Add solar panels to old liquid-cooled energy storage

Can I add battery storage to my existing solar panels?

You can also register to have battery storage added to your existing solar panels to maximise the benefits of your system. Register for free and without obligation before 15 March 2022. Or call us on 0800 060 8509.

Are solar PV and energy storage the same thing?

Solar PV and energy storage are increasingly mentioned in the same breath. Falling costs paired with new revenue streams available to residential and commercial owners is driving storage deployments to new highs.

Can a PV inverter retrofit an AC coupled storage system?

Whatever the case, to retrofit an AC coupled storage system, the PV inverter must be installed such that it is isolated from the grid during an outage by the battery based inverter. To do so, a critical loads panel is added to the facility where the PV inverter is interconnected.

Should I convert my existing PV inverter to a DC coupled system?

Converting to a DC coupled system could require substantial rewiring (both on and off the roof) and deem the existing PV inverter worthless. Instead, contractors should persuade their existing PV customers to consider an AC coupled solution should they opt to add storage.

Can a PV inverter be left alone?

By preserving the PV inverter wiring on the roof can be left alone and the remainder of the installation can be limited to the utility room or point of interconnection. For a more in depth comparison of AC and DC coupling see our article HERE. Most existing PV system are tied into the main service panel of the building.

How does a PV inverter work?

In doing so the PV inverter remains within the system to send AC current from the PV to the battery based inverter (as can be seen in the block diagram above). By preserving the PV inverter wiring on the roof can be left alone and the remainder of the installation can be limited to the utility room or point of interconnection.
