SEPLOS MASON-280-N – complete black stackable LiFePO4 storage

This offer is for a complete battery pack with cells, not a DIY enclosure. The current German stock batch uses GF314Ah cells and is stated by the supplier as approximately 16 kWh. The black horizontal enclosure is stackable and intended for professionally designed low-voltage photovoltaic, self-consumption and backup systems.

Confirmed current-stock configuration

• GF314Ah LiFePO4 cells,
• approximately 16 kWh declared by the supplier,
• active balancer,
• integrated aerosol fire-suppression unit,
• cables and accessories supplied with the pack,
• wooden shipping crate,
• 34 units in the German EU warehouse,
• shipping to the Czech Republic charged separately.

Technical data and transparent version distinction

Important datasheet note: the attached official MASON-280 document describes an older/reference 280 Ah, 14.3 kWh configuration. The current item is explicitly confirmed by the supplier as GF314Ah and approximately 16 kWh. We therefore use the older document only as transparent reference for construction, dimensions and reference weight; its 280 Ah / 14.3 kWh capacity figures are not assigned to the current product. The supplier has not yet provided a new 314Ah datasheet for this horizontal version.

Use

The battery stores photovoltaic surplus for later consumption, such as evening or overnight use, a more expensive tariff period, or as part of a backup system. Actual usable energy and available power depend on settings, the inverter, permitted SOC range, temperature and complete installation design.

Inverter compatibility

The model family uses communication interfaces described in the attached documentation, but compatibility must be verified for the exact 314Ah batch, inverter model, firmware, battery protocol and cable. Give us the inverter details before ordering; the presence of a connector alone is not treated as proof of compatibility.

BMS, balancing and safety

The current stock configuration has a confirmed active balancer and aerosol fire-suppression unit. Exact BMS type, current limits, balancing parameters and communication profile must follow the documents supplied with the specific batch. The pack contains hazardous short-circuit energy: do not dismantle it, bypass protection, work on live conductors, or expose it to water, fire, excessive heat or impact.

Installation and commissioning

1. Installation must be carried out by a qualified person according to the design, current instructions and local regulations.
2. Confirm actual handling weight and use suitable lifting equipment; stacking is allowed only as specified by SEPLOS.
3. Verify polarity, DC protection and isolation, conductor sizes, grounding and communication wiring.
4. Configure the inverter and BMS for the actual batch and verify communication, charging, discharging and alarm states.
5. For parallel systems follow the approved topology, equal connection conditions and specified startup sequence.

Package, stock and delivery

The supplier explicitly confirms the pack with cells, active balancer, aerosol fire-suppression unit, cables/accessories and wooden crate. 34 units are in German stock. Freight to the Czech Republic is not included in the product price and is calculated by pallet/freight carrier for the actual shipment. The 112 kg reference weight comes from the older 280Ah sheet; actual shipping weight of the current 314Ah crate will be confirmed before dispatch.

Warranty and documents

The official SEPLOS Warranty Agreement 2026 provides a five-year free warranty. During years 5–10 replacement parts may be supplied without charge, while the buyer pays freight, service and other related costs. This is not a fully free ten-year warranty. The agreement and relevant model-family CE/EMC, IEC 62619 and RoHS certificates are hosted directly on WodaSign and attached to this product.
