Equipped with a built-in BMS that optimizes charging/discharging, balances cell voltage, and prevents damage—extending battery life by 30%. It supports stackable installation: connect multiple 48V 100Ah units to reach higher capacity (e.g., 2 units = 48V 200Ah, 4 units = 48V 400Ah) for large-scale commercial needs. Optional 4G/WiFi connectivity lets you monitor battery status (voltage, capacity, temperature, health) remotely via a mobile app or web portal—simplifying maintenance and ensuring you’re always aware of power levels.
Its sodium-ion chemistry addresses the biggest pain points of traditional backup batteries: no fire risks, no maintenance headaches, and no performance loss in extreme weather. Lightweight and easy to install (wall-mounted or floor-standing), it’s a hassle-free upgrade from bulky, high-risk lithium-ion or lead-acid systems.
In warehouses, it powers temperature-controlled storage units and inventory tracking systems during outages—preventing spoilage of perishables or loss of inventory data.
“We use this battery for our remote telecom tower. It’s durable, handles extreme temperatures, and lasts twice as long as the lead-acid batteries we used before. Maintenance is zero—we just check the app occasionally. Highly recommend.” – Raj S., Telecom Operations Manager
Q: How long will the 48V 100Ah sodium ion backup battery power my home during an outage?
A: It depends on usage, but for essential appliances (fridge: 150Wh/hour, HVAC: 500Wh/hour, lights: 50Wh/hour), it typically lasts 15–20 hours. For lighter use (only fridge and lights), it can last up to 30 hours.
Q: Is this battery compatible with my existing solar inverter?
A: Yes. It works with most 48V solar inverters (string, micro, or hybrid). Our technical team provides free compatibility checks—just share your inverter model, and we’ll confirm.
Q: Can I install it indoors?
A: Absolutely. Its non-flammable sodium-ion chemistry and enclosed design make it safe for indoor installation (e.g., home garages, commercial utility rooms).
