Let’s play a quick game. What do data centers, off-grid solar systems, and electric wheelchairs have in common? (No, it’s not their love for coffee breaks). They all desperately need reliable energy storage solutions – enter the Modular Plus Max Range VRLA battery. These sealed lead-acid wonders are quietly revolutionizing how we store power, and I’ll bet my multimeter you’re using technology powered by one right now.
Unlike traditional batteries that require constant babysitting, VRLA (Valve-Regulated Lead-Acid) batteries are the low-maintenance cousins in the battery family. The modular plus max range variant takes this further with:
When TelcoX upgraded their cell towers to modular VRLA banks, something hilarious happened. Their maintenance crews started complaining about too much free time. The batteries kept working through:
Recent data from Energy Storage Journal shows modular VRLA systems outperforming lithium-ion in three key areas:
Cycle Life | 1200+ cycles at 80% DoD |
Cost per kWh | 40% lower than Li-ion alternatives |
Installation Time | 70% faster deployment |
What makes these batteries the Swiss Army knives of energy storage? It’s all about the modular plus max range architecture:
Remember when lithium was the prom king of batteries? A recent hospital backup power study showed:
The latest Modular Plus Max Range VRLA iterations are getting smarter than your average smartphone:
Having deployed 50+ modular VRLA systems, here’s my hard-earned advice:
While everyone obSMesses over lithium recycling, modular VRLA batteries are quietly hitting sustainability home runs:
“But lead-acid needs weekly checkups!” cry the lithium loyalists. Modern Modular Plus Max Range VRLA systems:
Just as PV systems can be installed in small-to-medium-sized installations to serve residential and commercial buildings, so too can energy storage systems—often in the form of lithium-ion batteries. NREL researchers study the benefits of such systems to property owners, their impact on the electric grid, and the. . Energy storage has become an increasingly common component of utility-scale solar energy systems in the United States. Much of NREL's analysis for this market segment focuses on the grid impacts of solar-plus-storage systems, though costs and benefits. . The Storage Futures Studyconsidered when and where a range of storage technologies are cost-competitive, depending on how they're. [pdf]
For solar-plus-storage—the pairing of solar photovoltaic (PV) and energy storage technologies—NREL researchers study and quantify the unique economic and grid benefits reaped by distributed and utility-scale systems. Much of NREL's current energy storage research is informing solar-plus-storage analysis.
At the lowest technology cost point modeled, solar-plus-storage is economical in 10 of the 17 locations and in all of the 16 building types modeled. This suggests that the solar-plus-storage market will grow significantly if solar and storage costs continue to decline as expected in the future.
Technology cost and utility rate structure are key drivers of economic viability of solar and storage systems. This paper explores the economics of solar-plus-storage projects for commercial-scale, behind-the-meter applications. It provides insight into the near-term and future solar-plus-storage market opportunities across the U.S.
Solar-plus-storage shifts some of the solar system's output to evening and night hours and provides other grid benefits. NREL employs a variety of analysis approaches to understand the factors that influence solar-plus-storage deployment and how solar-plus-storage will affect energy systems.
The highest potential for savings was found in California, New York, New Mexico, and Alaska. Across all scenarios modeled, solar-plus-storage systems were most often cost-effective in San Francisco, Anaheim, and Los Angeles. These locations have both good solar resource and relatively high demand rates.
This suggests that, similar to falling technology costs, increasing utility rates will result in a larger number of solar-plus-storage systems, larger system sizes, and increased savings from each system. On average, savings were highest for projects that combined both solar and storage (see Fig. 13 ).
