Solar Inverter Replacement: Service

Solar Inverter Replacement: Your Enquiry:

The best place to start is to send us an email or call us with any relevant information that you have available about the current solar inverter and the rest of the solar PV system, a list of things that we like to see (if available) is below. If you`d like to call us whilst you can be in front of the solar inverter, we can talk through an inverter restart and carry out some troubleshooting over the phone, where we`ll likely be able to confirm whether replacing the solar inverter will be appropriate and if so, cover off most of this at the same time:

System size in Watts/Kilowatts:This is the maximumum DC power output that the solar PV system is capable of producing, measured in Watts (W). For example a solar PV system comprising of 16 x 250 Watt solar panels would have a maximum system size of 4000 Watts or 4 kilowatts (kW). This figure can be found on the system`s MCS certificate.

The number, make and model of solar panels:The number and type of solar panels, along with how they have been wired together will determine the voltages (V) and current (A) that the replacement solar inverter will need to be able to work with.

The number of strings/circuits:Solar panels are electrically connected together to form strings/circuits, at the solar inverter end there will be 2 DC cables per circuit (1 positive, 1 negative). So for example if you were to look at the solar inverter, you might see 1 large cable which will be the mains (AC) and 4 smaller DC cables, this would be an indication that the system has 2 x DC strings/circuits. If solar panels are mounted on two or more different roofspaces there would likely be a string/circuit/pair of DC cables for each roofspace.

Pictures and wiring diagrams:Pictures are always really helpful, if you`re able to take and email us a picture or two of the existing solar inverter with everything around it showing all the cables and if possible the nameplate on the current solar inverter and or you have wiring diagrams available, these will usually tell us everything we need to know.

Your address, the installation address (if different):In advance of your instruction, we will provide a written quotation referencing the installation address, we`ll send the specifications of the new solar inverter and any other details specific to your order at the same time.

Equipment delivery and your availability:We are usually able to install replacement solar inverters within 3-4 days and wherever possible we like to send solar inverters out directly to clients to arrive a day or two before our visit. We can be flexible with all of this, so if we need to do things differently please let us know the details with your enquiry.
