MPP solar MPI 5.5Kw

Recommended Posts

Hi everybody, 
first please apologize for my poor english. (I al French)
I have, since december 2017 a MPP solar inverter. It's a 5.5KW MPI serie . This model have two MPPT input (hight voltage MPPT (range 120 to 450 VDC), it's the same as Voltronic InfiniSolar E 5.5KW. I have Solar Power as Software.
As I can't find any forum for it, I post in this one.
One of the MPPT input is dedicated to a Micro hydro turbine with permanant magnet alternator. it's a 3 phase generator, and I use a 3 phase rectifier to convert to DC.
Many people witch are using permanant magnet generator use solar MPPT controler for battery charging.
When I have received the hybrid inverter, it was imposible to connect the software. I was able to send few commands with CommAssistant.exe. After contact with MPP Solar support team, they had to remote control the unit and have changed the serial number with commassistant.Now I can connect the Software.
Now I have a new probleme, I did not saw it before. There is a parameter, I can't change it as I need "factory password", this parameter is "Maximum feed-in grid power" and it's set to 100W. Doest it mean that I can't feed more than 100W into the grid ?
I have also a probleme with the Hydro turbine . The turbine is set to provide around 350W, when I connect 350w bulb, it's working and I can read in 2 multimeter 220W / 1,6A.
But when I connect to hybrid inverter MPPT input,it show only around 100W in the software (PV 1 input power), and turbine increase speed as if she was connected to a small load. I have ordered a few 470uf/450V capacitor, may be the mppt input is disturb with non filtering AC
Does anybody can help me ?
Merci à tous

Hi Cristof

Ma femme peut parler Francaise, et s'il y a quelque chose que vous ne comprenez pas, disez-moi, et je vais demander si elle peut nous aider.

I will try get the password for you. That 100W limit does mean you are limited to 100W.

I would be hesitant to use a solar MPPT on a Hydro or wind turbine, both of which need a dump load which a solar MPPT does not have. Is the hydro turbine a DIY installation?

Hi Chris, 

many thanks for your help.

I had a response from MPP SOLAR. The "100W" setting can be change without password from hybrid front keyboard.

Since I have change it, the MPPT input is working perfectly, in software it show the max power from Hydro turbine.

I have order this inverter beacause it can feed to the grid the extra power.

My turbine is PELTON turbine, DIY, I have a youtube channel and a few video :

I heard that the dams have dropped a further 1% since you started your excavations:D

We had a guy up the street drill a borehole. Took them a week to do it. Now as I recall from growing up on a farm, if you start drilling at 6AM you generally hit water by 10AM and by tonight you're finishing up. So I knew something was up... turns out they struck rock at around 60 meters. Again... where I come from we hit water around 30 meters, so this was new to me. It sounds like people regularly drill up to 100 meters deep for water. Which is insane. My well on the other hand, is so shallow my head sticks out at the top when I'm standing in it. So not even 2 meters.

It's actually amazing that I still have that much water if you think about it...

Close to us in a very affluent area, know of one site, 80-100m borehole. The water quality is also dropping ever so slowly, they know, for they use it as potable water in the house.

Plans are there to go deeper.

does anybody can tell me if I can find the "QPI" commande liste for this hybrid inverter?

I think it may be this one:

^P003PI<cr>: Query protocol ID
Response: ^D00517<CRC><cr>

From this file I just uploaded:
