Video reference. "Solaredge Solar Battery System with Backup Power | UK Homeowners Must See!" is from Evo Renewables, a NICEIC-approved solar and battery installer based in the UK. The video shows a complete SolarEdge Home Battery installation including the DC connection to the Energy Hub inverter, Backup Interface wiring, and commissioning on the SolarEdge monitoring platform, giving a clear picture of what the job involves from start to finish.
1. Surveying the site and verifying Energy Hub compatibility
The installer visits the property before ordering equipment. The first question is whether the existing SolarEdge inverter is an Energy Hub model. The SolarEdge Home Battery is DC-coupled and will only operate with the Energy Hub inverter; an older SolarEdge HD-Wave inverter, or any other inverter brand, cannot accept the battery without an inverter replacement.
Where compatibility is confirmed, the installer assesses the consumer unit for available ways, the cable route from the inverter location to the battery position, and whether backup power is required. Backup capability adds the SolarEdge Backup Interface to the scope and changes the AC wiring arrangement.
2. Determining capacity and confirming module count
The SolarEdge Home Battery is available in a 9.7 kWh module. Systems are commonly installed as a single module, though additional modules can be stacked for a larger household with higher daily consumption or longer backup duration requirements. The installer sizes the system based on actual half-hourly consumption data where available, the solar array output, and the desired backup coverage.
The physical installation space is assessed at this stage. The battery cabinet needs enough clearance for ventilation and maintenance access, and the wall or floor surface must be able to take the cabinet weight. An unheated garage in east Kent is a common location; the installer will flag if ambient winter temperatures could push the battery outside its operating range.
3. Preparing the mounting position and cable entries
The SolarEdge Home Battery cabinet is wall-mounted, typically in a garage, utility room or plant room alongside the inverter. The installer fits the wall brackets, checks that fixings are appropriate for the masonry type, and routes cable entry glands before the cabinet goes on the wall. Getting the cable routes right before mounting is quicker than threading cables through a cabinet that is already fixed in place.
4. Connecting the DC cable to the Energy Hub inverter
The battery DC cable connects to the dedicated battery port on the SolarEdge Energy Hub inverter using the manufacturer's cable assembly and connectors. The installer follows the SolarEdge installation manual for polarity, cable sizing and connector torque values. The DC circuit is de-energised and locked out at the isolator before any connections are made. Once the battery-to-inverter cable is complete and the cabinet is secure, the installation moves to the AC side of the system.
5. Wiring the Backup Interface where backup power is required
The SolarEdge Backup Interface is wired between the consumer unit and the circuits the homeowner wants to power during a grid outage. The installer decides with the homeowner which circuits will be backed up and designs the changeover accordingly. All AC wiring is sized and protected under BS 7671, and the installer simulates a grid failure to confirm the backed-up circuits transfer correctly before commissioning is signed off.
Where backup power is not required, this step is skipped and the installation is simpler: the battery charges and discharges through the Energy Hub inverter AC output to and from the grid.
6. Installing and orienting the CT clamp
A current transformer (CT) clamp fits around the grid import conductor at the consumer unit or meter. Correct orientation matters: a reversed clamp inverts import and export readings, causing the battery to export when it should store and charge when it should discharge. The signal cable routes to the SolarEdge Energy Meter, and the installer verifies the readings on the monitoring portal before the system goes live.
7. Commissioning on SolarEdge monitoring and notifying Part P and DNO
With all connections made and dead tests passed, the installer powers up the system and completes the SolarEdge monitoring platform commissioning sequence. Charge and discharge schedules are configured to match the household's energy tariff. Where a Backup Interface is fitted, backup mode is tested using a simulated grid failure, and the backed-up circuits are confirmed to transfer within the specified switching time.
The installation is notified through the installer's Part P competent person scheme; you receive an Electrical Installation Certificate. DNO notification follows: G98 self-certification applies to systems exporting up to 3.68 kW per phase, with the DNO informed within 28 days. Larger or three-phase systems need G99 pre-approval before the work starts. Keep the EIC and DNO letter with your property documents.
