für das Lademanagement ist der Wechselrichter zuständig, das BMS überwacht die Zellen. Das sind zwei unabhängige Prozesse, dazu müssen WR und BMS nicht kommunizieren.
this can be found at the 2nd answer in this topic:My question is ;if i using AC+PV mode, can i use output load more than 5.5 kw? . Because my house total load using about 7.5kw. Thanks
They are 5.5KW units but will provide more power than that. When it gets hot outside my central air units will kick on and the total load between 2 units, shop and house is over 13,000 watts. They provide the load but of course beeping and warning indicator of overload.
No. This inverter doesnt allow any modifications by software. it must be done in the touch screen.Hi, can you show me how the monitoring with jblance on rpi and Revo works.
I don´t know how tu set up the RPI.
It is posible to control the REVO II with jblance to switch between on and offdrid-mode?
No 11000wats it the peak ac power for a very limited amout of time.Question to the Revo owners:
I am thinking about buying a Revo 5.5k
I am going to build a new solar system which I am planing at this moment. It will be something like this, on the ground but with 9x 380 watts
View attachment 87501
But I am uncertain with some facts
- I am reading several times that the Revo has problems when working without batteries, but I am not sure if this still occures when working in parallel with other units and when working in Offgrid-Mode.
For me I want the Revo to work as single unit and in On-Grid mode just as a Grid tie inverter.
- can the output power limited via software?
- in the datasheet there is a point "surge - 11.000 watts" and I think this should mean "maximum solar power - 11.000 watts". Is this correct?
No. the 5.5kw is the max operating AC power. You can peak that but only for a few second till the inverter shuts down. for 7.5kw you hate to parallel 2 units, to 11kw. ( must be the same software version or the parallel will not work.Hi Guys
for REVO II series 5.5Kw. On/off grid
My question is ;if i using AC+PV mode, can i use output load more than 5.5 kw? . Because my house total load using about 7.5kw. Thanks
Grid limiter will only work with the external CT, and the correct operating mode. The PV must be arround 350volts. I never got it to work consistently without a battery conected, but i found if you enable AC charge of battery it will be more consistent.Question to the Revo owners:

I have iGrid VE II 5.5 Kw and it is possible configure almost all settings programmatically via serial connection. So far, I haven't found a way to reconfigure PV capacity, Peak and Valley, CT sensor calibration. But I don't need change these values dynamically. Thus if you are able to communicate from Raspberry Pi with your iGrid VE II 3k (read values), it could be possible as well. I personally integrated my inverters into the smart home system and dynamically control all parameters including mode depending on the system needs. I haven't connected it directly to my Raspberry Pi but via intermediary components MAX232, ESP12F (own firmware on ESP 8266 implementing MQTT connection via WiFi with my MQTT broker running on Raspberry Pi). Raspberry Pi isn't in the RS232 cable limit distance to the inverters. The main brain of the system is in Raspberry Pi, but some critical functions like safety protection for system overloading is running locally in ESP 8266 to avoid failures in case that WiFi, MQTT or Raspberry Pi is not available. I've already burned many IGBTs, MOSFETs and driver circuits on the main board due to inverter overloads. I control turn off big loads, or at extreme case disconnect the whole home electricity from the inverter using big contractors.Hi guys,
maybe someone can help me with IGrid VE II 3K. Device is just purchased. all works like aliexpres products.
My question is:
There is any possibility change inverter modes (switching between AC mode -> Battery mode and back) via USB from computer or raspberry?
I need scheduled switching between those modes.
Will be very appriciate for any help.
Thank you in advance!
Sorotec said that is 20AHello,
Can anyone tell me what is the max PV current for iGrid VE II 5.5? Could I connect 12 PV panels with V_oc=42V, V_mpp=35V, I_MPP=10.8A, I_SC=11.4A? I guess that connecting them in series would not work due too high VOC=504V>500V(declared maximum). What about in two parallel strings, which would give ISC=22.8A? Does it support such high PV currents?
Thanks.
Have you connected it to PV array? MPPT board is self powered only and it is completely off if there is no PV voltage. In such case V0.0.0 2000-00-00 is reported. You should see MPPT comm timeout in the events.Hi, I unfortunately bought an inverter Easun Revo II
https://www.easunpower.com/products...rid-tied-touch-screen-inverter-with-ct-sensor
I cannot setup with SolarPower software.
Also I think the MPPT have version problem V0.0.0 2000-00-00.
Any help wil be apreciated.
Thanks Dave21, I think they were disconnected. I will try after buying new panels, because I tried some used ones and returned them. I dont have PV array now.Have you connected it to PV array?

The inverter with graphical LCD has communication port connected to display board. The board doesn't use configuration commands supported by SolarPower software. Only read operations of well known parameters work for this inverter.Thanks Dave21, I think they were disconnected.

I connected SolarPower software and after connection with inverter in the Device Control menu disapear MyPower Management option as You can see in the picture. when inverter is disconected apears MyPower option. Any idea?
What is your work mode?Hello. Please help and advice.
I insallled a REVO II 5.5Kw with 8 PV and 2 lithium batteries. The problem i have is that the batteries don't charge even when i have a low load. When i have 500Watt load the input from PV is about 500Watt. When i increase the load, the input power from PV increases to be the same like the load, and when i decrease the load the input power from PV decreases even my batteries are 30%.
However when i cut off the output breaker (i cut off the electricity from home) the input power from PV increases and charges the batteries.
Also when i have electricity from the generator the batteries charges normally!!!!
