About Clenergy SPH inverters

Clenergy is an Australian-founded company which designs, produces and commercialises solar energy products worldwide. With 400 employees spread over 6 countries, they offer a range of solar PV solutions for residential and commercial use.

The Clenergy SPH range of inverters includes models with outputs anywhere between 1750 W and 6500 W, although the large majority of the models they have sold in Australia were 1.5kW, 2kW and 3kW units.

We service the entire Clenergy SPH inverter range, including:

  • SPH15
  • SPH20
  • SPH30
  • SPH40
  • SPH60


Checking your inverter’s efficiency helps ensure it is functioning optimally. Clenergy SPH inverters include monitoring features that allow you to verify your unit’s ‘yield’, i.e. the power output generated by your solar PV system. There are many reasons why this number may display variance, for example it being the start of a new season, the level of shade above your panels, or a fault with your inverter. Despite the general reliability of Clenergy inverters it’s still worthwhile to regularly monitor your inverter as doing so frequently will enable you to spot a glitch sooner and get it fixed right away.

Your Clenergy inverter’s blue power light should be on during the day, showing that the unit is working as it should. Your inverter’s screen has a black button in the bottom left, which allows you to scroll through the menu. It first displays the ‘Working Mode’ section, followed by the ‘OP WATT’ one.

This is the complete screen order: OP WATT; PV VOLT; GRID VOLT; GRID FREQ; O/P CUR; X KWH; RATING = X KW; M CPU VER X; S CPU VER X.

To find out how your inverter is performing, press the button until you find the ‘KWH’ section (which should come right after PV VOLT). The last number displayed on this screen is the total amount of kWh your system has generated from the day it was installed until now.

In order to find out how much you’re producing daily, log this data first thing in the morning and again late in the evening. The difference between the two figures corresponds to your system’s daily production.

For example, if your inverter shows 100 kWh at 8:00 am on a given day and 110 kWh at 6:00 pm the same day, your daily production for that day is 110 kWh - 100 kWh = 10 kWh.

To determine your average daily production, record this figure at the start and end of each month and then divide the difference by the number of days in between.

For instance, if your E-Total is 1100 on the 1st of January and 1300 on the 1st of February, your monthly yield for January is 1300 - 1100 = 200 units, and your average daily production in January is 200 units / 31 days = 6.45 kWh per day.

If your system was installed by Solargain, you should have a black handover folder with a document entitled “Solargain Customer User Manual”, given to you on the day of your installation. You can refer to this document to compare your monthly production data with the numbers indicated in the manual and ensure your system is functioning properly. If you’ve lost your manual, please contact Solargain so we can send you a new one.

When there is a major internal issue with your Clenergy SPH inverter, it will display a fault light until fixed. If you find yourself in this situation, we advise you to get in touch with us so we can have one of our qualified technicians visit your property and check your inverter.

Please note: when your inverter turns on in the morning and off in the evening, it will display a red light and will make a clicking noise – this is normal and you shouldn’t be concerned. However, this light should turn off once the sun comes up. If it stays on during the day, you should attempt to reset your inverter. If the fault light remains lit, please contact our service team.

When speaking to our team, please have ready:

  • The error code - displayed on the screen
  • The serial number - printed on the sticker situated on the top of your inverter

If the error messages ‘No Utility’ or ‘Grid Fault’ appears, it could be due to a fuse issue, a power surge or blackout - whatever the case may be, we can repair your inverter. In the case of a Ground Fault, the problem may come from the panel earthing, in which case you'll need to book an inspection and get a quote. An Isolation Fault might be the consequence of water damage, in which case an inverter check and quotation are also required.

If your issue is not mentioned above, chances are you will most likely need to replace your inverter. When you book a health check, our technician will bring a replacement option just in case, so we can get you up and running again without scheduling another site visit, saving you time and money.

Whether or not you bought your Clenergy SPH inverter from us, we’re happy to service it for you. Getting your inverter serviced helps to keep it functional, safe and efficient. Our trained solar specialists are experienced with the SPH inverter range, which enables us to look after your Clenergy system properly. Our ISO 9001 certification shows our dedication to international quality and safety standards so you can trust that we will give you only the best in service and repairs.

Clenergy inverters have a 5-year standard warranty. If you wish to proceed with a warranty claim, we can facilitate it, as long as you can provide the following:

  • Proof of purchase
  • Panel models and quantities
  • Fault code information
  • Serial number from the top of the inverter

If your Clenergy inverter is nearing the end of its warranty, you may want to consider taking this opportunity to upgrade your inverter to newer technology or prepare your home for the future by getting a battery-ready inverter and solar PV system.
