in series?

To connect solar panels in series, you need to wire a group of panels in line by connecting from positive to negative poles. This setup boosts the array’s voltage while maintaining the same amperage, allowing you to stack voltage output across your solar panel system.

What is series wiring for solar panels?

Series wiring is typically done for a grid-connected inverter or charge controller that requires 24 volts or more. Solar panels are similar to batteries in that they have two terminals: positive and negative. A series connection is made by connecting the positive terminal of one panel to the negative terminal of another.

What is a series connected PV module?

The entire string of series-connected modules is known as the PV module string. The modules are connected in series to increase the voltage in the system. The following figure shows a schematic of series, parallel and series parallel connected PV modules. PV Module Array To increase the current N-number of PV modules are connected in parallel.
