Off-Grid Inverter
Key Features
Wide AC Input Compatibility — European Grid Ready Accepts 208/220/230/240V a.c. (L+N+PE) at 50/60Hz, fully compatible with European single-phase grid and generator input across all EU member states and countries following IEC electrical standards.
Pure Sine Wave Output — Protects All Loads Delivers unity power factor pure sine wave output with <10ms switching time, safe for sensitive electronics, motors, medical equipment, and all standard European appliances.
MPPT Solar Charging with High Input Voltage Support Built-in MPPT controller (up to 500Vdc max input) maximizes solar harvest across a wide voltage range. The 12K models feature dual MPPT for multi-string or multi-orientation PV arrays with up to 15kW PV input capacity.
Universal Battery Compatibility Supports lithium-ion and lead-acid batteries across 12V, 24V, and 48V system voltages — compatible with mainstream LiFePO4 battery packs and legacy lead-acid bank installations.
Parallel-Ready for Scalable Systems The 6.5kW and 12kW models support parallel operation, enabling system expansion without replacing the inverter — ideal for growing energy demands on farms, rural homes, and small commercial off-grid sites.
CE Certified — IEC62109 & EN61000 Compliant Full CE certification with IEC62109 safety and EN61000 EMC compliance ensures legal market access and installation approval across Europe. UN38.3 and MSDS documentation available for battery-related export requirements.

Common Questions
The PRO version is an upgrade in enclosure protection and communication interfaces, with the same core power performance:
| Standard (48PS) | PRO (48PS-PRO) | |
|---|---|---|
| Protection Level | IP20 (Indoor only) | IP54 (Splash-proof) |
| Interface | RS485 / CAN | RS485 / RS232 / CAN |
| Operating Temp | -10 ~ +50°C | -10 ~ +60°C |
| Certifications | IEC62109, EN61000 | IEC62109, CE, EN61000 NRS |
Choose PRO for installations in garages, utility rooms, or locations with occasional dust and moisture exposure, or when RS232 communication is required for BMS integration.
The 6.5kW and 12kW models (both standard and PRO) support parallel operation. The 1.2kW and 3.6kW entry-level models do not support parallel function. For large off-grid systems requiring more than 12kW output, multiple 6.5kW or 12kW units can be paralleled to scale capacity as needed.
All models accept both lithium-ion and lead-acid batteries. Battery voltage varies by model:
| Model | Rated Battery Voltage | Battery Voltage Range |
|---|---|---|
| LPR-F1.2K-EU1-12NS | 12V d.c. | 10 ~ 15V d.c. |
| LPR-F3.6K-EU1-24NS | 24V d.c. | 21 ~ 30.2V d.c. |
| LPR-F6.5K / F12K (48PS / PRO) | 51.2V d.c. | 42 ~ 56.4V d.c. |
All models carry CE marking and comply with key EU directives:
These certifications cover residential and light commercial off-grid installations across EU member states and markets following European electrical standards.
