products DESCRIPTIONPRODUCTS
1. Core Features
High-Efficiency PV Modules: Uses LONGi Hi-MO X10 Explorer 645W panels based on HPBC 2.0 back-contact technology, achieving 23.9% conversion efficiency. Bifacial double-glass design boosts actual power generation.
High-Power Low-Voltage Three-Phase Inverter: The Deye SUN-20K-SG05LP3 delivers 20kW rated output, supports 48V low-voltage batteries, and offers a maximum charge/discharge current of up to 350A, handling high-power charge/discharge demands.
Large-Capacity Storage Configuration: Six 16kWh (51.2V/314Ah) LiFePO4 batteries provide a total capacity of 96kWh. The low-voltage parallel design allows flexible expansion without an additional BMS cabinet.
2. Key Advantages
Three-Phase Unbalanced Output Capability: The inverter supports 100% unbalanced output, with each phase able to deliver up to 50% of rated power. This effectively handles uneven single-phase loads in residential or commercial settings.
Intelligent Energy Management: Supports 6 time periods for battery charge/discharge scheduling, optimizing electricity costs based on time-of-use tariffs. It also features 4ms on/off-grid switching to keep critical loads powered without interruption.
High Scalability and Compatibility: The inverter supports up to 10 units in parallel and is compatible with diesel generator input and AC Coupling for retrofitting existing solar systems—ideal for future expansion or hybrid energy scenarios.
3. FAQs
1. How much load can this system handle without a grid connection?
The inverter supports off-grid operation, and its peak power can reach 2 times the rated power (for 10 seconds), handling startup surges from air conditioners, pumps, etc. However, continuous off-grid load should stay within 20kW, and actual load capacity is limited by battery discharge power.
2. How long can the 96kWh battery capacity roughly meet electricity demand?
This depends on the daily electricity consumption of the home or business. As a reference, if daily consumption is 30–40kWh, a fully charged system can theoretically support 2–3 days of fully off-grid operation (excluding PV charging). Actual runtime should be assessed based on PV generation and load profile.
3. What are the pros and cons of a low-voltage battery (48V) solution compared to a high-voltage battery solution?
Advantages include higher system safety (voltage below 60V), more flexible battery module expansion and replacement, and no need for a complex high-voltage BMS cabinet. Limitations include higher current (350A) at the same power level, requiring thicker cables to control line loss and heat, and typically suiting short-to-medium-term storage configurations—efficiency may be slightly lower than high-voltage solutions in very large-capacity scenarios.
