Product Overview
The Deye 20kW 48V Three Phase Hybrid Inverter is a low-voltage hybrid inverter designed for larger residential, commercial and backup power installations requiring three-phase operation. It combines solar PV, battery storage, grid and generator integration in one platform, with a rated AC input/output active power of 20kW.
Key Features
- 20kW rated three-phase AC input/output active power for higher-demand hybrid solar power systems.
- Supports 40-60V lead-acid or lithium-ion battery systems, with a maximum charging and discharging current of 350A.
- Two MPPT trackers with support for up to 40,000W PV access power and 32,000W maximum PV input power.
- Supports 100% unbalanced output, with maximum output up to 50% of rated power per phase.
- Can be AC coupled to retrofit an existing solar power system.
- Supports up to 10 units in parallel for on-grid and off-grid operation, subject to system design requirements.
- Includes six programmable time periods for battery charging and discharging.
- Supports energy storage from a diesel generator.
Applications
- Three-phase residential properties with higher electrical demand.
- Commercial and light industrial hybrid solar power systems.
- Backup power installations combining solar PV, battery storage, grid and generator sources.
