Product Documents
FAQs
How much energy does the LS51314 store?
The LS51314 is rated at 51.2V and 314Ah, providing approximately 16.08kWh of nominal energy. Actual usable energy and runtime depend on system settings, inverter efficiency, depth of discharge, temperature, and the connected loads.
How many LS51314 batteries can be connected in parallel?
Current LS51314 product materials specify support for up to 16 batteries in parallel, providing approximately 257kWh of nominal storage at the maximum supported quantity. Parallel systems must follow the current LS51314 manual and use approved cables, protection devices, communication settings, and commissioning procedures. Do not mix different battery models or unapproved configurations.
Which inverters are compatible with the LS51314?
The LS51314 uses the Pylontech protocol by default and supports CAN and RS485 communication. Compatibility must still be confirmed for the exact inverter model, firmware version, communication cable pinout, battery profile, and system configuration. A compatible brand name alone does not confirm that every model will communicate correctly.
Does the LS51314 support closed-loop inverter communication?
Yes, the LS51314 supports closed-loop communication with compatible inverter systems through CAN or RS485. Correct protocol selection, cable wiring, inverter settings, battery addressing, and firmware are required. Confirm the complete communication setup before commissioning the system.
What can I monitor through the VolTrust app?
The VolTrust app can display key battery information including current, temperature, voltage, power, state of charge, NTC readings, and individual cell voltage. Available data and connection range may vary with the phone, app version, installation environment, and battery settings.
What protection is built into the 300A BMS?
The integrated 300A BMS monitors overcharge, overdischarge, overcurrent, short-circuit, and high- or low-temperature conditions. It also supports cell balancing. The BMS is an internal protection layer and does not replace correctly sized external overcurrent protection, disconnects, grounding, cabling, or other equipment required by the system design and local code.
What does active cell balancing do?
Active balancing transfers energy between cells to help maintain more consistent cell voltage with less energy loss than conventional passive balancing. This supports stable pack performance and helps preserve usable capacity, but it does not eliminate the need for correct charging, temperature control, and system maintenance.
How long can one LS51314 power my home?
Runtime cannot be determined from battery capacity alone. One LS51314 stores approximately 16.08kWh of nominal energy, but actual runtime depends on usable depth of discharge, inverter efficiency, standby consumption, appliance startup surge, temperature, and the loads operating at the same time. A qualified system designer should calculate runtime from your measured or nameplate loads.
Where can the LS51314 be used?
The LS51314 is intended for compatible stationary energy storage systems, including selected grid-connected, off-grid, home backup, solar, and telecom applications. The inverter, charger, mounting location, environmental protection, electrical protection, and local permitting requirements must be matched to the intended installation.
Can I install the LS51314 myself?
The LS51314 is a high-energy stationary battery and should be installed and commissioned by a qualified professional familiar with LiFePO4 storage systems. The installer must verify cable sizing, polarity, torque, grounding, overcurrent protection, disconnects, communication wiring, inverter settings, mounting, ventilation, clearances, and applicable electrical and fire codes.
What warranty does the LS51314 include?
The LS51314 includes a 5-year limited warranty, subject to the current VolTrust warranty policy, proof of purchase, proper installation and use, and technical review. The “10 Years Service Support” shown in product materials refers to service support and must not be interpreted as a 10-year product warranty.
Is local warehouse pickup available?
Local pickup may be available for approved orders. Contact support@voltrust.com before placing or collecting an order so the team can confirm product availability, the correct U.S. warehouse, pickup time, required documents, and any applicable shipping adjustment. Do not arrive at a warehouse without confirmation.
