3kw Off Grid Inverter with MPPT

3kW off-grid inverter with MPPT is a compact yet powerful solution for small off-grid setups—ideal for tiny homes, remote cabins, RVs, and workshops. It maximizes solar energy harvest via high-efficiency MPPT, delivers stable AC power for essential appliances, integrates with batteries and generators, and ensures reliable energy in locations without grid access. Perfect for users prioritizing efficiency, simplicity, and independence, it cuts reliance on fossil fuels and makes off-grid living accessible.

Products Description

1kw 3kw 5kw 10kw Off Grid Inverter

3kW Stable Power Output: Delivers 3kW continuous AC power (surge capacity up to 6kW for 5 seconds) with pure sine wave output, compatible with sensitive electronics (laptops, TVs) and small appliances (refrigerators, fans, power tools). Optimized for 220V/240V single-phase systems (50/60Hz), matching standard off-grid wiring for small-scale applications.

High-Efficiency MPPT Tracker: Single MPPT channel (max DC input 500V) with 99.0% efficiency, optimizing power extraction from 6-8 x 400W solar panels. Adapts to low light (dawn/dusk), partial shading (common in wooded areas), or cloudy weather, boosting daily energy harvest by 28% compared to basic PWM chargers-critical for off-grid reliability.

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

Battery Compatibility & MPPT Charging: Works with 12V/24V/48V lithium-ion (LiFePO4) and lead-acid batteries (deep-cycle), supporting up to 50kWh storage via parallel connections. MPPT-based 3-stage charging (bulk, absorption, float) prevents overcharging and deep discharge, extending battery life by 25% in off-grid deep-cycle use.

Generator Backup Integration: Built-in generator input (compatible with 3-5kW portable generators) for cloudy periods. Auto-starts generators when battery SOC drops below 20% and shuts off at 80% charge, saving fuel. Manual override option allows user-controlled charging for flexibility.
