Off-Grid Inverter
Key Features
5kW to 20kW — Full Residential & Small C&I Range Seven models on one 48V platform covering small residential (5kW) to large off-grid commercial (20kW) loads, with single-phase and native three-phase output options.
Single-Phase Parallel → Three-Phase (EU1 Models) EU1 models support parallel operation to build a three-phase system — flexible scaling without replacing hardware as load requirements grow.
High PV Oversizing — Up to 30kW Input F20K accepts 30,000W PV input (1.5× rated output) with dual 1,000V MPPTs, maximizing generation hours and battery charge speed in off-grid installations.
200% Peak Power Capacity All models deliver up to 2× rated peak power (e.g. F12K peaks at 24,000VA) for motor starts and high-inrush loads — essential for pumps, compressors, and HVAC in off-grid systems.
Rich Communication — CAN / RS485 / WiFi / GPRS Standard multi-protocol communication across all models for local monitoring, remote management, and EMS integration. F6K adds dry contact; F5K adds USB.

Common Questions
7 models from 5kW to 20kW, all on a 48V battery platform (40–60Vdc). EU1 models output single-phase 230Vac with parallel-to-three-phase capability; EU3 models output native three-phase 230/400Vac.
EU1 models (F5K / F6K / F10K / F12K) output single-phase 230Vac and support parallel connection to form a three-phase system. The F16K-EU1 also outputs three-phase 230/400Vac. The F12K-EU3 and F20K-EU3 are native three-phase — no parallel needed.
Yes — the F6K carries IP65 outdoor protection and a 5-year warranty, making it the most weather-resistant and warranty-backed model in this series. All other models are IP20 (indoor/protected environments) with 1.5–2 year warranties.
