FAQs
What is included with the system?
The core system includes four WT5100 51.2V 100Ah rack batteries and one 10kW 120/240V split-phase hybrid 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 four WT5100 batteries provide 20.48kWh of nominal storage. The inverter delivers 10kW of rated 120/240V split-phase output and up to 15kVA of peak power.
Can it back up an entire home?
The system can support prioritized household essentials and selected high-demand loads. Actual whole-home coverage depends on simultaneous demand, appliance starting surge, battery reserve and how the backup circuits are configured.
How long can the system provide backup power?
Planning estimates range from approximately 15.1–17.0 hours at a 1kW essential load to 2.1–2.4 hours at a 7.2kW EV charging load. Actual runtime varies with load, reserve settings, efficiency, temperature and operating conditions.
Can it support HVAC, pumps and EV charging?
It can support compatible high-demand loads when voltage, running power and starting surge remain within system limits. Prioritize or stagger HVAC, pumps, electric cooking and EV charging instead of operating every heavy load continuously.
Can it store solar energy for evening use?
Yes. A properly configured system can capture surplus daytime solar energy, offset evening peak demand and preserve a battery reserve for overnight backup. Results depend on solar production, load scheduling and reserve settings.
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 four batteries weigh approximately 405.6 lb combined and require a properly supported rack or shelf in a dry location. The wall-mounted inverter also requires suitable structural support, ventilation clearances and code-compliant electrical installation.
