Clenergy SPH Inverter Monitoring Guide

Checking your inverter’s efficiency helps to make sure it’s functioning in an optimal way. Clenergy SPH inverters possess a monitoring feature allowing 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 vary, such as the start of a new season, the level of shade above your panels, a fault with your inverter, etc. Despite the general reliability of Clenergy inverters, monitoring your unit frequently will enable you to spot a glitch sooner and get it fixed right away, in order to continue to fully benefit from your solar power system.

Monitoring your Clenergy SPH Inverter

Your Clenergy inverter’s blue power light should be on at daytime to show that the unit is working as it should.

Your inverter’s screen has a black button at the bottom left, which will allow you to scroll through the menu. It will first display the Working Mode section, and then the OP WATT one.

To find out how your inverter is performing, press the button a couple more times, until you land on the KWH section (which should come right after PV VOLT). 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. The last number is the total amount of kWh that your system has generated from the day it was installed until now.

In order to find out how much you produce daily, log this data when you get up in the morning and again when you go to bed at night. The difference between the two figures corresponds to your system’s daily production.

As an 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.

 

How well is your Clenergy SPH inverter performing?

If your system was installed by Solargain, you should have a black handover folder with a document entitled “Solargain Customer User Manual”, which was handed to you on the day of your installation. You can refer to that 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 to be sent a new one.
