Off-Grid Inverter
Key Features
Pure Sine Wave Output — US Standard Compatible Delivers clean 120/240Vac pure sine wave output at 50/60Hz, fully compatible with North American appliances, sensitive electronics, motors, and HVAC equipment.
Multi-Source Charging — Solar + Grid + Generator Simultaneously accepts PV, utility grid, and generator input. Intelligent priority management ensures batteries stay charged and loads stay powered regardless of weather or grid availability.
Scalable Parallel Architecture Up to 6 units can be paralleled for higher capacity installations — ideal for growing homes, farms, and light commercial sites that need flexible power scaling without full system replacement.
Dual MPPT with 99.9% Tracking Efficiency Two independent MPPT channels maximize solar harvest from different roof orientations or shading conditions, with up to 99.9% tracking efficiency for minimal energy loss.
Smart Monitoring via Wi-Fi / 4G / RS485 Built-in RS485, CAN, USB, and Dry Contact interfaces plus optional Wi-Fi/GPRS/4G modules enable real-time remote monitoring, firmware updates, and BMS integration through mobile app or SCADA systems.
Fully Certified for North American Market UL1741, IEC62109-1/2, FCC 15 Class B, and RoHS certified — meeting all major US and international safety and EMC requirements for residential and commercial off-grid deployment.

Common Questions
All models except the LPR-F18K-NA3-48PR are single/split-phase units outputting 120/240Vac — compatible with standard North American residential and light commercial wiring. The LPR-F18K-NA3-48PR is a dedicated three-phase model outputting 120/208Vac, designed for commercial facilities, workshops, and three-phase motor loads. If your site runs on a three-phase service panel, choose the F18K-NA3; for standard US home or RV installations, any single/split-phase model applies.
Yes. The F5K, F6.5K, F10K, and F16K models all support 1–6 units in parallel, allowing you to scale output from 5kW up to 96kW (6× F16K) without replacing hardware. Each unit maintains synchronized output via CAN bus communication. This makes the system future-proof — start with one unit and add more as your load or battery bank grows.
All models operate on a 48Vdc battery system (voltage range 40–60Vdc) and are compatible with:
The inverter communicates directly with lithium BMS via CAN or RS485 for automatic charge/discharge management, cell balancing monitoring, and protection coordination.
Yes, the entire series is fully certified for the North American market:
UL1741 is the key US grid-interconnection and off-grid inverter standard required by most US AHJs (Authorities Having Jurisdiction). FCC Class B ensures the unit meets US electromagnetic interference limits for residential environments.
