SiRay Energy
High Voltage Batteries
Put modules in series and the string runs at 153.6 to 768 V. Higher voltage means lower current for the same power, thinner cables and less loss - which is why three-phase homes and light commercial sites go high voltage.

| Model | Modules | System energy | System voltage | Depth |
|---|---|---|---|---|
| GHR-314 | 3-15 | 48.23-241.15 kWh | 153.6-768 V | 233 mm per module |
| GHS-314 | 4-15 | 48.23-241.15 kWh | 153.6-768 V | 278 mm cabinet |
| GHS-280 | 4-15 | 43-215.04 kWh | 153.6-768 V | 278 mm cabinet |
Choosing Between GHR and GHS
GHR-314 starts at three modules and grows to fifteen, in a 233 mm-deep module. GHS-314 and GHS-280 start at four modules and pack the same capacity into a single 278 mm-deep indoor cabinet. Same cells, two ways to build the room.
Integration
CAN bus to the inverter. SiRay high-voltage strings are matched to Growatt, Solis, GoodWe, Sol-Ark, SRNE and DEYE. IP20 - install indoors.

Common Questions
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.
Can I add more battery capacity later?
Yes, if you choose a stackable model. SiRay GLR-200 and GLR-314 accept 2 to 16 modules, taking the bank from 21 kWh to 168 kWh (GLR-200) or from 32.15 kWh to 257.22 kWh (GLR-314) without changing the footprint. High-voltage GHR and GHS strings accept 3 to 15 modules. The SNE-ES wall units parallel up to 16 units for 81.6 or 168 kWh.
