A: Three installation options available: vertical standalone placement, multi-layer vertical stacking and wall-mounted floor installation. No customized cabinet required and space-saving, applicable for home, commercial stores and equipment rooms.
Recommended installation sites: well-ventilated & dry indoor space such as garage, equipment room and power distribution room. It can be used outdoors with sunshade and rainproof protection, but long-term exposure under direct sunlight, rain or damp closed basement is prohibited.
A: It supports four working modes: grid-tied, off-grid, peak-valley electricity arbitrage and emergency backup power supply.
A: Capacity expansion is available via parallel connection & vertical stacking. Same-model batteries can be paralleled freely while maintaining stable 51.2V low voltage for higher safety.
A: Discharge temperature range: -20℃ ~ 60℃, which supports normal power supply for household appliances under minus temperature in winter.
Charging temperature range: 0℃ ~ 55℃. Forbid forced charging when ambient temperature is below 0℃ to avoid cell damage and service life reduction.
A: Maintenance-free in daily use, just keep environment ventilated and dry. For long-term storage, maintain battery SOC between 50%~70% and top up charge every 3~6 months.
