The 15.36kWh nominal capacity provides substantial energy storage for photovoltaic self-consumption, nighttime household loads and backup-power applications.
Solar Self-Consumption & Backup
| Daytime Solar PV supplies household loads and stores surplus energy in the battery. | Evening Stored solar energy can support household consumption after photovoltaic production falls. | Grid Outage A compatible backup inverter can use battery energy to support selected household loads. |
Smart BMS Protection
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Temperature protection
- Cell voltage monitoring
- Cell balancing
- SOC and battery operating-status management
Inverter Communication
Correct communication between the battery BMS and inverter is essential for reliable residential energy-storage operation.
| CAN | Available According to BMS Configuration |
| RS485 | Available According to BMS Configuration |
| Inverter Protocol | Confirmed According to Inverter Brand and Model |
Battery-Only ESS Architecture
This product is positioned as a battery energy-storage unit. Hybrid inverter, MPPT solar charger, AC transfer equipment and photovoltaic modules are supplied separately unless specifically included in the confirmed project configuration.
Expandable Energy Storage
Multiple battery units can be engineered for higher-capacity residential ESS projects when the BMS, inverter protocol and parallel-system architecture support multi-battery operation. The maximum number of parallel batteries is confirmed according to the final system design.
Typical Applications
| Home Solar Storage Store surplus photovoltaic energy for evening and nighttime household use. | Home Backup Power Battery energy for compatible inverter-based backup systems during grid interruptions. |
| Off-Grid Homes High-capacity storage for homes relying on photovoltaic and other renewable-energy sources. | PV Self-Consumption Increase local use of solar generation instead of exporting all surplus energy to the grid. |

Frequently Asked Questions
The 51.2V 300Ah battery provides 15.36kWh of nominal energy.
The standard configuration is a battery energy-storage unit. A suitable inverter can be supplied separately according to the project.
CAN or RS485 communication can be configured, but compatibility must be confirmed from the inverter brand, model and required battery protocol.
Parallel expansion can be supported according to the final BMS and inverter architecture. The approved maximum number of batteries must be confirmed before installation.
Runtime depends on usable battery energy, inverter efficiency and the average household load. Provide the expected loads for an accurate backup-time calculation.
Please provide the inverter model, solar-system size, household average and peak load, required backup time, communication protocol, installation conditions and required total battery capacity.
