xSolar PV Combiner Box – All-in-One AC and DC Energy Enclosure for Hybrid and Off-Grid Systems
This Voltacon all-in-one combiner box brings AC and DC energy paths together in a single IP65-rated enclosure. It is designed for hybrid and off-grid solar systems up to 7kW single phase, handling PV string protection, battery DC isolation, inverter AC protection, EV charger supply and surge protection in one pre-wired unit.
How It Works
The enclosure follows a clear single-line diagram layout. Each power interface has its own protective device and is logically separated from the others:
- Two independent MPPT solar PV strings, protected to 600V DC
- EV charger supply on a dedicated MCB-protected circuit
- Inverter AC output protected for systems up to 7kW single phase
- Dedicated DC isolator for battery connection control
- AC surge protection on both grid/generator input and inverter output
Key Features
- All-in-one AC and DC combiner for solar, battery, grid and EV charging
- Integrated MCBs, RCCBs, contactors and surge protection devices
- IP65 rated PC enclosure: 430 x 330 x 180mm
- PV section: 2-string input and output, up to 600V DC, MC4 connectors
- DC surge protection: 600V DC
- DC PV breaker: 2-pole, 600V, 20A
- Battery DC breaker: 2-pole, 600V, 40A, MC4 connectors
- On-grid inverter AC protection: single phase, up to 7kW
- AC breaker: 1P+N, 230V, 32A
- RCCB: Type B, 2-pole, 40A, 100mA
- Off-grid inverter AC protection: single phase, up to 7kW
- AC contactor: 40A, 230V
- Grid/load AC breaker: 2-pole, 230V, 63A
- Grid/load AC contactor: 63A, 230V
- AC surge protection device: 2-pole, 275V
Applications
- Single phase hybrid solar systems up to 7kW
- Off-grid systems with PV, battery and optional generator or grid backup
- Installations with EV charging requiring a dedicated protected supply
- Systems where a clean, organised AC/DC protection enclosure is required
Installation Notes
Installation must be carried out by a qualified electrician. Verify inverter compatibility and AC/DC ratings before connecting. Type B RCD is required for EV charger applications and is included. All connections must comply with current wiring regulations and local grid connection requirements.
