- This Video shows you how to connect any MPP Solar or similar Inverter in to a computer which does not have a COM port or RS232 port. Most of the modern computers and Laptops does not have an RS232 port, and using this method, you may connect your computer to the Inverter.
Download latest WatchPower software form the below link:
www.mppsolar.c...
Select "Monitoring Software" - "WatchPower for Off-grid"
For the USB-RS232, look for an adapter which supports CTS and RTS. This is usually the issue, and these will usually be full featured RS232.
thx a lot sir for the nice explanation, however I have Must Solar inverter tried to connect it to my laptop but not working, very much appreciate your generous support in advance.
I have a question for you I bought one so I need a computer to install it
What system do you have?
I have WINDOWS 10 and I can't get communication.
what is the chipset of the converter that is working. Thanks and more power.
CH340
@@HappyGreenerWorld Very usefull information, heve other with other chipset expensive that does not work , connecting and disconectin all time with errors
hi, what is your modbus serial settings ? thanks.
Default
Is it compatible for any type of inverter. Like growatt
can you please give me thw link to download the software as i dont have the Disk
Hi, I'm not getting it to connect with my Solar power program. Not sure why
What is the error u get?
@@HappyGreenerWorld no error, just not picking up the inverter
First , test your serial cables with a working serial device such as serial mouse . If it works , then check serial port settings and let me know the outcome
@@HappyGreenerWorld where is serial port settings?
U can use USB cable (old type having micro usb one end) and directly connect inverter and Laptop. There is a micro USB port in the inverter.
Yes! Newer MPP Solar Inverters are coming with mini USB port which you can use to connect to Laptop using any mini-USB to USB connector cable and use WatchPower App. However, Older inverters do not have this mini-USB port and need the above method.
Hi Sir, I have the problem when I plugged in the usb cable, the "monitored devices" is shown nothing in Watchpower software even I have installed the driver for the USB port. may I know any suggested way to solve it? (Urgent)
First, install the latest WatchPower software following the link I have provided in my video description and see if it works. (software on product CD is usually outdated)
Second, check if your Inverter is having Mini-USB port which is available in newer models. If so, just connect a "mini USB to USB" (mobile phone USB cable) and should work without a hassle.
Otherwise, go to device manager and check if the new COM port is correctly configured without any driver error.
If non-of above resolves your issue, then most probably, USB to RS232 connector is defective. You can check the cable by connecting a known RS232 (COM) device such as mouse.
@@HappyGreenerWorld thank you, I have found one problem is due the Rj45 to rs232 cable (gave by developer) is not function well... I going to buy new one... Thank you sir for the valuable guidance..
Hi sir, after I have tried the new cable rj45 to rs232, there is no sign of connection to watch power, Latest Situation: com port functions well, just only when rj45 is connected to the hybrid inverter(only rj45 port available), the watch power cant detect anything. The Com port is not displayed in watch power software. I also try other latest vision watch power software still cannot.
1.Check RJ45 to RS232 cable by connecting it to a PC which has COM port.
2.Check RS232 to USB converter by connecting it to known, working device such as COM mouse.
If above two are successful, then it should work!
@@HappyGreenerWorld Thank you, sir, for the guidelines, it found that the communication board may be broken after I have to do contact the supplier.
i have a PowMr 3000kva invertor.usb to serial cable is available.i want to connect it to my PC.i didnt get any software cd or any things.could i use serial to usb cable for my purpose.
Yes! It should work!
@@HappyGreenerWorld BUT IT DOES NOT the download from the software writer is U/s
Hello. Thank you so much for this video. I have been using the SolarPower program for 3 months, and recently the Charts are not shown anymore. Do you know what it may be the problem?

Thank you in advance

I am using AXPERT Inverter and WatchPower works well with Windows 11 on USB serial port. However a better app called SolarPower does not want to work on USB serial port.
I'm also having the same issue. WatchPower sucks, did you managed to get the SolarPower to work? Or alteast ViewPower?
What interface are you using?
I can't run on windows 10
My problem is, i have lost access to my watchpower account (username and password) to which I've associated my box PN. If I try to create a new account and associate the same PN, I get an error that the PN is already been registered. There's no option to recover password
You can recover password if you are aware and have access to email account used to create the account
@@HappyGreenerWorld If this is possible, please make a video and show it
@@HappyGreenerWorld Only during registration they ask for email for rest password recovery email is not valid
Thank you very much

We have Sunpower inverter same as MPP. When we try to make changes it shows Login password. We dont know the password just installed the software which works. How to bypass this login?
WatchPower software doesnt request login password . Admin password is "Administrator"
Where’s the best place to buy an all in one MPP
Depends on were you live?
I get the wrong time in the wifi module
Pls uss Smart Client App and correct your location on map. Then, time zone will be corrected
Pls see my video on SMART Client and Smart ESS App for more information

Hi, great video.. Can you please tell, I logged in with password administrator. I want to stop the grid feeding since net metering is not yet active.
When I go to paramterer settings 2 and change grid feed to 0kw and apply the settings it again asks for password? Do you know what that password is? Or is there any way to stop grid feeding
