Technology & product summary

One LiFePO₄ platform, sized from a bedroom closet to a substation yard.

Green Image Tech builds a single lithium iron phosphate storage architecture — shared cell chemistry, BMS logic, and fire-safety design — packaged across six product families that scale from a 5 kWh wall unit to a 5 MWh container.

The platform, to scale

Six product families across three orders of magnitude

Every family is built from the same LiFePO₄ module and battery-management design; what changes is packaging, IP rating, and how many modules run in parallel. Bars show each family’s deployable range, from its smallest single unit to its largest listed configuration.

Underneath every tier

The technology shared across the whole platform

LiFePO₄

Cell chemistry

Lithium iron phosphate across every family — chosen for thermal stability and long service life over energy-dense but less forgiving chemistries.

BMS

Smart battery management

Multi-layer protection against over-current, over/under-voltage and over-temperature, with cell balancing and auto-networking for parallel packs.

Fire

Active suppression

Smoke and combustible-gas detection with aerosol or water-immersion suppression, plus explosion-proof venting on cabinet and container tiers.

−20 – 60°C

Operating range

Full-range charge/discharge performance from arctic garages to desert substations, with automatic derating above 45°C on utility hardware.

IP20 – IP67

Enclosure ratings

Indoor cabinet through fully submersible-rated container, so the enclosure matches the install site instead of over- or under-building it.

WiFi · BLE · CAN

Monitoring & control

Local Bluetooth commissioning, WiFi app monitoring, and CAN/RS485/TCP-IP for BMS-to-inverter and fleet-level EMS integration.

Certifications & compatibility

Built to the standards installers ask for

UL1973 UL9540 UL9540A CB-IEC62619 CE-EMC UN38.3 NFPA 69 UL3536 MSDS
Inverter-agnostic by design. The wall and floor-standing lines are broadly compatible with 50+ hybrid inverter brands — including Lux Power, Sol-Ark and MEGAREVO — so a system can be specified around the inverter a site already has.
