  1. hello, thanks for your reply, I am also in contact with Jerome in France, about it. His inverter has burned (dc to dc board). regards.
  2. hello, there is no one available to help me find the answer ? Many thanks.
  3. Hello, I have a infinisolar 5,5kw since end of 2017, with a lot of bugs. the main cpu version U1 = 26 second CPU U2 = 30 one of my friend have the same model but from end of 2018, original main cpu and secondary cpu version was 30 and 33 He just update it with 34 and 38 cpu version. I wonder if i can update my inverter (cpu 26 and 30) with 34 and 38 version. Does the 2017 hardware model will accept it ? sory for my bad english. Many thanks.
  4. Hi Coulomb, Here is the first mesage I sent to MPP SOLAR : ""
  5. Hi Coulomb, in recent days, information is spreading in some french photovoltaic forum. we are now realizing that many people bought this inverter model without previous experience with solar systems. Many of these people thought that this was a normal operation. Following a few videos on youtube, a lot of comments from people who are surprised to see these bad results. I do not have any contacts at Voltronic Power, but I have contact with Peggy from Mpp Solar, I sent her a message, she transferred my request to the technical department. I hope to have an answer, or an explanation quickly.
  6. Hi Coulomb, the european seller From "WKS" has send a new inverter (same), and it's still the same. It seems that many peoples in France with this inverter model (Axpert VM III or equal ) have the same problemes. Zero Watts production with light grey sky. The seller is sending is low voltage mppt input (60-115v), we will change the panels wirering to (3 x 3) and will test: https://www.wattuneed.com/fr/onduleurs-et-convertisseurs/9548-onduleur-hybride-wks-evo-5kva-48v-0712971139138.html for sure all the pannel are good. again, thanks for your help, I willgive you news asap
  7. Hello Coulomb, and many thanks for your reply, Sory, but English is not my main language. the inverter come from an european brand, but from voltronic factory. The Brand name is " WKS " https://www.wattuneed.com/fr/onduleurs-et-convertisseurs/12472-onduleur-hybride-wks-evo-ii-5kva-48v-0712971139985.html I think it's a AXPER VM III 5KVA; (similar MPP SOLAR PIP GK series ? ) Hight Voltage MPPT There is 9 PV pannels: one string of 9 for 306V DC Vmpp When the inverter is started, the mppt input on display show 306V for 10 seconds, and drop to 120V (when sky is light grey) : 0 W production. a test has been done with 2 string in parallèle (2 x 4 Pannels), input DC on display about 140V DC, (when sky is light grey) : about 400W production. All PV pannels has been tested , they are all good. In fact, with the same weather, a PIP 5048 with 2 string (2 x 4 "300W"), at the same time was producing more (0w for WKS inverter (drop to 120V), and 650W for PIP 5048). Could you tell me how to find firmware version ? best regards
  8. Hello from France, I allow myself to post this message because many users of hybrid inverters here in France have a problem with their inverter. it's inverters are from the PIP-GE series from mpp solar, but I think they are voltronic power they are hight voltage mppt input all the settings are done correctly, but the mppt algorithm does not seem to work properly. As soon as the panels are no longer in bright sunshine, as soon as the weather is slightly gray, the mppt input drops to 120V DC, and there is no more production. the power sent to the battery or charge is 0 watts. At the same time, with the same configuration of solar panels, an old model PIP5048, at the same place produces it without any problems. yesterday, with a gray sky, the PIP5048 produced more than 850W, while the PIP GE produced absolutely nothing. we currently have 3 inverters of this type that seem defective, they are not of the same brand, but all of the same model as: (2 ar WKS brand, one is Mpp solar). They are all similar as voltronic AXPERT http://voltronicpower.com/en-US/Product/Detail/Axpert-VM-III-1.5KVA-3KVA-5KVA https://www.mppsolar.com/v3/pip-gk-series/ Does anybody could help us. Best regards
  9. Hello everyone,escuse me for my bad english this is a Google translation.10 months ago I bought a MPPSOLAR MPI 5.5KW hybrid inverter. this inverter is the same as the model from infiny solar voltronic power. After a few days of operation, it broke down, error 6. After long discussions with MPP SOLAR, I received a new inverter, the same model. the second comes in turn to break down with the same error code 6. This error code corespond to a temperature error in the charger part (DC to DC board). Whenever they broke down the charger did not charge more than 25A at 62V DC. my batteries are lithium ion, 15S. I found that on the first board DC to DC, one of the MOSFET was exploded (IRFB7730).On the 2nd board the MOSFETs are of another model (CSD19505KCS).On the 2nd board, the Mosfets did not explode, but transil 5KP54A diodes located next to the MOSFETs were disbursed from the board and fell into the bottom of the case. When I looked at the data, I noticed that the temperature had risen to 102 ° C, and this in a few seconds.MPP SOLAR, asked me for photos of the board, and replied that he was going to see with the engineers, but since 10 days, no news, I sent a new email, but no answer for now.‌Do you think I can fix the boards? I can buy MOSFETs and transil diodes, but without any diagrams I do not know if there are other parts to change.Someone can help me.
  10. Thanks for this file. I will test with my hydrid inverter.
  11. Many thanks to Coulomb, but can't download the file,....... I don't have enought point.....
  12. Hi All, does anybody can tell me if I can find the "QPI" commande liste for this hybrid inverter? many thanks
  13. 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 :
  14. 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 ACDoes anybody can help me ?Merci à tous
