PV access power and PV input power are separate manufacturer ratings. Confirm the proposed string voltage, current and module arrangement against both limits before installation.
Product Design and Service Access
The compact enclosure combines the display, lower connection cover and integrated mounting arrangement. The views below show the original Deye product, its side controls and the connections described in the manufacturer manual.
DC Switch and Power Control
The side-mounted DC isolator and power on/off button are clearly accessible. Switching, isolation and commissioning must follow the inverter manual.
Controls and Communication Interfaces
The numbered overview identifies the LCD, function buttons, BMS RS485/CAN connection, meter and parallel ports, battery connectors and grid/load/generator connections.
System Integration
The gallery system architecture illustrates PV, battery, grid, backup loads and optional generator or AC-coupled equipment. It shows possible connections; the final design depends on the selected operating mode. The manufacturer wiring instructions and applicable local requirements take precedence.
For a Solarayen LiFePO4 battery pairing, confirm the battery voltage range, continuous current, supported BMS protocol and firmware compatibility. Inverter power alone does not determine battery capacity or backup duration.
Applications
- Residential solar self-consumption with compatible battery storage.
- Backup supply for selected essential circuits within system limits.
- AC-coupled upgrades to suitable existing solar installations.
- Small commercial sites with a compatible single-phase supply.
Frequently Asked Questions
Can I use a 51.2V LiFePO4 battery?
The 48V-class models accept a 40–60V battery range. The battery current limits and BMS communication must also be compatible. Confirm the exact battery and inverter models before ordering.
Does every model have two MPPTs?
No. The 3kW BM1 version has one MPPT. The 3.6–6kW BM2 versions have two. The 24V 3kW variant is also BM1.
Can the inverter charge the battery from a generator?
The series supports energy storage from a compatible diesel generator. Generator rating, connection and operating settings must be matched to the selected system.
What is included in the quotation?
We confirm the exact inverter version, accessories, monitoring option, quantity and delivery terms in the quotation. Battery modules and other system components are specified separately.
What warranty and grid approvals apply?
Deye lists a five-year warranty with up to ten years depending on the installation country and applicable policy. Confirm the warranty and model-specific approval documents for your destination before purchase.
