web interface - is it visible? like in your post above?

This is the ESP32 file system. Do this after flashing the ESP.

That should be changed. So 5.27 on both sides. You need to hit Save to Flash to make mappings permanent Yes - everything works with the previous firmware. The settings are saved. Spot_values_MG2_Tx.png MG 2 sends Spot_values_MG1_Rx.png MG 1 receives can_map_MG2.png But nothing is displayed in the C...

The "pot" and "pot2" parameters are not saved on both controllers (that is, Rx and Tx) after a power failure. Before the power is turned off, everything works and the slave controller receives messages identical to the master. Is this a feature of the firmware? Or am I doing some...

I guess this was bound to happen. With this software there is no way to exchange throttle signal between inverters. Simply due to the lack of a running counter that can be mapped to CAN. This suggests that the board from a Prius (Yaris) with two controllers can no longer be controlled as before, or...

Is this what you mean?

I am loading parameters

I tried it on both controllers. But the "CAN MAPPING" tab does not display anything. But I also noticed this on the old ESP 8266 interface connected to the controller via UART.

Dear! What do you want to achieve? Make the MGR rotate at low voltage with rated torque? Explain. Can I help you? I have 2 MGRs connected to the Auris inverter, all of which are powered by 10 pcs 12 volt lead batteries. Unfortunately, I can’t connect the load to the drive. I uploaded the firmware re...

Are you connecting "EVSE_PP_PIN A7 on the Arduino or Pin 30 on the AMPSeal " to ground?

yes

I think that the program expects EVSE CP PWM #define EVSE_FORCE_INPUT_AMPS 3 //set to 10 - nothing changed 01m51.162s: Command: r 01m51.163s: >> BATTERY_CHARGE_VOLTAGE = 140 01m51.164s: >> OUTPUT_CURRENT_MAX_A = 20 01m51.171s: >> disable_pwm = PWM_ENABLED 01m51.178s: >> wanted_output_voltage = 140.0...

I think your EVSE_FORCE_INPUT_AMPS 0 should be your charging AMPS if not using an EVSE
what is your INPUT_CURRENT_MAX_A?

#define EVSE_FORCE_INPUT_AMPS 3
#define INPUT_CURRENT_MAX_A 25

Hello! So I got back to my charger. So - my configuration: battery - lead 10 * 12 volts(120 volt). The mains voltage is 235 volts, 1 phase is supplied to the rectifier terminals with current sensors. The whole cycle is worked out - but there is no charging current. :( What can be recommendations? Не...

I don't have BMS yet. I'm experimenting with lead batteries
turned off the kanbus and saw - 10:27:39.662 -> 23.112s: >> digitalRead(AC_PRECHARGE_SWITCH_PIN) = TRUE

My actions: 1 I supply 12 volt power to the inverter board - "PRECCHARGE_RELAY" is turned on, as well as "HV_CON" 2 button start I start the inverter - turns on "MAIN_CONN" 3 I pull EVSE_PROX to the ground, in the terminal I give the command "aca 3" - "HV...

With good help - the problem was quickly solved!

and the annoying LM2776 chip in the next edition of the printed circuit board was replaced with a MAX735CSA + T. We continue to continue!

26 volts - there is an unsoldered resistor in the strapping of the converter chip. For some reason, the 5 volt to -5 converter stopped starting at all under load.

instead of 26 volts - 11.5. This is a fiasco. :( I will understand the problem of powering the 26 volt circuit. Here the problem with the -5 volt power supply caused trouble. For some reason, the LM2776 does not want to start when the inverter is running on battery power. If I connect the power supp...

These are the voltages around the operational amplifier.

Everything stopped for me because of the annoying message of the current sensor. messageUART_Charger.png how to set it up? I tried by selecting a voltage divider resistor R2 (12kOhm) - but there is such a narrow resistance range .... And when the inverter is turned on again, this divider parameter i...

That's right. This is how the lock in charging mode will work correctly.

I don't understand your question? The main conctactor is controlled by the inverter. It will activate when you send "start" signal (via CAN or direct on start pin) if dc bus voltage is above "udcsw". There are no other options to my knowledge. Should the charging current go thro...

Gain and offset adjusted. Now the voltage readings are correct. It makes me happy! Now, while I'm looking for a suitable contactor for the AC circuit, I check everything again - and a couple of questions arose. What are your options for controlling the main contactor "MAIN_CONN" ? With a t...

Hello! Help is needed. In the bustle of affairs, I got to the charger and before applying the mains voltage - I would like to clarify a few questions that have arisen. To begin with, my Aqua inverter G9200-52010. 1st question: Wrong measurement of DC BUS voltage 1. In the absence of voltage, the ter...

You have to be a bit careful which pins you use, some conflict with the internal flash memory in the ESP32 module. Edit - also seem to remember that UART1 can conflict with some things too but afraid I can't remember what :( Tried to use GPIO 1, 3. Works. 6-11 seems to be limited when using memory....

Hello everybody! I have a couple of questions: I have GPIOs 16 and 17 connected to MG 1 in my ESP 32. It works! And MG 2 is connected to GPIO 9 and 10. I make changes to the code: #define DBG_OUTPUT_PORT Serial #define INVERTER_PORT UART_NUM_2 #define INVERTER_RX 9 #define INVERTER_TX 10 The followi...
