Choosing a SunoraX battery for a Growatt system
All models in the compatibility table above are LiFePO4 low-voltage batteries with CAN, RS485 and RS232 ports. They differ in energy per unit, discharge current, enclosure and how far a bank can grow.
| Battery | Energy | Max. discharge | Cycle life | Installation | In parallel | Warranty |
|---|---|---|---|---|---|---|
| SX-HB16 | 16.07 kWh (51.2 V / 314 Ah) | 200 A / 10.24 kW | 8000 | Floor, IP65; heated version available | Up to 63 | 10 years |
| SX-H-LV51-FS392 | 20 kWh (51.2 V / 392 Ah) | 300 A / 15.36 kW | 8000 | Floor on castors, IP65 | Up to 63 | 10 years |
| SX-H-LV51-W (100 / 200 Ah) | 5.12 / 10.24 kWh | 100 A / 5.12 kW; 170 A / 8.70 kW | 6000 | Wall or floor, IP20 | Up to 15 | 10 years |
| SX-H-LV51-RK100 | 5.12 kWh (51.2 V / 100 Ah) | 100 A / 5.12 kW | 6000 | Rack or wall, IP20 | Up to 15 | 10 years |
| SX-H-LV48-RK100 | 4.8 kWh (48 V / 100 Ah) | 100 A / 4.8 kW | 6000 | Rack or wall, IP20 | Up to 15 | 10 years |
| SX-H-LV51-ST | 5.12 to 20.48 kWh (1 to 4 modules) | 100 to 200 A / 5 to 10 kW | 6000 | Floor or wall, IP20 | Up to 15 | 10 years |
Cycle life as rated in the datasheets: 90% depth of discharge, 25 °C, 0.5C. The SX-H-LV51-ST is supplied to Africa, Latin America and Southeast Asia only.
Sizing the battery bank
- The 51.2 V models share a working voltage of 45.6 to 56.16 V. The SX-H-LV48-RK100 is for systems specified at 48 V nominal (42.75 to 52.65 V).
- Batteries in parallel add their current. Check that the bank’s continuous discharge current covers the maximum battery current in the Growatt inverter datasheet; for example, two SX-H-LV51-RK100 modules provide up to 200 A.
- Size the usable energy from the load the battery has to carry each day, then add units: the floor-standing models scale to 63 in parallel, the wall, rack and stack models to 15.
- Charging is rated from 0 to 45 °C. For unheated garages and cold sites, the SX-HB16 is offered with low-temperature heating.
Battery settings for Growatt inverters
- Connect the battery’s CAN or RS485 port to the inverter’s BMS port.
- Set the battery’s protocol switch as shown in the battery manual for Growatt.
- On the inverter, choose the lithium battery setting with the matching protocol.
- If the battery does not appear, send us the inverter model and firmware version.
Questions
Which SunoraX battery works with the Growatt SPF 6000 ES PLUS?
The SX-HB16 and the other batteries in the table above. The pairing is tested over CAN 500K.
My Growatt model is not in the table. What now?
Send us the inverter model and firmware version. We check the protocol and confirm the pairing in writing before you order.
Do you sell inverters?
No. SunoraX supplies the batteries; installers use the inverter brands they already stock.
Which SunoraX batteries are available for Europe?
The SX-HB16, SX-H-LV51-FS392, SX-H-LV51-W, SX-H-LV51-RK100 and SX-H-LV48-RK100. The SX-H-LV51-ST is supplied to Africa, Latin America and Southeast Asia only.
How many batteries can run in parallel?
Up to 63 for the SX-HB16 and SX-H-LV51-FS392, and up to 15 for the wall, rack and stack models.
