Description
READY-ASSEMBLED 51.2 V LIFEPO4 SOLAR BATTERY · 16.076 KWH · EUROPEAN SUPPLIER STOCK
A 16 kWh LiFePO4 battery for solar self-consumption and backup-ready systems
SEPLOS MASON-314L-O combines 314 Ah LiFePO4 cells, a battery-management system, active balancing and a colour touchscreen in one upright low-voltage cabinet. Its 16.076 kWh nominal energy can store daytime photovoltaic surplus for evening consumption or support selected backup circuits when it is paired with a compatible inverter. The inverter, installation and commissioning are separate project components.
The cabinet has wheels and a telescopic pull handle for controlled positioning before electrical connection. It is not a portable power station and must not be moved while operating. Once installed, the 121 kg battery belongs on a stable, non-combustible surface in a dry, ventilated technical area.
Why choose SEPLOS MASON-314L-O?
16.076 kWh in a single cabinet
A single 51.2 V / 314 Ah pack provides substantial energy capacity without building a battery from loose cells. Capacity and inverter power remain separate design values: the battery stores energy, while the selected inverter determines AC output and operating modes.
Pull handle and wheels simplify positioning
The trolley-style cabinet is easier to move into its final service position than a plain 121 kg enclosure. The handle and wheels help with indoor positioning only; suitable lifting equipment, a safe route and secure final placement are still required.
Colour touchscreen for local status checks
The front display gives the installer a convenient local view of battery status.
Active balancing for large 314 Ah cells
The supplied specification describes an active-balancing board capable of operating up to six channels at 2.5 A per channel. Active balancing helps manage cell-voltage differences, but it does not replace correct settings, matched cells or professional commissioning.
CAN and RS485 communication
The BMS communicates through CAN and RS485. Integration uses an inverter with a matching BMS protocol, firmware and communication-cable pinout.
Model-specific technical and conformity documents
The available document set names MASON-314L-O directly and includes the specification, an EMC conformity certificate and report, an EN 62619:2022 conformity certificate and a RoHS conformity certificate. Each document applies to the model and submitted sample or revision identified inside it.

Selecting a compatible inverter
MASON-314L-O is intended for a compatible low-voltage battery inverter or hybrid inverter. CAN or RS485 is only the physical communication layer; the correct protocol, firmware and pinout are equally important. Send us the inverter manufacturer, exact model, firmware where available, required backup mode and planned number of battery packs.
Do not connect photovoltaic strings directly to the battery. DC cables, isolation, over-current protection, earthing and inverter settings must be designed for the complete system. Parallel operation should use matching packs with compatible firmware and appropriate state-of-charge preparation.
Plan the storage from real energy use
A 16 kWh battery can shift a meaningful share of daytime solar production into the evening, but it does not guarantee whole-building backup or a particular runtime. Actual use depends on reserve settings, conversion losses, temperature, battery current limits, inverter power and the connected loads.
WodaTherm™ can help you select battery capacity and inverter power for your photovoltaic system and expected consumption.
Installation, handling and safe operation
Professional installation and commissioning are required. Place the battery upright on a stable, non-combustible surface in a dry, ventilated technical space, maintain the prescribed clearances and protect the terminals and cables against impact. The wheels and pull handle are positioning aids, not permission to operate or transport a connected battery.
European stock, freight and commercial scope
This model is supplied from European warehouse stock; dispatch and freight timing are confirmed with the order. Heavy-goods delivery requires suitable access and a safe unloading point.
The product is the assembled battery pack described here. A compatible inverter, site cabling, switchboard work, lifting, installation and commissioning are not included unless expressly listed in the quotation.
