Ever tried powering your off-grid cabin with regular car batteries? You'd be changing them more often than your WiFi password. Enter the Solar12-150 VRLA Gel Battery Chilwee - the Clark Kent of energy storage that actually survives daily solar abuse. Unlike its liquid-filled cousins that evaporate faster than morning dew, this gel-based warrior operates maintenance-free for 5-7 years, even when you forget it exists.
While AGM batteries gulp oxygen like teenagers chugging soda, our gel hero plays it cool:
Nigeria's Reeddi Energy proved you don't need Elon Musk money for solar innovation. Their Lagos microgrid using similar Chilwee batteries:
The Solar12-150's secret sauce? Density. Packing 150Ah into a 12V frame thinner than your smartphone. Recent UL tests showed:
Metric | Standard Battery | Chilwee 12-150 |
---|---|---|
Energy Density | 30Wh/kg | 42Wh/kg |
Cycle Life @50% DoD | 500 cycles | 1,200+ cycles |
Chilwee's VRLA design is like that roommate who cleans up after themselves. No water top-ups. No equalization charges. Just set it and forget it. Pro tip: Pair it with MPPT controllers boasting >98% efficiency - your battery will outlast your marriage.
While not officially "smart", the gel matrix auto-compensates for:
With 82% of new solar installations now specifying gel over flooded batteries, the Solar12-150's IoT-ready terminals are ready for:
So next time someone raves about lithium-ion, remind them: For solar systems that need to WORK rather than win spec sheets, gel VRLA batteries like Chilwee's 12-150 are still the OG champions. After all, when's the last time you saw a lithium battery survive a decade in the Sahara?
This report explores trends in battery storage capacity additions in the United States and describes the state of the market as of 2018, including information on applications, cost, ongoing trends,. . This report explores trends in battery storage capacity additions in the United States and describes the state of the market as of 2018, including information on applications, cost, ongoing trends,. . In this report, we provide data on trends in battery storage capacity installations in the United States through 2019, including information on installation size, type, location, applications, cost.

The remaining states have a total of around of 3.5 GW of installed battery storage capacity. Planned and currently operational U.S. utility-scale battery capacity totaled around 16 GW at the end of 2023. Developers plan to add another 15 GW in 2024 and around 9 GW in 2025, according to our latest Preliminary Monthly Electric Generator Inventory.
Two states with rapidly growing wind and solar generating fleets account for the bulk of the capacity additions. California has the most installed battery storage capacity of any state, with 7.3 GW, followed by Texas with 3.2 GW.
This report focuses on battery storage technologies, although other energy storage technologies are addressed in the appendix. Electrical, thermal, mechanical, and electrochemical technologies can be used to store energy. The capacity of battery storage is measured in two ways: power capacity and energy capacity.
