BUILT FOR REAL-WORLD INSTALLATIONS
A clean, professional fit for residential energy systems.
Floor-standing design, IP65-rated enclosure protection*, and CAN / RS485 communication make POSNBAT straightforward to integrate into residential low-voltage systems. Final installation, cabling, protection, and inverter compatibility must be confirmed for each project.
ONE PLATFORM. THREE CAPACITIES.
Build a complete energy portfolio with one trusted partner.
Three capacity options help distributors serve different residential storage needs while keeping product planning, training, documentation, and after-sales support within one product family.
Clean, protected connections
A gasketed side cover keeps breakers, terminals, and communication ports protected and neatly out of sight.
Expandable when required
Supports parallel operation of up to 16 units, subject to inverter protocol, BMS compatibility, and correct cable and fuse design.

MORE INFORMATION
Three capacities. One consistent product range.
POSNBAT combines LiFePO4 chemistry, a 51.2 V platform, and CAN / RS485 / dry-contact communication across three published capacities. Importers and distributors can cover entry-level, mid-range, and higher-capacity residential storage requirements within one familiar series.
Service connections sit behind a gasketed side cover, keeping the front clean and professional. Inverter compatibility and parallel configuration must always be confirmed against protocol support, cable sizing, and protection requirements.
SUITABLE APPLICATIONS
Where POSNBAT fits.
- Residential solar self-consumption and daily cycling
- Backup power for essential household loads
- Low-voltage off-grid and hybrid solar systems
- Distributor portfolios requiring several capacities on one platform
Final system suitability depends on inverter compatibility, project engineering, local requirements, and the selected model's published limits.
