FAQ
A single V16 unit provides 16.07kWh of nominal energy (314Ah at 51.2V), replacing up to three standard 5kWh rack batteries. This eliminates parallel DC busbars, reduces cable management complexity, simplifies UL9540 compliance, and speeds up installation time.
Yes. Unlike older 19-inch rack-mounted modules designed strictly for indoor utility rooms, the V16 features an IP66-rated enclosure with C4-M level corrosion resistance. It is engineered for direct outdoor wall-mounting or pad-mounting, resisting dust, heavy rain, and coastal air.
The V16 features an integrated self-heating film that allows charging in temperatures as low as -4°F (-20°C). When charge power (solar or grid) is detected while cell temperatures are below freezing, incoming current is directed to the internal heaters first before battery charging begins.
The V16 incorporates several built-in safety systems directly into the chassis: Aerosol Fire Suppression System:
- Automatically activates in thermal emergencies.
- Integrated DC Breaker & Emergency Shutdown (RSD): Quick-disconnect capability for AHJ code compliance.
- Pre-charge Circuit: Prevents massive inrush current spikes when closing contactors against large inverter capacitor banks.
No. Mixing different capacity cells (e.g., 314Ah cells vs. 100Ah cells) or combining indoor rack modules with the outdoor V16 in the same parallel bank is strictly discouraged. They should be installed in separate battery banks on isolated inverter inputs or separate sub-systems.
Yes, provided the connected hybrid inverter supports high surge capacity. The battery's 200A maximum output (10.24kW continuous) combined with internal pre-charge circuitry accommodates heavy inductive starting loads such as HVAC compressors and well pumps.
Because LFP cell voltage profiles remain virtually flat from 20% to 90%, the BMS calculates SOC via coulomb counting. As voltage reaches 56.4V+ near top end, the BMS reduces charge current to allow passive top-balancing across all internal 314Ah cells before recalibrating to 100%.
The battery is rated for 8,000 cycles (tested at 25°C, 0.5C rate, 90% Depth of Discharge to 70% End of Life) and comes with a 10-year manufacturer warranty.
You can connect up to 16 V16 units in parallel without needing an external Pytes hub, giving a total system capacity of up to 256kWh on a single CAN bus network.
The V16 uses standard CAN/RS485 communication protocols and supports closed-loop integration with leading hybrid/off-grid inverters, including:
- Sol-Ark (e.g., 12K, 15K, 30K)
- Victron Energy (via Cerbo GX / Venus OS)
- Luxpower / EG4
- Deye / Growatt / Schneider Electric
