Product overview
A 8S1P low-voltage LiFePO4 battery for residential solar storage, home backup and off-grid system projects. The SUNEVER TD-7.5 provides 7.68 kWh nominal energy with 200 A standard continuous current and a 300 A optional configuration.
7.65 kWh nominal energy • 25.6 V nominal voltage • 300 Ah capacity • LiFePO4 chemistry
Specify the complete system
Match the battery voltage range, current rating, communication protocol and protection equipment to the inverter. The standard continuous-current configuration is 200 A; the optional 300 A version must be specified in the order.
Plan expansion with compatible equipment
The published parallel limit is up to 16 units. At 7.68 kWh per unit, 16 units represent 122.88 kWh nominal installed energy. Supported unit count, wiring and commissioning depend on the inverter and the confirmed system design.
Application images show illustrative installations. Inverter, solar panels and other system equipment are not included unless specified in the quotation.
Battery structure
The battery uses a 8S1P LiFePO4 cell configuration inside a floor-standing enclosure. The structure image is a conceptual illustration of the cell group, management electronics and enclosure; it is not a factory assembly drawing. Internal layout and component appearance may vary.
Display and communication
A 4.3-inch touch screen provides a local interface. RS232, RS485 and CAN communication are available for compatible system integration. Match the inverter protocol and battery settings during commissioning.

Frequently asked questions
Are the inverter and solar panels included?
This listing describes the battery. Solar panels, inverter, protection devices and installation materials are separate unless included in the confirmed quotation.
Does it provide power during a grid outage?
Backup operation requires an inverter with an appropriate backup or off-grid function, correct wiring and commissioned settings. The battery alone does not supply household AC power.
Is 300 A standard?
No. Standard continuous current is 200 A. A 300 A configuration is optional and must be confirmed when ordering.
How many batteries can be connected in parallel?
Up to 16 units can be connected in parallel. Confirm the supported configuration with the selected inverter and use correctly rated cabling, protection and commissioning procedures.
What does the cycle-life rating mean?
The published rating is more than 6,000 cycles at 25 °C and 80% depth of discharge. Actual service life depends on temperature, cycling and operating conditions; this figure is not a warranty duration.
Can it be installed outdoors or charged below freezing?
Choose a protected installation location. Contact us to confirm the enclosure rating and separate charging and discharging temperature limits for your site, especially for use below 0 °C.
How long will it power my home?
Runtime depends on usable battery energy, conversion losses and the loads being supplied. A site load assessment is needed; a fixed whole-home runtime cannot be guaranteed from nominal capacity alone.
What should I send for a project quotation?
Send the destination country, quantity, inverter make and model, expected loads and required current configuration. Model-specific certification documents, warranty terms and shipping arrangements can then be confirmed for the order.
Contact us with your inverter model, application and quantity to confirm the configuration for your project.
