Energy storage is where battery safety matters most and gets discussed least. A home or workshop storage unit sits in a building for years, often unattended, cycling daily. Solid-state energy storage replaces the flammable liquid electrolyte with a solid one — and for a product that lives indoors, that is a different risk profile entirely.
Why the safety argument is strongest for storage
An e-bike battery is charged and watched. A phone is in your hand. A storage system runs in a utility room, a shop back office or a site cabin, cycling every day for a decade. Our solid-state cells pass puncture and cutting testing at 100% non-flammable and non-explosive, with no liquid leakage, fire, smoke or explosion, and they do not swell or vent in high-temperature storage.
Cycle life is the economics
Storage economics are decided by cycles, not by headline capacity. Our solid-state 30Ah LiFePO4 cells exceed 15,000 cycles — roughly twice conventional cells — and deliver 60% longer cycle life at 60°C operation. Over a ten-year installation that is the difference between one system and two.
What a 1–15 kWh system includes
| Element | Specification |
|---|---|
| Capacity | 1 kWh to 15 kWh |
| AC output | Built-in 220V inverter |
| DC output | USB-C PD, QC and 12V |
| Charging input | Mains and foldable solar panel |
| Operating range | -80°C to +140°C |
| Management | BMS with balancing, pre-charge and full protection set |
Off-grid and solar
Foldable photovoltaic panels connect directly for off-grid charging, which makes these systems practical for outdoor work sites, expeditions, mobile retail and backup power where mains supply is unavailable or unreliable. The wide temperature range means an outdoor or unheated installation keeps working through winter.
Where they are deployed
Home backup and load shifting, small commercial and retail backup, workshop and site power, telecom and monitoring cabinets, and mobile applications where a unit is moved between locations. For larger projects the same cells scale into custom system integration.
Frequently asked questions
How long does a solid-state energy storage system last?
Our solid-state LiFePO4 cells exceed 15,000 cycles — approximately twice conventional cells — with 60% longer cycle life at 60°C. For a system cycled daily, that supports a very long service life.
Can a solid-state storage system be charged from solar?
Yes. Foldable photovoltaic panels connect directly to the system for off-grid charging, alongside mains input, with 220V AC inverter output plus USB-C PD and 12V DC.
Is solid-state storage safe to install indoors?
The solid electrolyte is non-combustible and cells pass puncture, cutting and overcharge abuse tests without fire, smoke or explosion, and do not swell in high-temperature storage — a materially different risk profile from conventional lithium-ion for indoor installation.
