Use and system sizing
The 16.076 kWh nominal energy stores photovoltaic surplus for later use, for example in the evening, overnight or during a more expensive tariff period. Actual usable energy, charging/discharging power and backup duration depend on inverter/BMS settings, permitted SOC range, temperature, load profile and complete system design. The unit must not be selected from the kWh figure alone.
Verified compatibility with Deye SUN-10K-SG05LP3-EU-SM2
Yes – the SEPLOS MASON-314L-O is suitable for this low-voltage three-phase hybrid inverter. The battery operates from 41.6 to 57.6 V, while the Deye battery input accepts 40 to 60 V. Closed-loop BMS-to-inverter communication is supported over CAN using the Deye / Pylontech CAN-Bus Protocol V1.3.
Installation requires the correctly wired CAN cable, lithium-battery mode and the matching communication protocol in the inverter. The pack’s recommended continuous charge/discharge current is 157 A and its maximum charging current is 200 A. Although the Deye inverter supports a higher current, its battery limits must be configured to the SEPLOS values. Commissioning includes verification of SOC, voltage, current, alarms and CAN-controlled charging/discharging.
Cells, BMS, balancing and safety
The configuration confirmed by the supplier uses 16 GF314Ah LiFePO4 cells in a 1P16S arrangement, forming a 51.2 V / 314 Ah pack with 16.076 kWh nominal energy. Control and protection are provided by an integrated smart SEPLOS BMS 3.0 with CAN/RS485, while a separate active balancer continuously maintains cell balance.
The BMS monitors cell voltages, temperatures, current, SOC and fault states and controls protection against overvoltage, undervoltage, overcurrent, short circuit and unsuitable temperature. The aerosol fire-suppression unit is an additional integrated safety layer. It does not replace correct system design, DC protection and isolation, room fire planning or professional installation. The pack contains high short-circuit energy and must not be dismantled or operated with protection bypassed.
Installation and commissioning
- Installation and electrical connection must be carried out by a qualified person according to the design, SEPLOS instructions and local regulations.
- Allow for 121 ± 3 kg and use suitable handling equipment; the pull handle/lever is not a substitute for safe lifting.
- Verify a stable base, polarity, DC protection and isolation, conductor sizes, grounding and communication wiring.
- Configure the inverter for the correct protocol and limits; after startup verify communication, charging, discharging, balancing and alarms.
- Parallel operation must follow current manufacturer documentation and the approved topology.
Package and shipping
The current supplier message confirms the complete pack, active balancer, aerosol fire-suppression unit, cables/accessories and wooden crate. Its weight and crate require pallet/freight delivery; the Czech shipping charge is not included in the product price and is added for the actual shipment.
Warranty and documents
The official SEPLOS Warranty Agreement 2026 provides a five-year free warranty. During years 5–10 replacement parts may be supplied free of charge, while the buyer pays freight, service and other related costs. This is not a fully free ten-year warranty. The current specification and relevant CE/EMC, IEC 62619 and RoHS certificates are hosted directly on WodaSign and attached to this page.
