FAQ
Why does the name say 5kWh when nominal energy is 5.12kWh?
This model is named 5kWh. The nominal energy rating is 5.12kWh.
Is the wall pack a different battery from the floor pack?
No. Wall and floor are two ways to install the same 51.2V battery.
How long does backup runtime last?
Nominal battery-side runtime is 5.12kWh divided by the connected load. A 500W load is about 10.24 hours. A 1000W load is about 5.12 hours. Inverter losses are not included.
What loads can this model run?
Lights, a Wi-Fi router, a refrigerator, a laptop, a fan, a TV, and small appliances, when the total stays within 3.84kW per pack and within the inverter rating.
Can it work with my inverter?
Only if the inverter accepts 51.2V, stays inside 44.8–57.6V DC, and uses CAN, RS485, or RS232. Send the inverter model with the quote request.
Can the system be expanded?
Yes. Up to 10 units in parallel, from 5.12kWh to 51.20kWh. Confirm the inverter before paralleling.
Should I buy this pack or the 10kWh model?
Use this pack for essential backup around 5.12kWh. Choose the 10kWh model, or parallel more than one of these units, when daily backup needs more than that.
