- 1x or 2x Lithium Battery: RUiXU RX-LFP48100 5.12kWh 48V LiFePO4 Server Rack Battery (Choose Standard or Self-Heating Model)
- 1x or 2x Battery Rack Bracket: RUiXU RX-BRACKET Stackable Battery Bracket
- 1x Main Battery Cable Set: RUiXU S200 2-Meter 4AWG Main Battery Cable with Pluggable Connector & 5/16" Ring Lugs
- 6x or 10x Solar Panels: Talesun 445W Bifacial TOPCon N-Type Dual-Glass All-Black Modules (TM7G54M-445)
Note: When selecting the 2x Battery option, intra-battery parallel communication and power interconnect cables (S30 30cm) are included inside the battery boxes.
Battery Options: Standard vs. Self-Heating (Winter-Ready)
Lithium iron phosphate (LiFePO4) batteries require proper ambient temperatures for charging. Select the battery type that best matches your installation location:
- Standard Model (RX-LFP48100): Ideal for indoor installations, heated garages, or mild climates where ambient temperatures remain above freezing (32°F / 0°C).
- Self-Heating Model (RX-LFP48100-H): Designed for unheated sheds, outdoor enclosures, and cold winter environments. Integrated heating pads automatically draw power from the charger to warm the battery cells when temperatures drop ≤41°F (5°C), shutting off automatically once warmed to ≥53.6°F (12°C) for safe, continuous charging.
Key System Features
- Pure 120V Household Power: Easily runs refrigerators, power tools, well pumps, and electronics with 3,600W continuous power and 7,200VA surge capability.
- Bifacial TOPCon Solar Advantage: 445W dual-glass modules capture ambient light from both front and rear sides, generating up to 25% extra power depending on mounting surface.
- Modular & Safe LFP Storage: Cobalt-free IP20 LiFePO4 battery with ≥6,000 cycles @ 90% DOD; stackable design scales seamlessly up to 32 modules.
- Core Wiring Included: Includes the official 2m main battery-to-inverter cable and stackable bracket rack—no need to source main DC battery cables separately.
- Generator Auto-Start Capable: Integrated dry contact relay automatically triggers standby fuel generators when battery levels run low.
