Whilst solar PV panels are built for durability and are extremely reliable, when something does go wrong with your system, you will want it serviced and repaired as quickly as possible so you don’t lose the cost saving benefits of your solar pv system in Oxford.
But don’t worry, even if someone else has installed you system, we can help you:
The inverter within your solar pv system is generally only built to last 5 years. Its got quite a lot to do as the inverter’s basic function is to “invert” the direct current (DC) output into alternating current (AC). AC is the standard used by all domestic appliances, which is why many view inverters as the “gateway” between the photovoltaic (PV) system and the energy off-taker. Simply put, if your inverter fails or breaks, you won't get any power from your solar panels.
If you system has suddenly stopped working, or you’ve got a red light showing on your inverter, it could well be the inverter that’s stopped. Finding a replacement inverter in Oxford isn’t a problem – we can usually get them replaced very quickly for you so your system gets back up and running without any fuss.
Like with any technology, ensuring your solar pv system is regularly checked and serviced to make sure its running at its optimum can ensure they run up to 30% more efficient by detecting where the system is under performing so repairs and servicing can be implemented. If you spot the electric output dropping, or get any warning lights start flashing, we can be out to you at your property in Oxford and get it back working for you.
We can perform a solar pv system diagnosis check for you so you can find out if your system is running at 100% efficiency at no cost to you. Simply call the number above and we'll be out to your property to conduct a system check and report back any issues we've diagnosed.

Our reputation means a lot to us, so the service we supply to our clients is of utmost importance.
If you’ve already got solar PV added to your property, you probably already know the benefits and have seen the savings and earnings you can make from having solar PV installed.
Unless you have battery storage fitted to your solar PV system, on average you’ll only be using 27% – 32% of the power you are generating. The government pays you for 50% through the Export Tariff no matter how much you use. If we told you that with batteries you could use up to 80% of the energy you created and still get paid for 50% of the energy you’ve generated through the government tariffs we are sure you would be interested!
By having our battery storage system added to your existing solar PV system, not only will it store the energy you’ve generated that you haven’t used, but because its fitted with an intelligent, integrated system that manages the energy you generate effectively and efficiently.
The system works by storing surplus energy in batteries for later use. The system can also be fitted with a built-in EPS (Emergency Power Supply) functionality, allowing the end user to make use of their stored energy in the event of a power outage and can also work as a completely off-grid system.
By storing your power, you can use up to 80% of it, but still receive your 50% Export Tariff as the tariff is based off what your system produces, not what you actually use. It sounds crazy, but this is why a lot of customers with existing solar PV systems are choosing to have battery storage fitted so they save and make even more money.
Whilst solar panels are built for durability and are extremely reliable when something does go wrong with your system, you will want it repaired as quickly as possible so you don’t lose the cost-saving benefits of your solar PV system.
Like with any technology, ensuring your solar PV system is regularly checked and maintained to make sure it’s running at its optimum can ensure they run more efficiently by detecting where the system is underperforming so maintenance can be implemented.
Often you won’t see a problem or spot a difference until you get your electricity bill, when this increase over time it could indicate there is an issue with your system.
In case of emergencies, the PV installation can be forced to stop power generation and be disconnected from the main building electrical supply by carrying out the following steps.
1. Turn the AC isolator marked "PV POINT OF EMERGENCY SWITCHING" to the OFF or "0" position.
2. The AC connection to the inverters will be lost.
3. The inverters will detect the loss of AC, will immediately remove themselves from the AC distribution system and will switch their DC inputs to "open circuit" mode.
4. Turn off the DC isolator(s) at the inverter location.
5. Although DC voltages will still be present in DC cabling there will be no DC current flowing through the cables.
*INVERTER COVERS SHOULD NEVER BE REMOVED UNLESS BY A QUALIFIED ENGINEER*
The cover of the inverter should never be removed unless the unit has been completely isolated from both the DC and AC supplies. Once isolated the inverter cover should not be removed for approximately 30 minutes, this will allow the DC input stage capacitors to fully discharge.
This will ensure that the DC currents are reduced to zero before DC isolations carried out. Breaking a DC current can result in arcing which may cause damage to connectors. NEVER use a plug and socket to switch a DC current. The fully rated DC isolator adjacent to the inverter should be used to complete the DC isolation.
The following steps will result in full and safe isolation of the inverter.
1. Turn the labelled AC isolator adjacent to the inverter to the OFF position.
2. The invertor will then detect the loss of AC, will immediately remove itself from the AC distribution system and will switch its DC input to "open circuit" mode.
3. Turn the DC isolator adjacent to the invert to the OFF or "0" position. This will remove any DC voltage the inverter input connections.
Wait at least 30 minutes before removing the cover if access is required.
*INVERTER COVERS SHOULD NEVER BE REMOVED UNLESS BY A QUALIFIED ENGINEER*
A display of the instantaneous PV system output (in kW) can be obtained from the inverter or in some cases the meter.
This section describes the sequence of actions required to start the PV installation generating electricity from the following initial conditions. In order to prepare the inverters for generation of power, the following steps should be followed to connect the DC supply. It is assumed that these operations are carried out in good light conditions.
1. All PV string cables checked for voltage and polarity and connected to the Dc isolator inputs. All DC cables connected between DC isolators and inverter inputs as per drawing. It is assumed that the system has been previously commissioned by trained personnel.
2. Turn on the DC isolator.
3. Main supply breaker CLOSED (i.e. switched ON).
4. Turn on the AC isolator.
5. After a delay of approximately 3 minutes, during which time the invertor will monitor the grid voltage and frequency. As soon as the inverter has completed the start-up test, the inverter should start to generate power.
6. Full details of invertor front panel LED flash codes are given in the inverter operation manual.
