Important: Replacement suitability depends on your PV array voltage, battery chemistry, and communication protocol requirements. Contact support@konmask.com for a verified compatibility assessment.
Why Choose the Original JUSUNG JS-SOL-2442C
- Exact form-factor fit — no mechanical modification required for existing panel cutouts or DIN rail mounts
- Firmware & parameter continuity — retains existing SCADA/HMI communication profiles without reconfiguration
- Proven field reliability — validated in JUSUNG-designed solar systems with matched BMS and inverter pairings
- Warranty compliance — using OEM parts preserves system-level warranty obligations
- Reduced commissioning risk — no re-testing or re-certification required for installed systems
Typical Applications
- Off-grid industrial power systems (telecom base stations, remote monitoring)
- Commercial rooftop solar with battery backup
- Agricultural irrigation pump control systems
- Marine and mobile power systems (24V bus)
- Hybrid solar-diesel generator systems
- Building energy management systems (BEMS) with Modbus integration
System Compatibility
The JS-SOL-2442C is designed to integrate with:
- PV Panels: Standard crystalline silicon and thin-film panels; verify Voc against controller input rating
- Battery Banks: 24V lead-acid (sealed/gel/flooded) and configurable lithium battery packs
- Inverters: Compatible with most 24V pure sine wave inverters; confirm DC bus voltage range
- SCADA/HMI: RS-485 Modbus RTU protocol — compatible with Siemens, Schneider, and standard industrial HMI platforms
- BMS: Verify communication protocol compatibility with your lithium BMS before integration
Selection Guide
Use this guide to confirm the JS-SOL-2442C is the right choice for your application:
