EG4-18KPV-12LV Inverter + EG4 PowerPro 14.3kWh Battery | 18,000W PV Input | 12,000W AC Output | Indoor / Outdoor | UL1973 & UL9540A Certified
The EG4 18K Battery Storage Bundle is a fully integrated, all-weather energy storage solution combining the EG4 18kPV Hybrid Inverter (Model: EG4-18KPV-12LV) with the EG4 PowerPro 14.3kWh LiFePO4 battery and conduit box — delivering a plug-and-play system engineered for residential solar, commercial backup, off-grid installations, and outdoor deployments. With 18,000W of PV input capacity, 12,000W of continuous AC output, self-heating battery technology for cold climates, and closed-loop inverter-battery communication, this bundle eliminates the need for external charge controllers or transformers. Backed by a 10-year manufacturer's warranty and certified to UL1973 and UL9540A, it is built for energy independence at scale.
Built for Outdoor & All-Weather Operation: The weather-sealed hybrid inverter and all-weather PowerPro battery enclosure are engineered for both indoor and outdoor installation — including extreme temperature environments. The battery's integrated self-heating technology automatically activates in cold climates to maintain optimal charging and discharging performance year-round.
High-Capacity Solar Input & AC Output: The EG4 18kPV inverter accepts up to 18,000W of PV array input and delivers a rock-solid 12,000W of continuous AC output on a 120/240V split-phase configuration — providing ample power for high-demand residential appliances, commercial loads, and critical backup circuits simultaneously.
Expandable LiFePO4 Storage: The included 48V / 280Ah / 14.3kWh LiFePO4 battery can be doubled to 28.6kWh by adding a second EG4 PowerPro unit via optional battery paralleling cables — giving system owners the flexibility to start smaller and scale storage capacity as energy needs grow, without replacing any existing hardware.
Plug-and-Play Installation — No External Controllers Needed: Closed-loop communication between the inverter and battery enables fully automatic, coordinated charge and discharge management straight out of the box — eliminating the need for external charge controllers, transformers, or complex BMS configuration, and dramatically reducing installation time and cost.
LCD Display & App Monitoring: An onboard LCD screen provides real-time visibility into system performance, battery state of charge, PV input, and AC output — with optional app connectivity enabling remote monitoring and control from any smartphone, giving installers and homeowners full system visibility at all times.
Industry-Leading Safety Certifications: Certified to UL1973 and UL9540A, the bundle features dual built-in fire arrestors, an emergency stop function, and LiFePO4 chemistry's inherent thermal stability — providing multi-layer protection against electrical faults, thermal events, and fire hazards throughout the system's 8,000+ cycle lifetime.
The EG4 18kPV Hybrid Inverter manages all energy flows within the system — accepting up to 18,000W of DC solar input, converting it to 120/240V AC for home or business use, and simultaneously directing surplus energy into the PowerPro LiFePO4 battery bank for later use. During grid outages, the system seamlessly switches to battery backup, and the closed-loop communication protocol between inverter and battery ensures that charging rates, voltage limits, and state-of-charge parameters are always precisely coordinated without manual intervention.
Hybrid Inverter & MPPT Solar Charging: The 18kPV inverter's built-in MPPT solar charge controller continuously tracks the maximum power point of the connected PV array, harvesting maximum energy and routing it to loads and battery storage — operating in grid-tied, off-grid, or hybrid backup modes based on grid availability and system configuration.
Closed-Loop Battery Communication: The inverter and PowerPro battery exchange real-time data via a closed-loop communication protocol, automatically adjusting charge current, discharge limits, and cell balancing parameters — ensuring the battery is always operated within safe, optimal parameters for maximum lifespan and efficiency without any manual BMS configuration.
Self-Heating & Thermal Management: In cold ambient conditions, the PowerPro battery's integrated self-heating system automatically warms the LiFePO4 cells to the minimum operating threshold before initiating charging — preventing capacity loss, cell damage, and shortened lifespan that can occur when lithium batteries are charged at sub-zero temperatures.
