5kw Off-grid Solar Single Phase Inverter With Seamless Integration

5kW off-grid single-phase solar inverter is tailored for medium-sized off-grid homes, cabins, and small farms—delivers stable 220V/240V single-phase AC power, maximizes solar harvest via MPPT, integrates with batteries and generators, and ensures reliable energy where grid access is impossible. It balances performance with simplicity, cutting fuel costs for generators and making off-grid living practical and efficient.

Products Description

Off Grid Inverter

5kW Single-Phase Output: Delivers 5kW continuous AC power (surge capacity up to 10kW for 5 seconds) to handle essential single-phase loads-small air conditioners, refrigerators, washing machines, home offices, and power tools. Optimized for 220V/240V single-phase systems (50/60Hz), matching standard off-grid wiring for residential and small commercial setups.

High-Efficiency MPPT: Single MPPT tracker (max DC input voltage 500V) with 99.0% efficiency, optimizing power extraction from 10-12 x 400W solar panels. Adapts to low light (dawn/dusk) and partial shading (common in wooded or rural areas), boosting daily energy harvest by 28% compared to basic PWM chargers.

Off-Grid Exclusivity: Designed for complete grid independence-no grid-tie functionality, ensuring stable power in remote locations (e.g., mountain cabins, rural homesteads, island properties). Reliably converts solar DC to AC for 24/7 operation, even with variable weather conditions.

Battery Compatibility: Works with 24V/48V lithium-ion (LiFePO4) and lead-acid batteries (deep-cycle), supporting up to 50kWh storage via parallel connections. Intelligent charging algorithms (3-stage: bulk, absorption, float) prevent overcharging and deep discharge, extending battery life by 30% in off-grid cycles.

Generator Integration: Built-in generator input (compatible with 5-7kW portable generators) for backup during extended cloudy periods. Auto-starts generators when battery SOC drops below 20% and shuts off at 80% charge to minimize fuel use, reducing reliance on fossil fuels in remote areas.

Single-Phase Load Stability: Maintains stable 220V/240V output (±2% voltage regulation) for sensitive single-phase electronics (laptops, TVs) and appliances, even with fluctuating loads (e.g., switching on a water heater while running a refrigerator). Prevents voltage spikes that could damage devices.
