Features
1.Standard 48V system voltage, perfectly compatible with mainstream home solar inverters; plug & play without extra transformer modification, ideal for household off-grid & grid-tied backup storage.
2.Wall-mounted compact cabinet design, lightweight compared with lead-acid battery; save floor space, easy indoor wall installation for garage, utility room and household cabinet.
3.Wide operating temperature from -35℃ ~ +65℃, high capacity retention under low temperature, stable power supply in cold northern areas and high-temperature tropical regions.
4.Unique sodium-ion zero-volt deep discharge recovery feature; no permanent damage after full depletion caused by long-term power cut or continuous rainy days without solar input.
5.Built-in intelligent BMS for overcharge, over-discharge and short-circuit protection; 6000 long service cycles, non-flammable electrolyte, maintenance-free for daily household use.

FAQ
A：Yes, standard 48V communication protocol matches mainstream solar inverters. Same installation dimension, plug and play without modifying household circuit or inverter
A：Total capacity: 48×200=9600Wh (9.6kWh). Enough to power fridge, lighting, TV and small home appliances for 1 full day for regular family during blackout.
A：Pre-set hanging holes on cabinet, only solid brick/concrete wall needed. No ground occupation, install on garage/utility room wall easily by one worker.
A：Work stably from -40℃~+65℃, ≥85% capacity at -20℃; 3000~6000 charge cycles, normal service life over 10 years for daily solar storage.
A：Sodium ion supports 0V full deep discharge recovery. Even fully drained for weeks due to rainy no-sun weather, battery can be fully restored after recharging without permanent damage.
A:Sample orders start at 1 set, with small batches of 50 sets and large batches of 500 sets or more. We understand the needs of partners of all sizes.
