View options & prices →Before you choose
1
Identify the circuit
Separate the PV array DC circuit from the inverter AC output circuit. Each needs equipment rated for its own application.
2
Record the array design
Have the string count, design voltage and current, inverter details and required protection ready when selecting a DC assembly.
3
Check the AC requirements
Confirm inverter output, direction of power flow, protective-device requirements and metering needs before selecting the AC unit.
Planning an enclosure and components?
Our consumer-unit builder lets you choose single-phase or three-phase, select an enclosure and track the spare DIN space as you add supported components. Custom selections are supplied separately; factory-configured units have their own stated contents.
Build your own consumer unit →Frequently asked questions
Does a solar AC consumer unit protect the DC strings?
No. It serves the inverter AC circuit. Array-side DC switching and protection must be assessed separately.
Are all combiner boxes supplied with the same components?
No. The included switching and protection depend on the selected configuration. Check the product description and datasheet against the required string arrangement.
Does a higher isolator rating increase the circuit rating?
No. Circuit capacity remains limited by the circuit design and protective devices. An isolator's rating does not override the RCBO or MCB rating.
Can I use the same SPD on the AC and DC sides?
No. Choose devices rated for the relevant AC or PV DC application, with voltage and protection characteristics appropriate to that circuit.
