Battery Energy Storage Systems
From a 10.5 kg box you carry one-handed to a 2.4 MWh container that anchors a mine site. All SiRay storage runs on LiFePO4 cells with a published cycle life, RS485 / CAN to the inverter and, on C&I units, IP54 enclosures with fire suppression.
The Ranges
-
Portable Power Stations - 1 to 4 kWh (3 models)
LiFePO4 boxes for camping, outage backup and mobile work.
Portable Power Stations -
Complete home systems - 5 to 33 kWh (7 models)
All-in-one towers, wall units and free-standing units that arrive ready to run.
Home Battery Storage -
Low voltage, 51.2 V - stackable to 257 kWh (5 models)
Modules that pair with the hybrid inverter you already own.
Low Voltage Batteries -
High voltage, 153.6-768 V - 3 to 15 modules (3 models)
Series strings for three-phase homes and light commercial sites.
High Voltage Batteries -
C&I Storage Cabinets - 112 to 261 kWh (3 models)
Outdoor IP54 cabinets with fire suppression; the GCB units integrate a three-phase PCS.
C&I Energy Storage -
Containerized ESS - 1.2 and 2.4 MWh (2 models)
ISO containers, wired and factory-tested before they leave Suzhou.
Containerized ESS
Mobile Energy Storage on a Trolley
The GMB-5000 carries 5120 Wh on a wheeled IP54 trolley with industrial sockets and 6000 W of PV input, for sites where trenching a cable costs more than the job.

Common Questions
What is the operating temperature range of SiRay storage cabinets?
SiRay C&I cabinets operate from -20 to 50 ℃. The residential GLR and GHR modules charge from 0 to 55 ℃ and discharge from -20 to 60 ℃. The ESS containers operate from 0 to 50 ℃. All outdoor cabinets are rated below 2000 m altitude.
Does SiRay provide installation and commissioning?
Yes. SiRay delivers projects from feasibility through sizing, containerized build, shipping, commissioning and operator training, then provides remote monitoring and maintenance through vEMS 2.0.
How many cycles does a LiFePO4 home battery last?
SiRay residential battery modules are rated for more than 6000 cycles at 0.5C, 90% depth of discharge and 25 ℃, with a 15-year design life. The SNE-ES F30 and SNE-ES F32 use an 8000-cycle cell. The GLC-261 liquid-cooled cabinet is rated 8000 cycles to 70% end of life.
