DC Surge Protection Devices (Spds) Installation Service
DC surge protection devices (SPDs) are installed near to the solar PV inverter. In the event of transient overvoltages, the surge protector will either block excess voltage or bond/short the circuit to earth to avoid the overvoltage damaging the solar inverter and other downstream electrical equipment. To help us prepare a quotation, please email us a picture or two of the solar inverter and any other equipment such as isolators that have been installed nearby.
We supply and install DC Surge Protectors (SPDs) in two form factors:
- Single MPPT:- 1 Circuit, 2 Cables (1 positive, 1 negative)
- Dual MPPT:- 2 Circuits, 4 Cables (2 positive, 2 negative)
QuotationOnce we understand the installation area and which DC surge protection device (SPD) to use for the installation, we will send you a quotation and let you know the earliest date from which the work can be booked in.
Book Installation:Engineers can usually be scheduled to start within 14 days, their names, phone number and the time of their visit will be known to you in advance.
Installation and Commissioning:The installation and commissioning of DC Surge Protection Devices includes DC circuit testing and is usually completed within 2 hours.
Finishing:When the work is complete we will remove and dispose of any rubbish or packaging, recycling as much as we can.
