The 1stess WYLD51.2V314AH is a floor-standing LiFePO4 solar storage battery with 51.2V nominal voltage, 314Ah rated capacity and 16.076kWh rated energy. It offers importers, EPC contractors and solar installers a specified battery option for residential energy storage, villa backup power and small-farm solar projects.
This 51.2V 314Ah lithium iron phosphate battery features a front LCD, control buttons, a metal cabinet, a recessed side handle, ventilation grilles and floor-standing support feet. The supplied dimensions are 740 × 395 × 250mm, with a battery weight of 115kg.
Built-in BMS functions include overcharge, overdischarge and short-circuit protection. The technical table specifies at least 5000 cycles, 150A standard charging current and 150A standard discharge current. Maximum charging voltage is 57.4V; minimum discharge voltage is 43.2V. Cycle-life test conditions should be checked in the final datasheet.
RS485 and CAN communication support integration review with a selected solar inverter. Confirm battery voltage, inverter model, communication protocol and charge settings before specifying the system. Solar self-consumption, backup and off-grid operation depend on the matched inverter and complete system design.

Specify a 51.2V 314Ah LiFePO4 battery for a residential solar storage design. Its rated energy is listed as 16.076kWh. Usable energy and backup duration depend on operating settings, connected loads and the matched inverter.
Review the front LCD and controls, recessed side handle, two side ventilation sections and metal support feet. Include the 115kg weight and cabinet dimensions in the installation and handling plan.
The supplied specifications list overcharge, overdischarge and short-circuit protection. Confirm the selected inverter's charging settings against the 57.4V maximum charging voltage, 43.2V minimum discharge voltage and 150A standard charge/discharge currents.
Provide the intended inverter model and communication requirements. Confirm the protocol and configuration before ordering; RS485 and CAN interface names alone do not establish compatibility with every inverter.
For importer and EPC enquiries, share your target market, project quantity, installation location, inverter model and branding requirements. Request current specifications, model-specific compliance documents, lead time and a project quotation.





16kWh is the product's marketed energy class. The supplied technical table lists rated energy as 16.076kWh. Usable energy depends on the system's operating settings and losses.
The specified nominal voltage is 51.2V. Buyers looking for a 48V-class lithium solar battery should check the inverter's supported voltage range and communication protocol for this exact model.
Compatibility must be checked for the selected inverter model, supported battery voltage, communication protocol and charge/discharge settings. Send the inverter model to 1stess for review before procurement.
Provide the destination market, battery quantity, inverter model, application, requested delivery date and branding requirements. Ask for the latest datasheet, packing information and model-specific compliance documents.
