FAQs
What is included with the system?
The core system includes two WT5100 51.2V 100Ah rack batteries and one 6.5kW 120V single-phase inverter. Rack, shelf, cables, protection devices and other installation accessories must match the final system design.
How much energy and power does it provide?
The two WT5100 batteries provide 10.24kWh of nominal storage. The inverter delivers 6.5kW of continuous 120V pure sine wave output and up to 9.75kVA of peak power.
What household loads can the system support?
The system can support compatible 120V loads such as refrigerators, freezers, lights, networking equipment, televisions, microwaves, outlets, room air conditioners and selected tools. Combined running power and starting surge must remain within inverter limits.
Can it power 240V appliances?
No. This package uses a 120V single-phase inverter and must not be connected to 240V electric dryers, ranges, Level 2 EV chargers, central 240V HVAC systems or other 240V loads.
How long can the system provide backup power?
Planning estimates range from approximately 14.9–16.8 hours at a 0.5kW essentials load to 2.5–2.8 hours at a 3kW selected load. Actual runtime varies with load, reserve settings, efficiency, temperature and operating conditions.
How much solar input does the inverter support?
The inverter supports up to 9kW of PV input, a 90–260V MPPT operating range and a 300V maximum PV open-circuit voltage. Actual charging performance depends on array design, weather, orientation and active loads.
Do the batteries include BMS protection?
Yes. Each WT5100 includes an intelligent BMS that monitors voltage, current, temperature and cell balance while providing overcharge, over-discharge, overcurrent and short-circuit protection. CAN and RS485 communication are supported.
Is professional installation required?
Yes. The two batteries weigh approximately 202.8 lb combined and require a supported rack or shelf in a dry location. The wall-mounted inverter requires suitable support and ventilation clearances. The batteries include a 10-year limited warranty and the inverter includes a 5-year limited warranty; terms apply.
